Characteristics of auditory agnosia in a child with severe traumatic brain injury: a case report.

We present a case that is unusual in many respects from other documented incidences of auditory agnosia, including the mechanism of injury, age of the individual, and location of neurological insult. The clinical presentation is one of disturbance in the perception of spoken language, music, pitch, emotional prosody, and temporal auditory processing in the absence of significant deficits in the comprehension of written language, expressive language production, or peripheral auditory function. Furthermore, the patient demonstrates relatively preserved function in other aspects of audition such as sound localization, voice recognition, and perception of animal noises and environmental sounds.

Neuropsychological functioning in major depression and responsiveness to selective serotonin reuptake inhibitors antidepressants.

Background: Only two thirds of patients with major depression (MD) respond to antidepressants. Thus, far applicable predictors of responsiveness to selective serotonergic reuptake inhibitors (SSRIs) have not been found. Cumulative evidence linking serotonergic depletion and cognition led us to hypothesize that the neuropsychological functioning of major depression patients may predict their responsiveness to SSRI antidepressants.

Reading direction and spatial neglect.

Many American and European investigators have reported that hemispatial neglect is more frequent and more severe after right than left hemisphere lesions. This hemispheric asymmetry may be due to biological asymmetries, learned behavior, or both. Readers of European languages, unlike readers of Semitic languages, scan from left to right.
