    The left posterior inferior frontal cortex (IFC) is important for syntactic processing, and has been shown in many functional imaging studies to be differentially recruited for the processing of syntactically complex sentences relative to simpler ones. In the non-fluent variant of primary progressive aphasia (PPA), degeneration of the posterior IFC is associated with expressive and receptive agrammatism, however the functional status of this region in non-fluent PPA is not well understood.

    Language disorders can be the first symptom of many neurodegenerative diseases, including Alzheimer's disease (AD) and primary progressive aphasia (PPA). The main variants of PPA are: the non-fluent/agrammatic variant, the semantic variant and the logopenic variant.Several additional variants of PPA, however, have been described and are considered as atypical presentations.We describe the case of a woman presenting a progressive isolated language disturbance, characterized by an early dyspros...

    Primary progressive aphasia (PPA) represents a diverse group of language-led dementias most often due to frontotemporal lobar degeneration. We report clinical, neuropsychological, and neuroimaging data in the case of a 47-year-old woman presenting with non-fluent PPA due to a genetically confirmed pathogenic Presenilin 1 P264L mutation. This case highlights an unusual clinical presentation of familial Alzheimer's disease and a novel presentation of the P264L mutation. The case adds to accumul...

    Left-hemisphere stroke patients often suffer a profound loss of spontaneous speech — known as non-fluent aphasia. Yet, many patients are still able to sing entire pieces of text fluently. This striking finding has inspired mainly two research questions. If the experimental design focuses on one point in time (cross section), one may ask whether or not singing facilitates speech production in aphasic patients. If the design focuses on changes over several points in time (longitudinal section),...

    The left posterior inferior frontal cortex (IFC) is important for syntactic processing, and has been shown in many functional imaging studies to be differentially recruited for the processing of syntactically complex sentences relative to simpler ones. In the non-fluent variant of primary progressive aphasia (PPA), degeneration of the posterior IFC is associated with expressive and receptive agrammatism, however the functional status of this region in non-fluent PPA is not well understood. Our objective was to determine whether the atrophic posterior IFC is differentially recruited for the processing of syntactically complex sentences in non-fluent PPA. Using structural and functional magnetic resonance imaging, we quantified tissue volumes and functional responses to a syntactic comprehension task in eight patients with non-fluent PPA, compared to healthy age-matched controls. In controls, the posterior IFC showed more activity for syntactically complex sentences than simpler ones, as expected. In non-fluent PPA patients, the posterior IFC was atrophic and, unlike controls, showed an equivalent level of functional activity for syntactically complex and simpler sentences. This abnormal pattern of functional activity was specific to the posterior IFC: the mid superior temporal sulcus, another region modulated by syntactic complexity in controls, showed normal modulation by complexity in patients. A more anterior inferior frontal region was recruited by patients, but did not support successful syntactic processing. We conclude that in non-fluent PPA, the posterior IFC is not only structurally damaged, but is also functionally abnormal, suggesting a critical role for this region in the breakdown of syntactic processing in this syndrome.

    Full Text Available Introduction Semantic Feature Analysis (SFA is a treatment for lexical retrieval impairment in which participants are cued by providing semantic information regarding concepts they have difficulty with in naming tasks in an effort to facilitate accurate lexical retrieval (Boyle & Coelho, 1995. People with aphasia are commonly found to have naming deficits and speech-language therapists (SLTs face difficulties in providing an effective treatment method to treat this deficit. This study aims to examine the use of SFA to address naming deficits for nouns and verbs in a Malay patient (KM with non-fluent aphasia. Methods The following tests were administered to the subject pre- and post- treatment: 1 Boston Diagnostic Aphasia Examination (BDAE; 2 Malay Object and Action Test (MOAT; and 3 A series of comprehension and production assessments in Malay. Subject was asked to name 101 and 50 pictures from MOAT. The stimuli were coloured photograph pictures. Treatment and probe (untrained stimuli were selected from pictures that a subject could not name, yielding 40 nouns and 30 verbs. From these, 20 stimuli were randomly chosen as probe items and 20 as treatment stimuli (nouns, 15 treatment and 15 probes (verbs. For the treatment study, single subject A-B-A design was implemented. Three baseline sessions were completed prior to treatment initiation naming for both probe and treatment pictures. Subject attended once-weekly therapy sessions over 8 months. Probes assessing generalizations to untrained pictures were presented at 4th, 8th, and 12th and so on until the end of the programme. Results Results showed that KM’s ability to name trained and untrained picture stimuli improved for both nouns and verbs. KM demonstrated steady improvement in the SFA treatment of trained nouns and verbs: from 5% baseline accuracy to over 90% accuracy at treatment end for nouns and from 0% baseline accuracy to 90% accuracy at treatment end for verbs.

    Full Text Available Introduction Co-verbal gestures can facilitate word production among persons with aphasia (PWA (Rose, Douglas, & Matyas, 2002 and play a communicative role for PWA to convey ideas (Sekine & Rose, 2013. Kong, Law, Kwan, Lai, and Lam (2015 recently reported a systematic approach to independently analyze gesture forms and functions in spontaneous oral discourse produced. When this annotation framework was used to compare speech-accompanying gestures used by PWA and unimpaired speakers, Kong, Law, Wat, and Lai (2013 found a significantly higher gesture-to-word ratio among PWAs. Speakers who were more severe in aphasia or produced a lower percentage of complete sentences or simple sentences in their narratives tended to use more gestures. Moreover, verbal-semantic processing impairment, but not the degree of hemiplegia, was found to affect PWAs’ employment of gestures. The current study aims to (1 investigate whether the frequency of gestural employment varied across speakers with non-fluent aphasia, fluent aphasia, and their controls, (2 examine how the distribution of gesture forms and functions differed across the three speaker groups, and (3 determine how well factors of complexity of linguistic output, aphasia severity, semantic processing integrity, and hemiplegia would predict the frequency of gesture use among PWAs. Method The participants included 23 Cantonese-speaking individuals with fluent aphasia, 21 with non-fluent aphasia, and 23 age- and education-matched controls. Three sets of language samples and video files were collected through the narrative tasks of recounting a personally important event, sequential description, and story-telling, using the Cantonese AphasiaBank protocol (Kong, Law, & Lee, 2009. While the language samples were linguistically quantified to reflect word- and sentential-level performance as well as discourse-level characteristics, the videos were annotated on the form and function of each gesture. All PWAs were

    Full Text Available Abstract Background Focal clusters of slow wave activity in the delta frequency range (1–4 Hz, as measured by magnetencephalography (MEG, are usually located in the vicinity of structural damage in the brain. Such oscillations are usually considered pathological and indicative of areas incapable of normal functioning owing to deafferentation from relevant input sources. In the present study we investigated the change in Delta Dipole Density in 28 patients with chronic aphasia (>12 months post onset following cerebrovascular stroke of the left hemisphere before and after intensive speech and language therapy (3 hours/day over 2 weeks. Results Neuropsychologically assessed language functions improved significantly after training. Perilesional delta activity decreased after therapy in 16 of the 28 patients, while an increase was evident in 12 patients. The magnitude of change of delta activity in these areas correlated with the amount of change in language functions as measured by standardized language tests. Conclusions These results emphasize the significance of perilesional areas in the rehabilitation of aphasia even years after the stroke, and might reflect reorganisation of the language network that provides the basis for improved language functions after intensive training.

It is possible that his greater lesion volume or site did not allow for benefit from a second dose to the same degree as S2. •\tActivation changes (or lack thereof in both cases corresponded with performance on the naming task in the scanner, reflecting the effect of treatment. •\tFor S2, neuroimaging supported the behavioral results which favor a second dose of ILAT.

  20. Measuring the lexical semantics of picture description in aphasia.

    2008-01-01

    BACKGROUND: Individuals with non-fluent aphasia have difficulty producing syntactically laden words, such as function words, whereas individuals with fluent aphasia often have difficulty producing semantically specific words. It is hypothesised that such dissociations arise, at least in part, from a trade-off between syntactic and semantic sources of input to lexical retrieval. AIMS: The aims of this study were (a) to identify quantitative measures of the semantic content of narrative for people with aphasia that are reliable indicators of semantic competence, independent of overall aphasia severity; (b) to determine whether these measures distinguish between fluent and non-fluent aphasia; and (c) to assess whether individuals with fluent and non-fluent aphasia show a trade-off between measures of syntactic and semantic production. METHODS #ENTITYSTARTX00026; PROCEDURES: Connected speech samples were elicited from 16 participants with aphasia, 8 fluent and 8 non-fluent. The semantic sufficiency of the samples was analysed by measuring the proportion of correct information units (CIUs), the type-token ratios (TTRs) of content words, and the proportion of semantically specific ("heavy") to semantically general ("light") verbs produced. These measures were then correlated with syntactic measures from the QPA (Berndt, Wayland, Rochon, Saffran, & Schwartz, 2000) across and within participant groups. OUTCOMES #ENTITYSTARTX00026; RESULTS: CIUs were found to reflect primarily aphasia severity, and not to differentiate between fluent and non-fluent groups. TTRs were also strongly influenced by severity among fluent, but not non-fluent, participants. The ratio of heavy to light verbs reliably distinguished the groups, and showed different patterns of correlation with the syntactic measures. CONCLUSIONS: Results show some evidence for a trade-off between syntactic and semantic inputs to word retrieval, at least among non-fluent participants. The heavy-light verb ratio

    Whereas accuracy levels on the structured task were comparable in the participant’s two languages, he was more accurate in L1 than in L2 on the semi-spontaneous task. Further, production in L1 revealed only tense-selection errors evident only in the structured task; production in L2 included both tense-selection and conjugation errors, and those were found on both tasks. Thus, what may appear as comparable impairment in producing conjugated verbs on a structured test could rather be construed as non-parallel levels of morphological deficit. These findings highlight the importance of considering both tense selection and conjugation across different tasks.

    A common assumption regarding fluency is that the difference between a fluent and non-fluent speaker can be easily stated (Poeck, 1989; Gordon, 1998). However, there is no objective and valid measure to determinate the level of a person with aphasia on the fluency continuum. Traditionally, people with aphasia have been classified as fluent or non-fluent following the cognitive criteria. In ecologycal data we find that 7,3 words-per-turn value is a valid measure in Spanish and Catalan to delim...

  4. Primary progressive aphasia

    2014-01-01

    Primary progressive aphasia (PPA) is a clinical syndrome diagnosed when three core criteria are met. First, there should be a language impairment (i.e., aphasia) that interferes with the usage or comprehension of words. Second, the neurological work-up should determine that the disease is neurodegenerative, and therefore progressive. Third, the aphasia should arise in relative isolation, without equivalent deficits of comportment or episodic memory. The language impairment can be fluent or non-fluent and may or may not interfere with word comprehension. Memory for recent events is preserved although memory scores obtained in verbally mediated tests may be abnormal. Minor changes in personality and behavior may be present but are not the leading factors that bring the patient to medical attention or that limit daily living activities. This distinctive clinical pattern is most conspicuous in the initial stages of the disease, and reflects a relatively selective atrophy of the language network, usually located in the left hemisphere. There are different clinical variants of PPA, each with a characteristic pattern of atrophy. The underlying neuropathological diseases are heterogeneous and can include Alzheimer’s disease as well as frontotemporal lobar degeneration. The clinician’s task is to recognize PPA and differentiate it from other neurodegenerative phenotypes, use biomarkers to surmise the nature of the underlying neuropathology, and institute the most fitting multimodal interventions.

    Full Text Available The effects of noninvasive neurostimulation on brain structure and function in chronic poststroke aphasia are poorly understood. We investigated the effects of intermittent theta burst stimulation (iTBS applied to residual language-responsive cortex in chronic patients using functional and anatomical MRI data acquired before and after iTBS. Lateralization index (LI analyses, along with comparisons of inferior frontal gyrus (IFG activation and connectivity during covert verb generation, were used to assess changes in cortical language function. Voxel-based morphometry (VBM was used to assess effects on regional grey matter (GM. LI analyses revealed a leftward shift in IFG activity after treatment. While left IFG activation increased, right IFG activation decreased. Changes in right to left IFG connectivity during covert verb generation also decreased after iTBS. Behavioral correlations revealed a negative relationship between changes in right IFG activation and improvements in fluency. While anatomical analyses did not reveal statistically significant changes in grey matter volume, the fMRI results provide evidence for changes in right and left IFG function after iTBS. The negative relationship between post-iTBS changes in right IFG activity during covert verb generation and improvements in fluency suggests that iTBS applied to residual left-hemispheric language areas may reduce contralateral responses related to language production and facilitate recruitment of residual language areas after stroke.

    The extent to which non-linguistic auditory processing deficits may contribute to the phenomenology of primary progressive aphasia is not established. Using non-linguistic stimuli devoid of meaning we assessed three key domains of auditory processing (pitch, timing and timbre) in a consecutive series of 18 patients with primary progressive aphasia (eight with semantic variant, six with non-fluent/agrammatic variant, and four with logopenic variant), as well as 28 age-matched healthy controls. We further examined whether performance on the psychoacoustic tasks in the three domains related to the patients’ speech and language and neuropsychological profile. At the group level, patients were significantly impaired in the three domains. Patients had the most marked deficits within the rhythm domain for the processing of short sequences of up to seven tones. Patients with the non-fluent variant showed the most pronounced deficits at the group and the individual level. A subset of patients with the semantic variant were also impaired, though less severely. The patients with the logopenic variant did not show any significant impairments. Significant deficits in the non-fluent and the semantic variant remained after partialling out effects of executive dysfunction. Performance on a subset of the psychoacoustic tests correlated with conventional verbal repetition tests. In sum, a core central auditory impairment exists in primary progressive aphasia for non-linguistic stimuli. While the non-fluent variant is clinically characterized by a motor speech deficit (output problem), perceptual processing of tone sequences is clearly deficient. This may indicate the co-occurrence in the non-fluent variant of a deficit in working memory for auditory objects. Parsimoniously we propose that auditory timing pathways are altered, which are used in common for processing acoustic sequence structure in both speech output and acoustic input. PMID:27060523

While the non-fluent variant is clinically characterized by a motor speech deficit (output problem), perceptual processing of tone sequences is clearly deficient. This may indicate the co-occurrence in the non-fluent variant of a deficit in working memory for auditory objects. Parsimoniously we propose that auditory timing pathways are altered, which are used in common for processing acoustic sequence structure in both speech output and acoustic input. PMID:27060523

Meth-ods 30 stroke patients with chronic aphasia accepted speech therapy for a total of 30 hours. The control group (n=15) accepted routine speech training and the treatment group (n=15) accepted constraint-induced aphasia therapy 3 hours a day. They were assessed with the Western Aphasia Battery (WAB) and the Communicative Activity Log (CAL) before and after treatment. Results The treatment group im-proved significantly in oral expression, naming and repetition function of WAB after treatment (P<0.001), but not significantly in listening understanding (P=0.066);while the control group improved significantly in oral expression (P<0.001). The treatment group also significant-ly improved in CAL (P<0.001). Conclusion Constraint-induced aphasia therapy can significantly improve the speech for stroke patients with chronic aphasia in the short term.

    Full Text Available Aphasia is a complex disorder, frequent after stroke (~38%, with a detailed pathophysiological characterization. Proper approaches are mandatory to devise an efficient rehabilitative strategy, in order to address the everyday life and professional disability. Several rehabilitative procedures are based on psycholinguistic, cognitive, psychosocial or pragmatic approaches, among these with neurobehavioral ratio, the Melodic Intonation Therapy (MIT .Van Eeckhout’s adaptation to the French language (Melodic-Rhythmic Therapy: MRT has implemented the training strategy by adding a rhythmic structure reproducing the French prosody.Purposes of this study were to adapt the MRT rehabilitation procedures to the Italian language and to verify its efficacy in a group of 6 chronic patients (5 males with severe non-fluent aphasia and without specific aphasic treatments at least from 9 months. The patients were treated 4 days a week for 16 weeks, with sessions of 30-40 min. They were assessed 6 months after the end of the treatment (follow-up. The patients showed a significant improvement at the Aachener Aphasie Test in different fields of spontaneous speech, with superimposable results at the follow-up. Albeit preliminary, these findings support the use of MRT in the rehabilitation after stroke. Specifically, MRT seems to benefit from its stronger structure than the available stimulation-facilitation procedures and allows a better quantification of the rehabilitation efficacy.

  11. Aphasia following anterior cerebral artery occlusion

    International Nuclear Information System (INIS)

    We have report two cases of aphasia that had infarcts in the distribution of the left or right anterior cerebral artery, as confirmed by computed tomography. Case 1 is a right-handed, 65-year-old man in whom computerized tomographic scanning revealed an infarction of the territory of the left anterior cerebral artery after the clipping of the anterior communicating artery aneurysm. The standard language test of aphasia (SLTA) revealed non-fluent aphasia with dysarthria, good comprehension, almost normal repetition with good articulation, and a defectiveness in writing. This syndrome was considered an instance of transcortical motor aphasia. Although three years had passed from the onset, his aphasia did not show any improvement. Case 2 is a 37-year-old man who is right-handed but who can use his left hand as well. He was admitted because of subarachnoid hemorrhage from an anterior communicating aneurysm. Because of postoperative spasm, an infarction in the distribution of the right anterior cerebral artery developed. He was totally unable to express himself vocally, but he could use written language quite well to express his ideas and had a good comprehension of spoken language. This clinical picture was considered that of an aphemia. After several weeks, his vocalization returned, but the initial output was still hypophonic. (J.P.N.)

    2015-03-01

    Effects of intensive language action therapy (ILAT) on automatic language processing were assessed using Magnetoencephalography (MEG). Auditory magnetic mismatch negativity (MMNm) responses to words and pseudowords were recorded in twelve patients with chronic aphasia before and immediately after two weeks of ILAT. Following therapy, Patients showed significant clinical improvements of auditory comprehension as measured by the Token Test and in word retrieval and naming as measured by the Boston Naming Test. Neuromagnetic responses dissociated between meaningful words and meaningless word-like stimuli ultra-rapidly, approximately 50 ms after acoustic information first allowed for stimulus identification. Over treatment, there was a significant increase in the left-lateralisation of this early word-elicited activation, observed in perilesional fronto-temporal regions. No comparable change was seen for pseudowords. The results may reflect successful, therapy-induced, language restitution in the left hemisphere. PMID:25403745

    Full Text Available Background: Cerebrovascular disease leading to stroke is the most common cause of aphasia. Speakers with agrammatic non-fluent aphasia have difficulties in production of movement-derived sentences such as passive sentences, topicalized constituents, and Wh-questions. To assess the production of complex sentences, some passive, topicalized and focused sentences were designed for patients with non-fluent Persian aphasic. Afterwards, patients’ performance in sentence production was tested and compared with healthy non-damaged subjects.Methods: In this cross sectional study, a task was designed to assess the different types of sentences (active, passive, topicalized and focused adapted to Persian structures. Seven Persian patients with post-stroke non-fluent agrammatic aphasia (5 men and 2 women and seven healthy non-damaged subjects participated in this study. The computed tomography (CT scan or magnetic resonance imaging (MRI showed that all the patients had a single left hemisphere lesion involved middle cerebral artery (MCA, Broca`s area and in its white matter. In addition, based on Bedside version of Persian Western Aphasia Battery (P-WAB-1, all of them were diagnosed with moderate Broca aphasia. Then, the production task of Persian complex sentences was administered.Results: There was a significant difference between four types of sentences in patients with aphasia [Degree of freedom (df = 3, P < 0.001]. All the patients showed worse performance than the healthy participants in all the four types of sentence production (P < 0.050.Conclusion: In general, it is concluded that topicalized and focused sentences as non-canonical complex sentences in Persian are very difficult to produce for patients with agrammatic non-fluent aphasia. It seems that sentences with A-movement are simpler for the patients than sentences involving A`-movement; since they include shorter movements in compare to topicalized and focused sentences.

    In 1994, the term "Pick complex" was proposed to indicate significant clinical and pathological overlapping between primary progressive aphasia, frontal lobe dementia and corticobasal degeneration. We report the case of a 60-year-old man, who initially presented progressive non-fluent aphasia with orofacial apraxia, and subsequently, over a period of 3 years, developed mutism, pathological laughter, extrapyramidal rigidity, dystonia, alien hand syndrome and bulbar signs. An extensive haematological, immunological and biochemical work up was normal. The results of neuroimaging studies and neuropsychological tests, along with the clinical evolution, finally led us to the ?three in one? diagnosis, supporting the concept of Pick complex.

    2016-01-01

    Full Text Available Anomia is a frequent and persistent symptom of poststroke aphasia, resulting from damage to areas of the brain involved in language production. Cortical neuroplasticity plays a significant role in language recovery following stroke and can be facilitated by behavioral speech and language therapy. Recent research suggests that complementing therapy with neurostimulation techniques may enhance functional gains, even amongst those with chronic aphasia. The current review focuses on the use of transcranial Direct Current Stimulation (tDCS as an adjunct to naming therapy for individuals with chronic poststroke aphasia. Our survey of the literature indicates that combining therapy with anodal (excitatory stimulation to the left hemisphere and/or cathodal (inhibitory stimulation to the right hemisphere can increase both naming accuracy and speed when compared to the effects of therapy alone. However, the benefits of tDCS as a complement to therapy have not been yet systematically investigated with respect to site and polarity of stimulation. Recommendations for future research to help determine optimal protocols for combined therapy and tDCS are outlined.

  16. Spontaneous speech: Quantifying daily communication in Spanish-speaking individuals with aphasia.

    Full Text Available Observable disruptions in spontaneous speech are among the most prominent characteristics of aphasia. The potential of language production analyses in discourse contexts to reveal subtle language deficits has been progressively exploited, becoming essential for diagnosing language disorders (Vermeulen et al., 1989; Goodglass et al., 2000; Prins and Bastiaanse, 2004; Jaecks et al., 2012. Based on previous studies, short and/or fragmentary utterances, and consequently a shorter MLU, are expected in the speech of individuals with aphasia, together with a large proportions of incomplete sentences and a limited use of embeddings. Fewer verbs with a lower diversity (lower type/token ratio and fewer internal arguments are also predicted, as well as a low proportion of inflected verbs (Bastiaanse and Jonkers, 1998. However, this profile comes mainly from the study of individuals with prototypical aphasia types, mainly Broca’s aphasia, raising the question of how accurate spontaneous speech is to pinpoint deficits in individuals with less clear diagnoses. To address this question, we present the results of a spontaneous speech analysis of 25 Spanish-speaking subjects: 10 individuals with aphasia (IWAs, 7 male and 3 female (mean age: 64.2 in neural stable condition (> 1 year post-onset who suffered from a single CVA in the left hemisphere (Rosell, 2005, and 15 non-brain-damaged matched speakers (NBDs. In the aphasia group, 7 of the participants were diagnosed as non-fluent (1 motor aphasia, 4 transcortical motor aphasia or motor aphasia with signs of transcorticality, 2 mixed aphasia with motor predominance, and 3 of them as fluent (mixed aphasia with anomic predominance. The protocol for data collection included semi-standardized interviews, in which participants were asked 3 questions evoking past, present, and future events (last job, holidays, and hobbies. 300 words per participant were analyzed. The MLU over the total 300 words revealed a decreased

    Full Text Available Transcranial direct current stimulation (tDCS has been suggested to improve language function in patients with post-stroke aphasia. Most studies on aphasic patients, however, were conducted with a very limited follow-up period, if any. In this pilot, single-blind study on chronic post-stroke aphasic patients, we aimed to verify whether or not tDCS is able to extend its beneficial effects for a longer period of time (21 weeks after the end of stimulation. Three aphasic patients underwent anodal tDCS (A-tDCS, 20 min, 1.5 mA and sham stimulation (S-tDCS over the left frontal (perilesional region, coupled with a simultaneous naming training (on-line tDCS. Ten consecutive sessions (five days per week for two weeks were implemented. In the first five sessions we used a list of 40 figures, while in the subsequent five sessions we utilized a second set of 40 figures differing in word difficulty. At the end of the stimulation period we found a significant beneficial effect of A-tDCS (as compared to baseline and S-tDCS in all our subjects, regardless of word difficulty, although with some inter-individual differences. In the follow-up period, the percentage of correct responses persisted significantly better until the 16th week, when an initial decline in naming performance was observed. Up to the 21st week, the number of correct responses, though no longer significant, was still above the baseline level. These results in a small group of aphasic patients suggest a long-term beneficial effect of on-line A-tDCS.

    •\tActivity in R posSTG decreased over time for CORR pictures while increasing over time for TR/PR pictures Discussion Short-term intensive treatment followed by a home practice program can produce enduring language improvements that provide rich opportunities for investigating treatment-induced neuroplasticity in aphasia. Given the high degree of individual variability in lesion location/extent, and the resulting variability in aphasia type/severity, it makes sense to examine treatment-induced changes in neural activity patterns within subjects where ‘signature’ patterns of activity are remarkably reliable across time.

  19. Drug treatment of poststroke aphasia.

    2004-03-01

    Impairment of language function (aphasia) is one of the most common neurological symptoms after stroke. Approximately one in every three patients who have an acute stroke will suffer from aphasia. The estimated incidence and prevalence of stroke in Western Europe is 140 and 800 per 100,000 of the population. Aphasia often results in significant disability and handicap. It is a major obstacle for patients to live independently in the community. When recovery from aphasia occurs, it is usually incomplete and patients are rarely able to return to full employment and other social activities. Currently, the main treatment for aphasia is conventional speech and language therapy. However, the effectiveness of this intervention has not been conclusively demonstrated and empirical observations suggest that spontaneous biological recovery may explain most of the improvement in language function that occurs in aphasics. The generally poor prognosis of the severe forms of poststroke language impairment (Broca, Wernicke and global aphasia), coupled with the limited effectiveness of conventional speech and language therapy has stimulated the search for other treatments that may be used in conjunction with speech and language therapy, including the use of various drugs. Dopamine agonists, piracetam (Nootropil), amphetamines, and more recently donepezil (Aricept), have been used in the treatment of aphasia in both the acute and chronic phase. The justification for the use of drugs in the treatment of aphasia is based on two types of evidence. Some drugs, such as dextroamphetamine (Dexedrine), improve attention span and enhance learning and memory. Learning is an essential mechanism for the acquisition of new motor and cognitive skills, and hence, for recovery from aphasia. Second, laboratory and clinical data suggest that drug treatment may partially restore the metabolic function in the ischemic zone that surrounds the brain lesion and also has a neuroprotective effect following

  20. Adaptation to aphasia: grammar, prosody and interaction.

    This paper investigates recurrent use of the phrase very good by a speaker with non-fluent agrammatic aphasia. Informal observation of the speaker's interaction reveals that she appears to be an effective conversational partner despite very severe word retrieval difficulties that result in extensive reliance on variants of the phrase very good. The question that this paper addresses using an essentially conversation analytic framework is: What is the speaker achieving through these variants of very good and what are the linguistic and interactional resources that she draws on to achieve these communicative effects? Tokens of very good in the corpus were first analyzed in a bottom-up fashion, attending to sequential position, structure and participant orientation. This revealed distinct uses that were subsequently subjected to detailed acoustic analysis in order to investigate specific prosodic characteristics within and across the interactional variants. We identified specific clusters of prosodic cues that were exploited by the speaker to differentiate interactional uses of very good. The analysis thus shows how, in the adaptation to aphasia, the speaker exploits the rich interface between prosody, grammar and interaction both to manage the interactional demands of conversation and to communicate propositional content.

  1. Paving the Way for Speech: Voice-Training-Induced Plasticity in Chronic Aphasia and Apraxia of Speech—Three Single Cases

    2014-01-01

    Full Text Available Difficulties with temporal coordination or sequencing of speech movements are frequently reported in aphasia patients with concomitant apraxia of speech (AOS. Our major objective was to investigate the effects of specific rhythmic-melodic voice training on brain activation of those patients. Three patients with severe chronic nonfluent aphasia and AOS were included in this study. Before and after therapy, patients underwent the same fMRI procedure as 30 healthy control subjects in our prestudy, which investigated the neural substrates of sung vowel changes in untrained rhythm sequences. A main finding was that post-minus pretreatment imaging data yielded significant perilesional activations in all patients for example, in the left superior temporal gyrus, whereas the reverse subtraction revealed either no significant activation or right hemisphere activation. Likewise, pre- and posttreatment assessments of patients’ vocal rhythm production, language, and speech motor performance yielded significant improvements for all patients. Our results suggest that changes in brain activation due to the applied training might indicate specific processes of reorganization, for example, improved temporal sequencing of sublexical speech components. In this context, a training that focuses on rhythmic singing with differently demanding complexity levels as concerns motor and cognitive capabilities seems to support paving the way for speech.

    1997-04-01

    We present a case of aphasia due to an ischaemic lesion in the left temporo-occipital region of the brain of a 60 year old right-handed polyglot. Mother tongues: French, Italian, Arabic. Educated at school in English. Languages learnt as an adult: German, Portuguese, Spanish. Language habitually spoken prior to illness: Spanish. His language disorder was of non-fluent type and progressed to an anomic disorder. The non-parallel recovery of languages led to an initial and predominant recovery of English (language at school) followed by French (his first language). This type of non-parallel recovery may be compatible with the inhibition-disinhibition mechanism hypothesis. This would mean that the languages of least recovery are inhibited by raising the threshold of some circuits while still permitting comprehension. PMID:9172921

  8. Lateralization of brain activation in fluent and non-fluent preschool children: A magnetoencephalographic study of picture-naming.

    Directory of Open Access Journals (Sweden)

    Paul Fredrick Sowman

    2014-05-01

    Full Text Available The neural causes of stuttering remain unknown. One explanation comes from neuroimaging studies that have reported abnormal lateralization of activation in the brains of people who stutter. However, these findings are generally based on data from adults with a long history of stuttering, raising the possibility that the observed lateralization anomalies are compensatory rather than causal. The current study investigated lateralization of brain activity in language-related regions of interest in young children soon after the onset of stuttering. We tested 24 preschool-aged children, half of whom had a positive diagnosis of stuttering. All children participated in a picture-naming experiment whilst their brain activity was recorded by magnetoencephalography (MEG. Source analysis performed during an epoch prior to speech onset was used to assess lateralized activation in 3 regions of interest. Activation was significantly lateralized to the left hemisphere in both groups and not different between groups. This study shows for the first time that significant speech preparatory brain activation can be identified in young children during picture-naming and supports the contention that, in stutterers, aberrant lateralization of brain function may be the result of neuroplastic adaptation that occurs as the condition becomes chronic.

