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)
Brain perfusion is abnormal in chronic cocaine users. To determine whether these perfusion abnormalities are reversible following treatment, we studied 10 cocaine-dependent polydrug users with 99mTc-HMPAO SPECT 2 to 3 days after admission to an inpatient treatment facility and at 7 to 8 days and 17 to 29 days after abstinence from drugs. The patients also(More)
Intravenous drug use is a major risk factor for HIV-1 infection. Since both AIDS dementia complex (ADC) and cocaine have been associated with abnormal brain perfusion imaging, we compared the scintigraphic patterns of ADC patients and cocaine polydrug users with normal control subjects using 99mTc-HMPAO SPECT. We found a high incidence of cortical defects(More)
Pituitary gland volume was measured in 16 men between the ages of 26-33 with magnetic resonance imaging. Eight male patients had a Diagnostic and Statistical Manual III-Revised, American Psychiatric Association Axis I diagnosis of concurrent opioid and cocaine dependence. The average duration of opioid and cocaine abuse was 7.8 +/- 2.0 and 6.9 +/- 1.4 yr,(More)
