The performance of children with auditory perceptual disorders on a time-compressed speech discrimination measure.

A time-compressed version of the PB-K 50 speech discrimination measure was administered to 20 children diagnosed as displaying auditory perceptual disorders. Results indicated that these children performed equally well at both 0 and 30% time compression. Performance decreased significantly at 60% time compression. Comparison of the results with normative data indicated that performance of the two groups of children was similar at the 30% time compression condition but that children with auditory perceptual disorders performed poorer at both 0 and 60% time compression. The results were discussed relative to short-term memory abilities.

The predictive validity and accuracy of a screening test for language delay and auditory perceptual disorder.

Infants (321) who had been screened for language delay and auditory perceptual problems at 9 months of age were evaluated 1 year later. Of these infants 88.6% were correctly classified as at-risk or not-at-risk of delayed linguistic development. The correlation between performance on the screen and on a language scale was 0.49. The great majority of those with receptive and expressive delay continued to show problems at 2 years of age, whereas half of those with expressive delay alone were within normal limits. No evidence was found that a history of fluctuating hearing loss contributed to the development of either language delay or auditory perceptual problems.

Effects of stimulus-onset asynchrony on the dichotic performance of children with auditory-processing disorders.

Dichotic stop-consonant-vowel identification was investigated in two experiments using two groups of learning-disabled children demonstrating clinical manifestations of auditory-processing disorders, and two groups of matched, control subjects. Two-item, forced-choice paradigms were used in both experiments. Overall (total) dichotic performance for the two learning-disabled groups was significantly lower than that of the control subjects in all dichotic conditions. This lower performance was attributable to the number of trials in which both stimulus items were correctly identified. Analysis of trials in which only one response was correct showed no differences between the groups in terms of magnitude or direction of ear-advantage (right). In conditions where stimulus onsets were separated by 30, 90, and 150 msec, analysis of one-correct trials demonstrated more accurate identification of the temporally lagging stimulus for all subjects. However, as the onset-time separation increased, the control group's identification of leading and lagging items approached equality. The learning-disabled group, on the other hand, showed little increase in identification of temporally leading items even when stimuli were separated by 150 msec. These data suggest learning-disabled children with auditory-processing disorders may have a reduced temporal efficiency in processing rapidly varying acoustic patterns associated with stop-consonants that is observable when speech perceptual mechanisms are stressed through dichotic competition.

The use of electroconvulsive therapy in patients with dissociative disorders.

The psychiatric literature generally discourages the use of electroconvulsive therapy (ECT) to treat depression in dissociative disorder patients, but contains little data on outcome. This prospective study of ECT in three dissociative disorder patients demonstrates that ECT is indicated for severe treatment-resistant depression in such patients. Their Hamilton Depression Scale scores fell by 50%, they were remarkably clinically improved, and they maintained their gains for at least 4 months. The ECT proved helpful when depression was felt by most of the active alters rather than just by one depressed personality. Mini-Mental State Examination scores and clinical observation revealed no unusual confusion or side effects from ECT. These patients' dissociated condition was not altered by ECT, which indicates that ECT neither treats nor impairs treatment of dissociation. Electroconvulsive therapy can be helpful in the overall treatment of dissociative disorders by alleviating severe depressions which block utilization of psychotherapy.

Response patterns to central auditory tests and the clinical evaluation of Language Fundamentals--Revised: a pilot study.

Tests of central auditory function and measures of receptive and expressive language abilities were administered to 10 children suspected of having central auditory processing disorders. Eight of the 10 subjects displayed expressive language difficulties, suggesting a need to examine more closely the relationship between expressive language and central auditory processing.

Organic mental disorders associated with bupropion in three patients.

Bupropion hydrochloride is a phenylaminoketone antidepressant whose clinical pharmacology is poorly understood. Part of bupropion's action may be attributed to inhibition of dopamine reuptake that may induce organic mental disorders in certain susceptible patients. We report three cases of organic mental disorders in patients receiving bupropion hydrochloride for treatment of the depressed phase of their bipolar-type mood instability. The organic mental disorders that occurred in these patients were characterized largely by visual disturbances--visual hallucinations and visual illusions--although one patient also experienced auditory hallucinations. The patients' use of concomitant medications and potential drug interactions are carefully evaluated and the literature on bupropion's ability to induce organic mental disorders is reviewed. We suggest a number of possible mediating mechanisms for these syndromes including dose-related dopaminergic augmentation, accumulation of toxic metabolites, predisposition to psychosis, and drug interactions.