    Wernicke's aphasia occurs after a stroke to classical language comprehension regions in the left temporoparietal cortex. Consequently, auditory-verbal comprehension is significantly impaired in Wernicke's aphasia but the capacity to comprehend visually presented materials (written words and pictures) is partially spared. This study used functional magnetic resonance imaging to investigate the neural basis of written word and picture semantic processing in Wernicke's aphasia, with the wider aim of examining how the semantic system is altered after damage to the classical comprehension regions. Twelve participants with chronic Wernicke's aphasia and 12 control participants performed semantic animate-inanimate judgements and a visual height judgement baseline task. Whole brain and region of interest analysis in Wernicke's aphasia and control participants found that semantic judgements were underpinned by activation in the ventral and anterior temporal lobes bilaterally. The Wernicke's aphasia group displayed an 'over-activation' in comparison with control participants, indicating that anterior temporal lobe regions become increasingly influential following reduction in posterior semantic resources. Semantic processing of written words in Wernicke's aphasia was additionally supported by recruitment of the right anterior superior temporal lobe, a region previously associated with recovery from auditory-verbal comprehension impairments. Overall, the results provide support for models in which the anterior temporal lobes are crucial for multimodal semantic processing and that these regions may be accessed without support from classic posterior comprehension regions.

  13. Aphasia caused by intracerebral hemorrhage

    International Nuclear Information System (INIS)

    It is generally accepted that cases of aphasia can be divided into several groups according to verbal fluency, auditory comprehension, and repetition abilities. Although many authors have studied aphasia and its location by means of a CT scan, the primary lesion on a CT scan with regard to the subtypes of aphasia still remains controversial. In this report we present our new CT classification for the syndromes of aphasia and the prognosis. Twenty-one patients with intracerebral hematoma (ICH) were followed up for more than 3 months after onset. ICH was classified according to the mode of the horizontal extension of the hematoma on a CT scan. Four lines were decided as follows: Line (a) is between the anterior horn of the lateral ventricle and the midpoint of the third ventricle; Line (b) is the vertical line to the saggital line which originates from the midpoint of the third ventricle; Line (c) is between the trigone of the lateral ventricle and the midpoint of the third ventricle. The CT classification consisted of 4 types: in Type A, ICH was located anterior to line (a); in Type B, ICH was located between line (a) and line (b); in Type C, ICH was located between line (b) and line (c); Type B+C, was a combination of Type B and Type C. Transcortical motor aphasia belonged to the Type A group. Transcortical sensory aphasia belonged to the Type B and Type B+C groups. Wernicke's and anomic aphasia belonged to the Type C group. Conduction and global aphasia belonged to the Type B+C group. Pure Broca's aphasia could not be observed in this series. Several relationships between the syndromes of aphasia and its CT findings were evident. On the other hand, the syndromes of aphasia and the degree of recovery were not correlated, except for global aphasia. (author)

    Arising from the way the speaker deals with the underlying impairment in situ, trade-offs are thus clearly made between fluency and morpho-syntactic accuracy and complexity. Even though language processing cannot perform in a safe way anymore, the agrammatic speakers rely on still operating executive functions related to pre- or post-articulatory speech monitoring in order to improve morpho-syntactic encoding.

    Recent research suggests that some people with aphasia preserve some ability to learn novel words and to retain them in the long-term. However, this novel word learning ability has been studied only in the context of single word-picture pairings. We examined the ability of people with chronic aphasia to learn novel words using a paradigm that presents new word forms together with a limited set of different possible visual referents and requires the identification of the correct word-object associations on the basis of online feedback. We also studied the relationship between word learning ability and aphasia severity, word processing abilities, and verbal short-term memory (STM). We further examined the influence of gross lesion location on new word learning. The word learning task was first validated with a group of forty-five young adults. Fourteen participants with chronic aphasia were administered the task and underwent tests of immediate and long-term recognition memory at 1 week. Their performance was compared to that of a group of fourteen matched controls using growth curve analysis. The learning curve and recognition performance of the aphasia group was significantly below the matched control group, although above-chance recognition performance and case-by-case analyses indicated that some participants with aphasia had learned the correct word-referent mappings. Verbal STM but not word processing abilities predicted word learning ability after controlling for aphasia severity. Importantly, participants with lesions in the left frontal cortex performed significantly worse than participants with lesions that spared the left frontal region both during word learning and on the recognition tests. Our findings indicate that some people with aphasia can preserve the ability to learn a small novel lexicon in an ambiguous word-referent context. This learning and recognition memory ability was associated with verbal STM capacity, aphasia severity and the integrity

  18. Slowly progressive fluent aphasia

    International Nuclear Information System (INIS)

    Three patients with slowly progressive fluent aphasia are reported. One of the patients presented with memory disturbance. They were characterized clinically by having selective deficits in vocabulary, which resulted in impairment of confrontation naming, and auditory comprehension. MRI showed an atrophy not only in the left temporal lobe (including the superior, middle and inferior temporal gyri), hippocampus, parahippocampual gyrus, and fusiform gyrus, but also in the left parietal lobe. I-123 IMP SPECT and F-18 FDG PET were used to determine regional cerebral blood flow and regional cerebral metabolic rate, respectively. In addition to the decreased tracer uptake in the left temporal and/or parietal lobe, a decreased uptake was seen in the bilateral basal ganglia, the inner side of the temporal lobe (including the bilateral hippocampus), the right anterior temporal lobe, and the left thalamus. These findings may deny the previous thought that lesions are localized in slowly progressive fluent aphasia. Furthermore, noticeable difficulty in naming, i.e., patients unable to recognize the right answer, are considered attributable to widespread lesions from the whole left temporal lobe, including the hippocampus, to the right temporal lobe.

  19. Structural prediction in aphasia

    Full Text Available There is considerable evidence that young healthy comprehenders predict the structure of upcoming material, and that their processing is facilitated when they encounter material matching those predictions (e.g., Staub & Clifton, 2006; Yoshida, Dickey & Sturt, 2013. However, less is known about structural prediction in aphasia. There is evidence that lexical prediction may be spared in aphasia (Dickey et al., 2014; Love & Webb, 1977; cf. Mack et al, 2013. However, predictive mechanisms supporting facilitated lexical access may not necessarily support structural facilitation. Given that many people with aphasia (PWA exhibit syntactic deficits (e.g. Goodglass, 1993, PWA with such impairments may not engage in structural prediction. However, recent evidence suggests that some PWA may indeed predict upcoming structure (Hanne, Burchert, De Bleser, & Vashishth, 2015. Hanne et al. tracked the eyes of PWA (n=8 with sentence-comprehension deficits while they listened to reversible subject-verb-object (SVO and object-verb-subject (OVS sentences in German, in a sentence-picture matching task. Hanne et al. manipulated case and number marking to disambiguate the sentences’ structure. Gazes to an OVS or SVO picture during the unfolding of a sentence were assumed to indicate prediction of the structure congruent with that picture. According to this measure, the PWA’s structural prediction was impaired compared to controls, but they did successfully predict upcoming structure when morphosyntactic cues were strong and unambiguous. Hanne et al.’s visual-world evidence is suggestive, but their forced-choice sentence-picture matching task places tight constraints on possible structural predictions. Clearer evidence of structural prediction would come from paradigms where the content of upcoming material is not as constrained. The current study used self-paced reading study to examine structural prediction among PWA in less constrained contexts. PWA (n=17 who

    Primary progressive aphasia (PPA) presents with aphasia, with or without other minor cognitive dysfunction. We report five patients with PPA to show the correlation between their clinical signs and imaging findings. The patients can be divided into those with nonfluent (group 1) and those with fluent (group 2) aphasia. The characteristic speech impairment was bradylalia in group 1 and word amnesia in group 2. Impairment of comprehension was common but mild in both groups. On MRI, patients in group 1 showed predominantly left frontal and perisylvian atrophy with reduced uptake in the same region on single photon emission computed tomography (SPECT) using technetium-99m hexamethyl propyleneamine oxime ({sup 99m}Tc HMPAO). Patients in group 2 showed left temporal atrophy involving the superior, middle and inferior temporal gyri, hippocampus and parahippocampal gyrus on MRI and reduced uptake in the same region on SPECT. These findings correlated well with the functional anatomy of speech impairment. (orig.). With 4 figs., 1 tab.

    2011-08-01

    There is a growing trend toward dedicated programs designed to improve the lives of people with aphasia and their families. We are referring to these programs collectively as "aphasia centers." These programs purportedly differ from more traditional medically based aphasia rehabilitation. However, there is no directory of aphasia centers and no definition of what constitutes such a program. Therefore, an online survey was designed to identify and describe aphasia centers in the United States and Canada. A 37-question survey was posted online via SurveyMonkey. An introductory letter was distributed by electronic mail to a listserv and mailing lists of programs associated with aphasia. Potential respondents who considered themselves an aphasia center were asked to complete the survey. A total of 33 survey responses were analyzed, and descriptive data were compiled resulting in a description of the following aspects of aphasia centers: demographic information, mission, admission and discharge policies, assessment practices, program logistics, staffing patterns, marketing, funding, and services offered. In addition, a qualitative analysis of written text responses revealed the following key themes that appear to characterize the responding programs: services that differ from traditional aphasia rehabilitation; a sense of community; a holistic focus on quality of life, psychosocial well-being, participation, and social support; the centrality of group interaction; and variety/intensity of services.

    2016-01-01

    Aphasia is a chronic condition that usually requires long-term rehabilitation. However, even if many effective treatments can be offered to patients and families, speech therapy services for individuals with aphasia often remain limited because of logistical and financial considerations, especially more than 6 months after stroke. Therefore, the need to develop tools to maximize rehabilitation potential is unquestionable. The aim of this study was to test the efficacy of a self-administered treatment delivered with a smart tablet to improve written verb naming skills in CP, a 63-year-old woman with chronic aphasia. An ABA multiple baseline design was used to compare CP's performance in verb naming on three equivalent lists of stimuli trained with a hierarchy of cues, trained with no cues, and not trained. Results suggest that graphemic cueing therapy, done four times a week for 3 weeks, led to better written verb naming compared to baseline and to the untrained list. Moreover, generalization of the effects of treatment was observed in verb production, assessed with a noun-to-verb production task. Results of this study suggest that self-administered training with a smart tablet is effective in improving naming skills in chronic aphasia. Future studies are needed to confirm the effectiveness of new technologies in self-administered treatment of acquired language deficits. PMID:26007615

  10. Neuroimaging in the Differential Diagnosis of Primary Progressive Aphasia – Illustrative Case Series in the Light of New Diagnostic Criteria

    International Nuclear Information System (INIS)

    Primary progressive aphasia (PPA) is a progressive language disorder associated with atrophy of the dominant language hemisphere, typically left. Current PPA criteria divide PPA into three variants: non-fluent (nfvPPA), semantic (svPPA) and logopenic (lvPPA). The classification of PPA into one of the three variants may be performed at 3 levels: I) clinical, II) imaging-supported, III) definite pathologic diagnosis. This paper aimed at assessing the feasibility of the imaging-supported diagnostics of PPA variants in the Polish clinical setting with access to magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT) examinations. We present the clinical and neuroimaging data on 6 patients (4 women, 2 men) clinically diagnosed with PPA (3 with nfvPPA and 3 with lvPPA) in whom MRI and SPECT were performed in order to determine if imaging-supported diagnosis could be established in those cases. In 4 individuals (2 with nfvPPA and 2 with lvPPA) clinical diagnosis was supported by neuroimaging (SPECT, albeit not MRI), thus level II of PPA diagnosis could be established in those cases. MRI results were either inconsistent with the clinical diagnosis (Patients 1 and 2) or a mixed pattern of atrophy was observed (Patients 3–6). Imaging-supported diagnosis of PPA variant is more feasible with quantitative analysis of SPECT images than with purely qualitative visual analysis of MRI. Hypoperfusion abnormalities evidenced by SPECT are more variant-specific than patterns of atrophy

    Introduction. Globalization imposes challenges to the field of behavioural neurology, among which is an increase in the prevalence of bilingual aphasia. Thus, aphasiologists have increasingly focused on bilingual aphasia therapy and, more recently, on the identification of the most efficient procedures for triggering language recovery in bilinguals with aphasia. Therapy in both languages is often not available, and, thus, researchers have focused on the transfer of therapy effects from the tr...

  13. Varieties of semantic 'access' deficit in Wernicke's aphasia and semantic aphasia.

    Comprehension deficits are common in stroke aphasia, including in cases with (i) semantic aphasia, characterized by poor executive control of semantic processing across verbal and non-verbal modalities; and (ii) Wernicke's aphasia, associated with poor auditory-verbal comprehension and repetition, plus fluent speech with jargon. However, the varieties of these comprehension problems, and their underlying causes, are not well understood. Both patient groups exhibit some type of semantic 'access' deficit, as opposed to the 'storage' deficits observed in semantic dementia. Nevertheless, existing descriptions suggest that these patients might have different varieties of 'access' impairment-related to difficulty resolving competition (in semantic aphasia) versus initial activation of concepts from sensory inputs (in Wernicke's aphasia). We used a case series design to compare patients with Wernicke's aphasia and those with semantic aphasia on Warrington's paradigmatic assessment of semantic 'access' deficits. In these verbal and non-verbal matching tasks, a small set of semantically-related items are repeatedly presented over several cycles so that the target on one trial becomes a distractor on another (building up interference and eliciting semantic 'blocking' effects). Patients with Wernicke's aphasia and semantic aphasia were distinguished according to lesion location in the temporal cortex, but in each group, some individuals had additional prefrontal damage. Both of these aspects of lesion variability-one that mapped onto classical 'syndromes' and one that did not-predicted aspects of the semantic 'access' deficit. Both semantic aphasia and Wernicke's aphasia cases showed multimodal semantic impairment, although as expected, the Wernicke's aphasia group showed greater deficits on auditory-verbal than picture judgements. Distribution of damage in the temporal lobe was crucial for predicting the initially 'beneficial' effects of stimulus repetition: cases with

    2006-01-01

    Full Text Available Global aphasia is an acquired language disorder characterized by severe impairments in all modalities of language. The specific sites of injury commonly include Wernike′s and Broca′s areas and result from large strokes - particularly those involving the internal carotid or middle cerebral arteries. Rarely, deep subcortical lesions may cause global aphasia. We present three cases with global aphasia due to a more rare cause: left thalamic hemorrhage. Their common feature was the large size of the hemorrhage and its extension to the third ventricule. HMPAO-SPECT in one of the cases revealed ipsilateral subcortical, frontotemporal cortical and right frontal cortical hypoperfusion. Left thalamic hemorrhage should be considered in the differential diagnosis of global aphasia.

  15. Neuroimaging and neurorehabilitation for aphasia patients

    International Nuclear Information System (INIS)

    Recently, low-frequency repetitive transcranial magnetic stimulation (rTMS) which can suppress neural activity of selected brain areas, has been introduced for stroke patients with aphasia as a therapeutic tool. To assess the therapeutic effects of an 11-days in-hospital protocol of intensive speech therapy (ST) combined with low-frequency rTMS on language function in patients with poststroke aphasia. Twenty patients with left-hemispheric stroke and aphasia were included in this study During their 11-day hospitalization, each patient received 10 treatment sessions consisting of 40-min of 1 Hz repetitive low-frequency TMS and 60-min of intensive ST (one session/day), excluding Sundays. The scalp area for stimulation was selected based on functional (f) MRI and determination of the type of aphasia. Repetitive low-frequency-TMS was applied to the inferior frontal gyrus (IFG) for patients with motor-dominant aphasia and to the superior temporal gyrus (STG) for patients with sensory-dominant aphasia. Language function was evaluated by the Japanese version of the Western Aphasia Battery (WAB), the Standard Language Test of Aphasia (SLTA) and the supplementary test of SLTA at one week before admission, 1 hr after the last rTMS session and 4 weeks after discharge from the hospital. On pretreatment fMRI, the most activated areas were in the left hemisphere (n=11) and the right hemisphere (n=9). Aphasia types were sensory-dominant (n=9) and motor-dominant (n=11). The repetitive low-frequency TMS was applied to the right STG (n=5), left STG (n=4), right IFG (n=8) and left IFG (n=3). All patients with motor-dominant aphasia showed improvement while those with sensory-dominant aphasia showed improvement in spontaneous speed only. Our fMRI-based repetitive low-frequency TMS strategy for aphasic stroke patients seems to be a novel neurorehabilitative approach facilitating the reorganization of language function with a low risk of adverse effects.

  1. Ambient experience in restitutive treatment of aphasia

    Jill S McClung

    2010-11-01

    Full Text Available One of the greatest challenges to language rehabilitation is reconciling the fact that the same therapeutic intervention, provided to different individuals with similar types of stroke-induced aphasia, may result in divergent outcomes. In this paper, the authors reviewed existing literature to identify relevant ambient factors – those outside the control of the clinician – that may potentially influence functional language recovery in aphasia and response to treatment. The goal was to develop a clinical history-taking tool to assist clinicians in gathering information germane to each individual’s unique circumstances and environment, elements that may have previously been underestimated, to provide a complete inventory of potentially potent prognostic factors. First, two of the authors, speech-language pathologists experienced in aphasia rehabilitation, identified and categorized factors that seemed likely to influence aphasia outcomes. Then, a wide range of literature was reviewed in an effort to identify factors empirically found to be potent influences on aphasia recovery. Where studies relating these factors to aphasia were not found, relevant research from allied fields that examined recovery from brain injury is reported. Moreover, some factors thought to be potentially potent have yet to be examined. Finally, the ambient factors supported by evidence were categorized as facilitators or barriers to functional improvement, and the Ambient Influences on Outcome Checklist (AOC was developed, including only those factors shown to be potent in the recovery process. It is hoped that this checklist can be used to more broadly assess potential prognostic influences in aphasia restitution, as well as spawn further research.

    Full Text Available Stroke victims tend to prioritize speaking, writing and walking as the three most important rehabilitation goals. Of note is that two of these goals involve communication. This underscores the significance of developing successful approaches to aphasia treatment for the several hundred thousand new aphasia patients each year and over 1 million stroke survivors with chronic aphasia in the U.S. alone. After several years of growth as a research tool, noninvasive brain stimulation (NBS is gradually entering the arena of clinical aphasiology. In this review, we first examine the current state of knowledge of post-stroke language recovery including the contributions from the dominant and non-dominant hemispheres. Next, we briefly discuss the methods and the physiologic basis of the use of inhibitory and excitatory repetitive transcranial magnetic stimulation (rTMS and transcranial direct current stimulation (tDCS as research tools in patients who experience post-stroke aphasia. Finally, we provide a critical review of the most influential evidence behind the potential use of these two brain stimulation methods as clinical rehabilitative tools.

    2012-06-01

    The incidence of cardiovascular disorders and stroke in Australian Aboriginal communities is more than twice as high as non-Indigenous Australians. Approximately 30% of people who survive stroke are left with some level of aphasia, and yet Indigenous Australians appear to be infrequent users of speech-language pathology services, and there is virtually no research literature about the experiences of aphasia for this group of people. This paper presents the stories of living with aphasia for three Indigenous Australian men living in Perth, Western Australia. Their narratives were collected by an Indigenous researcher through in-depth, supported interviews, and were explored using both within-case and cross-case analyses for common and recurring themes. It is argued that there is value for speech-language pathologists, and other health professionals, to be aware of the broad experiences of living with aphasia for Indigenous Australians because their stories are rarely heard and because, as with people with aphasia generally, they are at risk of social isolation and tend to lack visibility in the community. This study explores the key issues which emerge for these three men and highlights the need for further research in this area. PMID:22472033

    2015-01-01

    Current classification of primary progressive aphasia (PPA) encompasses three variants: non-fluent (nfvPPA), semantic (svPPA) and logopenic (lvPPA). Previously lvPPA was regarded as aphasic form of Alzheimer's disease (AD). However, not all patients with lvPPA phenotype present with AD pathology. Despite abundant literature on differentiation of lvPPA from svPPA and nfvPPA, studies comparing lvPPA with AD and mild cognitive impairment (MCI) are scarce. This study aimed at analyzing written descriptive output in lvPPA, AD and MCI. Thirty-five patients participated in the study: 9 with lvPPA, 13 with AD and 13 with MCI. Most aspects of writing performance were comparable in three groups. However, letter insertion errors appeared in 44% patients with lvPPA, while they were absent in AD and MCI. Patients with lvPPA used more verbs than patients with AD. Writing profile may complement other neuropsychological assessment results in the differential diagnosis of lvPPA. Letter insertion errors and frequent verb use may raise a query of lvPPA. PMID:26188940

    Full Text Available Background: Global aphasia without hemiparesis (GAWH is a rare stroke syndrome characterized by the unusual dissociation of motor and language functions. Issues regarding its etio-pathogenesis, lesion sites, and recovery patterns are extensively being debated in contemporary neuroscience literature. Materials and Methods: Four patients admitted in our hospital between 2005 and 2009 with GAWH caused by ischemic stroke were studied retrospectively with emphasis on number and site of lesions, etiology, and recovery patterns. Results: The clinical findings from our subjects showed that GAWH could result from either single/multiple lesions including subcortical lesions. The recovery was rapid, although not complete. One case evolved into Wernicke′s aphasia as seen in earlier studies. Two subjects revealed evolution to transcortical sensory aphasia and one to Broca′s aphasia which is distinct from previous proposals. Two cases showed lack of clinico-anatomic correlation during recovery. Conclusions: GAWH could result from both embolic and large vessel strokes and single or multiple lesions. The recovery pattern may be variable and may show lack of clinico-anatomical correlation indicating anomalous cerebral functional reorganization, questioning the conventional teaching of language representation in the brain.

  11. Primary progressive aphasia: A dementia of the language network

    OpenAIRE

    Mesulam, Marsel

    2013-01-01

    Primary progressive aphasia (PPA) is a clinical syndrome diagnosed when three core criteria are met. First, there should be a language impairment (i.e., aphasia) that interferes with the usage or comprehension of words. Second, the neurological work-up should determine that the disease is neurodegenerative, and therefore progressive. Third, the aphasia should arise in relative isolation, without equivalent deficits of comportment or episodic memory. The language impairment can be fluent or no...

    Hinckley, Jacqueline J

    2016-08-01

    The purpose of this article is to envision how the clinical practice of aphasia management might be done 10 years in the future. The vision of how an individual clinician's daily tasks are changed is built on current trends, including the aging of the population, the life participation approach to aphasia, development and use of evidence-based practices, person-centered care, and technology. To be prepared for the future of these trends, we will need to develop clinical capacity, not only in the number of speech-language pathologists but also most importantly in their competence for using evidence-based practices and training others to support effective communication, including other health care providers. Research needs that will support the future are also described. PMID:27232092

    Dieguez, Sebastian; Bogousslavsky, Julien

    2007-01-01

    At 45 years of age, Charles Baudelaire suffered a left hemispheric stroke that left him with a right hemiplegia and severe aphasia. In this chapter, we investigate the nature of his symptoms, drawing mostly on his own and his contemporaries' correspondence. Before specifically examining his aphasia, we put the poet's life, work, and health in context, notably his tormented mind, his probable syphilitic infection and the intellectual milieu of 19th century France. The time when Baudelaire was struck with aphasia coincides with early discoveries and debates that centered on the nature and implications of this neurological disorder. Many of the questions raised at that time still await definitive answers. Here, we compare Baudelaire's language disorder with recent research that has shed new light on the poet's disease. Most interestingly, we explore the nature of his dramatic use of the expletive Cré nom!, which was the only word he was able to express. Finally, we discuss the links between disease and creativity and dismiss the frequent notion that Baudelaire, in the end, paid the price of his genius. PMID:17495509

    2016-04-01

    Full Text Available Background: Brain perfusion may differ between patients with corticobasal syndrome (CBS with and without aphasia. Methods: Twenty-six (9 males and 17 females; mean age 76 ± 5.3 years patients with CBS were enrolled in the study. Brain MRI and single-photon emission computed tomography were performed in all subjects. Language was evaluated using the Standard Language Test of Aphasia. The patients were divided into two subgroups according to the presence or absence of progressive aphasia. Differences in the regional cerebral blood flow (rCBF between the two groups were detected based on voxel-by-voxel group analysis using Statistical Parametric Mapping 8. Results: All patients exhibited asymmetric motor symptoms and signs, including limb apraxia, bradykinesia, and akinetic rigidity. Of 26 patients, 9 had a clinically obvious language disturbance, characterized as nonfluent aphasia. Almost all CBS patients with aphasia exhibited cortical atrophy predominantly in the left frontal and temporal lobes with widening of the Sylvian fissure on MRI. The rCBF in the left middle frontal gyrus differed significantly between CBS patients with and without aphasia. Conclusion: CBS patients with aphasia exhibit motor symptoms predominantly on the right side and cortical atrophy mainly in the left perisylvian cortices. In particular, left frontal dysfunction might be related to nonfluent aphasia in CBS.

    2016-01-01

    This study examined patterns of acquired dyslexia in Serbian aphasic speakers, comparing profiles of groups with Broca's versus Wernicke's aphasia. The study also looked at the relationship of reading and auditory comprehension and between reading comprehension and reading aloud in these groups. Participants were 20 people with Broca's and 20 with Wernicke's aphasia. They were asked to read aloud and to understand written material from the Serbian adaptation of the Boston Diagnostic Aphasia Examination. A Serbian Word Reading Aloud Test was also used. The people with Broca's aphasia achieved better results in reading aloud and in reading comprehension than those with Wernicke's aphasia. Those with Wernicke's aphasia showed significantly more semantic errors than those with Broca's aphasia who had significantly more morphological and phonological errors. From the data we inferred that lesion sites accorded with previous work on networks associated with Broca's and Wernicke's aphasia and with a posterior-anterior axis for reading processes centred on (left) parietal-temporal-frontal lobes.

  8. Localization of lesions in aphasia, (2)

    International Nuclear Information System (INIS)

    The relationship between the focus and the extent of the lesions and the various symptoms was investigated. 1. Broca aphasics: More than 80% of the group with obvious anarthric components had lesions of the third frontal gyrus involving Broca's area and the lower part of the precental gyrus as well as opercular and insular regions. The size of the lesions of this group was significantly larger than that of the group without marked anarthric components, and the latter was proved to have little localizing value. 2. Wernicke aphasics: The group with poor reading comprehension had cortical and/or subcortical lesions, involving posterior parts of both superior and middle temporal gyri as well as the supramarginal gyrus. On the other hand, lesions of the group with poor auditory comprehension were more anteriorly located and localized in the deep structures. Lesions of the group with poor Token test scores were large and scattered more anteriorly and/or posteriorly compared with those of the group with good Token test scores. 3. Amnestic aphaiscs: The group with poor naming scores had somewhat larger lesions than the group with good naming scores, and the lesions were scattered about the left hemisphere. The finding has proved that both groups had little localizing value. 4. Conduction aphasics: Lesions of the non-fluent type were significantly larger than those of the fluent type and distributed more anteriorly. However, highly involved lesions were located in the supramarginal gyrus and posterior parts of superior and/or middle temporal gyri. 5. Global aphasics: Lesions of the group with good articulation and prosody were observed to distribute more posteriorly in comparison with those of the other global aphasics. (J.P.N.)

    Full Text Available Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology.Consecutive 100 stroke patients with aphasia admitted in Valie Asr hospital, Khorasan in 2003 enrulled in this prospective study. Diagnosis of stroke and aphasia was made by a neurolosist and topography of involved cerebrovascular territories confirmed by topographic maps of brain in CT scan. Global, Broca and Wernicke subtypes of aphasia constituted 52%, 40% and 6% of the cases respectively. Based on the usual nourishment of Broca and Wernicke areas by anterior and posterior cortical branches of the middle cerebral artery, 79% of Global, 47% of Broca and 50% of Wernicke aphasias had a compatible infarct topography. Other cases had no congruent infarct topography with involved linguistic area of their brain. Specific cerebrovascular topography for subtypes of aphasia in stroke patients was not found. The effects of cerebrovascular lesions on linguistic functions are not predictable by their topography in CT scan.

    1983-09-01

    The ability of aphasic patients to draw from memory objects with a characteristic shape has been investigated. Their capacity to reproduce the form of real objects was studied by showing them for a short time line drawings of simple objects. When the patient had analysed and recognized the figure, the model was hidden from view and the subject was asked to draw the same object from memory. This Drawing from Memory task was administered to 54 aphasics, 67 patients with right hemisphere lesions, 44 nonaphasic left brain-damaged patients and 23 normal controls. The influence of visuoconstructive disabilities was controlled by administering to the same patients a standard test for constructional apraxia (copying 10 geometrical figures). The severity and clinical form of the aphasia and the presence of semantic-lexical impairment at the receptive level were also examined in the aphasic patients. The following results were obtained. (1) Aphasic patients scored significantly less well than the control groups on the Drawing from Memory task and the intergroup differences became greater when the scores from the test for constructional apraxia were included by an analysis of covariance. (2) No significant correlation was detected between the severity and clinical form of the aphasia and the scores obtained on the Drawing from Memory task. (3) There was a significant correlation between impaired drawing from memory and disruption at the semantic-lexical level of language integration. PMID:6640272

    This paper describes preliminary studies on a screening test for aphasia which takes 3-10 minutes to complete and which is suitable for use by general practitioners, junior medical staff and other non-specialists. Data are presented to show that it is a reliable, valid assessment. Using cut-off values derived from normal people, the test is sensitive, but its specificity is limited by such associated factors as hemianopia. Using cut-off values derived from patients known to have aphasia, its specificity is improved. An abnormal result needs to be interpreted in the light of all available clinical information. The test should help identify patients with linguistic disturbance. PMID:2440825

  15. Type of aphasia and regional cerebral blood flow

    International Nuclear Information System (INIS)

    In 40 patients with aphasia due to cerebral infarction, regional cerebral blood flow (rCBF) was measured after 2 months of ictus with 133Xe inhalation method. There were 18 cases with motor aphasia and 22 with sensory aphasia. On the measurements of rCBF, 3 detectors were placed over frontal region (group F), 3 over temporal region (group T), and remaining 3 over parietal region (group P), of the dominant hemisphere. The flow values were compared with the rCBF values obtained from 21 control subjects who had no abnormality in CT scan and on neurological examinations. The control subjects revealed the hyperfrontal pattern of flow distribution; rCBF values in groups F, T and P, which were expressed as an initial slope index, were 50.0 +- 4.8, 48.0 +- 5.1 and 47.4 +- 4.5, respectively. The hyperfrontal pattern was absent in cases with motor aphasia. In this group, rCBF in groups F, T and P were 42.0 +- 8.3, 44.7 +- 8.4 and 41.0 +- 8.5, respectively, and rCBF in frontal region was significantly reduced compared with that in the control group. In sensory aphasia, rCBF values in groups F, T and P were all significantly reduced compared to the controls showing 44.0 +- 5.7, 42.8 +- 5.1 and 40.6 +- 5.4, respectively. In this group, the hyperfrontal pattern was maintained at a low flow level. When absolute rCBF values were compared between motor and sensory aphasia, there was no significant difference between these 2 groups. However, regional flow distribution in motor aphasia was significantly different from that of sensory aphasia, and the cases having the lowest value in group F were more frequently found in the former than in the latter.

