We evaluated learning and memory in 50 depressed patients prior to and following 4 week treatment with imipramine compared to 21 normal controls tested at corresponding times. At baseline, the depressives did worse than normals on most memory tasks with the difficult memory tasks, regardless of store, modality or type of task best distinguishing between(More)
Flat affect is a major component of schizophrenia and is often also seen in neurological disorders. A preliminary set of comparisons were conducted to delineate neuropsychological mechanisms underlying flat affect in schizophrenia, and new measures are described for the assessment of affective deficits in clinical populations. Subjects were schizophrenic(More)
The utility of the benzamides in clinical psychiatry requires further evaluation. Of the four compounds mentioned in this chapter, it seems clear that sulpiride is an effective antipsychotic agent as shown by double-blind trials comparing it with placebo and reference antipsychotics (see Table I). Claimed efficacy for this agent in depression, anxiety, and(More)
INTRODUCTION The negative and cognitive symptoms of schizophrenia are poorly responsive to neuroleptic treatment. Glutamatergic dysfunction may mediate some of these symptoms. Low dose D-cycloserine (DCS) is a partial agonist at the glycine site of the NMDA-associated receptor complex, noncompetitively enhancing NMDA neurotransmission. Prior studies suggest(More)
BACKGROUND Several studies have found that alpha-tocopherol (vitamin E) can effectively treat tardive dyskinesia (TD). A limitation of these trials is their short treatment durations (maximum of 12 weeks), which do not allow us to address the effects of long-term treatment. METHODS To participate, patients had to have TD and be on stable oral medications.(More)
Components of emotional processing were examined in psychiatric and neurological populations: communication channel (face/voice), processing mode (expression/perception), and emotional valence (positive/negative). These were assessed with an experimental affect battery which was administered to schizophrenic, unipolar depressive, right-brain-damaged,(More)
A theoretical argument proposes that thresholds for visual perception of movement should be abnormally high in schizophrenia. This may reflect a central vestibular dysfunction, consisting of abnormally high levels of extraneous noise within the neural activity of the central vestibulo-cerebellar complex. Two experiments are reported with results that(More)
To evaluate the role of maladaptive thinking patterns in depression, the authors administered the Dysfunctional Attitude Scale to 112 depressed patients before and after 3-6 weeks of treatment with antidepressants or placebo. Twenty-two normal subjects were also assessed twice. Depressed patients had a significantly higher initial mean score than control(More)
Using a longitudinal life-table analysis, we assessed the efficacy of lithium alone, administered within the context of a naturalistic clinical setting, by calculating the probability of patients remaining free of an affective episode (manic or depressive) over a five-year course. In addition, for those who suffered a manic or depressive relapse, we(More)
