Damage to the dominant arcuate fasciculus degrades auditory comprehension in non-fluent aphasia / 中华物理医学与康复杂志

Objective@#To investigate the correlation between damage to the dominant arcuate fasciculus (AF) and the occurrence of auditory comprehension dysfunction in post-stroke aphasia.@*Methods@#Eighteen stroke survivors with non-fluent aphasia were recruited into the observation group, and nine healthy counterparts were chosen for the control group. All received diffusion tensor imaging (DTI) scans and fractional anisotropy (FA) values were measured. A Chinese aphasia battery was used to evaluate the aphasics′ language functioning, with the listening true or false, listening recognition and oral instruction auditory comprehension sub-scales used as the observation indices.@*Results@#There were significant differences between the two groups in the FA value of the dominant AF. Spearman correlation showed that the FA value of the dominant AF was positively related to the listening recognition results.@*Conclusions@#Damage to the dominant AF may be one of the reasons for auditory comprehension dysfunction in post-stroke aphasia.

Damage Level and Mechanism of Language Processing in An Auditory Agnosia Patient Using Psycholinguistic Assessment / 中国康复理论与实践

@#Objective To evaluate the damaged level of auditory processing and diagnose the type of language impairment in an auditory agnosia patient using Psycholinguistic Assessment in Chinese Aphasia (PACA), and predict the outcome of the language function. Methods A patient with a bilateral damage involving the temporal lobe could physically hear the sounds, but was unable to recognize or differentiate between the sounds. Speech and language evaluations were taken with PACA 4 weeks, 8 weeks and 3 months after the onset of disease. Results At 4 weeks, the correct rates were 2.5% and 95.0% in spoken word-picture matching and written word-picture matching (P<0.001), and were 5.6% and 80.6% in spoken semantic knowledge and written semantic knowledge (P<0.001). The scores of auditory input processing function score were low, including phoneme discrimination, spoken word matching with minimal differences, environmental sounds identification. The correct rates were 67.5% in oral picture naming, 0 in word repetition, 70.0% in word reading, 0 in dictation, 100.0% in directly copy writing. At 8 weeks and 3 months, there was complete recovery in written word- picture matching (both 100%) and written semantic knowledge (97.2%, 100%), and improvement in oral picture naming (87.5%, 90%), word repetition (87.5%, 97.5%), picture name writing (77.5%, 87.5%) and copy writing (both 100%) (P<0.05). But no change was found in auditory input processing function examinations, spoken word-picture matching (5.0%, 7.5%), spoken semantic knowledge (2.8%, 5.6%), word repetition (0, 3.3%) and dictation (both 0). Conclusion The patient was diagnosed as auditory agnosia with the inability to distinguish sounds. PACA can well identify the impaired level of auditory comprehension disorder and the outcome of language function recovery for aphasics.

PACA can well identify the impaired level of auditory comprehension disorder and the outcome of language function recovery for aphasics.

A possible correlation between vestibular stimulation and auditory comprehension in children with attention-deficit/hyperactivity disorder

Twenty children, aged 10 to 12 years with attention-deficit/hyperactivity disorder (ADHD), were selected to study the effect of vestibular stimulation on auditory perception and sensitivity using the Integrated Visual and Auditory Continuous Performance Test (IVA CPT; a neuropsychological test that is applied in occupational therapy clinics). The present study examined children based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision. After obtaining guardian and parental consent, the children were enrolled in the study and randomly matched according to age across intervention and control groups. The IVA CPT was applied as a pre-test. The children in the intervention group then received vestibular stimulation during therapy sessions twice per week for 10 weeks. The IVA CPT assessment (post-test) was then applied in both groups. The mean pre- and post-test scores were compared across groups. The statistical analyses revealed a significant difference in improvement in auditory comprehension. In conclusion, the present findings suggest that vestibular training is a reliable and powerful treatment option for ADHD, especially when combined with other training. Stimulating the sense of balance highlights the important interaction between inhibition and cognition...

Study on the auditory comprehension impairments of Chinese aphasics in cerebrovascular diseases / 中国康复理论与实践

@#ObjectiveImpairment in auditory comprehension is one of the most common clinical symptoms of aphasia. Analysing the features of Chinese aphasics in auditory comprehension might be valueable to classify the types of aphasia, distinguish the difference between the Western aphasics and Chinese aphasics, and find out the neural mechanisms in the language processes in the brain. MethodsThe Standardized Aphasia Battery in Chinese and Additional Test of Auditory Comprehension were utilized, and the cerebral lesion of each case was demonstrated by CT scan or MRI. Results and Conclusions 1.Different types of aphasia indicate different damage grades in auditory comprehension impairment at each stage. 2. Posterior apasia and mixed aphasia indicate damages in the phonemic discrimination abilities. There are phonemic discrimination abilities preserved in Anterior aphasia and subcortical aphasia. 3. Anterior aphasia, posterior aphasia and mixed aphasia are at a different difficulty grades for lexical comprehension, especially for the discrimination to body parts. Subcortical aphasia doesn\'t demonstrate this feature that might be the characteristic in Chinese aphasics different from English aphasics. 4. The comprehension of the passive sentences is more difficult than that of the active sentences for all types of aphasics . 5. The damages are all severe in the story comprehension for all types of aphasics.

The Differential Diagnosis Flow Diagram of Aphasia Types in Chinese Aphasia / 中国康复理论与实践

@# It was introduced that the Aphasia Battery of Chinese (ABC), proposed by neurology department of Beijing Medical University. According to the experience of aphasia research for 1O years, we summarized the main types of Chinese aphasia and the differential diagnostic principles for them,and the differential diagnosis flow diagram of all major Chinese aphasia types was advanced according to the four principles-Ai repetition, fluency, auditory comprehension and oral or written language disorders. It was pointed out the classification of aphasia will provide the reliable basis for language rehabilitation and the four principles offer the information for localized lesions of brain.