  20. A study on regional cerebral circulation in stroke patients with aphasia

    International Nuclear Information System (INIS)

    To study the pathophysiology of aphasia due to cerebral stroke, regional cerebral blood flow (rCBF) was measured by the 133Xe clearance method and the volume of low density area (LDA) was estimated on the basis of computerized tomography in 43 thrombotic (24 aphasia and 19 non-aphasia), 30 hemorrhagic (16 aphasia and 14 non-aphasia) and 6 non-stroke cases. 1) In the healthy hemisphere, rCBF showed no significant difference between aphasia and non-aphasia in both thrombotic and hemorrhagic cases. In the affected hemisphere, thrombotic cases showed significantly decreased rCBF in aphasic cases as compared to non-aphasic, however, hemorrhagic cases revealed no difference. 2) LDA volume showed no significant difference between aphasia and non-aphasia in cerebral thrombosis, however, LDA volume in non-aphasia was smaller than that in aphasia in cerebral hemorrage. 3) Significant differences in the pathophysiology of aphasia due to cerebral stroke were recognized between cerebral thrombosis and cerebral hemorrhage. Such differences should be taken into consideration in the management and treatment of aphasia caused by cerebral stroke. (author)

Current diagnostic criteria require the language dysfunction to remain isolated for at least two years, and to remain the salient feature as the disease progresses, usually to involve other domains such as behavior, executive functions, and judgment. Although PPA in its early stages can usually be differentiated from probable Alzheimer’s disease (PRAD and the behavioral variant of frontotemporal lobar degeneration by the absence of significant changes in memory and behavior, and the preservation of activities daily living, progression of the disease often leads to deficits more consistent with the latter. Underlying etiologies remain heterogeneous: the neuropathological characteristics associated with frontotemporal lobar degeneration, cortocobasal degeneration, and motor neuron disease are usually found. There is a strong genetic susceptibility with affliction of first-degree relatives with similar disease in up to 40 to 50% in some series. Pathogenic mutations in genes coding for the proteins tau and progranulin have been isolated. These are leading to a better understanding of the neuropathological mechanisms and hopefully targeted disease-modifying therapy. Current therapy is limited to improving mood symptoms and targeting behavior changes as they develop. Referral to specialized centers where speech therapy, counseling, and education

    Recovery from aphasia, loss of language following a cerebrovascular incident (stroke), is a complex process involving both left and right hemispheric regions. In our study, we analyzed the relationships between semantic processing behavioral data, lesion size and location, and percent signal change from functional magnetic resonance imaging (fMRI) data. This study included 14 persons with aphasia in the chronic stage of recovery (six or more months post stroke), along with normal controls, who performed semantic processing tasks of determining whether a written semantic feature matched a picture or whether two written words were related. Using region of interest (ROI) analysis, we found that left inferior frontal gyrus pars opercularis and pars triangularis, despite significant damage, were the only regions to correlate with behavioral accuracy. Additionally, bilateral frontal regions including superior frontal gyrus, middle frontal gyrus, and anterior cingulate appear to serve as an assistive network in the case of damage to traditional language regions that include inferior frontal gyrus, middle temporal gyrus, supramarginal gyrus, and angular gyrus. Right hemisphere posterior regions including right middle temporal gyrus, right supramarginal gyrus, and right angular gyrus are engaged in the case of extensive damage to left hemisphere language regions. Additionally, right inferior frontal gyrus pars orbitalis is presumed to serve a monitoring function. These results reinforce the importance of the left hemisphere in language processing in aphasia, and provide a framework for the relative importance of left and right language regions in the brain.

  3. Maladaptive Plasticity in Aphasia: Brain Activation Maps Underlying Verb Retrieval Errors.

    Spielmann, Kerstin; Durand, Edith; Marcotte, Karine; Ansaldo, Ana Inés

    2016-01-01

    Anomia, or impaired word retrieval, is the most widespread symptom of aphasia, an acquired language impairment secondary to brain damage. In the last decades, functional neuroimaging techniques have enabled studying the neural basis underlying anomia and its recovery. The present study aimed to explore maladaptive plasticity in persistent verb anomia, in three male participants with chronic nonfluent aphasia. Brain activation maps associated with semantic verb paraphasia occurring within an oral picture-naming task were identified with an event-related fMRI paradigm. These maps were compared with those obtained in our previous study examining adaptive plasticity (i.e., successful verb naming) in the same participants. The results show that activation patterns related to semantic verb paraphasia and successful verb naming comprise a number of common areas, contributing to both maladaptive and adaptive neuroplasticity mechanisms. This finding suggests that the segregation of brain areas provides only a partial view of the neural basis of verb anomia and successful verb naming. Therefore, it indicates the importance of network approaches which may better capture the complexity of maladaptive and adaptive neuroplasticity mechanisms in anomia recovery. PMID:27429808

If AF is found, anticoagulation therapy provides a substantial decrease of the risk of recurrent cerebrovascular ischemic events. AF is often paroxysmal, and extensive diagnostic procedures may be necessary to detect it in patients. Considering cost-effectiveness and patient burden, however, not every suspected patient can be thoroughly screened. Therefore, the identification of risk factors for AF may be helpful. Previous studies have identified isolated aphasia as a risk factor for AF as the cause of the stroke. These studies, however, were performed with small population samples, in a retrospective setting or focused on a specific subtype of aphasia. The aim of this observational study is to prospectively evaluate whether there is a relation between isolated aphasia and AF as the cause of cerebrovascular ischemia. Methods: All patients admitted to the Atrium Medical Centre, Heerlen, the Netherlands, with cerebrovascular ischemia or transient ischemic attack in the period of August 2009 to March 2010 or October 2013 to January 2014 were included. The patients were evaluated by a neurologist and admitted to the Brain Care Unit for 24-48 h. Medical history, physical examination and diagnostic results were entered in a database. A diagnosis of isolated aphasia was assigned at admission using the National Institutes of Health Stroke Scale (NIHSS. Presence of AF was determined using a 12-lead electrocardiogram (ECG on admission and continuous ECG monitoring for 1-2 days. During admission, aphasia tests were done, notably the ScreeLing Test and the Boston Naming Test. Data were analyzed using Pearson's χ2 test, Fisher's exact test, the Mann-Whitney U test and univariate and multivariate logistic regression analyses. Results: A total of 347 patients were included, of which 115 (33.1% met the criteria for aphasia, with 26 (7.5% meeting the criteria

    Full Text Available Objective: To identify the scope and status of related research with the participation and social inclusion of adults with aphasia connected with the published literature. Materials and Methods: Descriptive analytic study on publications registered in Medline/PubMed, EBSCO and EMBASE from 2005 to 2013, 97 related documents were selected and classified into, eight common vari­ables for its study and were analyzed according to the article distribution by thematic core, year of publication and database. Results: The most represented core theme was inclusion, participa­tion, access and rights of persons with aphasia and their families and environments; production of these documents is increased between 2010 and 2011. Documents related to inclusive intern­ships for people with aphasia represented the second more representative thematic focus. Conclu­sions: Literature recognizes that elements related to family and their immediate environments are essential to ensure participation and independence of people with aphasia. The International Classification of Functioning, Disability and Health (ICF should become the rehabilitation log for professionals to guide therapeutic actions, aimed at the inclusion and participation of people with aphasia in different contexts, and mainly to promote a successful return to a productive daily life. This rehabilitation opportunity toward independence and autonomy promotes self-esteem, identity and inclusion opportunities.

  6. Degenerative Jargon Aphasia: Unusual Progression of Logopenic/Phonological Progressive Aphasia?

    2013-01-01

    Full Text Available Primary progressive aphasia (PPA corresponds to the gradual degeneration of language which can occur as nonfluent/agrammatic PPA, semantic variant PPA or logopenic variant PPA. We describe the clinical evolution of a patient with PPA presenting jargon aphasia as a late feature. At the onset of the disease (ten years ago the patient showed anomia and executive deficits, followed later on by phonemic paraphasias and neologisms, deficits in verbal short-term memory, naming, verbal and semantic fluency. At recent follow-up the patient developed an unintelligible jargon with both semantic and neologistic errors, as well as with severe deficit of comprehension which precluded any further neuropsychological assessment. Compared to healthy controls, FDG-PET showed a hypometabolism in the left angular and middle temporal gyri, precuneus, caudate, posterior cingulate, middle frontal gyrus, and bilaterally in the superior temporal and inferior frontal gyri. The clinical and neuroimaging profile seems to support the hypothesis that the patient developed a late feature of logopenic variant PPA characterized by jargonaphasia and associated with superior temporal and parietal dysfunction.

  7. FDG positron emission computed tomography in a study of aphasia

    International Nuclear Information System (INIS)

    Positron emission computed tomography (PECT) using 18F-2-fluoro-2-deoxy-D-glucose (FDG) was used to investigate the correlations between clinical status, anatomy (as described by CT), and metabolism in five patients with stable aphasia resulting from ischemic cerebral infarction. Local cerebral metabolic activity was diminished in an area larger than the area of infarction demonstrated by CT. In one patient, FDG PECT revealed a metabolic lesion that probably caused the aphasic syndrome and was not apparent by CT. The data suggest that reliance on CT in delineating the extent of the brain lesion in aphasia or other neuropsychological defects can be misleading; FDG PECT may provide important additional information. Two patients with similar metabolic lesions had very different clinical syndromes, showing that even when currently available methods are combined, major gaps remain in clinicoanatomical correlations in aphasia

    Full Text Available Howard S KirshnerDepartment of Neurology, Vanderbilt University Medical Center, Nashville, TN, USAAbstract: Frontotemporal dementias are neurodegenerative diseases in which symptoms of frontal and/or temporal lobe disease are the first signs of the illness, and as the diseases progress, they resemble a focal left hemisphere process such as stroke or traumatic brain injury, even more than a neurodegenerative disease. Over time, some patients develop a more generalized dementia. Four clinical subtypes characterize the predominant presentations of this illness: behavioral or frontal variant FTD, progressive nonfluent aphasia, semantic dementia, and logopenic primary progressive aphasia. These clinical variants correlate with regional patterns of atrophy on brain imaging studies such as MRI and PET scanning, as well as with biochemical and molecular genetic variants of the disorder. The treatment is as yet only symptomatic, but advances in molecular genetics promise new therapies.Keywords: FTD, behavior variant or frontal variant FTD, pick's disease, PPA, progressive nonfluent aphasia

    Word retrieval deficits for specific grammatical categories, such as verbs versus nouns, occur as a consequence of brain damage. Such deficits are informative about the nature of lexical organization in the human brain. This study examined retrieval of grammatical categories across three languages in a trilingual person with aphasia who spoke Arabic, French, and English. In order to delineate the nature of word production difficulty, comprehension was tested, and a variety of concomitant lexical-semantic variables were analysed. The patient demonstrated a consistent noun-verb dissociation in picture naming and narrative speech, with severely impaired production of verbs across all three languages. The cross-linguistically similar noun-verb dissociation, coupled with little evidence of semantic impairment, suggests that (a) the patient has a true "nonsemantic" grammatical category specific deficit, and (b) lexical organization in multilingual speakers shares grammatical class information between languages. The findings of this study contribute to our understanding of the architecture of lexical organization in bilinguals. PMID:20830631

    Full Text Available The aphasia is the most complicated and the most difficult form of disorder of speaking and language. Most often it appears as a consequence of a brain stroke. The occurrence of aphasias is in about one third of the patients suffering from a brain stroke in an acute phase, or from 21% to 24%, and there are data for even bigger frequency. In a certain number of patients the aphasia withdraws spontaneously, but in a bigger number of patients it takes over all four models of language activity; phoneme pronunciation, carrying out a discussion, writing a letter of a full text. It spreads from the automatic to the creative expression. The process of rehabilitation of the spoken communication at the persons with aphasia is complicated, multidisciplinary and long lasting.Around the World, a big accent is placed on the use of methods and strategies of alternative communication methods (AAK for the persons with aphasia. Although the augmentative and the AAK methods for the persons with aphasia are relatively novel in the speech therapy, their applicability deserves an attention as well as the fact that they are promising new paths for researching.The master thesis is written on 104 pages, which include 35 tables and 48 graphics, as well as a glossary with 114 biographical units. The content is divided into introduction, grounding theory and methodology of research. The introduction shows the meaning and the necessity for research of alternative methods in the therapy and the treatment of persons with aphasia. The section with the theoretical grounds contains several mutually connected chapters (parts. In methodology of research section are described the subject of the research, the aim and the character of the research.

    Individuals with aphasia demonstrated greater difficulties in the case marker assignment compared to their normal control group. Furthermore, noncanonical word-order and passive sentences elicited more errors on the task than canonical and active sentences. Passive sentences were the significant predictors for overall aphasia severity. The results suggested that PWA using a verb-final language with well-developed case-marking systems presented deficits in case marker processing. The syntactic structure and canonicity of word order need to be considered as critical linguistic features in testing their performance on dealing with case markers.

    Individuals with primary progressive aphasia (PPA) show selective breakdown in regions within the proposed dorsal (articulatory-phonological) and ventral (lexical-semantic) pathways involved in language processing. Phonological STM impairment, which has been attributed to selective damage to dorsal pathway structures, is considered to be a distinctive feature of the logopenic variant of PPA. By contrast, phonological abilities are considered to be relatively spared in the semantic variant and are largely unexplored in the nonfluent/agrammatic variant. Comprehensive assessment of phonological ability in the three variants of PPA has not been undertaken. We investigated phonological processing skills in a group of participants with PPA as well as healthy controls, with the goal of identifying whether patterns of performance support the dorsal versus ventral functional-anatomical framework and to discern whether phonological ability differs among PPA subtypes. We also explored the neural bases of phonological performance using voxel-based morphometry. Phonological performance was impaired in patients with damage to dorsal pathway structures (nonfluent/agrammatic and logopenic variants), with logopenic participants demonstrating particular difficulty on tasks involving nonwords. Binary logistic regression revealed that select phonological tasks predicted diagnostic group membership in the less fluent variants of PPA with a high degree of accuracy, particularly in conjunction with a motor speech measure. Brain-behavior correlations indicated a significant association between the integrity of gray matter in frontal and temporoparietal regions of the left hemisphere and phonological skill. Findings confirm the critical role of dorsal stream structures in phonological processing and demonstrate unique patterns of impaired phonological processing in logopenic and nonfluent/agrammatic variants of PPA.

    [Purpose] This study explored health science students’ perceptions of motor aphasia and sensory aphasia caused by stroke to provide basic material for the improvement of rehabilitation practitioners’ perceptions of aphasia. [Subjects and Methods] The subjects of this study were 642 freshmen and sophomores majoring in health science. Perceptions of aphasia were surveyed on a semantic differential scale using the Anchoring Vignette Method and the difference in perception of the two types of aphasia was analyzed using multi-dimensional scaling. [Results] The analysis revealed that motor aphasia and sensory aphasia have mutually corresponding images. Motor aphasia had high levels of ‘quiet’, ‘passive’ ‘dumb’, ‘unstable’ and ‘gloomy’ images, while sensory aphasia had high levels of ‘noisy’, ‘unstable’, ‘cheerful’, ‘sensitive’, ‘fluctuating in emotions’, ‘active’, ‘dumb’ and ‘gloomy’ images. [Conclusion] A systematic education is required to be implemented in the future to improve health science students’ negative perceptions of the aftereffects of stroke such as aphasia. PMID:27390413

    Full Text Available We report patterns of dysgraphia in participants with primary progressive aphasia that can be explained by assuming disruption of one or more cognitive processes or representations in the complex process of spelling. These patterns are compared to those described in participants with focal lesions (stroke. Using structural imaging techniques, we found that damage to the left extrasylvian regions, including the uncinate, inferior fronto-occipital fasciculus, and sagittal stratum (including geniculostriate pathway and inferior longitudinal fasciculus, as well as other deep white and grey matter structures, was significantly associated with impairments in access to orthographic word forms and semantics (with reliance on phonology-to-orthography to produce a plausible spelling in the spelling to dictation task. These results contribute not only to our understanding of the patterns of dysgraphia following acquired brain damage but also the neural substrates underlying spelling.

    Results: Neurologically-intact controls exhibited the standard inhibitory effect of phonological neighborhood density: faster responses to words from low-density than high-density phonological neighborhoods (Estimate = 103.05, SE = 42.05, p = 0.014. For participants with aphasia, the effect of phonological neighborhood density was larger for those with lower fluency (χ2(1 = 3.95, p = 0.047; Figure 1, left panel, but was not modulated by overall aphasia severity (χ2(1 = 1.64, p = 0.2. Receptive vocabulary size also modulated the neighborhood density effect (χ2(1 = 7.93, p = 0.005, which was larger in participants with aphasia who had larger receptive vocabularies (Figure 1, right panel. The correlation between WAB Fluency and PPVT scores was not significant (r = -0.325, p = 0.257, indicating that the opposite effects of fluency and receptive vocabulary were not the same underlying pattern. Conclusions: These results are consistent with the view that fluency deficits in aphasia are a consequence of difficulty selecting among completing candidates – both in comprehension and in production. Furthermore, the fact that vocabulary size and fluency had opposite effects on sensitivity to neighborhood density indicates that the effect of fluency is not an effect of lexicon size.

  5. Non-verbal communication in severe aphasia: influence of aphasia, apraxia, or semantic processing?

    Science.gov (United States)

    2012-09-01

    Patients suffering from severe aphasia have to rely on non-verbal means of communication to convey a message. However, to date it is not clear which patients are able to do so. Clinical experience indicates that some patients use non-verbal communication strategies like gesturing very efficiently whereas others fail to transmit semantic content by non-verbal means. Concerns have been expressed that limb apraxia would affect the production of communicative gestures. Research investigating if and how apraxia influences the production of communicative gestures, led to contradictory outcomes. The purpose of this study was to investigate the impact of limb apraxia on spontaneous gesturing. Further, linguistic and non-verbal semantic processing abilities were explored as potential factors that might influence non-verbal expression in aphasic patients. Twenty-four aphasic patients with highly limited verbal output were asked to retell short video-clips. The narrations were videotaped. Gestural communication was analyzed in two ways. In the first part of the study, we used a form-based approach. Physiological and kinetic aspects of hand movements were transcribed with a notation system for sign languages. We determined the formal diversity of the hand gestures as an indicator of potential richness of the transmitted information. In the second part of the study, comprehensibility of the patients' gestural communication was evaluated by naive raters. The raters were familiarized with the model video-clips and shown the recordings of the patients' retelling without sound. They were asked to indicate, for each narration, which story was being told and which aspects of the stories they recognized. The results indicate that non-verbal faculties are the most important prerequisites for the production of hand gestures. Whereas results on standardized aphasia testing did not correlate with any gestural indices, non-verbal semantic processing abilities predicted the formal diversity

  6. Crossed aphasia with jargonagraphia due to right putaminal hemorrhage

    International Nuclear Information System (INIS)

    The patient was a 47 year-old right handed male. He had been dextral since infancy with no familial background of sinistrality. On June 10, 1982 he suddenly developed hemiplegia, hemisensory disturbance on the left side and aphasia. On the same day he fell into a coma. CT scan revealed right putaminal hemorrhage. The patient was operated on to evacuate the hematoma. On October 25 he was admitted to our hospital, when left spastic hemiplegia, sensory deficit and left Babinski sign were noted. Neuropsychological examination showed fluent spontaneous speech but no dysprosodia. The result of Standard language test of aphasia were fairly good except for naming low frequency words. Repetition and auditory comprehension were normal. Dyslexia was not observed. Dyscaliculia was also observed. Idiomotor apraxia, ideational apraxia and dressing apraxia were not observed. This case is characterized by 1) fluent aphasia without agrammatism, and 2) jargonagraphia. Fluent aphasia in a right-hander is said to be caused by a left postrolandic lesion. Lesions judged by computed tomography were located from the right putamen to the corona radiata. Single photon emission CT (SPECT) was performed with the 133Xe inhalation method. SPECT revealed a low blood flow area in the basal ganglia, a branch of the right anterior cerebral and of the middle cerebral artery. Furthermore the low blood flow area extended to the post-central gyrus of the right cerebrum. No obvious low blood flow area was seen in the left hemisphere. The most difficult problem for clinical diagnosis of crossed aphasia is whether the lesion is localized solely in the right hemisphere or not. SPECT is very helpful for detecting lesions not revealed by CT. (J.P.N.)

    Full Text Available Achieved children speech disabilities are manifested at certain level of development of speech from the age of 3 to 12 years. The speech disabilities with children from the age of one to three years have developmental and acquired characteristics. It is well-known when and why the disabilities occurr at acquired aphasia or disphasia.The child with acquired aphasia or disphasia has early brain impairements and a relative improvement happens with adequate treatment and prompt rehabilitation treatment. It is more obvious with children than with adults.This fast and complete rehabilitation happens due to the plastic character of child’s brain and the possibilities for intro-hemisphere and inter-hemisphere reorganization of speech functions in childhood.

    1985-09-01

    A 47-year-old man with a left temporo-occipital infarct in the area of the posterior cerebral artery is presented. The neuropsychological examination did not reveal aphasia or gross mental deficits. The patient presented with alexia without agraphia, color agnosia, but few visual perceptual deficits. The main impairment was in confrontation naming; he was incapable of naming objects and pictures, not from lack of recognition (excluding visual agnosia) but from lack of access to the appropriate word (optic aphasia). The patient also exhibited a deficit in the evocation of gesture from the visual presentation of an object (optic apraxia) and a difficulty in "conjuring up" visual images of objects (impaired visual imagery) and loss of dreams. The fundamental deficit of this patient is tentatively explained in terms of visuoverbal and visuogestural disconnection and a deficit of mental imagery. PMID:2413956

  12. Web based aphasia test using service oriented architecture (SOA)

    International Nuclear Information System (INIS)

    Based on an aphasia test for Spanish speakers which analyze the patient's basic resources of verbal communication, a web-enabled software was developed to automate its execution. A clinical database was designed as a complement, in order to evaluate the antecedents (risk factors, pharmacological and medical backgrounds, neurological or psychiatric symptoms, brain injury -anatomical and physiological characteristics, etc) which are necessary to carry out a multi-factor statistical analysis in different samples of patients. The automated test was developed following service oriented architecture and implemented in a web site which contains a tests suite, which would allow both integrating the aphasia test with other neuropsychological instruments and increasing the available site information for scientific research. The test design, the database and the study of its psychometric properties (validity, reliability and objectivity) were made in conjunction with neuropsychological researchers, who participate actively in the software design, based on the patients or other subjects of investigation feedback

    Vigliecca, Nora Silvana; Báez, Sandra

    2015-12-01

    A theoretical framework which considers the verbal functions of the brain under a multivariate and comprehensive cognitive model was statistically analyzed. A confirmatory factor analysis was performed to verify whether some recognized aphasia constructs can be hierarchically integrated as latent factors from a homogenously verbal test. The Brief Aphasia Evaluation was used. A sample of 65 patients with left cerebral lesions, and two supplementary samples comprising 35 patients with right cerebral lesions and 30 healthy participants were studied. A model encompassing an all inclusive verbal organizer and two successive organizers was validated. The two last organizers were: three factors of comprehension, expression and a "complementary" verbal factor which included praxia, attention, and memory; followed by the individual (and correlated) factors of auditory comprehension, repetition, naming, speech, reading, writing, and the "complementary" factor. By following this approach all the patients fall inside the classification system; consequently, theoretical improvement is guaranteed. PMID:25168953

  14. A study of conduction aphasia by positron emission tomography

    International Nuclear Information System (INIS)

    We reported two cases of conduction aphasia with distinctive language disorder from early stage of stroke, as well as their cerebral blood flow and oxygen consumption investigated with PET. The case was a 72-year-old right handed man whose speech disturbance began acutely. On admission, neurological examination revealed hand pronation sign on the right and speech disturbance. Other neurological findings including cortical functions were normal. Brain CT scan showed low density area in the white matter of the left supramarginal gyrus. The diagnosis was cerebral infarction. The case 2 was a 64-year-old right handed man. He suffered right hemiparesis 2 months before. Neurological examination revealed mild right hemiparesis and speech disturbance. Other cortical functions were noncontributory. Brain CT scan showed old subcortical infarction of the left frontal lobe and new cerebral infarction. with supramarginal gyrus. The low density area of the supramarginal cortex extended into the subcortical white matter. The language performances in these two cases were similar. Two patients were definitely fluent, but the verbal output was contaminated by paraphasias which were predominantly literal. They performed poorly when attempting to repeat despite good comprehension. Thus, the primary characteristics of conduction aphasia were present. PET studies resulted as follows. 1) rCBF reduced 36 % in the supramarginal cortex, 50 % in the white matter. 2) rCMRO2 reduced 37 % in the supramarginal cortex, 45 % in the white matter. 3) The CBF and the CMRO2 images indicated that cerebral blood flow and oxygen consumption reduced in wider range of area than that shown by brain CT. These results indicated that not only the cortex but also the white matter were damaged in conduction aphasia and several methods including PET should be used to determine the locus of abnormality in conduction aphasia.

    We reported two cases of conduction aphasia with distinctive language disorder from early stage of stroke, as well as their cerebral blood flow and oxygen consumption investigated with PET. The case was a 72-year-old right handed man whose speech disturbance began acutely. On admission, neurological examination revealed hand pronation sign on the right and speech disturbance. Other neurological findings including cortical functions were normal. Brain CT scan showed low density area in the white matter of the left supramarginal gyrus. The diagnosis was cerebral infarction. The case 2 was a 64-year-old right handed man. He suffered right hemiparesis 2 months before. Neurological examination revealed mild right hemiparesis and speech disturbance. Other cortical functions were noncontributory. Brain CT scan showed old subcortical infarction of the left frontal lobe and new cerebral infarction. with supramarginal gyrus.

    Full Text Available Background and purposes: Anomic aphasia is common in patients with left hemispheric strokes. The purpose of this study was to explore the verbal production of ischemic stroke patients with anomic aphasia. Contingent and methods: Fifty ischemic stroke patients admitted to the Neurology Clinic of University Hospital Pleven were studied by neuropsychological battery and CT scan of the brain. Verbal productivity changes found were analyzed in relation to the speech recovery education. Results: All the patients showed lower scores at all nominative and reproductive speech subtests. Discussion: Among the ischemic stroke patients with mild anomic aphasia comparatively great was the percentage of low frequency word actualization and verbal fluency impairment. The usage of nominatives in speech expression of ischemic stroke patients is less as compared with that one of predicatives. Actualization of particles, unions, prepositions and interjections was comparatively high thus compensating the difficulty in choice of a definite lexical number. Conclusion: Future studies on testing of verbal choice in ischemic stroke patients should confirm its practical significance for the assessment of speech disorders concerning a special speech- recovery education.

  1. Symptoms of aphasia and lesions in the brain

    International Nuclear Information System (INIS)

    Sixty-nine cases with a variety of types of aphasia were studied to determine the relationship between the locus and extent of the lesion, as demonstrated by cranial tomography, and the speech and language function of the patients, as evaluated by the Comprehensive Examination of Aphasia (CEA, the latest revised version of the Schuell-Sasanuma Diagnosis Test of Aphasia). The figure of the lateral view of the brain illustrating the lesion site was made from the horizontal tomogram for each patient. The figures thus obtained for all the patients in each subtest of ECA were processed by the following two methods: (1) a superimposed illustration showing only the patients whose test scores were smaller than the average and (2) an illustration showing the distribution of the average test scores on the lateral view of the brain. The results were summarized as follows: 1. Of 14 speech and language tests, the performance in the 6 areas listed below was exclusively related to the frontal lobe: description of pictured situation phonemic paraphasia fluency imitating examiner; palatal movements rapid repetition of monosyllables rapid repetition of three-syllables (e.g., pa-ta-ka) 2. Concerning the speech areas in the frontal lobe, they were distributed throughout instead of being limited to Broca's area. 3. It became clear that the performance in all the areas except those mentioned above had a close connection with the parietal, temporal, and occipital lobes, while, at the same time, partly involving the frontal lobe.

  14. How to engage the right brain hemisphere in aphasics without even singing: evidence for two paths of speech recovery

    Directory of Open Access Journals (Sweden)

    Benjamin eStahl

    2013-02-01

    Full Text Available There is an ongoing debate as to whether singing helps left-hemispheric stroke patients recover from non-fluent aphasia through stimulation of the right hemisphere. According to recent work, it may not be singing itself that aids speech production in non-fluent aphasic patients, but rhythm and lyric type. However, the long-term effects of melody and rhythm on speech recovery are largely unknown. In the current experiment, we tested 15 patients with chronic non-fluent aphasia who underwent either singing therapy, rhythmic therapy, or standard speech therapy. The experiment controlled for phonatory quality, vocal frequency variability, pitch accuracy, syllable duration, phonetic complexity and other influences, such as the acoustic setting and learning effects induced by the testing itself. The results provide the first evidence that singing and rhythmic speech may be similarly effective in the treatment of non-fluent aphasia. This finding may challenge the view that singing causes a transfer of language function from the left to the right hemisphere. Instead, both singing and rhythmic therapy patients made good progress in the production of common, formulaic phrases—known to be supported by right corticostriatal brain areas. This progress occurred at an early stage of both therapies and was stable over time. Conversely, patients receiving standard therapy made less progress in the production of formulaic phrases. They did, however, improve their production of non-formulaic speech, in contrast to singing and rhythmic therapy patients, who did not. In light of these results, it may be worth considering the combined use of standard therapy and the training of formulaic phrases, whether sung or rhythmically spoken. Standard therapy may engage, in particular, left perilesional brain regions, while training of formulaic phrases may open new ways of tapping into right-hemisphere language resources—even without singing.

