Effects of Eszopiclone on Sleep and Memory in Schizophrenia
Completed · Not applicable · Has a placebo group
Conditions studied: Schizophrenia
In brief
The investigators will test the hypothesis that the sleep medication, eszopiclone, can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance on two conditions separated by one week: taking 3 mg of eszopiclone and taking placebo. The investigators will study healthy subjects and chronic, medicated outpatients with schizophrenia.
