Abstract:
:We compared the EEG-monitored sleep of 8 women with anorexia nervosa and 16 normal weight women with bulimia to that of 14 normal women. The patients with anorexia nervosa spent less time asleep and spent less of their sleep time in Stage 1. The sleep of the normal weight patients with bulimia was remarkably similar to that of the controls. These data suggest that most patients with anorexia nervosa and bulimia do not exhibit the type of sleep disturbances characteristic of patients with major depressive illness.

杂志文章abstract:BACKGROUND:How clozapine exerts superior antipsychotic efficacy in treatment-resistant schizophrenia is not known. Moderate (rather than "full") occupancy of D2 postsynaptic receptors may be crucial, perhaps by achieving a more effective D1/D2 or serotonin-2a/D2 ratio. The objective of this study was to test the modera...