  15. Transcortical Motor Aphasia in Recovery: A Case Report

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Introduction The symptomatology of transcortical motor aphasia (TMA or dynamic aphasia (Luria & Tsvetkova, 1970 allows the clinician to investigate “the particularly interesting stage in transition from initial thought to final verbal expression” and “to study in pure form the lack of speech initiative” (Rubens, 1976,p. 302. The symptoms described in the literature include: difficulty initiating speech, limited spontaneous speech, intact repetition, good auditory comprehension. In contrast, agrammatic sentence production is associated with Broca’s aphasia. Language data from a participant presenting with TMA and also agrammatic symptoms who showed a good recovery are analyzed. The aim of this presentation is to tease apart the observed language features to arrive at a better understanding of the nature of specific symptoms and their impact on language processing. Methods Participant GS: a 17-year-old carpenter’s apprentice, suffered a massive stroke. A complete occlusion of the left anterior-cerebral-artery was diagnosed. Procedure From 4 weeks to 10 months post onset GS was administered standardized language tests and tasks covering all linguistic levels. A matched control person (MH was also tested. Results Selected results and examples are given in Table 1. GS’s initiation of spontaneously produced speech is captured by his slow rate of production and verbal output for texts in comparison to control MH. As shown in Table 1, specific syntactic features showed impairment. At six months his aphasia had evolved into a mild impairment. Discussion The utterances produced by a classical TMA patient are usually grammatical. In part, this applies to G.S. However, he also reveals the following difficulties: simplification of syntactic structure, substitutions and omissions of articles, frequent omission of prepositions, verb agreement and selection errors, and reversal of subject and object noun phrases various sentence and discourse

    2014-01-01

    Global aphasia without hemiparesis is a striking stroke syndrome involving language impairment without the typically manifested contralateral hemiparesis, which is usually seen in patients with global aphasia following large left perisylvian lesions. The objective of this study is to elucidate the speciifc areas for lesion localization of global aphasia without hemiparesis by retrospectively studying the brain magnetic resonance images of six patients with global aphasia without hemi-paresis to deifne global aphasia without hemiparesis-related stroke lesions before overlapping the images to visualize the most overlapped area. Talairach coordinates for the most overlapped areas were converted to corresponding anatomical regions. Lesions where the images of more than three patients overlapped were considered significant. The overlapped global aphasia without hemiparesis related stroke lesions of six patients revealed that the signiifcantly involved anatomi-cal lesions were as follows:frontal lobe, sub-gyral, sub-lobar, extra-nuclear, corpus callosum, and inferior frontal gyrus, while caudate, claustrum, middle frontal gyrus, limbic lobe, temporal lobe, superior temporal gyrus, uncus, anterior cingulate, parahippocampal, amygdala, and subcallosal gyrus were seen less signiifcantly involved. This study is the ifrst to demonstrate the heteroge-neous anatomical involvement in global aphasia without hemiparesis by overlapping of the brain magnetic resonance images.

    Thompson, Cynthia K; Cho, Soojin; Hsu, Chien-Ju; Wieneke, Christina; Rademaker, Alfred; Weitner, Bing Bing; Mesulam, M-Marsel; Weintraub, Sandra

    2012-01-01

    BACKGROUND: Classical aphasiology, based on the study of stroke sequelae, fuses speech fluency and grammatical ability. Nonfluent (Broca's) aphasia often is accompanied by agrammatism; whereas in the fluent aphasias grammatical deficits are not typical. The assumption that a similar relationship exists in primary progressive aphasia (PPA) has led to the dichotomization of this syndrome into fluent and nonfluent subtypes. AIMS: This study compared elements of fluency and grammatical production in the narrative speech of individuals with PPA to determine if they can be dissociated from one another. METHOD: Speech samples from 37 individuals with PPA, clinically assigned to agrammatic (N=11), logopenic (N=20) and semantic (N=6) subtypes, and 13 cognitively healthy control participants telling the "Cinderella Story" were analyzed for fluency (i.e., words per minute (WPM) and mean length of utterance in words (MLU-W)) and grammaticality (i.e., the proportion of grammatically correct sentences, open-to-closed-class word ratio, noun-to-verb ratio, and correct production of verb inflection, noun morphology, and verb argument structure.) Between group differences were analyzed for each variable. Correlational analyses examined the relation between WPM and each grammatical variable, and an off-line measure of sentence production. OUTCOMES AND RESULTS: Agrammatic and logopenic groups both had lower scores on the fluency measures and produced significantly fewer grammatical sentences than did semantic and control groups. However, only the agrammatic group evinced significantly impaired production of verb inflection and verb argument structure. In addition, some semantic participants showed abnormal open-to-closed and noun-to-verb ratios in narrative speech. When the sample was divided on the basis of fluency, all the agrammatic participants fell in the nonfluent category. The logopenic participants varied in fluency but those with low fluency showed variable performance on

  20. Action observation as a tool for neurorehabilitation to moderate motor deficits and aphasia following stroke

    Institute of Scientific and Technical Information of China (English)

    Denis Ertelt; Ferdinand Binkofski

    2012-01-01

    The mirror neuron system consists of a set of brain areas capable of matching action observation with action execution. One core feature of the mirror neuron system is the activation of motor areas by action observation alone. This unique capacity of the mirror neuron system to match action perception and action execution stimulated the idea that mirror neuron system plays a crucial role in the understanding of the content of observed actions and may participate in procedural learning. These features bear a high potential for neurorehabilitation of motor deficits and of aphasia following stroke. Since the first articles exploring this principle were published, a growing number of follow-up studies have been conducted in the last decade. Though, the combination of action observation with practice of the observed actions seems to constitute the most powerful approach. In the present review, we present the existing studies analyzing the effects of this neurorehabilitative approach in clinical settings especially in the rehabilitation of stroke associated motor deficits and give a perspective on the ongoing trials by our research group. The data obtained up to date showed significant positive effect of action observation on recovery of motor functions of the upper limbs even in the chronic state after stroke, indicating that our approach might become a new standardized add-on feature of modern neurorehabilitative treatment schemes.

    Introduction Aphasia is a language disorder resulting from a lesion in the cerebral cortex. In this case report, we present a polyglot patient who recovered from aphasia by speaking his newly active learned language Case Report A 69 years old male referred with acute onset right hemiparesis and global aphasia. After imaging, he treated with 75 mg r-TPA (0.9 mg/kg). After the fourth day of hospitalization, he could name some objects and some short phrases but interestingly only in French language (although his mother language was Persian). Discussion In our patient, recovery was first in the last learned language and his learning memory was recovered earlier than his native languages. As in our case, we can expect to have different recovery theory that means active learning language could be the first part of recovery in aphasia. PMID:25337377

    Treatment intensity is a critical component to the delivery of speech-language pathology and rehabilitation services. Within aphasia rehabilitation, however, insufficient evidence currently exists to guide clinical decision making with respect to the optimal treatment intensity. This review considers perspectives from 2 key bodies of research, the neuroscience and cognitive psychology literature, with respect to the scheduling of aphasia rehabilitation services. Neuroscience research suggests that intensive training is a key element of rehabilitation and is necessary to achieve functional and neurologic changes after a stroke occurs. In contrast, the cognitive psychology literature suggests that optimal long-term learning is achieved when training is provided in a distributed or nonintensive schedule. These perspectives are evaluated and discussed with respect to the current evidence for treatment intensity in aphasia rehabilitation. In addition, directions for future research are identified, including study design, methods of defining and measuring treatment intensity, and selection of outcome measures in aphasia rehabilitation.

    Full Text Available Melodic intonation therapy (MIT is a structured protocol for language rehabilitation in people with Broca’s aphasia. The main particularity of MIT is the use of intoned-speech, a technique in which the clinician stylizes the prosody of short sentences using simple pitch and rhythm patterns. In the original MIT protocol, patients must repeat diverse sentences in order to espouse this way of speaking, with the goal of improving their natural, connected speech. MIT has long been regarded as a promising treatment but its mechanisms are still debated. Recent work showed that rhythm plays a key role in variations of MIT, leading to consider the use of pitch as relatively unnecessary in MIT. Our study primarily aimed to prospectively assess the relative contribution of rhythm and pitch in MIT’s generalization effect to non-trained stimuli and to connected speech. We compared a melodic therapy (with pitch and rhythm with a rhythmic therapy (with rhythm only and with a normally spoken therapy (without melodic elements. Three participants with chronic post-stroke Broca’s aphasia underwent the treatments in hourly sessions three days a week for six weeks, in a cross-over design. The informativeness of connected speech, speech accuracy of trained and non-trained sentences, motor-speech agility and mood was assessed before and after the treatments. The results show that the three treatments improved speech accuracy in trained sentences, but that the combination of rhythm and pitch elicited the strongest generalization effect both to non-trained stimuli and connected speech. No significant change was measured in motor-speech agility or mood measures, with neither treatment. The results emphasize the beneficial effect of both rhythm and pitch in the efficacy of original MIT on connected speech, an outcome of primary clinical importance in aphasia therapy.

    Introduction It is important to understand crosslinguistic differences in language impairment in aphasia, given that aphasia symptoms may vary depending on the linguistic characteristics of the language that individuals with aphasia used premorbidly (Bates & Wulfeck, 1989). Language-specific symptoms need to be considered for evaluating language impairment in aphasia. Korean, as a verb-final language, follows a canonical word order of Subject-Object-Verb (SOV), whereas a canonical word ord...

    BACKGROUND: It is thought in disconnection theory that connection of anterior and posterior language function areas, i.e. the lesion of arcuate fasciculus causes conduction aphasia.OBJECTIVE: To verify the theory of disconnection elicited by repetition disorder in patients with conduction aphasia by comparing the characteristics of diffusion tensor imaging between healthy persons and patients with conduction aphasia.DESIGN: Case-control observation.SETTING: Department of Neurology, Hongqi Hospital Affiliated to Mudanjiang Medical College.PARTICIPANTS: Five male patients with cerebral infarction-involved arcuate fasciculus conduction aphasia, averaged (43±2) years, who hospitalized in the Department of Neurology, Hongqi Hospital Affiliated to Mudanjiang Medical College from February 2004 to February 2005 were involved in this experiment. The involved patients were all confirmed as cerebral infarction by skull CT and MRI, and met the diagnosis criteria revised in 1995 4th Cerebrovascular Conference. They were examined by the method of Aphasia Battery of Chinese (ABC) edited by Surong Gao. The results were poorer than auditory comprehension disproportionately, and consistented with the mode of conduction aphasia. Another 5 male healthy persons, averaged (43 ± 1 ) years, who were physicians receiving further training in the Department of Neurology, Beijing Tiantan Hospital were also involved in this experiment. Informed consents of detected items were obtained from all the subjects.METHODS: All the subjects were performed handedness assessment with assessment criteria of handedness formulated by Department of Neurology, First Hospital Affiliated to Beijing Medical University. Arcuate fasciculus of involved patients and health controls were analyzed with diffusion tensor imaging (DTI) and divided into 3 parts (anterior, middle and posterior segments) for determining FA value (mean value was obtained after three times of measurements), and a comparison of FA value was

  18. Frontal dynamic aphasia in progressive supranuclear palsy: Distinguishing between generation and fluent sequencing of novel thoughts.

    2015-10-01

    Frontal dynamic aphasia is characterised by a profound reduction in spontaneous speech despite well-preserved naming, repetition and comprehension. Since Luria (1966, 1970) designated this term, two main forms of dynamic aphasia have been identified: one, a language-specific selection deficit at the level of word/sentence generation, associated with left inferior frontal lesions; and two, a domain-general impairment in generating multiple responses or connected speech, associated with more extensive bilateral frontal and/or frontostriatal damage. Both forms of dynamic aphasia have been interpreted as arising due to disturbances in early prelinguistic conceptual preparation mechanisms that are critical for language production. We investigate language-specific and domain-general accounts of dynamic aphasia and address two issues: one, whether deficits in multiple conceptual preparation mechanisms can co-occur; and two, the contribution of broader cognitive processes such as energization, the ability to initiate and sustain response generation over time, to language generation failure. Thus, we report patient WAL who presented with frontal dynamic aphasia in the context of progressive supranuclear palsy (PSP). WAL was given a series of experimental tests that showed that his dynamic aphasia was not underpinned by a language-specific deficit in selection or in microplanning. By contrast, WAL presented with a domain-general deficit in fluent sequencing of novel thoughts. The latter replicated the pattern documented in a previous PSP patient (Robinson, et al., 2006); however, unique to WAL, generating novel thoughts was impaired but there was no evidence of a sequencing deficit because perseveration was absent. Thus, WAL is the first unequivocal case to show a distinction between novel thought generation and subsequent fluent sequencing. Moreover, WAL's generation deficit encompassed verbal and non-verbal responses, showing a similar (but more profoundly reduced) pattern

    Some individuals with aphasia preferably use semantically general light verbs, whereas others prefer semantically specific heavy verbs. This study aimed to test Gordon and Dell's "division of labor" hypothesis that light versus heavy verb usage depends on syntactic and semantic processes, respectively. In a retrospective analysis of data from the AphasiaBank corpus, narrative language of neurologically healthy individuals and individuals with aphasia was analyzed for the proportion of light verbs used, and its relationship with narrative measures of syntactic and semantic sophistication and verb naming scores was examined. In individuals with aphasia, light verb usage was positively correlated with a syntactic measure (developmental sentence score) and negatively associated with two semantic measures (idea density and verb naming). For healthy individuals, the number of verbs per utterance, which is a measure of syntactic complexity, predicted light verb use. These findings suggest that light verb usage in aphasia observes an inverse relationship with syntactic and semantic abilities, supporting the division of labor hypothesis. PMID:26882362

    Full Text Available Little is known about the neural mechanisms by which transcranial direct current stimulation (tDCS impacts on language processing in post-stroke aphasia. This was addressed in a proof-of-principle study that explored the effects of tDCS application in aphasia during simultaneous functional magnetic resonance imaging (fMRI. We employed a single subject, cross-over, sham-tDCS controlled design and the stimulation was administered to an individualized perilesional stimulation site that was identified by a baseline fMRI scan and a picture naming task. Peak activity during the baseline scan was located in the spared left inferior frontal gyrus (IFG and this area was stimulated during a subsequent cross-over phase. tDCS was successfully administered to the target region and anodal- vs. sham-tDCS resulted in selectively increased activity at the stimulation site. Our results thus demonstrate that it is feasible to precisely target an individualized stimulation site in aphasia patients during simultaneous fMRI which allows assessing the neural mechanisms underlying tDCS application. The functional imaging results of this case report highlight one possible mechanism that may have contributed to beneficial behavioural stimulation effects in previous clinical tDCS trials in aphasia. In the future, this approach will allow identifying distinct patterns of stimulation effects on neural processing in larger cohorts of patients. This may ultimately yield information about the variability of tDCS-effects on brain functions in aphasia.

    Reported speech, wherein one quotes or paraphrases the speech of another, has been studied extensively as a set of linguistic and discourse practices. Researchers agree that reported speech is pervasive, found across languages, and used in diverse contexts. However, to date, there have been no studies of the use of reported speech among individuals with aphasia. Grounded in an interactional sociolinguistic perspective, the study presented here documents and analyzes the use of reported speech by 7 adults with mild to moderately severe aphasia and their routine communication partners. Each of the 7 pairs was videotaped in 4 everyday activities at home or around the community, yielding over 27 hr of conversational interaction for analysis. A coding scheme was developed that identified 5 types of explicitly marked reported speech: direct, indirect, projected, indexed, and undecided. Analysis of the data documented reported speech as a common discourse practice used successfully by the individuals with aphasia and their communication partners. All participants produced reported speech at least once, and across all observations the target pairs produced 400 reported speech episodes (RSEs), 149 by individuals with aphasia and 251 by their communication partners. For all participants, direct and indirect forms were the most prevalent (70% of RSEs). Situated discourse analysis of specific episodes of reported speech used by 3 of the pairs provides detailed portraits of the diverse interactional, referential, social, and discourse functions of reported speech and explores ways that the pairs used reported speech to successfully frame talk despite their ongoing management of aphasia.

    Full Text Available Lesions to Broca’s area cause aphasia characterised by a severe impairment of the ability to speak, with comparatively intact speech perception. However, some studies have found effects on speech perception under adverse listening conditions, indicating that Broca’s area is also involved in speech perception. While these studies have focused on auditory speech perception other studies have shown that Broca’s area is activated by visual speech perception. Furthermore, one preliminary report found that a patient with Broca’s aphasia did not experience the McGurk illusion suggesting that an intact Broca’s area is necessary for audiovisual integration of speech. Here we describe a patient with Broca’s aphasia who experienced the McGurk illusion. This indicates that an intact Broca’s area is not necessary for audiovisual integration of speech. The McGurk illusions this patient experienced were atypical, which could be due to Broca’s area having a more subtle role in audiovisual integration of speech. The McGurk illusions of a control subject with Wernicke’s aphasia were, however, also atypical. This indicates that the atypical McGurk illusions were due to deficits in speech processing that are not specific to Broca’s aphasia.

  3. 99mTc-ECD SPECT study in dementia and aphasia

    International Nuclear Information System (INIS)

    We studied clinical significance of 99mTc-L,L,-ethyl cysteine dimer (99mTc-ECD) SPECT study in dementia and aphasia, and compared it with 99mTc-HMPAO SPECT study. The subjects consisted of 13 patients, including 10 patients with dementia and 3 patients with aphasia. Hypoperfusion areas were detected in 5 out of 10 patients with dementia and 2 out of 3 patients with aphasia in 99mTc-ECD SPECT, and in 4 out of 10 patients with dementia and all of 3 patients with aphasia in 99mTc-HMPAO SPECT. The count rate ratios in 99mTc-ECD and 99mTc-HMPAO SPECT were correlated well with each other, and the contrast of the 99mTc-ECD SPECT image was equivalent or slightly higher as compared with 99mTc-HMPAO. Therefore, 99mTc-ECD SPECT study was considered to be useful for the evaluation of cerebral perfusion in dementia and aphasia. (author)

    Full Text Available Aphasia is a common manifestation of Creutzfeldt-Jakob disease (CJD, and investigation of the linguistic disorders of CJD patients may provide insights into the neurobiological mechanisms of language and aphasia. We report an autopsy-confirmed case of CJD in which the presenting symptom was change in language abilities. The patient ultimately evidenced mixed transcortical aphasia (MTA with echolalia. Disruption of frontal-subcortical circuits with environmental dependency accounts for the symptoms in MTA, including intact repetition and echolalia. Observation in this patient and a review of the literature suggest that frontal-subcortical circuit dysfunction may contribute to the syndrome of echolalia. This hypothesis offers an alternative explanation to “isolation” of the speech area as the cause of MTA.

  5. Variations in the presentation of aphasia in patients with closed head injuries.

    Impairments of speech and language are important consequences of head injury as they compromise interaction between the patient and others. A large spectrum of communication deficits can occur. There are few reports in the literature of aphasia following closed head injury despite the common presentation of closed head injury. Herein we report two cases of closed head injuries with differing forms of aphasia. We discuss their management and rehabilitation and present a detailed literature review on the topic. In a busy acute surgical unit one can dismiss aphasia following head injury as behaviour related to intoxication. Early recognition with prolonged and intensive speech and language rehabilitation therapy yields a favourable outcome as highlighted in our experience. These may serve as a reference for clinicians faced with this unusual outcome.

    1991-10-01

    Two cases of aphasia in polyglot patients who experienced different symptoms in each of the languages they knew are reported. The authors discuss the problem and analyze the available literature in an attempt to formulate a pathogenetic hypothesis of the different involvement of the known idioms sometimes observed in aphasic polyglots. In particular, when time has elapsed between the learning of the mother tongue and other languages, and all the known languages are, consequently, functionally independent, it is possible that the two or more known idioms have distinct anatomical representations, probably localized separately in the two hemispheres. This could explain why, in some polyglots, aphasia affects one of the known languages preferentially. In subjects in whom the different known idioms were learned during early childhood, the anatomical representation of the languages is similar, which explains why, in this kind of polyglot, all the known languages can be equally affected by cerebral damage that causes aphasia.

  7. Bilingualism and memory: early 19th century ideas about the significance of polyglot aphasia.

    2007-07-01

    In the second half of the 19th century, there was very little attention given to bilingual speakers within the growing clinical literature on aphasia. The first major publication on this topic (Pitres, 1895), appeared three decades after Broca's seminal work. Previously, Ribot (1881) had discussed the phenomenon of bilingual aphasia in the context of diseases of memory. Although interest in the neurological basis of the language faculty was in fact present throughout the century, the theoretical implications of the knowledge of more than one language did not appear to be linked to this issue. A number of British authors writing in the first half of the 19th century have been identified who did consider the significance of these cases. Importantly, these writers speculated on the implication of bilingual aphasia specifically with regard to ideas about memory rather than language. Consideration of these writings helps to illuminate the history of ideas about the organization of language in the brain. PMID:17715800

    Full Text Available Telepractice involves the application of technology to deliver services over a geographical distance. Studies in which telepractice procedures were used in the assessment or treatment of individuals with aphasia were reviewed. Systematic searches identified 10 studies meeting inclusion criteria. These studies were evaluated in terms of the: (a characteristics of the participants, (b technology utilized (c, services delivered via telepractice (d, research methodology, and (e results and conclusions of the study. Telepractice was used by speech-language pathologists and the allied health professionals to assist with the delivery of services to participants with aphasia by their caretakers or clinicians. The services delivered included appraisal, diagnostic assessments, interventions, and consultation. This review suggests that telepractice is a viable method of service delivery for individuals with aphasia and warrants additional research. Guidelines for practitioners and potential directions for future research are discussed.

    2011-09-01

    Management of patients with aph asia often focuses on training nonverbal augmentative communication strategies; however, these strategies frequently do not generalize to natural situations. The limited success may be because training waS not sufficient to produce an integrated multimodal semantic representation. The purpose of this study was to examine whether simultaneous training of stimuli in both verbal and nonverbal modalities would solidify the links within the semantic network and improve switching among modalities as needed in conversation. Two individuals with severe aphasia participated in 6 to 8 hours of Multi moda I Communication Training (MeT), during which they conveyed a concept by verbalizing, gesturing, writing, and drawing. After practice with all modalities for a single concept, a new concept was introduced. Results showed that one participant increased conveyance of concepts on the functional communication task using a variety of modalities. Although some improvement was seen with the second participant, his overall performance remained poor, likely because of a greater impairment in semantic knowledge. After a brief period of semantic training, the second participant demonstrated additional gains. Thus, MeT may serve to increase switching among verbal and nonverbal modalities in individuals with intact semantic representations, thereby increasing the likelihood that individuals will use an alternative method to communicate.

    Full Text Available Objective: this study compares the performance of two groups of participants with and without aphasia anomic in a lexical decision tasks (LDT and spelling, in relation to the effect of the variables of word frequency and syllable. Materials and methods: a prospective study with a 2x2x2 design, which administered the LDT, in which each she/he had to decide if it was a real Spanish word or not, pressing one of two keys. To the task of spelling, they had to spell orally each of words presented auditorily. Results: It was found that in the LTD, the experimental group made more errors in the high-frequency stimuli syllable while the control group had more errors in the low-frequency syllables. In terms of reaction times was evident that the experimental group took longer to solve the task than the control group. The spelling task performance showed no difference in groups or conditions (lexical frequency and syllable. Conclusions: similar than other researches in normalized population, the results of this study demonstrate the effect of lexical frequency facilitation and inhibition that generates high syllable frequency.

    We aimed to explore the nature of verbal repetition deficits and infer the cognitive systems involved in primary progressive aphasia (PPA) and Alzheimer's disease (AD). A total of 63 patients (13 semantic variant (sv-PPA), 17 nonfluent/agrammatic variant (nfv-PPA), 10 logopenic variant (lv-PPA), 23 AD) and 13 matched healthy controls completed a battery of tests that included naming, word comprehension, digit span, repetition of multisyllabic single words, monosyllabic word span presented under similar and dissimilar phonological conditions, and sentence repetition. All patient groups displayed some level of impairment, however, specific patterns emerged in each variant. Participants with sv-PPA were the least impaired, showing marginal difficulties exclusively for sentence repetition, whereas those with lv-PPA had the worst overall performance. Cases with nfv-PPA showed compromised repetition of multisyllabic and phonologically similar words. The deficit in cases with AD was confined to span tasks. These distinctive patterns of language impairments can assist in the differential diagnosis of PPA variants and point toward the vulnerability of specific cognitive systems in each syndrome.

    2015-04-01

    Data collected to date demonstrate a clear difference between individuals with and without aphasia in their ability to perceive masked real words, but there appears to be no difference between groups for non-words and non-linguistic stimuli, although a trend is seen for these groups. Given the high variability for the NW and NL conditions, these analyses may be underpowered; therefore, data collection is ongoing and a clearer picture should be available by the time of presentation. Regardless of the eventual outcome, this poster will discuss the theoretical motivation for the study, and will discuss the possible implications for understanding the nature of underlying deficits in aphasia.

    2015-02-01

    Emergence of visual and musical creativity in the setting of neurologic disease has been reported in patients with semantic variant primary progressive aphasia (svPPA), also called semantic dementia (SD). It is hypothesized that loss of left anterior frontotemporal function facilitates activity of the right posterior hemispheric structures, leading to de novo creativity observed in visual artistic representation. We describe creativity in the verbal domain, for the first time, in three patients with svPPA. Clinical presentations are carefully described in three svPPA patients exhibiting verbal creativity, including neuropsychology, neurologic exam, and structural magnetic resonance imaging (MRI). Voxel-based morphometry (VBM) was performed to quantify brain atrophy patterns in these patients against age-matched healthy controls. All three patients displayed new-onset creative writing behavior and produced extensive original work during the course of disease. Patient A developed interest in wordplay and generated a large volume of poetry. Patient B became fascinated with rhyming and punning. Patient C wrote and published a lifestyle guidebook. An overlap of their structural MR scans showed uniform sparing in the lateral portions of the language-dominant temporal lobe (superior and middle gyri) and atrophy in the medial temporal cortex (amygdala, limbic cortex). New-onset creativity in svPPA may represent a paradoxical functional facilitation. A similar drive for production is found in visually artistic and verbally creative patients. Mirroring the imaging findings in visually artistic patients, verbal preoccupation and creativity may be associated with medial atrophy in the language-dominant temporal lobe, but sparing of lateral dominant temporal and non-dominant posterior cortices.

Error analysis of confrontation naming data in both languages was performed. Research questions were directed toward the between language differences in lexical retrieval abilities, types of errors produced and degree of cognate overlap.Results: Three of the four participants showed significantly higher naming accuracy in first acquired language (L1 relative to the second acquired language (L2 and the largest proportion of error type for those three participants in both L1 and L2 was omission. One of the four participants (linguistically balanced showed no between language accuracy difference. Regarding cognate overlap, there was a trend for higher accuracy for higher cognate words (compared to low.Discussion: This study showed that naming performance in these four individuals was reflective of their relative language proficiency and use patterns prior to their stroke. These findings are consistent with the hierarchical model, in normal bilingual speakers and with persons with bilingual aphasia.

    Full Text Available OBJECTIVE: Aphasia assessment is the first step towards a well- founded language therapy. Language tests need to consider cultural as well as typological linguistic aspects of a given language. This study was designed to determine the standardization, validity and reliability of Language Assessment Test for Aphasia, which consists of eight subtests including spontaneous speech and language, auditory comprehension, repetition, naming, reading, grammar, speech acts, and writing. METHODS: The test was administered to 282 healthy participants and 92 aphasic participants in age, education and gender matched groups. The validity study of the test was investigated with analysis of content, structure and criterion-related validity. For reliability of the test, the analysis of internal consistency, stability and equivalence reliability was conducted. The influence of variables on healhty participants’ sub-test scores, test score and language score was examined. According to significant differences, norms and cut-off scores based on language score were determined. RESULTS: The group with aphasia performed highly lower than healthy participants on subtest, test and language scores. The test scores of healthy group were mostly affected by age and educational level but not affected by gender. According to significant differences, age and educational level for both groups were determined. Considering age and educational levels, the reference values for the cut-off scores were presented. CONCLUSION: The test was found to be a highly reliable and valid aphasia test for Turkish- speaking aphasic patients either in Turkey or other Turkish communities around the world.

    It is debated how language and praxis are co-represented in the left hemisphere (LH). As voxel-based lesion-symptom mapping in LH stroke patients with aphasia and/or apraxia may contribute to this debate, we here investigated the relationship between language and praxis deficits at the behavioral and lesion levels in 50 sub-acute stroke patients. We hypothesized that language and (meaningful) action are linked via semantic processing in Broca's region. Behaviorally, half of the patients suffered from co-morbid aphasia and apraxia. While 24 % (n = 12) of all patients exhibited aphasia without apraxia, apraxia without aphasia was rare (n = 2, 4 %). Left inferior frontal, insular, inferior parietal, and superior temporal lesions were specifically associated with deficits in naming, reading, writing, or auditory comprehension. In contrast, lesions affecting the left inferior frontal gyrus, premotor cortex, and the central region as well as the inferior parietal lobe were associated with apraxic deficits (i.e., pantomime, imitation of meaningful and meaningless gestures). Thus, contrary to the predictions of the embodied cognition theory, lesions to sensorimotor and premotor areas were associated with the severity of praxis but not language deficits. Lesions of Brodmann area (BA) 44 led to combined apraxic and aphasic deficits. Data suggest that BA 44 acts as an interface between language and (meaningful) action thereby supporting parcellation schemes (based on connectivity and receptor mapping) which revealed a BA 44 sub-area involved in semantic processing.

    The assessment of the level and content of consciousness in brain-damaged patients relies to a large extent on behavioral assessment techniques. The limited behavioral repertoire displayed by vegetative and minimally conscious states requires the use of highly sensitive and reliable behavioral assessment methods, allowing the detection of subtle changes in behavior and associated level of consciousness. This situation is further complicated when patients with such disorders of consciousness have underlying deficits in the domain of communication functions, such as aphasia. The present paper examines the consequences of receptive and/or productive aphasia on the already limited behavioral repertoire presented in these patients and discusses a number of behavioral and neuroimaging assessment procedures designed to: (1) detect the presence of aphasia in patients with disorders of consciousness, and (2) reliably assess the level of consciousness of brain-damaged patients while taking into account the existence of receptive and/or expressive language deficits. The combined use of behavioral and neuroimaging assessment techniques appears to be particularly promising for disentangling impaired consciousness and aphasia. PMID:19818894

    2009-04-01

    Full Text Available

    • BACKGROUND: Aphasia diagnosis is particularly challenging due to the linguistic uncertainty and vagueness, inconsistencies in the definition of aphasic syndromes, large number of measurements with  mprecision, natural diversity and subjectivity in test objects as well as in opinions of experts who diagnose the disease.
    • METHODS: Fuzzy probability is proposed here as the basic framework for handling the uncertainties in medical diagnosis and particularly aphasia diagnosis. To efficiently construct this fuzzy probabilistic mapping, statistical analysis is performed that constructs input membership functions as well as determines an effective set of input features.
    • RESULTS: Considering the high sensitivity of performance measures to different distribution of testing/training sets, a statistical t-test of significance is applied to compare fuzzy approach results with NN  esults as well as author’s earlier work using fuzzy logic. The proposed fuzzy probability estimator approach clearly provides better diagnosis for both classes of data sets. Specifically, for the first and second type of fuzzy probability classifiers, i.e. spontaneous speech and comprehensive model, P-values are 2.24E-08 and 0.0059, espectively, strongly rejecting the null hypothesis.
    • CONCLUSIONS: The technique is applied and compared on both comprehensive and spontaneous speech test data for diagnosis of four Aphasia types: Anomic, Broca, Global and Wernicke. Statistical analysis confirms that the proposed approach can significantly improve accuracy using fewer Aphasia features.
    • KEYWORDS: Aphasia, fuzzy probability, fuzzy logic, medical diagnosis, fuzzy rules.

