Neuropsychological performance, mood, and complaints of cognitive and motor difficulties in individuals infected with the human immunodeficiency virus.

Seventy-nine military medical beneficiaries infected with human immunodeficiency virus (HIV+) and 27 HIV-seronegative control subjects (HIV-) completed a neuropsychological evaluation and a semistructured interview inquiring about difficulties in function. More HIV+ than HIV- subjects reported difficulties. HIV+ subjects reporting difficulties were significantly more likely to be deficient on attention, response speed, motor function, and memory than those not reporting difficulties. Findings for early-stage HIV+ subjects were similar. HIV+ individuals who complained of difficulties reported depression and anxiety symptoms significantly more frequently than those who did not complain, but these symptoms were not related to neuropsychological performance. Complaints of difficulties by HIV+ individuals may reflect either actual neuropsychological deficiency or mood disturbance, but the effects of each appear to be independent.

The progressive breakdown of number processing and calculation ability: a case study.

We examined a retired Army General with Progressive Dementia whose initial major presenting complaint was dyscalculia. Our examinations revealed an orderly dissolution of calculation ability with differing dissociations in calculation ability apparent at progressive stages of cognitive decline. For example, we found that number reading and writing errors were qualitatively different from calculation errors. Numerosity knowledge and magnitude comparisons can remain intact even when other arithmetic knowledge and calculation abilities were grossly impaired. His decline in calculation abilities was first demonstrated on more complex problems (e.g., multiplication) and only in later stages on simpler (e.g., addition) problems. The patient was aware that aspects of his performance were impaired, but he was unable to state why--a dissociation between declarative and procedural knowledge.

Utilization of nurse clinicians and physician assistants by Active members and Fellows of the American Academy of Neurology.

A study of 343 Active members and Fellows of the American Academy of Neurology revealed that among 285 responders who spent over 10 hours per week in direct patient care, 198 were in private practice, 69 worked exclusively for institutions, and 18 worked part time in each setting. Eighty-three (29%) used extenders in their practice. Institutionally based neurologists were significantly more likely to use extenders than those in private practice.
