Cognitive impairment screening in second offense DUI programs.

Patients enrolled in alcohol treatment programs for driving under the influence (DUI) offenders are at elevated risk of cognitive impairment, but are not systematically screened. We developed a 30-min screening battery that can be administered in a group setting to test patients' ability to handle the cognitive demands of psychoeducational treatment. Testing of 134 volunteers identified 73% as having one or more clinically significant cognitive deficits. A majority of subjects scored below the 50th percentile on tests of word fluency, vocabulary, sustained attention, memory, executive functioning, and impulse control. The prevalence of cognitive impairment in the repeat DUI offender population is extremely high, making DUI treatment programs an ideal venue for screening and referral. Treatment programs should be responsive to the special needs of this population, incorporating teaching techniques that address short attention span, poor memory, lack of verbal fluency, and lack of impulse control.

A potential noninvasive neurobiological test for Alzheimer's disease.

Currently Alzheimer's disease, which affects more than 20 million people worldwide, can only be definitely diagnosed by histological examination of brain tissue obtained at autopsy or biopsy. There is a great need for an early, noninvasive, sensitive, and easily administered diagnostic test of Alzheimer's disease. Here it is reported that patients diagnosed with probable Alzheimer's disease by standard clinical criteria exhibited a marked hypersensitivity in their pupil dilation response to a cholinergic antagonist, tropicamide, placed in their eyes. It was possible to distinguish 18 of 19 individuals (95%) either clinically diagnosed with Alzheimer's disease or classified as suspect Alzheimer's individuals by neuropsychological screening from 30 of 32 normal elderly controls (94%).

Right hemisphere learning disability associated with left hemisphere dysfunction: anomalous dominance and development.

Two patients are described with the social emotional processing disorder, a developmental syndrome usually ascribed to right hemisphere dysfunction. In these two patients however, neurological examinations, EEG, and neuroimaging studies were all consistent with left hemisphere dysfunction. Both patients were left handed and had findings suggestive of anomalous dominance for language. It is proposed that early left hemisphere injury may have resulted in functional reorganisation that allowed sparing of language and motor skills but interfered with the development of functions that the right hemisphere normally subserves.