    The Stroke and Aphasia Quality Of Life Scale (SAQOL-39) is a widely used instrument in assessing the quality of life in aphasic patients. Our purpose was to translate the SAQOL-39 into the Turkish language (SAQOL-39/TR) and assess its reliability and validity in patients who had aphasia. SAQOL-39/TR was obtained using the 'translation-backward translation' method and administered to 40 patients with aphasia. The reliability studies were performed by means of internal consistency and test-retest reliability. The validation studies were carried out by means of construct validity using within-scale analyses and analyses against the external criteria. Correlation analysis was performed between scales and the Ege Aphasia Test, the Barthel index, the 12-item General Health Questionnaire and the Brunnstrom recovery stages (BRS) of the arm, hand, and lower extremity. In the results, the scores of the SAQOL-39 were not different between groups. Cronbach's α variables were good for all domains (0.80, 0.88, 0.89, 0.82, and 0.83). Test-retest reliability was also high (0.96, 0.97, 0.91, 0.70, and 0.96). There were significant correlations with coefficients ranging from 0.36 to 0.60 among the domains of scale and other measures. Moderate-high correlations were also seen with BRS-arm, BRS-hand, and BRS-lower extremity (r, 0.27-0.58). It was found that all domains were highly related with all domains of Ege aphasia test, except praxia (P<0.001). This study showed that the SAQOL-39/TR has acceptable validity and reliability in assessing the quality of life. However, similar results of the scale in patients with dysarthria suggest that the SAQOL-39 may not be specific to only aphasic patients. PMID:26954990

    2015-01-01

    Full Text Available Background: Aphasia, an acquired inability to understand and/or speak language, is a common repercussion of stroke that denigrates the quality of life (QOL in the affected persons. Several languages in India experience the dearth of instruments to measure the QOL of persons with aphasia. Malayalam, the language spoken by more than 33 million people in Kerala, the southern state of India, is not an exception to this. Objective: This study aimed to adapt and validate the widely-used stroke-aphasia quality of life (SAQOL-39 scale to Malayalam. Materials and Methods: We required seven Malayalam-speaking Speech Language Pathologists (SLPs, hailing from different regions of Kerala, to examine the socio-cultural suitability of the original items in SAQOL-39 and indicate modifications, wherever necessary. Subsequently, the linguistic adaptation was performed through a forward-backward translation scheme. The socio-culturally and linguistically adapted Malayalam version was then administered on a group of 48 Malayalam-speaking persons with aphasia to examine the test-retest reliability, acceptability, as well as the internal consistency of the instrument. Results: The Malayalam SAQOL-39 scale showed high test-retest reliability (intraclass correlation coefficient, ICC = 0.91 as well as acceptability with minimal missing data (0.52%. Further, it yielded high internal consistency (Chronbach′s ∝ = 0.98 as well as item-to-total and inter-domain correlations. Conclusions: The Malayalam version of SAQOL-39 is the first socio-culturally and linguistically adapted tool to measure the QOL of persons with stroke-aphasia speaking this language. It may serve as a potential tool to measure the QOL of this population in both clinical practice and future research endeavors.

    Full Text Available Background: Stroke is a major detriment to the quality of life (QOL in its victims. Several functional limitations following stroke contribute to the denigrated QOL in this population. Aphasia, a disturbance in the comprehension, processing, and/or expression of language, is a common consequence of stroke. Yet, in most Indian languages, including the national language (Hindi, there are no published tools to measure the QOL of persons with stroke-aphasia. Objective: The current study was carried out to adapt and validate a well-known tool to measure the QOL (i.e., Stroke-Aphasia Quality of Life-39; SAQOL-39 to Hindi. Materials and Methods: We presented the original (English version of the SAQOL-39 to a group of six Hindi-speaking Speech Language Pathologists hailing from the central and northern regions of India to examine the sociocultural suitability of items and indicate modifications, if any. The linguistic adaptation was performed through a forward-backward translation scheme. The socioculturally and linguistically adapted (to Hindi version was then administered on a group of 84 Hindi-speaking persons with aphasia to examine the acceptability, test-retest reliability as well as the internal consistency of the instrument. Results: The SAQOL-39 in Hindi exhibited high test-retest reliability (ICC = 0.9 as well as acceptability with minimal missing data. This instrument exhibited high internal consistency (Chronbach′s ∝ = 0.98 as well as the both item-to-total and inter-domain correlations. Conclusions: The socioculturally and linguistically adapted Hindi version of SAQOL-39 is a robust tool to measure the QOL of persons with stroke-aphasia. It may serve as an essential tool to measure the QOL in this population for both clinical and research purposes.

    This study presents an innovative approach to clinical management in post-stroke aphasia. Specifically, the evidence shows that specific anomia therapy for verbs normalizes DMN integration, thus reflecting the large scope impact of speech therapy. Also, the correlation between DMN integration values and reactivity to SFA/V shows that DMN status before therapy can be predictive of response to specific therapy. Altogether, these results show that functional integration measures of the DMN can highlight prognosis and therapy efficiency in aphasia rehabilitation.

    Iconicity is the non-arbitrary relation between properties of a phonological form and semantic content (e.g. "moo", "splash"). It is a common feature of both spoken and signed languages, and recent evidence shows that iconic forms confer an advantage during word learning. We explored whether iconic forms conferred a processing advantage for 13 individuals with aphasia following left-hemisphere stroke. Iconic and control words were compared in four different tasks: repetition, reading aloud, auditory lexical decision and visual lexical decision. An advantage for iconic words was seen for some individuals in all tasks, with consistent group effects emerging in reading aloud and auditory lexical decision. Both these tasks rely on mapping between semantics and phonology. We conclude that iconicity aids spoken word processing for individuals with aphasia. This advantage is due to a stronger connection between semantic information and phonological forms. PMID:25637775

    2015-10-01

    The present study aimed to investigate neurophysiological substrates of phoneme and word processing in 10 patients with acute aphasia (PWA). More specifically, phoneme discrimination was studied in a passive and active oddball task with respect to different phonemic contrasts, while lexical detection was investigated by presenting infrequent pseudowords among frequent words in a passive oddball task. Concerning phoneme discrimination, PWA in the acute stage had smaller MMN and P300 amplitudes than the norm group for voicing, whereas for place and manner they only demonstrated smaller P300 amplitudes. PWA showed a distinct pattern of impaired phonemic contrast sensitivity, with place displaying the largest amplitude and voicing the smallest. Concerning lexical detection, pseudowords elicited larger responses than words in both groups, but with a delay and larger P200 amplitude for pseudowords in PWA compared to the norm group. For clinical practice, passive tasks seem more suitable than active tasks in acute aphasia. PMID:26197257

    Herein we describe a patient with established corticobasal degeneration with onset of nonfluent aphasia and showing symmetrical cerebral involvement. A 64-year-old man with a speech disorder for 2 years visited our hospital. He had nonfluent aphasia (reduced spontaneous speech, loss of intonation, anomia, repetition disorder, and difficulty in speaking short sentences). He also showed right-sided motor neglect, hypertonus of the left lower limb, a mask-like facial expression, and difficulty in closing his eyes. He was restless and walked around even during examination, suggesting frontotemporal dementia (FTD). Single-photon emission computed tomography (SPECT) revealed symmetrical reduction of cerebral blood flow in the bilateral fronto-temporo-parietal lobes. His neurological condition deteriorated gradually and a year later he could not speak comprehensive sentences. Magnetic resonance imaging (MRI) of the head at age 70 showed symmetrical atrophy of the bilateral fronto-temporal lobes. He died of respiratory failure after clinical problems lasting ten years. On pathological examination, the fixed brain weighed 1,010 g and showed bilateral symmetrical atrophy of the frontal lobes. Histopathological examination revealed neuronal loss and gliosis in the frontal lobes, especially in the frontal convexity, superior frontal gyrus and precentral gyrus. Gallyas-Braak silver staining showed astrocytic plaques, argyrophilic threads and coiled bodies mainly in the frontal lobes. The substantia nigra showed severe neuronal loss on both sides and presence of free melanin. Pathological diagnosis was corticobasal degeneration (CBD). We believe that the patient had nonfluent aphasia and FTD reflected in bilateral degeneration of the frontal lobes. Some cases of CBD may present with symmetrical degeneration of the brain, even though left-hemisphere symptoms such as aphasia reveal themselves at an early stage. PMID:22868886

    A right handed man had a massive left middle cerebral artery stroke. CT and MRI revealed extensive destruction of both anterior and posterior areas typically associated with language. There was, however, no aphasia, but instead a marked limb apraxia, dyscalculia, dense right visual neglect, and anosognosia. These uncommon dissociations and associations support the hypothesis that cerebral control of motor function of the limbs is not fundamentally related to the motor control involved in spee...

    Observable disruptions in spontaneous speech are among the most prominent characteristics of aphasia. The potential of language production analyses in discourse contexts to reveal subtle language deficits has been progressively exploited, becoming essential for diagnosing language disorders (Vermeulen et al., 1989; Goodglass et al., 2000; Prins and Bastiaanse, 2004; Jaecks et al., 2012). Based on previous studies, short and/or fragmentary utterances, and consequently a shorter MLU, are expect...

    Iconicity is the non-arbitrary relation between properties of a phonological form and semantic content (e.g. “moo”, “splash”). It is a common feature of both spoken and signed languages, and recent evidence shows that iconic forms confer an advantage during word learning. We explored whether iconic forms conferred a processing advantage for 13 individuals with aphasia following left-hemisphere stroke. Iconic and control words were compared in four different tasks: repetition, reading aloud, a...

    Aphasia is an acquired language impairment affecting speaking, listening, reading, and writing. Aphasia occurs in about a third of patients who have ischemic stroke and significantly affects functional recovery and return to work. Stroke is more common in older individuals but also occurs in young adults and children. Because people experiencing a stroke are typically aged between 65 and 84 years, hearing loss is common and can potentially interfere with rehabilitation. There is some evidence for increased risk and greater severity of sensorineural hearing loss in the stroke population and hence it has been recommended that all people surviving a stroke should have a hearing test. Auditory processing difficulties have also been reported poststroke. The International Classification of Functioning, Disability and Health (ICF) can be used as a basis for describing the effect of aphasia, hearing loss, and auditory processing difficulties on activities and participation. Effects include reduced participation in activities outside the home such as work and recreation and difficulty engaging in social interaction and communicating needs. A case example of a young man (M) in his 30s who experienced a left-hemisphere ischemic stroke is presented. M has normal hearing sensitivity but has aphasia and auditory processing difficulties based on behavioral and cortical evoked potential measures. His principal goal is to return to work. Although auditory processing difficulties (and hearing loss) are acknowledged in the literature, clinical protocols typically do not specify routine assessment. The literature and the case example presented here suggest a need for further research in this area and a possible change in practice toward more routine assessment of auditory function post-stroke.

    Wernicke's aphasia is characterized by severe word and sentence comprehension impairments. The location of the underlying lesion site, known as Wernicke's area, remains controversial. Questions related to this controversy were addressed in 72 patients with primary progressive aphasia who collectively displayed a wide spectrum of cortical atrophy sites and language impairment patterns. Clinico-anatomical correlations were explored at the individual and group levels. These analyses showed that neuronal loss in temporoparietal areas, traditionally included within Wernicke's area, leave single word comprehension intact and cause inconsistent impairments of sentence comprehension. The most severe sentence comprehension impairments were associated with a heterogeneous set of cortical atrophy sites variably encompassing temporoparietal components of Wernicke's area, Broca's area, and dorsal premotor cortex. Severe comprehension impairments for single words, on the other hand, were invariably associated with peak atrophy sites in the left temporal pole and adjacent anterior temporal cortex, a pattern of atrophy that left sentence comprehension intact. These results show that the neural substrates of word and sentence comprehension are dissociable and that a circumscribed cortical area equally critical for word and sentence comprehension is unlikely to exist anywhere in the cerebral cortex. Reports of combined word and sentence comprehension impairments in Wernicke's aphasia come almost exclusively from patients with cerebrovascular accidents where brain damage extends into subcortical white matter. The syndrome of Wernicke's aphasia is thus likely to reflect damage not only to the cerebral cortex but also to underlying axonal pathways, leading to strategic cortico-cortical disconnections within the language network. The results of this investigation further reinforce the conclusion that the left anterior temporal lobe, a region ignored by classic aphasiology, needs to be

    Full Text Available OBJECTIVE: To establish whether vascular aphasic syndromes can predict stroke outcomes. METHOD: Thirty-seven adults were evaluated for speech and language within 72 hours after a single first-ever ischemic brain lesion, in blind association to CT and/or MR. RESULTS: Speech or language disabilities were found in seven (87.5% of the eight deceased patients and twenty-six (89.7% of the twenty-nine survivors. Global aphasia was identified in eleven patients, all with left hemisphere lesions (nine mute; five deceased, consisting on a risk factor for death in the acute stroke phase (ρ=0.022. Age (z=1.65; ρ>0.09, thrombolysis (ρ=0.591, infarct size (ρ=0.076 and side (ρ=0.649 did not significantly influence survival. Absence of aphasia did not predict a better evolution, regardless of the affected hemisphere. Prevalence of cardiovascular risk factors was similar for all patient groups. CONCLUSION: Global aphasia in acute stroke can adversely affect prognosis, translated into impairment of dominant perisylvian vascular territories, with mutism as an important semiological element.

    Based on findings for overlapping representations of bilingual people's first (L1) and second (L2) languages, unilingual therapies of bilingual aphasia have been proposed to benefit the untrained language. However, the generalisation patterns of intra- and cross-language and phonological therapy and their neural bases remain unclear. We tested whether the effects of an intensive lexical-phonological training (LPT) in L2 transferred to L1 word production in a Persian-French bilingual stroke patient with Broca's aphasia. Language performance was assessed using the Bilingual Aphasia Test, a 144-item picture naming (PN) task and a word-picture verification (WPV) task. Electroencephalography (EEG) was recorded during PN and WPV in both languages before and after an LPT in French on a wordlist from the PN task. After the therapy, naming improved only for the treated L2 items. The naming performance improved neither in the untrained L2 items nor in the corresponding items in L1. EEG analyses revealed a Language x Session topographic interaction at 540 ms post-stimulus, driven by a modification of the electrophysiological response to the treated L2 but not L1 items. These results indicate that LPT modified the brain networks engaged in the phonological-phonetic processing during naming only in the trained language for the trained items. PMID:26010483

    Verbal short-term memory (STM) impairment represents a frequent and long-lasting deficit in aphasia, and it will prevent patients from recovering fully functional language abilities. The aim of this study was to obtain a more precise understanding of the nature of verbal STM impairment in aphasia, by determining whether verbal STM impairment is merely a consequence of underlying language impairment, as suggested by linguistic accounts of verbal STM, or whether verbal STM impairment reflects an additional, specific deficit. We investigated this question by contrasting item-based STM measures, supposed to depend strongly upon language activation, and order-based STM measures, supposed to reflect the operation of specific, serial order maintenance mechanisms, in a sample of patients with single-word processing deficits at the phonological and/or lexical level. A group-level analysis showed robust impairment for both item and serial order STM aspects in the aphasic group relative to an age-matched control group. An analysis of individual profiles revealed an important heterogeneity of verbal STM profiles, with patients presenting either selective item STM deficits, selective order STM deficits, generalized item and serial order STM deficits or no significant STM impairment. Item but not serial order STM impairment correlated with the severity of phonological impairment. These results disconfirm a strong version of the linguistic account of verbal STM impairment in aphasia, by showing variable impairment to both item and serial order processing aspects of verbal STM.

    Full Text Available The article discusses the semiology of aphasias, which started being developed in the 19th century by Broca and Wernicke. We do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. We also discuss the contributions of Luria and Jakobson to a better understanding of how language is affected in aphasias and how Modern Linguistics, in special the Discursive Neurolinguistics, may enlighten the debate. We analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

    2015-05-01

    Full Text Available Introduction: Many patients with aphasia, particularly those with nonfluent aphasia, have been observed to be able to sing the lyrics of songs more easily than they can speak the same words (Wan et al., 2010. The observation that not only singing, but even intoning words, can facilitate speech output in nonfluent aphasia patients provided the foundation for Melodic Intonation Therapy (MIT; Sparks, 1974, an intensive therapy lasting ten or more weeks (Schlaug et al., 2008. The current study aims to look at patients with aphasia in their ability to complete song lyrics by either singing, speaking, or humming them. Methods: Thus far, 11 patients with aphasia and 6 age- matched healthy controls have participated in an experimental stem-completion task examining singing abilities. The task consists of three conditions each consisting of 20 well-known songs and all participants completed all three conditions. Participants heard the first half of a phrase that was either sung in its original format (e.g., “Mary had a Little Lamb”, spoken, or intoned on the syllable “bum”, and were asked to complete the phrase according to the format in which the stimulus was presented, (i.e., either by singing, speaking the words, or humming/singing the melody correspondingly. The task was untimed, though most finished the task within an hour. Each participant completed a survey about their musical experience. Results: Patients were scored on their ability to complete the melody and words together in the sung condition, only the words in the spoken condition, and only the tune of the song in the melody condition. A parametric t-test indicated no significant difference between groups in the sung condition (mean patients=45.3%, mean controls=68.2%, t-value= -1.96, p=0.0684, though this test almost reached significance. There was also no significant difference between groups in the melody condition (mean patients= 18.2%, mean controls=20.0%, t-value= -0.335, p=0

    Sadhvi Saxena

    2014-04-01

    Full Text Available A growing body of work suggests that processing hierarchical structure in language and in music rely on shared systems (review: Slevc, 2012, however this conclusion is tempered by neuropsychological dissociations between linguistic and musical processing (i.e., aphasia and amusia; review: Peretz, 2006. An influential reconciliation comes from Patel’s (2003 shared syntactic integration resource hypothesis (SSIRH, which suggests that evidence for shared processes reflect reliance on shared syntactic integration processes whereas dissociations result from damage to domain-specific syntactic representations. The SSIRH thus predicts that patients with deficits in the processing of linguistic syntax–such as agrammatic aphasics–should show parallel deficits in musical structural (harmonic processing. This prediction is countered by findings of impaired harmonic processing in patients with (apparently spared linguistic syntactic processing (e.g., Sammler et al., 2011, however evidence for the opposite dissociation–preserved harmonic processing in agrammatic aphasia–is lacking. While there are reports of preserved musical abilities despite global aphasia (Basso & Capitani, 1985 or severe Wernicke’s aphasia (Luria, Tsvetkova, & Futer, 1965, of preserved reading and writing of music in the face of alexia and agraphia (Signoret et al., 1987, and of preserved musical sound naming in the face of severe anomia (Tzortzis et al., 2000, no study (to our knowledge has demonstrated preserved musical structural processing in an agrammatic patient. In addition, at least one group of agrammatic aphasics did not show normal effects of harmonic priming, and showed a relationship between accuracy on acceptability judgments in language and in music (Patel et al., 2008. Here, we report a detailed analysis of structural processing in language and in music in HV, a 63 year-old native English-speaking female musician who sustained a left peri-Sylvian stroke. She

    Full Text Available Primary progressive aphasia (PPA is a focal neurodegeneration of the brain affecting the language network. Patients can have isolated language impairment for years without impairment in other areas. PPA is classified as primary progressive nonfluent aphasia (PNFA, semantic dementia (SD, and logopenic aphasia, which have distinct patterns of atrophy on neuroimaging. PNFA and SD are included under frontotemporal lobar degenerations. PNFA patients have effortful speech with agrammatism, which is frequently associated with apraxia of speech and demonstrate atrophy in the left Broca′s area and surrounding region on neuroimaging. Patients with SD have dysnomia with loss of word and object (or face meaning with asymmetric anterior temporal lobe atrophy. Logopenic aphasics have word finding difficulties with frequent pauses in conversation, intact grammar, and word comprehension but impaired repetition for sentences. The atrophy is predominantly in the left posterior temporal and inferior parietal regions. Recent studies have described several progranulin mutations on chromosome 17 in PNFA. The three clinical syndromes have a less robust relationship to the underlying pathology, which is heterogeneous and includes tauopathy, ubiquitinopathy, Pick′s disease, corticobasal degeneration, progressive supranuclear palsy, and Alzheimer′s disease. Recent studies, however, seem to indicate that a better characterization of the clinical phenotype (apraxic, agrammatic, semantic, logopenic, jargon increases the predictive value of the underlying pathology. Substantial advances have been made in our understanding of PPAs but developing new biomarkers is essential in making accurate causative diagnoses in individual patients. This is critically important in the development and evaluation of disease-modifying drugs.

A expressão gráfica nos dois casos foi mais atingida como sonseqüência de estar menos automatizada. O fenômeno da perseveração foi notado na fala no primeiro caso e, na escrita, no seguno. Foi discutida a justificativa do diagnóstico e lembrado o diagnóstico diferencial com outros distúrbios da fala em crianças.Two cases of aphasia in children are reported. In the first patient, a girl aged 10, aphasia ocurred after a gunshot cerebral wound and in the second, a boy aged 8, there was cerebral trombophlebitis and septicemia. Both patients had normal perception but presented difficulties in expressive functions, sometimes suggesting amnestic gaps. Graphic expression, less automatic than other forms of expression at their ages, was severely impaired. Perseveration was present in oral expression in the first patient, and in writing in the second. Clinical improvement was good in both cases. Some points of differential diagnosis of aphasia in children are discussed.

  3. Integrating Lesion-Symptom Mapping with Other Methods to Investigate Language Networks and Aphasia Recovery

    Directory of Open Access Journals (Sweden)

    Peter E Turkeltaub

    2015-04-01

    Full Text Available Voxel-based lesion-symptom mapping (VLSM has provided valuable insights into the neural underpinnings of various language functions. Integrating lesion mapping methods with other neuroscience techniques may provide new opportunities to investigate questions related both to the neurobiology of language and to plasticity after brain injury. For example, recent diffusion tensor imaging studies have explored relationships between aphasia symptomology and damage in specific white matter tracts (Forkel et al., 2014 or disruption of the white matter connectome (Bonilha, Rorden, & Fridriksson, 2014. VLSM has also recently been used to assess correlations between lesion location and response to transcranial direct current stimulation aphasia treatment (Campana, Caltagirone, & Marangolo, 2015. We have recently undertaken studies integrating VLSM with other techniques, including voxel-based morphometry (VBM and functional MRI, in order to investigate how parts of the brain spared by stroke contribute to recovery. VLSM can be used in this context to map lesions associated with particular patterns of plasticity in brain structure, function, or connectivity. We have also used VLSM to estimate the variance in behavior due to the stroke itself so that this lesion-symptom relationship can be controlled for when examining the contributions of the rest of the brain. Using this approach in combination with VBM, we have identified areas of the right temporoparietal cortex that appear to undergo hypertrophy after stroke and compensate for speech production deficits. In this talk, I will review recent advances in integrating lesion-symptom mapping with other imaging and brain stimulation techniques in order to better understand the brain basis of language and of aphasia recovery.

    Eye movement trajectories during a verbally cued object search task were used as probes of lexico-semantic associations in an anomic patient with primary progressive aphasia. Visual search was normal on trials where the target object could be named but became lengthy and inefficient on trials where the object failed to be named. The abnormality was most profound if the noun denoting the object could not be recognized. Even trials where the name of the target object was recognized but not retrieved triggered abnormal eye movements, demonstrating that retrieval failures can have underlying associative components despite intact comprehension of the corresponding noun.

    Multiple factors may contribute to the development of emergence delirium in a child. We present the case of a healthy 12-year-old girl who received preoperative midazolam with the desired anxiolytic effect, underwent a brief general anesthetic, and then exhibited postoperative delirium, consisting of a transient associative agnosia and expressive aphasia. Administration of flumazenil led to immediate and lasting resolution of her symptoms. We hypothesize that γ-aminobutyric acid type A receptor-mediated effects, most likely related to an atypical offset of midazolam, are an important subset of emergence delirium that is amenable to pharmacologic therapy with flumazenil.

    - What are the challenges of using tDCS for hypothesis testing and how can I reduce the risk of misinterpreting my results? In summary, the symposium is designed to (a promote the theoretical understanding of the basic science of tDCS, and (b to tackle several pragmatic issues when designing tDCS studies, with the ultimate goal of cultivating higher standards for using a potentially invaluable technique for both clinical and research purposes. Given the growing interest in the aphasia community for using tDCS and the sophistication of the audience, we believe that the Academy’s annual meeting is the ideal venue for this symposium.

  9. The study of correlation between neurological function rehabilitation and dynamic change of rCBF in patients with aphasia

    International Nuclear Information System (INIS)

    Objective: To evaluate the result of SPECT and CT in the patients with acute cerebral infarction and further more, to study the correlation between aphasia and dynamic change of regional cerebral blood flow (rCBF) in patients. Methods: Thirty cases with cerebral infarction of left basal ganglia were divided into two groups according to the presence or absence of aphasia; the vision and semi-ration analysis were used in photograph reading and region of interest (ROI) technology, respectively. Results: 1) Group A: there was a low rCBF in left basal ganglia, the dimension was larger than that in CT. There was also a low rCBF in frontal lobe and temporal lobe. Group B: there was only a low rCBF in left basal ganglia. 2) There were 6 cases with crossed cerebellar diaschisis (CCD) in the patients with aphasia. 3) The comparison about aphasia: the rCBF was higher in language center in the patients with improved language function than that in the patients without language function improvement and the difference between them was significant. Conclusions: The neurological function can be indirectly reflected through the study of the rCBF. At the same time, it may conduce to the locating of the damage in the central nervous system and to the differentiation diagnosis. It may also conduce to the programming of the therapeutic course and prognostication. (authors)

    Wilkinson, Ray; Lock, Sarah; Bryan, Karen; Sage, Karen

    2011-02-01

    This paper discusses the implementation and evaluation of an interaction-focused intervention single case study for a couple where one partner has aphasia. Drawing on conversation analytic research, naturally occurring conversations of the couple at home pre- and post-intervention were collected and analysed. Analysis of the speaker with aphasia's topic initiating turns in the pre-intervention conversation showed that in each case a feature of the attempt was that the speaker had difficulty in getting the topic initiation accepted and established. Drawing on conversation analytic work on topic initiations in normal conversation, intervention focused on training the couple to co-produce these topic initiating turns of the speaker with aphasia in a collaborative and step-by-step manner. Post-intervention, there was evidence that the couple were now using this new method, albeit in a slightly different way to that worked on in the intervention sessions. Drawing on work into adaptation by speakers with aphasia and their conversation partners, these results are discussed in terms of a process of mutual adaptation by the couple. PMID:21329413

    Neuropsychological alterations after stroke depend on the type and site of the injury and may result in cognitive, mood or social disabilities. The disorders may disturb daily motor activities and may alter language and short- and long-term memory. Patients that have suffered a stroke in the left temporal hemisphere may present acoustic-mnestic aphasia and memory alterations. Our objective was to evaluate the results of the implementation of a memory reinforcement training program in patients with acoustic-mnestic aphasia, and to know if the program improves memory consolidation for a better patient's quality of life. We performed a case-report study, before and after implementation of a memory reinforcement program in two patients with acoustic-mnestic aphasia and memory alterations. The program was constructed with 20 supra-ordinal categories, each with 10 sub-ordinal words, with a total of 200 words to evoke. We found significant differences in the number of evoked words and in memory consolidation after the implementation of the program in the two studied patients. Our observations suggest that implementation of a memory reinforcement program in subjects with acoustic-mnestic aphasia may be useful in the rehabilitation of memory alterations in these patients.

    2008-01-01

    Although the notion of the language specificity of neural correlates has been widely accepted in the past (e.g., lefthemispheric dominance including Broca's and Wernike's area, N400 ERP component of semantic processing, and the P600 ERP component of syntactic processing, etc.), recent studies have shown that music and language share some important neurological aspects in their processing, both involving bilateral hemispheric activities. In line with this are the frequent behavioral clinical observations that persons with aphasia show improved articulation and prosody of speech in musically assisted phrases. Connecting recent neurological findings with clinical observations would not only inform clinical practice but would enhance understanding of the neurological mechanisms involved in the processing of speech/language and music. This article presents a music therapy treatment protocol study of 7 nonfluent patients with aphasia. The data and findings are discussed with regard to some of the recent focuses and issues addressed in the experimental studies using cognitive-behavioral, electrophysiological, and brain-imaging techniques.

  18. Phonetic basis of phonemic paraphasias in aphasia: Evidence for cascading activation.

    Science.gov (United States)

    Kurowski, Kathleen; Blumstein, Sheila E

    2016-02-01

    Phonemic paraphasias are a common presenting symptom in aphasia and are thought to reflect a deficit in which selecting an incorrect phonemic segment results in the clear-cut substitution of one phonemic segment for another. The current study re-examines the basis of these paraphasias. Seven left hemisphere-damaged aphasics with a range of left hemisphere lesions and clinical diagnoses including Broca's, Conduction, and Wernicke's aphasia, were asked to produce syllable-initial voiced and voiceless fricative consonants, [z] and [s], in CV syllables followed by one of five vowels [i e a o u] in isolation and in a carrier phrase. Acoustic analyses were conducted focusing on two acoustic parameters signaling voicing in fricative consonants: duration and amplitude properties of the fricative noise. Results show that for all participants, regardless of clinical diagnosis or lesion site, phonemic paraphasias leave an acoustic trace of the original target in the error production. These findings challenge the view that phonemic paraphasias arise from a mis-selection of phonemic units followed by its correct implementation, as traditionally proposed. Rather, they appear to derive from a common mechanism with speech errors reflecting the co-activation of a target and competitor resulting in speech output that has some phonetic properties of both segments.

    In 1877, Barlow described a ten-year-old boy with right hemiplegia and aphasia, quick recovery of language function, and subsequent left hemiplegia and aphasia, who was shown to have symmetrical left and right Broca's area lesions at autopsy. The report of this case motivated many writers in the second half of the nineteenth century to develop theories on localization, laterality, equipotentiality and development of specialization, recovery of function, and the role of the right hemisphere (see Finger et al., 2003, for review). This paper presents an analysis of the original archived case notes that have recently come to light. Examination reveals discrepancies in significant details of the history of the case and raises questions about the degree of impairment and recovery throughout his illness as reported in the published article. Consideration of these differences between the presentation of the case in the British Medical Journal publication and the documentation in the original patient records raises issues about the validity of this case as evidence for the many arguments it was to support that have persisted to the present.

