Particularly significant findings were observed when data from the unipolar subgroup (n = 22) were analyzed separately. Unipolar psychotic… (More)
Cocaine abuse is widespread and has been associated with serious neurovascular complications. We studied a group of cocaine-dependent polydrug users with 99mTc-HMPAO and high-resolution SPECT and compared their perfusion pattern to cerebral perfusion in a group of older control subjects. Sixteen of 18 cocaine-dependent polydrug users had abnormal perfusion… (More)
In 16 inpatients with acute mania, neuropsychological evaluation revealed a trend toward correlation between less insight (lower scores on the Insight and Treatment Attitudes Questionnaire, ITAQ) and improved delayed visual recall. This result may either reflect the absence of a relationship between neuropsychological abnormalities and lack of insight in… (More)
