Summary

The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of placebo in improving sleep efficiency in people with dementia admitted to the hospital because of their symptoms. You can participate in this study if you have dementia of the Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We will use placebos to see if the study results are due to the study drug or due to other reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription. Zolpidem CR is approved by the U. S. Food and Drug Administration (FDA) for the short-term treatment of insomnia (trouble falling or staying asleep).

Clinical Details

Official title: Does Zolpidem CR Treatment Change Clinical Outcomes in Elderly Hospitalized Patients With Dementia- A Pilot Study

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Sleep efficiency and other actigraphy derived sleep parameters

Secondary outcome: Measures of aggression, psychosis, general clinical status, cognitive measures, mood symptoms, length of hospital stay, and percentage of patients who remain on Zolpidem CR at the end of the study.

Detailed description: Sleep patterns normally change with age. Sleep/wake cycles appear to be compromised in people suffering from dementia. Most research involving sleep in dementia has involved community dwelling or nursing home residents. Relatively little is known about the sleep patterns of patients with dementia who develop acute behavioral and psychiatric symptoms and necessitate hospitalization. The relationship between sleep disturbances in these patients and behavioral/psychiatric symptoms is also insufficiently studied. The current study will examine these two sets of data (sleep/wake cycles and clinical symptoms) in a population of elderly subjects with Dementia of the Alzheimer's type (DAT) or vascular dementia (VD) during their hospitalization period. We will compare the sleep outcome measures (primarily sleep efficiency) and clinical outcome measures in subjects treated with Zolpidem CR or Placebo. We will utilize a double-blind, randomized, placebo-controlled design to test our hypothesis that targeting sleep disturbances in hospitalized elderly subjects with DAT or VD leads to improvement in sleep and clinical outcomes.