Lead exposure and the central auditory processing abilities and cognitive development of urban children: the Cincinnati Lead Study cohort at age 5 years.

This analysis examined the relationship between lead exposure as registered in whole blood (PbB) and the central auditory processing abilities and cognitive developmental status of the Cincinnati cohort (N = 259) at age 5 years. Although the effects were small, higher prenatal, neonatal, and postnatal PbB levels were associated with poorer central auditory processing abilities on the Filtered Word Subtest of the SCAN (a screening test for auditory processing disorders). Higher postnatal PbB levels were associated with poorer performance on all cognitive developmental subscales of the Kaufman Assessment Battery for Children (K-ABC). However, following adjustment for measures of the home environment and maternal intelligence, few statistically or near statistically significant associations remained. Our findings are discussed in the context of the related issues of confounding and the detection of weak associations in high risk populations.

Psychotic symptoms and suicidal behavior in hospitalized children.

Association of psychotic symptoms with suicidal behavior was studied in 90 hospitalized prepubertal children. Children with psychotic symptoms were more likely to have threatened or attempted suicide. The association of visual hallucinations with suicidal behavior was stronger than that of auditory hallucinations or psychotic ideation. The authors speculate that psychosis in general and visual hallucinations especially may be indicators of suicide risk among children.

Toward a brain map of auditory hallucinations.

OBJECTIVE: This study asks whether auditory hallucinations are reflected in a distinctive metabolic map of the brain. METHOD: Regional brain metabolism was measured by positron emission tomography with [18F]-fluorodeoxyglucose in 12 DSM-III schizophrenic patients who experienced auditory hallucinations during glucose uptake and 10 who did not. All patients were free of neuroleptics and 19 had never been treated with neuroleptics. Nine patients were reexamined after 1 year to assess effects of neuroleptic treatment. RESULTS: Compared with the patients who did not experience hallucinations, the patients who did experience hallucinations had significantly lower relative metabolism in auditory and Wernicke's regions and a trend toward higher metabolism in the right hemisphere homologue of Broca's region. Hallucination scores correlated positively and significantly with relative metabolism in the striatum and anterior cingulate regions. Neuroleptic treatment resulted in a significant increase in striatal metabolism and a reduced frontal-parietal ratio, which was significantly correlated with a decrease in hallucination scores. CONCLUSIONS: Auditory hallucinations involve language regions of the cortex in a pattern similar to that seen in normal subjects listening to their own voices but different in that left prefrontal regions are not activated. The striatum plays a critical role in auditory hallucinations.

Chronic middle ear disease and auditory perceptual deficits: is there a link?

Data are presented indicating a correlation between chronic recurrent otitis media of early childhood and in increased likelihood of subsequent auditory processing deficits in a group of children referred for evaluation of impaired learning. Helpful appendices are added for a better understanding a central auditory processing skills.

Failure of a binaural comprehension deficit to select responders to earplug use in schizophrenia.

Previous studies have suggested that on the Auditory Comprehension Test, a significant proportion of schizophrenics demonstrate a binaural comprehension deficit. To test whether wearing an earplug in their more poorly performing ear would be beneficial, we studied 34 in-patient schizophrenics and noted a binaural deficit in 12 (35%). Of these, eight patients subsequently wore an earplug in each ear for at least one week. We found no effect of the earplug on psychopathology.

Screening for perceptual skills dysfunction: an up-date.

The paper argues that the primary-care practitioner has an obligation to screen the visual and auditory perceptual skills of all his/her elementary school-aged patients. Two easy-to-administer tests are described, along with guidelines for interpreting and making decisions on the basis of test outcomes.

[Recognition of onomatopoeias and animal cries during focalized lesions of the cerebral cortex (author's transl)].

The recognition of animal cries and their onomatopoeias was compared during the course of right or left unilateral cortical lesions. A double dissociation is noted; in left-sided affections there is a more severe deficiency to onomatopoeia than to cries, whereas in right-sided lesions the quality of the performances is reversed. These results suggest that the right hemisphere is dominant in the auditive recognition of familiar sounds, and supply information as to the linguistic value of onomatopoeias.