    Most neurological lesion studies emphasize performance deficits that result from focal brain injury. Here, we describe striking gains of function in a patient with primary progressive aphasia, a degenerative disease of the human language network. During the decade before her language deficits arose, Anne Adams (AA), a lifelong scientist, developed an intense drive to produce visual art. Paintings from AA's artistic peak revealed her capacity to create expressive transmodal art, such as renderings of music in paint, which may have reflected an increased subjective relatedness among internal perceptual and conceptual images. AA became fascinated with Maurice Ravel, the French composer who also suffered from a progressive aphasia, and painted his best-known work, 'Boléro', by translating its musical elements into visual form. Later paintings, achieved when AA was nearly mute, moved towards increasing photographic realism, perhaps because visual representations came to dominate AA's mental landscape during this phase of her illness. Neuroimaging analyses revealed that, despite severe degeneration of left inferior frontal-insular, temporal and striatal regions, AA showed increased grey matter volume and hyperperfusion in right posterior neocortical areas implicated in heteromodal and polysensory integration. The findings suggest that structural and functional enhancements in non-dominant posterior neocortex may give rise to specific forms of visual creativity that can be liberated by dominant inferior frontal cortex injury.

    Objective: To explore the best remedies for cerebral palsy with aphasia. Methods: A total of 76 cases of cerebral palsy children with aphasia were evenly randomized into control group and treatment group. Patients of treatment group were treated with "consciousness-restoring needling" plus linguistic training and those of control group treated with simple linguistic training method. Acupuncture was given once every other day, and linguistic training conducted once 6 times a week, with 10 times being a therapeutic course and the interval between two weeks being 10 -15 days. Following 3 courses of treatment, the therapeutic effect was analyzed. Results: After 3 courses of treatment, of the two 38 cases in treatment and control groups, 27 (71.1%) and 13 (34.2%) had remarkable improvement in their symptoms. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.01). The developmental quotient values of speech of treatment and control groups were 56.36 ±19.77 and 46.96±15.63 respectively, displaying that acupuncture could significantly improve cerebral palsy patients' speaking ability (P<0.05). Conclusion: The therapeutic effect of acupuncture therapy plus linguistic training is significantly superior to that of simple linguistic training.

  2. Duration of content and function words in oral discourse by speakers with fluent aphasia: Preliminary data

    Words that had occurred ten times or more in the speech materials was arbitrarily categorized as ‘unique words’ that could more reliably reflect syllable duration. There were a total of 206 unique words (141 content and 65 function words in the aphasia speech materials and 253 unique words (187 content and 66 function in the normal materials, most of them were disyllabic or monosyllabic. A higher lexical diversity in the normal group, but similar number of different function words for both groups, was consistent with earlier findings of impaired lexical access in aphasia. Table 1 displays the average duration per syllable and per word for content and function words among the two speaker groups. Our study showed that word duration in aphasic speech was longer than that in control speech. This is in line with our earlier results of higher speaking rate in normal speech. While content words were longer than function words in the aphasic speech, the difference was not as significant as that in controls.

    There is increasing evidence that a bilingual person should not be considered as two monolinguals in a single body, a view that has gradually been adopted in the diagnosis and treatment of bilingual aphasia. However, its investigation is complicated due to the large variety in possible language combinations, pre- and postmorbid language proficiencies, and age of second language acquisition. Furthermore, the tests and tasks used to assess linguistic capabilities differ in almost every study, hindering a direct comparison of their outcomes. Behavioral, electrophysiological, and neuroimaging data from healthy population show that the processing of second language domains (semantics, syntax, morphology) depends on factors such as age and method of acquisition, proficiency level and environment in which the second language was acquired. A number of single and multiple case reports that rely on behavioral testing of bilingual aphasics replicate these results. Additionally, they show that the patient's performance depends on the size and location of the lesion, as well as language typology and morphological characteristics. Furthermore, the impairment and recovery patterns and recovery generalization from treated to untreated language depend on the lexical and orthographic distances between the two languages. For healthy bilinguals, language processing is usually studied in comparison to monolinguals. We advocate that a good starting point for identifying patterns specific for bilingual aphasia is to compare patient studies of bilinguals and monolinguals.

    2015-04-01

    Full Text Available Introduction Prosody refers to the part of phonology that includes speech rhythm, stress, and intonation (Gandour, 1998. Proper intonation is crucial for expressing one’s emotion and linguistic meaning. Most studies examining prosodic deficits have been primarily focused on Broca’s aphasia (e.g., Danly & Shapiro, 1982. The current study proposed a computer-assisted method for systematic and objective examination of intonation patterns in aphasic oral discourse. The speech materials were in Hong Kong Cantonese, which is known of being rich in tones. Since surface F0 contour is the result of complicated interplay between sentence-level intonation and syllable-level lexical tones, the challenge is on how to extract meaningful representations of intonation from acoustic signals. Methods Four individuals with fluent aphasia (two anomic and two transcortical sensory and four gender-, age-, and education-matched controls participated. Based on the Cantonese AphasiaBank protocol (Kong, Law, & Lee, 2009, narrative samples and corresponding audio recordings were collected using discourse tasks of personal monologue, picture and sequential description, and story-telling. There were eight recordings for each subject. Each oral discourse was divided into sentences by manual inspection of the orthographic transcription and the respective acoustic signal. A sentence was defined as a sequence of words that in principle covers a complete thought. However, it was common in spontaneous oral discourse, especially in aphasia, that some of the sentences did not end with a completed expression but switched to a new topic. Occasionally, an obvious interjection was observed during an attempt of restarting a statement. Phoneme-level automatic time alignment was performed on each audio recording using hidden Markov model (HMM based forced alignment technique (Lee, Kong, Chan, & Wang, 2013. F0 was estimated from the acoustic signal at intervals of 0.01 second by

  5. Using lexical variables to predict picture-naming errors in jargon aphasia

    2015-04-01

    Full Text Available Introduction Individuals with jargon aphasia produce fluent output which often comprises high proportions of non-word errors (e.g., maf for dog. Research has been devoted to identifying the underlying mechanisms behind such output. Some accounts posit a reduced flow of spreading activation between levels in the lexical network (e.g., Robson et al., 2003. If activation level differences across the lexical network are a cause of non-word outputs, we would predict improved performance when target items reflect an increased flow of activation between levels (e.g. more frequently-used words are often represented by higher resting levels of activation. This research investigates the effect of lexical properties of targets (e.g., frequency, imageability on accuracy, error type (real word vs. non-word and target-error overlap of non-word errors in a picture naming task by individuals with jargon aphasia. Method Participants were 17 individuals with Wernicke’s aphasia, who produced a high proportion of non-word errors (>20% of errors on the Philadelphia Naming Test (PNT; Roach et al., 1996. The data were retrieved from the Moss Aphasic Psycholinguistic Database Project (MAPPD, Mirman et al., 2010. We used a series of mixed models to test whether lexical variables predicted accuracy, error type (real word vs. non-word and target-error overlap for the PNT data. As lexical variables tend to be highly correlated, we performed a principal components analysis to reduce the variables into five components representing variables associated with phonology (length, phonotactic probability, neighbourhood density and neighbourhood frequency, semantics (imageability and concreteness, usage (frequency and age-of-acquisition, name agreement and visual complexity. Results and Discussion Table 1 shows the components that made a significant contribution to each model. Individuals with jargon aphasia produced more correct responses and fewer non-word errors relative to

    Results suggested that Korean-speaking individuals with aphasia produced more numbers of different verbs, number of verbs per utterance and higher VNRs than English speakers. Both groups generated more words in story. The significant two-way interactions between the language group and task type suggested that there are task-specific effects on linguistic measures across the groups. The study implied that the linguistic characteristics differentially affected language symptoms of aphasia across the different languages and task types.

    Full Text Available Background: The spontaneous and narrative language of Kiswahili agrammatic aphasic and non-brain-damaged speakers was analysed. The bilingual participants were also tested in English to enable comparisons of verb production in the two languages. The significance of this study was to characterise bilingual Kiswahili-English spontaneous agrammatic output. This was done by describing Kiswahili-English bilingual output data with a specific focus on the production of verbs. The description involves comparison of verb and argument production in Kiswahili and English. Methods and procedures: The participants recruited for this study were drawn from two groups of participants (six non-fluent aphasic/agrammatic speakers and six non-braindamaged. From each participant, a sample of spontaneous output was tape-recorded in English and Kiswahili based on the description and narration of the Flood rescue picture’ and the ‘Cookie theft picture’. The data elicited were compared for each subject and between the participants and relevant verb parameters have been analysed. The variables that were studied included mean length of utterance (MLU, inflectional errors, verb tokens and types, copulas and auxiliaries. Further, all verbs produced were classified as per their argument structure. Results: The results from English data supported previous findings on agrammatic output. The agrammatic participants produced utterances with shorter MLU and simpler sentence structure. However, Kiswahili data surprisingly showed reversed results, with agrammatic speakers producing longer utterances than non-brain-damaged (NBD controls. The results also revealed selective impairment in some agrammatic speakers who made inflectional errors. The verb argument structure showed contrasting results, with agrammatic speakers preferring transitive verbs whilst the NBD speakers used more intransitive verbs.Conclusions: The study attempts for the first time to characterise English

    Chinese college students have learned English for years, but they have put too much emphasis on English language and the culture in English speaking countries and societies. Therefore, they have great difficulty in expressing their own traditional culture in English, failing in inter-cultural communication. Since the foreign language education in China has almost occupied by English and its culture, linguistic imperialism and educational imperialism come into our vision. This paper makes a survey on Aphasia of Chinese Culture among Chinese college students, including the textbooks used and students' performance in specific Chinese culture items. And this paper aims at getting to know its current situation and tries to find possible solutions to this problem.

    Full Text Available There are individuals who have a progressive language deficit without presenting cognitive deficits in other areas. One of the diseases related to this presentation is primary progressive aphasia (PPA. OBJECTIVE: Identify by means of diffusion tensor imaging (DTI and measurements of cortical volume, brain areas that lead to dysphasia when presenting signs of impaired connectivity or reduced volume. METHOD: Four patients with PPA were evaluated using DTI, and measurements of cortical volumes in temporal areas. These patients were compared with two normal volunteers. RESULTS: There is a trend to a difference in the number and volume of related fibers between control group and patients with PPA. Comparing cortical volumes in temporal areas between groups yielded a trend to a smaller volume in PPA patients. CONCLUSION: Patients with PPA have a trend to impairment in cortical and subcortical levels regarding relevant areas.

    The purpose of this study was to determine if differential reading and spelling mechanisms were involved in a Japanese patient with aphasia. In our case, the patient scored low on all of the administered reading tasks, suggesting that both the reading lexical and non-lexical routes were impaired. In contrast, his writing-to-dictation score for Kana nonwords was high, suggesting that the spelling non-lexical route was intact. However, the patient scored low on a writing-to-dictation task comprised of high-familiarity Kanji words. The spelling lexical route was thought to be impaired.

    No significant correlations were observed between performance on complex span task and N-back tasks.Furthermore, performance on the modified listening span was related to performance on the comprehension subtest of the QASA, while no relationship was found for 2-back and 0-back tasks.Our results mirror studies in healthy controls that demonstrated no relationship between performance on the two tasks(Jaeggi et al., 2010; Kane et al., 2007. Thus although N-back tasks seem similar to traditional complex span measures and may also index abilities related to cognitive processing, the evidence to date does not warrant their direct association with the construct of WM. Implications for future investigation of cognitive deficits in aphasia will be discussed.

    Full Text Available There is an increased interest in reading impairments in the Japanese language, due to its particular writing system which includes two different scripts, Kanji (logograms and Kana (phonograms. Reading dissociations between Kanji and Kana have been described, showing that each system is processed differently by the cerebral hemispheres. We describe the case of a 68 year old Brazilian “nisei” (i.e. born from Japanese parents who had knowledge of both Japanese and Portuguese. He presented an ischemic stroke affecting the right hemisphere and subsequently developed a Broca's aphasia and an unexpected reading dissociation, with an impairment in Kana reading comprehension and a good performance in Kanji and in Portuguese. These findings suggest that the patient's right and left hemispheres have assumed opposite roles not only for oral but also for written language decodification.

    Baseline measures of naming nouns and verbs in single words, and sentences, were obtained. While there was no improvement in production of nouns or verbs in single words or sentence production after sham tDCS, and no improvement of noun production after anodal tDCS and speech-language treatment, production of verbs in sentences improved after a 10-session treatment block of anodal tDCS and behavioral therapy. Conclusion Administering a behavioral treatment that is impairment-based as well as functionally-based in conjunction with tDCS is both feasible and promising. Anodal tDCS in conjunction with behavioral intervention is a treatment approach that warrants continued investigation. The results will be discussed in relation to the tDCS and aphasia literature.

    The relationship between recursive sentence embedding and theory-of-mind (ToM) inference is investigated in three persons with Broca's aphasia, two persons with Wernicke's aphasia, and six persons with mild and moderate Alzheimer's disease (AD). We asked questions of four types about photographs of various real-life situations. Type 4 questions asked participants about intentions, thoughts, or utterances of the characters in the pictures ("What may X be thinking/asking Y to do?"). The expected answers typically involved subordinate clauses introduced by conjunctions or direct quotations of the characters' utterances. Broca's aphasics did not produce answers with recursive sentence embedding. Rather, they projected themselves into the characters' mental states and gave direct answers in the first person singular, with relevant ToM content. We call such replies "situative statements." Where the question concerned the mental state of the character but did not require an answer with sentence embedding ("What does X hate?"), aphasics gave descriptive answers rather than situative statements. Most replies given by persons with AD to Type 4 questions were grammatical instances of recursive sentence embedding. They also gave a few situative statements but the ToM content of these was irrelevant. In more than one third of their well-formed sentence embeddings, too, they conveyed irrelevant ToM contents. Persons with moderate AD were unable to pass secondary false belief tests. The results reveal double dissociation: Broca's aphasics are unable to access recursive sentence embedding but they can make appropriate ToM inferences; moderate AD persons make the wrong ToM inferences but they are able to access recursive sentence embedding. The double dissociation may be relevant for the nature of the relationship between the two recursive capacities. Broca's aphasics compensated for the lack of recursive sentence embedding by recursive ToM reasoning represented in very simple

    Full Text Available The paper reports findings derived from three experiments examining syntactic and morphosyntactic processing in individuals with agrammatic and logopenic variants of primary progressive aphasia (PPA-G and PPA-L, respectively and stroke-induced agrammatic and anomic aphasia (StrAg and StrAn, respectively. We examined comprehension and production of canonical and noncanonical sentence structures and production of tensed and nontensed verb forms using constrained tasks in experiments 1 and 2, using the Northwestern Assessment of Verbs and Sentences (NAVS [57] and the Northwestern Assessment of Verb Inflection (NAVI, Thompson and Lee, experimental version test batteries, respectively. Experiment 3 examined free narrative samples, focusing on syntactic and morphosyntactic measures, i.e. production of grammatical sentences, noun to verb ratio, open-class to closed-class word production ratio, and the production of correctly inflected verbs. Results indicate that the two agrammatic groups (i.e., PPA-G and StrAg pattern alike on syntactic and morphosyntactic measures, showing more impaired noncanonical compared to canonical sentence comprehension and production and greater difficulties producing tensed compared to nontensed verb forms. Their spontaneous speech also contained significantly fewer grammatical sentences and correctly inflected verbs, and they produced a greater proportion of nouns compared to verbs, than healthy speakers. In contrast, PPA-L and StrAn individuals did not display these deficits, and performed significantly better than the agrammatic groups on these measures. The findings suggest that agrammatism, whether induced by degenerative disease or stroke, is associated with characteristic deficits in syntactic and morphosyntactic processing. We therefore recommend that linguistically sophisticated tests and narrative analysis procedures be used to systematically evaluate the linguistic ability of individuals with PPA, contributing to

  2. Carotid angioplasty with stenting for chronic internal carotid artery occlusion: technical note

    International Nuclear Information System (INIS)

    Carotid angioplasty with stenting (CAS) is becoming accepted as an effective and reliable treatment option for severe carotid artery stenosis. However, it is rarely applied for carotid occlusion, especially in its chronic stage. We report our experience of CAS for chronic internal carotid artery occlusion representing compromised cerebral blood flow using various protection methods. A 77-year-old woman, who was already diagnosed with severe left internal carotid artery stenosis, suddenly had right hemiparesis and aphasia. At that time, she was treated conservatively because her neurological status was quite good, in spite of left carotid artery occlusion. Her symptoms improved in the short term, except slight aphasia, but deteriorated again 18 days from the onset, and magnetic resonance imaging (MRI) showed new ischemic lesions. CAS was then performed for the occluded carotid artery on the 23rd day from the first onset. Using the proximal protection technique, the occluded lesion was crossed carefully with a microguidewire. Stents were also placed successfully with the distal protection technique. The occluded carotid artery was completely recanalized without any unfavorable events or neurological deterioration. In this patient, CAS was successfully to treat chronic carotid artery occlusion. These procedures and techniques are reviewed and discussed. (orig.)

    Introduction Anomia is a core diagnostic marker for Alzheimer’s Disease (AD) and Primary Progressive Aphasia (PPA). There persists controversy as to the locus of the associated naming impairment. Upon one view, anomia reflects loss of core semantic processes that support object knowledge. An alternative perspective holds that anomia reflects access-like impairments. Since aspects of a picture are not equally meaningful for naming, the feature-based spatial precision (e.g., does a patient...

    Objective To investigate the clinical application value of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery in Chinese patients with post-stroke aphasia. Methods Cognitive functions of 59 Chinese patients with aphasia following a stroke were assessed with the Chinese version of the second edition of LOTCA battery and their linguistic functions were tested with the Western Aphasia Battery (WAB) Scale, respectively. The results of LOTCA were analyzed and compared across different groups, in the light of gender, age, educational background, the length of illness, and the degree of aphasia. Results Neither the score of subtests of the LOTCA nor the overall scores of LOTCA of aphasia patients with different gender and educational background differed (all P>0.05). In different age groups, apart from thinking operation (F=3.373, P=0.016), visuomotor organization (F=3.124, P=0.022), attention (F=3.729, P=0.009) and the total score (F=2.683, P=0.041), there was no difference in terms of the other subtest scores of LOTCA (all P>0.05). In the groups of different length of time with illness, apart from orientation (F=2.982, P=0.039) and attention (F=3.485, P=0.022), the score of other subtests and the total score of LOTCA were not different (all P>0.05). In the groups of different degree of aphasia, apart from attention (F=2.061, P=0.074), both the score of other subtests and the total score of LOTCA differed (all P Conclusion LOTCA might be suitable to assessing the cognitive ability of post-stroke Chinese patients with aphasia.

The bullet entered the right parietooccipitaljunction, traveled diagonally through the occipitalpole and ended in the left fronto-temporal lobe. Hedeveloped right hemiparesis and global aphasia. He wasenrolled in speech therapy (ST, and was started onlevetiracetam (LEV 500 mg twice daily (BID for seizureprophylaxis, then LEV was increased to 750mg BID.After 8 days on LEV 750 mg BID the patient pronouncedthe names of his children and answered questionsappropriately with verbal “yes” and “no”. At discharge,FIM scores in comprehension, expression, memory, andsocial interaction had all improved from 2 to 4. He wasable to respond verbally at the 1-3 word level with 50%accuracy and had shown improvement in auditorycomprehension and verbal expression. The patient waskept on LEV 750 mg BID for 7 months. He had 50outpatient ST sessions. At 9 months, he was able to reada paragraph he had written, and used a paper guide toscan lines. His comprehension of the written languageimproved to the sentence level, and his moneymanagement skills improved to modified independent.Conclusions: LEV appears to improve aphasia andcognitive outcomes of PBI patients treated with ST. Largeprospective randomized trials are needed to confirm thisclinical observation and to establish treatment protocolsfor PBI-induced aphasia that will incorporate ST and LEV.

    Development has been made on the element technologies for a home rehabilitation system for aphasia patients. First, studies were performed on an authoring procedure for aphasia patient training, and partial trial production and development were carried out on an authoring system for the training program formula. Then, studies were executed on a training simulation and analysis filter, and partial trial production and development were implemented on a home rehabilitation supporting and self-teaching system. Next, an input and output mechanism for voice signal processing was studied, and aphasia patient and caregiver human interface was partially fabricated on a trial basis. In addition, a remote rehabilitation communicating method was researched, and partial trial production was carried out on a remote rehabilitation evaluation and diagnosis support means. Finally, communication assisting means were researched, and a communication assisting system was partially produced on a trial basis. Good evaluation results were given on a demonstration system. Although partial indications were given on minute parts, practical agreement was obtained as a whole. Great expectation was given particularly on the remote rehabilitation system and the authoring system. (NEDO)

    It is often clinically difficult to assess the severity of aphasia in the earliest stage of cerebral infarction. A method enabling objective assessment of verbal function is needed for this purpose. We examined whether diffusion tensor (DT) tractography is of clinical value in assessing aphasia. Thirteen right-handed patients with left middle cerebral artery infarcts who were scanned within 2 days after stroke onset were enrolled in this study. Magnetic resonance data of ten control subjects were also examined by DT tractography. Based on the severity of aphasia at discharge, patients were divided into two groups: six patients in the aphasic group and seven in the nonaphasic group. Fractional anisotropy (FA) and number of arcuate fasciculus fibers were evaluated. Asymmetry index was calculated for both FA and number of fibers. FA values for the arcuate fasciculus fibers did not differ between hemispheres in either the patient groups or the controls. Number of arcuate fasciculus fibers exhibited a significant leftward asymmetry in the controls and the nonaphasic group but not in the aphasic group. Asymmetry index of number of fibers was significantly lower (rightward) in the aphasic group than in the nonaphasic (P = 0.015) and control (P = 0.005) groups. Loss of leftward asymmetry in number of AF fibers predicted aphasia at discharge with a sensitivity of 0.83 and specificity of 0.86. Asymmetry of arcuate fasciculus fibers by DT tractography may deserve to be assessed in acute infarction for predicting the fate of vascular aphasia. (orig.)

    Stuttering is a disorder of speech affecting millions of people around the world. Whilst the exact aetiology of stuttering remains unknown, it has been hypothesised that it is a disorder of the neural mechanisms that support speech timing. In this article, we used magnetoencephalography (MEG) to examine activity from auditory regions of the brain in stuttering and non-stuttering children aged 3-9years. For typically developing children, we found that MEG oscillations in the beta band responded to rhythmic sounds with a peak near the time of stimulus onset. In contrast, stuttering children showed an opposite phase of beta band envelope, with a trough of activity at stimulus onset. These results suggest that stuttering may result from abnormalities in predictive brain responses which are reflected in abnormal entrainment of the beta band envelope to rhythmic sounds.

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

    Full Text Available Abstract Background Recent clinical studies point to rapid and sustained clinical, cognitive, and behavioral improvement in both Alzheimer's disease and primary progressive aphasia following weekly perispinal administration of etanercept, a TNF-alpha inhibitor that acts by blocking the binding of this cytokine to its receptors. This outcome is concordant with recent basic science studies suggesting that TNF-alpha functions in vivo as a gliotransmitter that regulates synaptic function in the brain. We hypothesized that perispinal etanercept had the potential to improve verbal function in Alzheimer's disease, so we included several standarized measures of verbal ability to evaluate language skills in a clinical trial of perispinal etanercept for Alzheimer's disease. Methods This was a prospective, single-center, open-label, pilot study, in which 12 patients with mild-to-severe Alzheimer's disease were administered etanercept, 25–50 mg, weekly by perispinal administration for six months. Two additional case studies are presented. Results Two-tailed, paired t-tests were conducted comparing baseline performance to 6-month performance on all neuropsychological measures. Test batteries included the California Verbal Learning Test-Second Edition, Adult Version; Logical Memory I and II(WMS-LM-II from the Wechsler Memory Scale-Abbreviated; the Comprehensive Trail Making Test (TMT; Boston Naming Test; and letter(FAS and category verbal fluency. All measures revealed a significant effect except for the Boston Naming Test and the TMT-4, with WMS-LM-II being marginally significant at p = .05. The FAS test for letter fluency was most highly significant with a p Conclusion In combination with the previously reported results of perispinal etanercept in Alzheimer's disease and primary progressive aphasia, these results further argue that larger scale studies of this therapeutic intervention, including Phase 3 trials, are warranted in dementias.

    We have collected data from 6 PWA and two controls and anticipate enrolling 10 PWA. Whole brain analyses reveal a set of regions activated for the learning>baseline contrast across all participants that includes bilateral middle frontal gyrus (MFG, right inferior frontal gyrus (IFG, right angular gyrus and bilateral middle temporal gyrus (MTG. ROI analyses over data for two PWA and two controls demonstrate that controls produce positive percent signal change differences in the caudate (implicit system and negative percent signal change difference in the hippocampus (verbal, explicit system. In contrast, PWA show positive signal change in the hippocampus and negative percent signal change in the caudate. Conclusions PWA and controls engage a similar overall network of regions during probabilistic category learning. ROI analyses suggest, however, that PWA may exhibit a greater reliance on verbally mediated strategies, compared with a greater reliance on implicit strategies in controls. PWA with mild aphasia who have access to language, may be predisposed to utilize that language to learn, even if it is not a productive strategy.

    Full Text Available Severe word production difficulties remain one of the most challenging clinical symptoms to treat in individuals with jargon aphasia (JA. Although research has found a beneficial effect of phonological therapy in JA (e.g., FF in Bose 2013; GF in Robson et al., 1998, a lack of improvement in naming performance following this approach has also been reported (e.g., P9 in Leonard et al., 2008. Clinically, it is important to determine why some individuals with JA improve following phonological therapy when others do not. This research investigates the effect of phonological therapy on naming performance in JA and explores possible reasons for improvement or lack thereof (e.g., input/ output processing skills, ability to use and maintain cues. Methods Participant: AM, an 86 year old, English-speaking male, was 16 years post-stroke and presented with persistent, severe neologistic jargon, characterized by very high proportions of non-words and perseverations. Part 1: Effects of phonological cuing (initial phoneme vs. semantic cuing (semantically-related item on naming performance were tested on items from the Philadelphia Naming Test (Roach et al., 1996 to determine the most suitable course of therapy.

    In 1833 an accomplished 26-year-old linguist suffered a non-paralytic stroke. After he recovered, though he could utter a variety of syllables with ease, he spoke an unintelligible jargon that caused him to be mistaken as a foreigner. He was examined repeatedly over the course of a year by Jonathan Osborne (1794-1864), a Dublin physician and professor of materia medica, who found that the patient understood whatever was said to him, that he could read and write fluently, but had difficulty repeating words read to him or in reading aloud. Osborne recommended that he learn to speak English, his natural language, de novo and over 8 months measured his considerable improvement. To explain the patient's singular difficulty in repeating spoken words Osborne argued it was 'highly probable that, having been conversant with five languages, the muscular apparatus ranged among them, forming a kind of polyglot jargon [that was] wholly unintelligible' and the patient was 'unable to penetrate into and select the contents of the store according as the [words] were required'. The discrepancy between comprehension and repetition was later termed conduction aphasia. PMID:21052861

    Caplan, David; Michaud, Jennifer; Hufford, Rebecca

    2015-01-01

    Sixty-one people with aphasia (pwa) and 41 matched controls were tested for the ability to understand sentences that required the ability to process particular syntactic elements and assign particular syntactic structures. Participants paced themselves word-by-word through 20 examples of 11 spoken sentence types and indicated which of two pictures corresponded to the meaning of each sentence. Sentences were developed in pairs such that comprehension of the experimental version of a pair required an aspect of syntactic processing not required in the corresponding baseline sentence. The need for the syntactic operations required only in the experimental version was triggered at a "critical word" in the experimental sentence. Listening times for critical words in experimental sentences were compared to those for corresponding words in the corresponding baseline sentences. The results were consistent with several models of syntactic comprehension deficits in pwa: resource reduction, slowed lexical and/or syntactic processing, abnormal susceptibility to interference from thematic roles generated non-syntactically. They suggest that a previously unidentified disturbance limiting the duration of parsing and interpretation may lead to these deficits, and that this mechanism may lead to structure-specific deficits in pwa. The results thus point to more than one mechanism underlying syntactic comprehension disorders both across and within pwa. PMID:26165856

  2. Mechanisms of recovery from aphasia: evidence from serial xenon 133 cerebral blood flow studies

    International Nuclear Information System (INIS)

    In 21 patients who suffered aphasia resulting from left hemisphere ischemic infarction, the xenon 133 inhalation cerebral blood flow technique was used to measure cerebral blood flow within 3 months and 5 to 12 months after stroke. In addition to baseline measurements, cerebral blood flow measurements were also carried out while the patients were performing purposeful listening. In patients with incomplete recovery of comprehension and left posterior temporal-inferior parietal lesions, greater cerebral blood flow occurred with listening in the right inferior frontal region in the late studies than in the early studies. In patients with nearly complete recovery of comprehension and without left posterior temporal-inferior parietal lesions, early listening studies showed diffuse right hemisphere increases in cerebral blood flow. Later listening studies in this latter patient group showed greater cerebral blood flow in the left posterior temporal-inferior parietal region. The study provides evidence for participation of the right hemisphere in language comprehension in recovering aphasics, and for later return of function in left hemisphere regions that may have been functionally impaired early during recovery

    Full Text Available O artigo discute a semiologia das afasias, que teve início no século XIX com Broca e Wernicke. Não é nosso objetivo fornecer uma lista exaustiva de sintomas e síndromes para tratar do tema, já que buscamos discutir criticamente por que a semiologia das afasias ainda se baseia principalmente em perspectivas orgânicas na prática clínica e na pesquisa científica. Também discutimos as contribuições de Luria e de Jakobson para uma melhor compreensão de como a linguagem está comprometida nas afasias e como a Lingüística Moderna, sobretudo a Neurolingüística Discursiva, pode iluminar o debate. Analisamos alguns dados para ilustrar os pressupostos teóricos e metodológicos das referidas abordagens e discutimos ainda o peso excessivo que as classificações têm no contexto clínico.The article discusses the semiology of aphasias, which started being developed in the 19th century by Broca and Wernicke. We do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. We also discuss the contributions of Luria and Jakobson to a better understanding of how language is affected in aphasias and how Modern Linguistics, in special the Discursive Neurolinguistics, may enlighten the debate. We analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

    In this study, three PWA completed a computerized picture span task while an eye-tracker measured pupil dilation. As short-term memory demands (i.e., span size increased, average pupil size significantly increased in all three PWA. These data provide preliminary support for the use of pupillometry to gauge cognitive effort in PWA. A larger study of PWA and demographically-matched control participants is currently underway, allowing for analysis of change in pupil size within and between groups. Examination of cognitive effort will provide a more comprehensive understanding of the nature of linguistic and cognitive functioning in aphasia.

