To test the effect of selegiline, a specific monoamine oxidase-B (MAO-B) inhibitor, on the cerebral metabolic and euphorigenic effects of cocaine in experienced users, eight cocaine-dependent (CD) subjects were evaluated using a within-subjects design. Each subject participated in two pairs of [F-18]-fluorodeoxyglucose (FDG)-positron emission tomography(More)
BACKGROUND Office-based treatment of opiate addiction with a sublingual-tablet formulation of buprenorphine and naloxone has been proposed, but its efficacy and safety have not been well studied. METHODS We conducted a multicenter, randomized, placebo-controlled trial involving 326 opiate-addicted persons who were assigned to office-based treatment with(More)
Platelet monoamine oxidase activity (MAO) was studied serially over time in 16 chronic schizophrenic patients when medication free and then when medicated. Thirteen of the 16 patients had significant decreases in platelet MAO activity following neuroleptic drug treatment. The change in MAO activity was found to be correlated with response to treatment and(More)
Central catecholamine concentrations were determined in autopsy brain samples from 19 elderly schizophrenic patients and controls. Data from the hypothalamus and nucleus accumbens demonstrate altered catecholamine metabolism associated with cognitive impairment in these subjects. Both loci show decrements of norepinephrine concentrations, while the nucleus(More)
The University of Southern California Repeatable Episodic Memory Test (USC-REMT) was developed to provide a brief assay of memory in clinical drug trials where the same subject is tested multiple times over days or weeks. Therefore, it had to be minimally affected by repeated testing. The test also provides a measure of subjective organization, a cognitive(More)
A multi-site, open-label study of methylphenidate for treating patients with comorbid diagnoses of attention deficit/hyperactivity disorder and cocaine dependence was performed. Forty-one participants, who met DSM-IV criteria for adult attention deficit/hyperactivity disorder and cocaine dependence, were enrolled into this ten week outpatient study. The(More)
Central catecholamine concentrations were determined in autopsy samples from older schizophrenic and control subjects for both the hypothalamus and the nucleus accumbens. The results of these analyses and demographic variables were regressed on antemortem measures of cognitive function and mood state. In the hypothalamus, there are significant direct(More)