    Full Text Available Introduction. While the evidence for efficacy of rehabilitation of language disorders is fairly robust and conclusive (Allen, et al., 2012; Brady, et al., 2012; Kelly, Brady, & Enderby, 2010; Cherney, et al., 2008, a major limitation identified by these reviews is that the sample size of patients in each of the interventions have been modest (5-20 patients. As technology moves our field forward, we can now collect and analyze larger sets of data to validate theories of rehabilitation. As a first step, we report data from a recently completed study examining the effectiveness of software platform (Constant Therapy to deliver, monitor and analyze treatment for individuals with aphasia (Des Roches et al., 2015. Methods. Fifty one individuals with language and cognitive deficits were administered standardized tests (Western Aphasia Battery, Boston Naming Test, Pyramids and Palm Trees, and Cognitive Linguistic Quick Test prior to initiation and following completion of therapy. Forty-two experimental patients used the iPad-based therapy once a week with the clinician and up to six days a week for home practice. Nine control patients practiced therapy on the iPad once per week with the clinician only. Thirty-eight therapy tasks were divided into language and cognitive activities that were developed (Des Roches et al., 2015, 28 of these tasks included buttons that revealed a hint to assist the patient answer the item. The assigned therapy tasks were tailored to that individual’s language and cognitive impairment profile based on an initial baseline assessment. Each task was practiced until accuracy on task reached 100% on multiple occasions at which point that task was replaced with the task at the next level of difficulty. The 51 patients each completed a 10 week program leading to total of 3327 therapy sessions across patients. Analysis and Results: Mixed regression models showed that both the experimental and control groups improved but

    We report an autopsy case of progressive supranuclear palsy (PSP) that clinically showed only slowly progressive and symmetric upper motor neuron syndrome over a disease course of 12 years. A female patient initially exhibited dysarthria at the age of 65, followed by gait disturbance and dysphagia. Neurological examination at age 67 disclosed pseudobulbar palsy, spastic gait, hyperreflexia, and presence of bilateral Hoffmann and Babinski signs. However, muscle atrophy, weakness, evidence of denervation on electromyography, vertical gaze palsy, parkinsonism, gait freezing, aphasia, speech apraxia, or dementia was not noted throughout the course. She was clinically diagnosed as having motor neuron disease consistent with so-called primary lateral sclerosis. Pathological examination disclosed histopathological features of PSP, including argyrophilic and tau-positive tufted astrocytes, neurofibrillary tangles, coiled bodies, and thread-like processes in the motor cortex and superior frontal gyrus, and to a lesser degree, in the basal ganglia and brain stem nuclei. In addition, severe fibrillary gliosis was noted in the precentral gyrus and corticospinal tract, being consistent with upper motor neuron syndrome observed in this case. No TAR-DNA binding protein 43-positive lesion, FUS pathology, Bunina body, or Lewy body-like hyaline inclusion was noted in the motor cortex or lower motor neurons. These findings suggest that when tau pathology is prominent in the motor cortex but is minimal in the basal ganglia and brain stem nuclei, a PSP case can lack all classic clinical features of PSP and show only slowly progressive upper motor syndrome, consistent with clinical picture of primary lateral sclerosis.

    Full Text Available In Neurolinguistics, the use of diagnostic tests developed in other countries can create difficulties in the interpretation of results due to cultural, demographic and linguistic differences. In a country such as Brazil, with great social contrasts, schooling exerts a powerful influence on the abilities of normal individuals. The objective of the present study was to identify the influence of schooling on the performance of normal Brazilian individuals in the Boston Diagnostic Aphasia Examination (BDAE, in order to obtain reference values for the Brazilian population. We studied 107 normal subjects ranging in age from 15 to 84 years (mean ± SD = 47.2 ± 17.6 years, with educational level ranging from 1 to 24 years (9.9 ± 4.8 years. Subjects were compared for scores obtained in the 28 subtests of the BDAE after being divided into groups according to age (15 to 30, N = 24, 31 to 50, N = 33 and 51 years or more, N = 50 and education (1 to 4, N = 26, 5 to 8, N = 17 and 9 years or more, N = 61. Subjects with 4 years or less of education performed poorer in Word Discrimination, Visual Confrontation Naming, Reading of Sentences and Paragraphs, and Primer-Level Dictation (P < 0.05. When breakdown by schooling was 8 years or less, subjects performed poorer in all subtests (P < 0.05, except Responsive Naming, Word Recognition and Word-Picture Matching. The elderly performed poorer (P < 0.05 in Complex Ideational Material, Visual Confrontation Naming, Comprehension of Oral Spelling, Written Confrontation Naming, and Sentences to Dictation. We present the reference values for the cut-off scores according to educational level.

    Diagnosing progressive primary aphasia (PPA) and its variants is of great clinical importance, and fluorodeoxyglucose (FDG) positron emission tomography (PET) may be a useful diagnostic technique. The purpose of this study was to evaluate interobserver variability in the interpretation of FDG PET images in PPA as well as the diagnostic sensitivity and specificity of the technique. We also aimed to compare visual and statistical analyses of these images. There were 10 raters who analysed 44 FDG PET scans from 33 PPA patients and 11 controls. Five raters analysed the images visually, while the other five used maps created using Statistical Parametric Mapping software. Two spatial normalization procedures were performed: global mean normalization and cerebellar normalization. Clinical diagnosis was considered the gold standard. Inter-rater concordance was moderate for visual analysis (Fleiss' kappa 0.568) and substantial for statistical analysis (kappa 0.756-0.881). Agreement was good for all three variants of PPA except for the nonfluent/agrammatic variant studied with visual analysis. The sensitivity and specificity of each rater's diagnosis of PPA was high, averaging 87.8 and 89.9 % for visual analysis and 96.9 and 90.9 % for statistical analysis using global mean normalization, respectively. In cerebellar normalization, sensitivity was 88.9 % and specificity 100 %. FDG PET demonstrated high diagnostic accuracy for the diagnosis of PPA and its variants. Inter-rater concordance was higher for statistical analysis, especially for the nonfluent/agrammatic variant. These data support the use of FDG PET to evaluate patients with PPA and show that statistical analysis methods are particularly useful for identifying the nonfluent/agrammatic variant of PPA.

    Beta-amyloid (Aβ) deposition can be observed in primary progressive aphasia (PPA) and progressive apraxia of speech (PAOS). While it is typically associated with logopenic PPA, there are exceptions that make predicting Aβ status challenging based on clinical diagnosis alone. We aimed to determine whether MRI regional volumes or clinical data could help predict Aβ deposition. One hundred and thirty-nine PPA (n = 97; 15 agrammatic, 53 logopenic, 13 semantic and 16 unclassified) and PAOS (n = 42) subjects were prospectively recruited into a cross-sectional study and underwent speech/language assessments, 3.0 T MRI and C11-Pittsburgh Compound B PET. The presence of Aβ was determined using a 1.5 SUVR cut-point. Atlas-based parcellation was used to calculate gray matter volumes of 42 regions-of-interest across the brain. Penalized binary logistic regression was utilized to determine what combination of MRI regions, and what combination of speech and language tests, best predicts Aβ (+) status. The optimal MRI model and optimal clinical model both performed comparably in their ability to accurately classify subjects according to Aβ status. MRI accurately classified 81% of subjects using 14 regions. Small left superior temporal and inferior parietal volumes and large left Broca's area volumes were particularly predictive of Aβ (+) status. Clinical scores accurately classified 83% of subjects using 12 tests. Phonological errors and repetition deficits, and absence of agrammatism and motor speech deficits were particularly predictive of Aβ (+) status. In comparison, clinical diagnosis was able to accurately classify 89% of subjects. However, the MRI model performed well in predicting Aβ deposition in unclassified PPA. Clinical diagnosis provides optimum prediction of Aβ status at the group level, although regional MRI measurements and speech and language testing also performed well and could have advantages in predicting Aβ status in unclassified PPA subjects

    * [ ] Indicates prosodic contour Methods: Twenty-four healthy college-age control participants (YNCs and ten adults with a Broca’s aphasia participated in this study. Each sentence was presented aurally to the participants over headphones. ERP Data Recording & Analysis. ERPs were recorded from 32-electrode sites across the scalp according to the 10-20 system. ERPs were averaged (100ms prestimulus baseline from artifact free trials time-locked to critical words (i.e., the point of disambiguation “pleased” in the prosodic comparison, and the NP “the song”/”the beer” in the semantic comparison. Mean amplitudes were calculated in two windows: 300-500ms for the N400 effects and 500-1000ms for the P600 effects. Results: The data from our YNCs revealed a biphasic N400-P600 complex in the prosody comparison (Figure 1A. We also found an N400 effect immediately at the NP in the incongruent relative to congruent thematic fit comparison. For the prosodic comparison in the PWA group, a delayed N400 effect was found one word downstream relative to the YNC data in the prosody comparison (Figure 1B. Additionally, an N400 effect was observed in the thematic fit comparison. Discussion: The results suggests that PWA possess a delayed sensitivity to prosodic cues, which then may affect their ability to recover from misanalysis from an incorrect parse. The results also indicate that PWA are sensitive to thematic fit information and have the capacity to process this information similarly to YNCs.

  17. The Role of Executive Function in the Semantic Comprehension Deficits of Stroke Aphasia and Semantic Dementia

    2015-05-01

    Results from 5 SD patients and 4 SA patients in our ongoing study suggest similar patterns of impairment on both semantic and executive function tasks for both patient groups. Both showed multi-modal semantic deficits via poor performance on at least 3 out of 5 semantic tasks tapping different modalities. Also, SA and SD patients showed no difference in consistency across semantic tasks (see Fig. 1a & b. Both groups also showed consistently poor performance on trail-making and verbal Stroop tasks compared to controls (see Figs. 1c & 1d. SD patients seem to be less impaired on both span measures (word span range: 2.17 – 4.43; digit span: 3.17 – 5.5 than SA patients (word span range: 1.63 – 3.75; digit span: 1.17 – 4.17, and performance was variable for both groups on non-verbal Stroop and picture-word interference. SD patients found many executive tasks too difficult to understand, which may be the reason for limited prior data for them on EF tasks.. These findings suggest that the use of syndrome categories like semantic dementia and comprehension-impaired stroke aphasia are not useful in distinguishing between storage and access deficits. Patients classified as having SD seem as likely as SA patients to have certain kinds of executive deficits and SA patients may be as likely as SD patients to show consistency across semantic tasks. The results imply that some other behavioral or neuroanatomical basis rather than syndrome classification should be used to address the hypothesized separation of storage vs. control aspects of semantic memory.

    Conduction aphasia is a language disorder characterized by frequent speech errors, impaired verbatim repetition, a deficit in phonological short-term memory, and naming difficulties in the presence of otherwise fluent and grammatical speech output. While traditional models of conduction aphasia have typically implicated white matter pathways, recent advances in lesions reconstruction methodology applied to groups of patients have implicated left temporoparietal zones. Parallel work using functional magnetic resonance imaging (fMRI) has pinpointed a region in the posterior most portion of the left planum temporale, area Spt, which is critical for phonological working memory. Here we show that the region of maximal lesion overlap in a sample of 14 patients with conduction aphasia perfectly circumscribes area Spt, as defined in an aggregate fMRI analysis of 105 subjects performing a phonological working memory task. We provide a review of the evidence supporting the idea that Spt is an interface site for the integration of sensory and vocal tract-related motor representations of complex sound sequences, such as speech and music and show how the symptoms of conduction aphasia can be explained by damage to this system.

    We present a case of transcortical mixed aphasia caused by a cerebral embolism. A 77-year-old right-handed man was admitted to our hospital with speech disturbance and a right hemianopia. His spontaneous speech was remarkably reduced, and object naming, word fluency, comprehension, reading and writing were all severely disturbed. However, repetition of phonemes and sentences and reading aloud were fully preserved. Although magnetic resonance imaging (MRI) showed cerebral infarcts in the left frontal and parieto-occipital lobe which included the inferior frontal gyrus and angular gyrus, single photon emission CT revealed a wider area of low perfusion over the entire left hemisphere except for part of the left perisylvian language areas. The amytal (Wada) test, which was performed via the left internal carotid artery, revealed that the left hemisphere was dominant for language. Hence, it appears that transcortical mixed aphasia may be caused by the isolation of perisylvian speech areas, even if there is a lesion in the inferior frontal gyrus, due to disconnection from surrounding areas.

    NG is an architect who suffered a left occipital-parietal hemorrhage cerebral vascular accident (CVA) in 2000, resulting in aphasia of Wernicke and conduction types. He was characterized with fluent paraphasic speech, decreased repetition, and impaired object naming. Comprehension was relatively preserved but reading and writing were severely compromised, as well as his auditory working memory. Despite a grim prognosis he underwent intensive aphasia therapy, lasting from 2001 to 2010, at the Center for Cognitive Rehabilitation of the Brain Injured at the Feuerstein Institute. The tailored-made interventions, applied in NG's therapy, were based upon the implementation of the principles of the Structural Mediated Learning Experience (MLE) and the Feuerstein Instrumental Enrichment (FIE) Program, to optimize his rehabilitation. As a result NG improved in most of his impaired linguistic capacities, attested by the results of neuropsychological and linguistic assessments performed throughout the years. More importantly, he was able to manage again his daily functions at a high level, and to resume his occupational role as an architect, a role which he holds to this day. PMID:27341358

Um dos diagnósticos diferenciais de doenças neurológicas é o transtorno conversivo, cuja característica principal é a presença de sintomas afetando funções motoras ou sensoriais, que sugerem desordem clínica ou neurológica, porém sem doença orgânica subjacente que explique o quadro. RELATO DE CASO: Os autores relatam o caso de uma paciente de 23 anos com apresentação clínica atípica de acidente vascular cerebral, afasia global sem hemiparesia, que foi inicialmente diagnosticada como transtorno psiquiátrico pelo serviço de clínica médica de emergência. CONCLUSÃO: Certas apresentações neurológicas podem ser interpretadas como transtorno conversivo pelas similaridades clínicas entre as duas desordens, raridade do quadro clínico, pela presença de sintomatologia psiquiátrica e fatores psicossociais nos pacientes neurológicos. Mesmo com apresentações neurológicas atípicas e sintomas psiquiátricos, pacientes com quadro sugestivo de transtorno conversivo devem ser sempre investigados de forma interdisciplinar.BACKGROUND: The neurologic and psychiatric diagnosis in emergency settings are difficult tasks and require interdisciplinary effort.

CASE REPORT: We present a 23 year-old-woman with an atypical clinical presentation of stroke: global aphasia without hemiparesis. This patient was initially diagnosed with conversion disorder by the internal medicine service in the emergency room. CONCLUSION: Some rare neurologic diseases can be interpreted as conversive disorders due to some reasons

  12. The Brain Network of Naming: A Lesson from Primary Progressive Aphasia.

    Directory of Open Access Journals (Sweden)

    Full Text Available Word finding depends on the processing of semantic and lexical information, and it involves an intermediate level for mapping semantic-to-lexical information which also subserves lexical-to-semantic mapping during word comprehension. However, the brain regions implementing these components are still controversial and have not been clarified via a comprehensive lesion model encompassing the whole range of language-related cortices. Primary progressive aphasia (PPA, for which anomia is thought to be the most common sign, provides such a model, but the exploration of cortical areas impacting naming in its three main variants and the underlying processing mechanisms is still lacking.We addressed this double issue, related to language structure and PPA, with thirty patients (11 semantic, 12 logopenic, 7 agrammatic variant using a picture-naming task and voxel-based morphometry for anatomo-functional correlation. First, we analyzed correlations for each of the three variants to identify the regions impacting naming in PPA and to disentangle the core regions of word finding. We then combined the three variants and correlation analyses for naming (semantic-to-lexical mapping and single-word comprehension (lexical-to-semantic mapping, predicting an overlap zone corresponding to a bidirectional lexical-semantic hub.Our results showed that superior portions of the left temporal pole and left posterior temporal cortices impact semantic and lexical naming mechanisms in semantic and logopenic PPA, respectively. In agrammatic PPA naming deficits were rare, and did not correlate with any cortical region. Combined analyses revealed a cortical overlap zone in superior/middle mid-temporal cortices, distinct from the two former regions, impacting bidirectional binding of lexical and semantic information. Altogether, our findings indicate that lexical/semantic word processing depends on an anterior-posterior axis within lateral-temporal cortices, including an

    Differentiation of logopenic (lvPPA) and nonfluent/agrammatic (nfvPPA) variants of Primary Progressive Aphasia is important yet remains challenging since it hinges on expert based evaluation of speech and language production. In this study acoustic measures of speech in conjunction with voxel-based morphometry were used to determine the success of the measures as an adjunct to diagnosis and to explore the neural basis of apraxia of speech in nfvPPA. Forty-one patients (21 lvPPA, 20 nfvPPA) were recruited from a consecutive sample with suspected frontotemporal dementia. Patients were diagnosed using the current gold-standard of expert perceptual judgment, based on presence/absence of particular speech features during speaking tasks. Seventeen healthy age-matched adults served as controls. MRI scans were available for 11 control and 37 PPA cases; 23 of the PPA cases underwent amyloid ligand PET imaging. Measures, corresponding to perceptual features of apraxia of speech, were periods of silence during reading and relative vowel duration and intensity in polysyllable word repetition. Discriminant function analyses revealed that a measure of relative vowel duration differentiated nfvPPA cases from both control and lvPPA cases (r(2) = 0.47) with 88% agreement with expert judgment of presence of apraxia of speech in nfvPPA cases. VBM analysis showed that relative vowel duration covaried with grey matter intensity in areas critical for speech motor planning and programming: precentral gyrus, supplementary motor area and inferior frontal gyrus bilaterally, only affected in the nfvPPA group. This bilateral involvement of frontal speech networks in nfvPPA potentially affects access to compensatory mechanisms involving right hemisphere homologues. Measures of silences during reading also discriminated the PPA and control groups, but did not increase predictive accuracy. Findings suggest that a measure of relative vowel duration from of a polysyllable word repetition task

    Full Text Available Small clinical trials have reported that low-frequency repetitive transcranial magnetic stimulation (rTMS might improve language recovery in patients with aphasia after stroke. However, no systematic reviews or meta-analyses studies have investigated the effect of rTMS on aphasia. The objective of this study was to perform a meta-analysis of studies that explored the effects of low-frequency rTMS on aphasia in stroke patients.We searched PubMed, CENTRAL, Embase, CINAHL, ScienceDirect, and Journals@Ovid for randomized controlled trials published between January 1965 and October 2013 using the keywords "aphasia OR language disorders OR anomia OR linguistic disorders AND repetitive transcranial magnetic stimulation OR rTMS". We used fixed- and random-effects models to estimate the standardized mean difference (SMD and a 95% CI for the language outcomes.Seven eligible studies involving 160 stroke patients were identified in this meta-analysis. A significant effect size of 1.26 was found for the language outcome severity of impairment (95% CI = 0.80 to 1.71 without heterogeneity (I2 = 0%, P = 0.44. Further analyses demonstrated prominent effects for the naming subtest (SMD = 0.52, 95% CI = 0.18 to 0.87, repetition (SMD = 0.54, 95% CI = 0.16 to 0.92, writing (SMD = 0.70, 95% CI = 0.19 to 1.22, and comprehension (the Token test: SMD = 0.58, 95% CI = 0.07 to 1.09 without heterogeneity (I2 = 0%. The SMD of AAT and BDAE comprehension subtests was 0.32 (95% CI = -0.08 to 0.72 with moderate heterogeneity (I2 = 32%,P = 0.22. The effect size did not change significantly even when any one trial was eliminated. None of the patients from the 7 included articles reported adverse effects from rTMS.Low-frequency rTMS with a 90% resting motor threshold that targets the triangular part of the right inferior frontal gyrus (IFG has a positive effect on language recovery in patients with aphasia following

    2015-12-01

    Consensual recommendations for the diagnostic criteria of three variants of primary progressive aphasia (PPA) were published in 2011. Since their publication, these recommendations were the object of criticism, which has recently led to the proposition of their revision. This article gives a description of the criteria that preceded the consensual criteria currently in use, and presents the different limits and controversies regarding the description of each PPA variant's language profile. These controversies will be examined in terms of the description of each variant's central manifestations, their differential diagnosis, the links between each clinical entity and its underlying pathology, and the evolution of the language profile. Lastly, this article offers perspectives regarding language evaluation in PPA that have several implications for clinical practice and research. PMID:26707562

    Full Text Available INTRODUCTION A growing body of evidence suggests people with aphasia (PWA can have impairments to cognitive functions such as attention, working memory and executive functions.(1-5 Such cognitive impairments have been shown to negatively affect the decision-making (DM abilities adults with neurological damage. (6,7 However, little is known about DM abilities of PWA.(8 Pupillometry is “the measurement of changes in pupil diameter”.(9;p.1 Researchers have reported a positive relationship between processing load and phasic pupil size (i.e., as processing load increases, pupil size increases.(10 Thus pupillometry has the potential to be a useful tool for investigating processing load during DM in PWA. AIMS The primary aim of this study was to establish the feasibility of using pupillometry during a non-verbal DM task with PWA. The secondary aim was to explore non-verbal DM performance in PWA and determine the relationship between DM performance and processing load using pupillometry. METHOD DESIGN. A single-subject case-study design with two participants was used in this study. PARTICIPANTS. Two adult males with anomic aphasia participated in this study. Participants were matched for age and education. Both participants were independent, able to drive, and had legal autonomy. MEASURES. PERFORMANCE ON A DM TASK. We used a computerized risk-taking card game called the Iowa Gambling Task (IGT as our non-verbal DM task.(11 In the IGT, participants made 100 selections (via eye gaze from four decks of cards presented on the computer screen with the goal of maximizing their overall hypothetical monetary gain. PROCESSING LOAD. The EyeLink 1000+ eye tracking system was used to collect pupil size measures while participants deliberated before each deck selection during the IGT. For this analysis, we calculated change in pupil size as a measure of processing load. RESULTS P1. P1 made increasingly advantageous decisions as the task progressed (Fig.1. When

    A 77 year old right handed male was blind since the age of 2. He presented with an infarction involving the territory of the left middle cerebral artery involving the temporal and the inferior parietal lobes. He had learned to read and write language as well as read and write music in braille, ultimately becoming a famous organist and composer. There were no motor or sensory deficits. Wernicke's aphasia with jargonaphasia, major difficulty in repetition, anomia and a significant comprehension deficit without word deafness was present; verbal alexia and agraphia in braille were also present. There was no evidence of amusia. He could execute in an exemplary fashion pieces of music for the organ in his repertory as well as improvise. All his musical capabilities: transposition, modulation, harmony, rythm, were preserved. The musical notation in braille remained intact: he could read by touch and play unfamiliar scores, he could also read and sing the musical notes, he could copy and write a score. Nine months after the stroke his aphasia remained unchanged. Nevertheless he composed pieces for the organ which were published. Such data highly suggest the independence of linguistic and musical competences, defined as the analysis and organization of sounds according to the rules of music. This independence in an extremely talented musician leads to a discussion of the role of the right hemisphere in the anatomical-functional processes at the origin of musical competence. The use of braille in which the same constellations of dots correspond either to letters of the alphabet or musical notes supports the independence between language and music. PMID:3616363

Arranca de la función simbólica, que establece la distinción y el nexo entre significante y significado. Se establece, a grandes rasgos, una clasificación neurolingüística de las afasias, rechazando las expresiones inadecuadas de sensitiva o sensorial y motora. Se insiste particularmente aquí sobre la cuestión de la "repetición" en la semiología afásica, tanto en lo que se refiere a su pérdida como a su "exaltación". Ello conduce a una revisión de la mal llamada afasia "de conducción" y del "transcorticalismo".Aphasias are language pathologies, therefore the acquaintance of its structure is required for proper understanding.

  6. Fast self paced listening times in syntactic comprehension is aphasia -- implications for deficits

    Full Text Available Sixty one people with aphasia (pwa and forty one matched controls were tested for the ability to understand sentences that required the ability to assign particular syntactic structures. Participants paced themselves word-by-word through twenty examples of eleven spoken sentence types and indicated which of two pictures corresponded to the meaning of each sentence. Sentences were developed in pairs such that comprehension of the experimental version of a pair required an aspect of syntactic processing not required in the corresponding baseline sentence. The need for the syntactic operations required only in the experimental version was triggered at a “critical word” in the experimental sentence. Listening times for critical words in experimental sentences were compared to those for corresponding words in the corresponding baseline sentences. We adjusted self paced listening times for word duration by subtracting word durations from tag-to-tag self paced listening times to correct for word duration, yielding what we have previously called “corrected listening times.” Corrected listening times above ceiling (10,000 msec for sentence-final words and 5,000 msec for all other words were discarded. For controls, this led to 0.2% of data being discarded and for PWAs 2.2% were discarded. Corrected listening times that were more than 3 standard deviations above or below the mean for that sentence type for each subject were adjusted either down to the upper limit or up to the lower limit of the 3SD range (not discarded. For accurate sentences, 1.7% of the control data were adjusted and 1.8% of the aphasic data were adjusted. For inaccurate sentences, 10% of the corrected listening times were adjusted for controls and 3.3% for aphasics. Our interest is in incremental parsing and interpretation. The measure we used of this process was the residual of a regression of corrected self paced listening times for critical words in experimental sentences

    2015-05-01

    Full Text Available Over the last decade, a number of large-scale networks in the human cortex that support high-level cognition have been identified. Here, we focus on two of these networks: the fronto-temporal language network (e.g., Fedorenko et al., 2010, and the fronto-parietal “multiple demand (MD” network (e.g., Duncan, 2010. These two networks are clearly distinct from one another: first, their respective regions show distinct functional profiles, with language regions showing selective responses to language stimuli (Fedorenko et al., 2011; Monti et al., 2012 and MD regions showing domain-general responses to cognitive effort across a wide range of tasks (Duncan & Owen, 2001; Fedorenko et al., 2013. Second, during “rest” and cognitive processing, each network shows strong activity synchronization among its constituent regions, whereas regions across the two networks are not synchronized (Blank et al., 2014; Lee et al., 2012; Mantini et al., 2013. In the current study, we examined how these functional characteristics of the two networks were affected following aphasia-inducing strokes. In particular, we asked whether damage to the language network would alter the involvement of the MD network in linguistic processing, and whether such damage would alter the patterns of synchronization across the two networks. Four male individuals with aphasia (age: M=53, having suffered a single left MCA CVA, were scanned in fMRI on two paradigms that enable basic functional characterization of language and MD regions: (i a language localizer task, where they passively read sentences and sequences of pseudowords (Fedorenko et al., 2010; and (ii a spatial working memory task, where they had to remember fewer (easy or more (hard locations in a grid (Fedorenko et al., 2013.

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    Several studies have already shown that transcranial direct current stimulation (tDCS) is a useful tool for enhancing recovery in aphasia. However, no reports to date have investigated functional connectivity changes on cortical activity because of tDCS language treatment. Here, nine aphasic persons with articulatory disorders underwent an intensive language therapy in two different conditions: bilateral anodic stimulation over the left Broca's area and cathodic contralesional stimulation over the right homologue of Broca's area and a sham condition. The language treatment lasted 3 weeks (Monday to Friday, 15 sessions). In all patients, language measures were collected before (T0) and at the end of treatment (T15). Before and after each treatment condition (real vs. sham), each participant underwent a resting-state fMRI study. Results showed that, after real stimulation, patients exhibited the greatest recovery not only in terms of better accuracy in articulating the treated stimuli but also for untreated items on different tasks of the language test. Moreover, although after the sham condition connectivity changes were confined to the right brain hemisphere, real stimulation yielded to stronger functional connectivity increase in the left hemisphere. In conclusion, our data provide converging evidence from behavioral and functional imaging data that bilateral tDCS determines functional connectivity changes within the lesioned hemisphere, enhancing the language recovery process in stroke patients.

    2004-05-01

    Primary Progressive Aphasia (PPA) is a clinical dementia syndrome characterized by the gradual dissolution of language without impairment of other cognitive domains for at least the first 2 years of illness (M.-M. Mesulam, 1982, 2001). It is difficult to demonstrate the integrity of nonlanguage domains in PPA because most neuropsychological tests of memory, reasoning, and attention require language competence for their performance. In the present study, reasoning and cognitive flexibility were tested nonverbally in patients with PPA using a modified ten-item version of the Visual Verbal Test (Feldman & Drasgow, 1959). This test measures the ability to detect similarities among objects and to sort a single set of objects according to two different principles. The performance of PPA patients (n = 20) was compared with that of patients with dementia of the Alzheimer type (AD) (n = 20), patients with the comportmental/executive dysfunction variant of frontotemporal dementia (FTD) (n = 16), and cognitively intact controls (n = 20). Patients with PPA and controls performed similarly, detecting commonalities among objects and shifting from one sorting principle to another. In contrast, both AD and FTD subjects were significantly impaired on both measures. These results provide evidence of preserved reasoning in PPA, further differentiating this syndrome from other behaviorally focal dementia syndromes. PMID:15512925

    Full Text Available Hematoma alone is the most common vascular complication reported after anterior cervical decompression and fusion (ACDF. We present this case to report the occurrence of postoperative cervical hematoma complicated by ipsilateral carotid thrombosis and aphasia after an uncomplicated C4–6 ACDF. This is a case of a 65-year-old woman who underwent revision fusions of the C4-5 and C6-7 levels complicated by postoperative cervical hematoma and carotid thrombosis. The patient's history, clinical examination, imaging findings, and treatment are reported. The revision fusions were performed and deemed routine. Approximately eight hours later 200 mL of blood was evacuated from a postoperative cervical hematoma. The patient became unresponsive and disoriented a few hours after evacuating the hematoma. Computed tomography and magnetic resonance imaging of the brain were normal, but magnetic resonance angiography demonstrated total occlusion of the left carotid artery. Thrombectomy was performed and the patient was discharged without residual deficits. At the latest followup she is fully functional and asymptomatic in her neck. We suggest, after evacuating a cervical hematoma, an evaluation of the carotids be made with MRA or cerebral angiography, as this may demonstrate a clot before the patient develops symptoms.

    Speech-language pathologists' scope of practice is currently unclear in relation to their contribution to the multi-disciplinary assessment of decision-making capacity for clients with aphasia and related neurogenic communication disorders. The primary aim of the current research study was to investigate the common practices of speech-language pathologists involved in assessments of decision-making capacity. The study was completed through the use of an online survey. There were 51 of 59 respondents who indicated involvement in evaluations of decision-making. Involvement in this kind of assessment was most commonly reported by speech-language pathologists working in inpatient acute and rehabilitation settings. Respondents reported using a variety of formal and informal assessment methods in their contributions to capacity assessment. Discussion with multidisciplinary team members was reported to have the greatest influence on their recommendations. Speech-language pathologists reported that they were dissatisfied with current protocols for capacity assessments in their workplace and indicated they would benefit from further education and training in this area. The findings of this study are discussed in light of their implications for speech-language pathology practice. PMID:24400775

    Full Text Available Abstract Background Aphasia is a severely disabling condition occurring in 20 to 25% of stroke patients. Most patients with aphasia due to stroke receive speech and language therapy. Methodologically sound randomised controlled trials investigating the effect of specific interventions for patients with aphasia following stroke are scarce. The currently available evidence suggests that intensive speech and language therapy is beneficial for restoration of communication, but the optimal timing of treatment is as yet unclear. In the Rotterdam Aphasia Therapy Study-3 we aim to test the hypothesis that patients with aphasia due to stroke benefit more from early intensive cognitive-linguistic therapy than from deferred regular language therapy. Methods/design In a single blinded, multicentre, randomised controlled trial, 150 patients with first ever aphasia due to stroke will be randomised within two weeks after stroke to either early intensive cognitive-linguistic therapy (Group A or deferred regular therapy (Group B. Group A will start as soon as possible, at the latest two weeks after stroke, with a four week period of one hour a day treatment with cognitive-linguistic therapy. In Group B professional speech and language therapy is deferred for four weeks. After this period, patients will follow the conventional procedure of speech and language therapy. Participants will be tested with an extensive linguistic test battery at four weeks, three months and six months after inclusion. Primary outcome measure is the difference in score between the two treatment groups on the Amsterdam-Nijmegen Everyday Language Test, a measure of everyday verbal communication, four weeks after randomisation.

    Full Text Available We report a patient with non-fluent Primary Progressive Aphasia who was premorbidly literate in two alphabetic scripts, Hungarian (L1 and English (L2. Testing was performed over a two-year period to assess the impact of progressive illness on oral reading and repetition of single words. Results showed significant decline in oral reading in both languages, and an effect of language status in favour of oral reading in L1. Phonological complexity was a significant predictor of oral reading decline in both languages. Of interest, we observed an effect of language status on task performance whereby repetition was better in L2 than L1 but oral reading was better in L1 than L2. We conclude that language status has an effect on repetition and oral reading abilities for bilingual speakers with non-fluent Primary Progressive Aphasia.

    Diagnostic distinction of primary progressive aphasias (PPA) remains challenging, in particular for the logopenic (lvPPA) and nonfluent/agrammatic (naPPA) variants. Recent findings highlight that episodic memory deficits appear to discriminate these PPA variants from each other, as only lvPPA perform poorly on these tasks while having underlying amyloid pathology similar to that seen in amnestic dementias like Alzheimer's disease (AD). Most memory tests are, however, language based and thus potentially confounded by the prevalent language deficits in PPA. The current study investigated this issue across PPA variants by contrasting verbal and non-verbal episodic memory measures while controlling for their performance on a language subtest of a general cognitive screen. A total of 203 participants were included (25 lvPPA; 29 naPPA; 59 AD; 90 controls) and underwent extensive verbal and non-verbal episodic memory testing, with a subset of patients (n = 45) with confirmed amyloid profiles as assessed by Pittsburgh Compound B and PET. The most powerful discriminator between naPPA and lvPPA patients was a non-verbal recall measure (Rey Complex Figure delayed recall), with 81% of PPA patients classified correctly at presentation. Importantly, AD and lvPPA patients performed comparably on this measure, further highlighting the importance of underlying amyloid pathology in episodic memory profiles. The findings demonstrate that non-verbal recall emerges as the best discriminator of lvPPA and naPPA when controlling for language deficits in high load amyloid PPA cases. PMID:26890745

    Producing a word requires selecting among a set of similar alternatives. When many semantically related items become activated, the difficulty of the selection process is increased. Experiment 1 tested naming of items with either multiple synonymous labels ("Alternate Names," e.g., gift/present) or closely semantically related but non-equivalent responses ("Near Semantic Neighbors," e.g., jam/jelly). Picture naming was fastest and most accurate for pictures with only one label ("High Name Agreement"), slower and less accurate in the Alternate Names condition, and slowest and least accurate in the Near Semantic Neighbors condition. These results suggest that selection mechanisms in picture naming operate at two distinct levels of processing: selecting between similar but non-equivalent names requires two selection processes (semantic and lexical), whereas selecting among equivalent names only requires one selection at the lexical level. Experiment 2 examined how these selection mechanisms are affected by normal aging and found that older adults had significantly more difficulty in the Near Semantic Neighbors condition, but not in the Alternate Names condition. This suggests that aging affects semantic processing and selection more strongly than it affects lexical selection. Experiment 3 examined the role of the left inferior frontal gyrus (LIFG) in these selection processes by testing individuals with aphasia secondary to stroke lesions that either affected the LIFG or spared it. Surprisingly, there was no interaction between condition and lesion group: the presence of LIFG damage was not associated with substantively worse naming performance for pictures with multiple acceptable labels. These results are not consistent with a simple view of LIFG as the locus of lexical selection and suggest a more nuanced view of the neural basis of lexical and semantic selection. PMID:27458393

    Chronic inflammation is the basis of various chronic illnesses including cancer and vascular diseases. However, much has yet to be learned how inflammation becomes chronic. Prostaglandins (PGs) are well established as mediators of acute inflammation, and recent studies in experimental animals have provided evidence that they also function in transition to and maintenance of chronic inflammation. One role PGs play in such processes is amplification of cytokine signaling. As such, PGs can facil...

    Full Text Available Primary progressive aphasia (PPA is an intriguing syndrome, showing some peculiar aspects that differentiate it from classical aphasic pictures caused by focal cerebral lesions or dementia. The slow and progressive deterioration of language occurring in these cases provides an interesting model to better understand the mechanisms involved in the linguistic process. We describe clinical and neuroimaging aspects found in 16 cases of PPA. Our patients underwent language and neuropsychological evaluation, magnetic resonance imaging (MRI and single photon emission computerized tomography (SPECT. We observed a clear distinction in oral expression patterns; patients were classified as fluent and nonfluent. Anomia was the earliest and most evident symptom in both groups. Neuroimaging pointed to SPECT as a valuable instrument in guiding the differential diagnosis, as well as in making useful clinical and anatomical correlations. This report and a comparison to literature are an attempt to contribute to a better understanding of PPA.A afasia progressiva primária (APP é uma síndrome que tem despertado grande interesse devido a aspectos particulares que a diferenciam das afasias clássicas (secundárias a lesões cerebrais focais e dos quadros demenciais.

    2015-09-01

    Executive control is impaired from the early stages of Alzheimer's Disease (AD) and this produces deregulated semantic cognition (Corbett, Jefferies, Burns, & Lambon Ralph, ; Perry, Watson, & Hodges, ). While control deficits should affect semantic retrieval across all modalities, previous studies have typically focused on verbal semantic tasks. Even when non-verbal semantic tasks have been used, these have typically employed simple picture-matching tasks, which may be influenced by abnormalities in covert naming. Therefore, in the present study, we examined 10 patients with AD on a battery of object-use tasks, in order to advance our understanding of the origins of non-verbal semantic deficits in this population. The AD patients' deficits were contrasted with previously published performance on the same tasks within two additional groups of patients, displaying either semantic degradation (semantic dementia) or deregulation of semantic retrieval (semantic aphasia; Corbett, Jefferies, Ehsan, & Lambon Ralph, ). While overall accuracy was comparable to the scores in both other groups, the AD patients' object-use impairment most closely resembled that observed in SA; they exhibited poorer performance on comprehension tasks that placed strong demands on executive control. A similar pattern was observed in the expressive domain: the AD and SA groups were relatively good at straightforward object use compared to executively demanding, mechanical puzzles. Error types also differed: while all patients omitted essential actions, the SA and AD groups' demonstrations also featured unrelated intrusions. An association between AD patients' object use and their scores on standard executive measures suggested that control deficits contributed to their non-verbal semantic deficits. Moreover, in a task specifically designed to manipulate executive demand, patients with AD (and SA) exhibited difficulty in thinking flexibly about the non-canonical uses of everyday objects, especially

  15. Cognitive grammar and aphasic discourse.

    Manning, Molly; Franklin, Sue

    2016-01-01

    In cognitive grammar (CG), there is no clear division between language and other cognitive processes; all linguistic form is conceptually meaningful. In this pilot study, a CG approach was applied to investigate whether people with aphasia (PWA) have cognitive linguistic difficulty not predicted from traditional, componential models of aphasia. Narrative samples from 22 PWA (6 fluent, 16 non-fluent) were compared with samples from 10 participants without aphasia. Between-group differences were tested statistically. PWA had significant difficulty with temporal sequencing, suggesting problems that are not uniquely linguistic. For some, these problems were doubly dissociated with naming, used as a general measure of severity, which indicates that cognitive linguistic difficulties are not linked with more widespread brain damage. Further investigation may lead to a richer account of aphasia in line with contemporary linguistics and cognitive science approaches. PMID:26900999

    Otitis media occurs along a continuum. For example, otitis media with effusion characterized by fluid pathology can lead to chronic otitis media plus chronic mastoiditis, characterized by the presence of intractable tissue pathology such as cholesteatoma, cholesterol granuloma or granulation tissue. The literature defines chronic otitis media as having a tympanic membrane perforation and otorrhea. Amongst many other sequelae, which can result from the continuum, an important common one is chronic silent otitis media. This overlooked entity which includes pathology beneath an intact tympanic membrane is commonly seen in our human temporal bone laboratory and in patients. The clinical pathological correlates of this important disease are discussed herein. PMID:12021496

  1. “I know it but I can’t say it”: Clarifying the subjective experience of inner speech in aphasia

    Directory of Open Access Journals (Sweden)

    Mackenzie Fama

    2014-04-01

    Overall, we have demonstrated that individuals with aphasia can describe a perceived mismatch between their inner and out loud speech. Their frequency ratings suggest that they can distinguish between different specific internal experiences of anomia, when given the opportunity to do so. These results, along with preliminary lesion-symptom mapping, further suggest that sIS shares characteristics with ToT and that both are discrete from simply recognizing an object or concept. We suggest that this difference reflects a reliance of both sIS and ToT on some level of phonological access, whereas the perception of “knowing it” relies only on semantic access. Continuing to explore subjective experiences of anomia has significant implications for future research, potentially improving our understanding and treatment of this pervasive deficit.

    2009-01-01

    Full Text Available The aim of this study was to investigate perseveration in two contexts: spontaneous language and linguistic tasks. It points toward perseveration as a theoretical linguistic conception, that is, sociointeractionist. This presupposes language activity produced in an interlocutive space and it does not neglect pragmatic aspects and contextual use of language. Four patients presenting the following types of aphasia were analyzed: motor transcortical, amnestic, semantic and sensory. The results point out different aspects between pathological perseveration and perseveration as a normal expression in the process of language activity. This study might imply another theoretical perspective of language therapy to perseveration in aphasia.O propósito deste estudo foi investigar a perseveração em dois contextos: linguagem espontânea e tarefas linguísticas. Esta pesquisa aponta para a perseveração como sendo uma concepção teórico-linguística, qual seja, sociointeracionista. Isto abrange atividade linguística produzida em um espaço interlocutivo e não negligencia aspectos pragmáticos e o uso contextual da língua. Quatro pacientes, apresentando os seguintes tipos de afasia, foram analisados: transcortical motora, amnéstica, semântica e sensorial. Os resultados apontam para diferentes aspectos entre perseveração patológica e perseveração, como expressão normal do processo de atividade de linguagem. Este estudo poderá implicar outra perspectiva teórica de terapia de linguagem na afasia.

    2013-12-01

    Full Text Available Assessment of brain-damaged subjects presenting with dissociated repetition deficits after selective injury to either the left dorsal or ventral auditory pathways can provide further insight on their respective roles in verbal repetition. We evaluated repetition performance and its neural correlates using multimodal imaging (anatomical MRI, DTI, fMRI and 18FDG-PET in a female patient with transcortical motor aphasia (TCMA and in a male patient with conduction aphasia (CA who had small contiguous but non-overlapping left perisylvian infarctions. Repetition in the TCMA patient was fully preserved except for a mild impairment in nonwords and digits, whereas the CA patient had impaired repetition of nonwords, digits and word triplet lists. Sentence repetition was impaired, but he repeated novel sentences significantly better than clichés. The TCMA patient had tissue damage and reduced metabolism in the left sensorimotor cortex and insula. DTI showed damage to the left temporo-frontal and parieto-frontal segments of the arcuate fasciculus (AF and part of the left ventral stream together with well-developed right dorsal and ventral streams, as has been reported in more than one-third of females. The CA patient had tissue damage and reduced metabolic activity in the left temporoparietal cortex with additional metabolic decrements in the left frontal lobe. DTI showed damage to the left temporo-parietal and temporo-frontal segments of the AF, but the ventral stream was spared. The direct segment of the AF in the right hemisphere was also absent with only vestigial remains of the other dorsal subcomponents present, as is often found in males. fMRI during word and nonword repetition revealed bilateral perisylvian activation in the TCMA patient suggesting recruitment of spared segments of the left dorsal stream and right dorsal stream with propagation of signals to temporal lobe structures suggesting a compensatory reallocation of resources via the ventral

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

  8. Examining Durability and Generalization Following Lexical Retrieval Treatment in an Individual with Semantic Variant of Primary Progressive Aphasia

    Directory of Open Access Journals (Sweden)

    Kindle Rising

    2015-05-01

    Full Text Available Introduction: The Semantic Variant of Primary Progressive Aphasia (PPAsv is characterized by marked anomia, even in the earliest stages of the disease1. Despite the progressive nature of the disorder, there is evidence that lexical retrieval may improve following behavioral treatment2-4. Most approaches focus on stimulation treatment targeting specific lexical items (e.g., verbal repetition paired with written words, but outcomes are typically item specific with limited generalization, and maintenance has not been well characterized2-4. Treatment approaches that attempt to engage relatively spared cognitive processes (phonology, orthography, episodic memory in addition to maximizing residual semantic abilities may contribute to better generalization and durability2-5. Henry and colleagues (20135 described one such approach, which contributed to positive treatment outcomes and generalization in an individual with PPAsv. Additional treatment was conducted with this individual two years after the first course of therapy. Here we report response to treatment at each time point, and describe performance following various intervals without treatment. Method: SV was a 60-year-old man who described increased word finding difficulties over a 1.5-year period. Comprehensive assessment revealed relatively isolated language impairment characterized by severely impaired lexical retrieval. Performance on semantic tasks was significantly below the normal range. An MRI revealed notable atrophy of the left anterior temporal lobe, consistent with PPAsv. SV participated in a two-phase lexical retrieval treatment: The Arizona Lexical Retrieval Cascade and Generative Naming Treatment5. Treatment included self-cueing for naming by engaging residual cognitive processes and further training these strategies in the context of generative naming for semantic categories (e.g., tools, animals. Direct treatment effects and generalization to untrained tasks were documented

    This paper proposes a way of framing the study of ‘noncommunicable diseases’ within the more general area of chronic conditions. Focusing on Africa, it takes as points of departure the situation in Uganda, and the approach to health issues developed by a group of European and African colleagues...... over the years. It suggests a pragmatic analysis that places people's perceptions and practices within a field of possibilities shaped by policy, health care systems, and life conditions. In this field, the dimensions of chronicity and control are the distinctive analytical issues. They lead on to...... consideration of patterns of sociality related to chronic conditions and their treatment....

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

  7. Chronic penile strangulation

    Directory of Open Access Journals (Sweden)

    Lopes Roberto I

    2003-01-01

    Full Text Available Chronic penile strangulation is exceedingly rare with only 5 cases previously reported. We report an additional case of progressive penile lymphedema due to chronic intermittent strangulation caused by a rubber band applied to the penile base for 6 years. A 49-year-old man presented incapacity to exteriorize the glans penis. For erotic purposes, he had been using a rubber-enlarging band placed in the penile base for 6 years. With chronic use, he noticed that his penis swelled. Physical examination revealed lymphedema of the penis, phimosis and a stricture in the penile base. The patient was submitted to circumcision and the lymphedema remained stable 10 months postoperatively. Chronic penile incarceration usually causes penile lymphedema and urinary disturbance. Treatment consists of removal of foreign devices and surgical treatment of lymphedema.

    Directory of Open Access Journals (Sweden)

    Khadilkar Satish

    2011-01-01

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

    Abstract Idiopathic chronic eosinophilic pneumonia (ICEP) is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than ...

The clinical, radiological, and histological appearances of this case will be discussed.

  18. Hypertension in Chronic Glomerulonephritis.

    Science.gov (United States)

    Ihm, Chun-Gyoo

    2015-12-01

    Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the deterioration of renal function. Patients with chronic GN become salt sensitive as renal damage including arteriolosclerosis progresses and the consequent renal ischemia causes the stimulation of the intrarenal renin-angiotensin-aldosterone system(RAAS). Overactivity of the sympathetic nervous system also contributes to hypertension in chronic GN. According to the KDIGO guideline, the available evidence indicates that the target BP should be ≤140mmHg systolic and ≤90mmHg diastolic in chronic kidney disease patients without albuminuria. In most patients with an albumin excretion rate of ≥30mg/24 h (i.e., those with both micro-and macroalbuminuria), a lower target of ≤130mmHg systolic and ≤80mmHg diastolic is suggested. The use of agents that block the RAAS system is recommended or suggested in all patients with an albumin excretion rate of ≥30mg/ 24 h. The combination of a RAAS blockade with a calcium channel blocker and a diuretic may be effective in attaining the target BP, and in reducing the amount of urinary protein excretion in patients with chronic GN.

    2012-01-01

    Full Text Available Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.

  1. Management of chronic paronychia

    Directory of Open Access Journals (Sweden)

    Vineet Relhan

    2014-01-01

    Full Text Available Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management.

  2. Lactoferrin in Chronic Pancreatitis

    Directory of Open Access Journals (Sweden)

    Chun Xiang Jin

    2009-05-01

    Full Text Available The present review is focused on the clinical significance of lactoferrin in pancreatic secretions and stone formation in chronic pancreatitis, and of serum anti-lactoferrin antibody in autoimmune pancreatitis. Lactoferrin secretion is increased in pancreatic secretions in calcified and non-calcified chronic pancreatitis. Lactoferrin, pancreatic stone protein and trypsin are present in pancreatic stones. We cannot conclude which protein is more important for the precipitate and stone formation. The presence of antilactoferrin antibody has been reported in serum in autoimmune diseases, such as autoimmune pancreatitis. The coincidental appearance of autoimmune pancreatitis with extrapancreatic autoimmune diseases strongly suggests a common autoimmune mechanism and lactoferrin is a candidate antigen. Lactoferrin may play an important role as a precipitate protein in pancreatic stone formation in chronic pancreatitis and as an autoantigen in autoimmune pancreatitis. Further studies are required to better understand the role of lactoferin.

  3. Chronic urticaria: recent advances.

    Science.gov (United States)

    Greaves, Malcolm W; Tan, Kian Teo

    2007-10-01

    Chronic urticaria is an umbrella term, which encompasses physical urticarias, chronic "idiopathic" urticaria and urticarial vasculitis. It is important to recognize patients with physical urticarias as the investigation and treatment differs in important ways from patients with idiopathic chronic urticaria or urticarial vasculitis. Although relatively uncommon, urticarial vasculitis is an important diagnosis to make and requires histological confirmation by biopsy. Underlying systemic disease and systemic involvement, especially of the kidneys, should be sought. It is now recognized that chronic "idiopathic" urticaria includes a subset with an autoimmune basis caused by circulating autoantibodies against the high affinity IgE receptor (FceR1) and less commonly against IgE. Although the autologous serum skin test has been proven useful in prompting search for and characterization of circulating wheal-producing factors in chronic urticaria, its specificity as a screening test for presence of functional anti-FceR1 is low, and confirmation by demonstration of histamine-releasing activity in the patient's serum must be the benchmark test in establishing this diagnosis. Improved screening tests are being sought; for example, ability of the chronic urticaria patient's serum to evoke expression of CD 203c on donor human basophils is showing some promise. The strong association between autoimmune thyroid disease and autoimmune urticaria is also an area of ongoing research. Drug treatment continues to be centered on the H1 antihistamines, and the newer second-generation compounds appear to be safe and effective even in off-label dosage. Use of systemic steroids should be confined to special circumstances such as tapering regimens for acute flare-ups. Use of leukotriene antagonists is becoming popular, but the evidence for efficacy is conflicting. Cyclosporin is also effective and can be used in selected cases of autoimmune urticaria, and it is also effective in non

  5. Chronic lead poisoning

    Energy Technology Data Exchange (ETDEWEB)

    1974-02-19

    A detailed description is given of the complex pathological picture observed in the case of a worker with 30 years' occupational exposure to lead in an accumulator factory (evolution of the disease, clinical findings, autopsy). In spite of a typical clinical picture, lead is not held responsible for the terminal encephalopathy, in view of the fact that Alzheimer's syndrome was discovered at autopsy. However, the neurovegetative asthenia and progressive kidney disease without hypertonia, but with uraemia, which preceded the encephalopathy are in all probability due to chronic lead poisoning. The article discusses the diagnosis and symptomatology of chronic lead poisoning, encephalopathy and kidney disease.

    Semantic variant primary progressive aphasia (svPPA) typically presents with left-hemisphere predominant rostral temporal lobe (rTL) atrophy and the most significant complaints within the language domain. Less frequently, patients present with right-hemisphere predominant temporal atrophy coupled with marked impairments in processing of famous faces and emotions. Few studies have objectively compared these patient groups in both domains and therefore it is unclear to what extent the syndromes overlap. Clinically diagnosed svPPA patients were characterized as left- (n = 21) or right-predominant (n = 12) using imaging and compared along with 14 healthy controls. Regarding language, our primary focus was upon two hallmark features of svPPA; confrontation naming and surface dyslexia. Both groups exhibited naming deficits and surface dyslexia although the impairments were more severe in the left-predominant group. Familiarity judgments on famous faces and affect processing were more profoundly impaired in the right-predominant group. Our findings suggest that the two syndromes overlap significantly but that early cases at the tail ends of the continuum constitute a challenge for current clinical criteria. Correlational neuroimaging analyses implicated a mid portion of the left lateral temporal lobe in exception word reading impairments in line with proposals that this region is an interface between phonology and semantic knowledge.

  7. Low chronic radiation doses

    International Nuclear Information System (INIS)

    In the context of the Chernobyl and Fukushima accidents where large territories have been contaminated durably and as consequence where local populations are submitted to chronic low radiation doses, IRSN (French institute for radiation protection and nuclear safety) has led various studies to assess the impact of chronic low doses. Studies about the effects of uranium on marine life show that the impact is strongly dependent on the initial state of the individual (zebra Danio rerio fish). The studies about the impact of chronic low doses due to cesium and strontium contamination show different bio-accumulations: 137Cs is found in the animal's whole body with higher concentrations in muscles and kidneys while 90Sr is found almost exclusively in bones and it accumulates more in female mice than in males. The study dedicated to the sanitary impact of chronic low doses on the workers of the nuclear industry shows a higher risk for developing a leukemia, a pleural cancer or a melanoma but no correlation appears between doses and the appearance of the pleural cancer or the melanoma.

    2013-01-01

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    Full Text Available Sabe-se que o tratamento fonoaudiológico de pacientes com afasia severa é limitado. A ausência de fala articulada, algumas vezes, impede o diagnóstico da afasia. O paciente "grave" pode não falar devido à inabilidade de articulação, como ocorre na disartria e/ou apraxia. Essa ausência de fala não permite afirmar se a linguagem está comprometida. O uso da comunicação suplementar e alternativa tem sido um método eficaz na reabilitação desses pacientes. Esse estudo visou descrever o uso da comunicação suplementar e alternativa associada a outras modalidades de linguagem (escrita, gestos, a partir do relato de dois casos de afasia. A análise dos dados foi composta por dois blocos: a introdução da comunicação suplementar e alternativa no diálogo; e o uso da leitura e escrita associado aos símbolos. A comunicação suplementar e alternativa foi um apoio para a oralidade, leitura e escrita dos pacientes.It is known that the speech-language treatment of patients with severe aphasia is limited. Sometimes the absence of articulated speech is an obstacle to diagnose the aphasia. The patient with severe aphasia might not speak due to articulation inability, as it occurs in dysarthria and/or apraxia, and the absence of speech makes it difficult for speech-language pathologists to determine whether language is also impaired. The use of augmentative and alternative communication techniques has been an effective method for the rehabilitation of these patients. The aim of this study was to describe the use of the augmentative and alternative communication in therapy associated with other modalities of language (written language, gestures, based on the report of two cases of aphasia. Data analysis had two parts: introduction of augmentative and alternative communication in dialogue; and use of reading and writing associated with symbols. The augmentative and alternative communication supported oral language, reading and writing of the

  5. Chronic complicated osteomyelitis

    International Nuclear Information System (INIS)

    Fourteen patients with prior trauma and/or surgery of the lower extremity and suspected active chronic osteomyelitis underwent MR imaging. Eleven patients also underwent In-111 scanning. All patients had surgical confirmation, MR imaging could assess the extent of abnormal marrow and distinguish abnormal marrow due to granulation tissue from active osteomyelitis. The presence and extent of soft-tissue infection could be determined and distinguished from bone involvement in spite of tissue distortion. The course and origin of sinus tracts could be followed. MR imaging was more sensitive to active infection than In-111 scanning. All 11 cases of active osteomyelitis were correctly diagnosed with MR imaging. In-111 scans were positive in only five of the eight cases of active infection in which scans were obtained. MR imaging is useful in chronic complicated osteomyelitis

    On basis of clinical and immunogenetic factors most children with pauciarticular juvenile chronic arthritis can be included in one of the subtypes: type 1 and type 2 pauciarticular JCA. Type 1 occurs in young children, mainly girls, with involvement of knees, ankles or elbows. In the majority of children antinuclear antibodies can be detected. The presence of these autoantibodies is associated with chronic anterior uveitis. Type 2 or the juvenile spondylarthropathies include morbus Bechterew, the reactive arthritides and arthritis associated with psoriasis and inflammatory bowel diseases. Large joints of the lower extremities are involved, back pain is unusual at onset, but enthesitis is frequently present. There is a strong association with HLA-B27. Treatment of both subsets consists of non-steroidal anti-inflammatory drugs, application of intra-articular steroids, physio- and hydrotherapy and splinting. In children with a polyarticular course of type 1, or a prolonged course of type 2 disease modifying drugs are often needed. PMID:1957301

  8. Chronic progressive multiple sclerosis

    International Nuclear Information System (INIS)

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    Persistent cough in children is a symptom, and the cause should be ascertained. Reactive airways disease is the most common reason for chronic cough in children over three to six months of age, especially at night. Under three months, the cause is likely to be more serious. Cough often disturbs parents more than the child, and physicians should consider parents' need for sleep and relief when deciding whether or not to prescribe cough suppressants. Investigations depend on the child's age, th...

    The management of chronic cough, a common complaint in children, is challenging for most health care professionals. Millions of dollars are spent every year on unnecessary testing and treatment. A rational approach based on a detailed interview and a thorough physical examination guides further intervention and management. Inexpensive and simple homemade syrups based on dark honey have proved to be an effective measure when dealing with cough in children. PMID:23905830

    It has been recognized that during chronic inflammatory systemic diseases (CIDs) maladaptations of the immune, nervous, endocrine and reproductive system occur. Maladaptation leads to disease sequelae in CIDs. The ultimate reason of disease sequelae in CIDs remained unclear because clinicians do not consider bodily energy trade-offs and evolutionary medicine. We review the evolution of physiological supersystems, fitness consequences of genes involved in CIDs during different life-history sta...

    Chronic pneumonitis of infancy (CPI) is a very rare lung disease in infants and young children. We report a 33-day-old infant with CPI, focusing on the radiologic aspects of the disease. Chest radiographs showed variable and non-specific appearances including ground-glass shadowing, consolidation, volume loss, and hyperinflation. Dense alveolar opacities progressed as CPI advanced. The radiologic features of our case reflected pathologic changes. (orig.)

    Chronic renal failure is characterised by a gradual and sustained decline in renal clearance or glomerular filtration rate (GFR). Continued progression of renal failure will lead to renal function too low to sustain healthy life. In developed countries, such people will be offered renal replacement therapy in the form of dialysis or renal transplantation. Requirement for dialysis or transplantation is termed end-stage renal disease (ESRD).Diabetes, glomerulonephritis, hypertension, pyelone...

    Chronic cough has been suggested to be due to three conditions, asthma, post nasal drip, and reflux disease. A different paradigm has evolved in which cough is viewed as the primary condition characterised by afferent neuronal hypersensitivity and different aspects of this syndrome are manifest in the different phenotypes of cough. There are several advantages to viewing cough hypersensitivity as the unifying diagnosis; Communication with patients is aided, aetiology is not restricted and the...

    The infection from Epstein-Barr virus (EBV or virus of infectious mononucleosis, together with other herpesviruses’ infections, represents a prototype of persistent viral infections characterized by the property of the latency. Although the reactivations of the latent infection are associated with the resumption of the viral replication and eventually with the “shedding”, it is still not clear if this virus can determine chronic infectious diseases, more or less evolutive. These diseases could include some pathological conditions actually defined as “idiopathic”and characterized by the “viral persistence” as the more credible pathogenetic factor. Among the so-called idiopathic syndromes, the “chronic fatigue syndrome” (CFS aroused a great interest around the eighties of the last century when, just for its relationship with EBV, it was called “chronic mononucleosis” or “chronic EBV infection”.

    Today CFS, as defined in 1994 by the CDC of Atlanta (USA, really represents a multifactorial syndrome characterized by a chronic course, where reactivation and remission phases alternate, and by a good prognosis

    Alloantibodies clearly cause acute antibody mediated rejection, and all available evidence supports their pathogenic etiology in the development of chronic alloantibody mediated rejection (CAMR). But the slow evolution of this disease, the on-going immunosuppression, the variations in titer of alloantibodies, and variation in antigenic targets all complicate identifying which dynamic factors are most important clinically and pathologically. This review highlights the pathological factors rela...

  17. Clinicoroentgenological control in chronic pneumonia

    International Nuclear Information System (INIS)

    A comprehensive clinicoroentgenological study was used to examine 494 patients with chronic pneumonia. Morphological and functional changes observed in the pulmonary pare and functional changes observed in the pulmonary parenchyma and bronchial tree were studied. Types of pneumosclerosis, tigns of exacerbation of chronic pneumonia and abscess formation, morphological and functional disorders of bronchial penetrability in the pneumonic zone were described. Three forms of chronic pneumonia: bronchial, bronchiectatic and abscessing are signled out. The bronchial form is subdivided into chronic pneumonia with chronic bronchitis without deformity and wi.th deforming chronic bronchitis. In the bronchiectatic form pneumonia can be with cylindrical, saccular and cyst-like bronchiectasia. The general diagnosis of chronic pneumonia is established clinically depending on type and variants in 89-94% of cases, by X-ray and sonographic findings in all patients; types and variants of disease are most frequently defined after bronchography

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

  19. Imaging of chronic osteomyelitis

    International Nuclear Information System (INIS)

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI.
