Delaying Alzheimer Disease Symptoms With Anti-Inflammatory Drugs

• Status: Completed
• Trial end date: 2005-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine whether the anti-inflammatory drug celecoxib can delay the onset of Alzheimer Disease (AD) in people with Age Associated Memory Impairment (AAMI). This study will also evaluate genetic risk and brain structure as potential predictors of mental decline.

• Phase: N/A
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

• Lead Sponsor: University of California, Los Angeles

• Normal screening laboratory tests and electrocardiogram (ECG)

Exclusion Criteria:

• Possible or probable Alzheimer Disease (AD) or other dementia

Occasional chloral hydrate use will be allowed, but discouraged, for insomnia.

• Investigational drugs within the previous month or longer, depending on drug half-life

• Contraindication for MRI scan (e.g., metal in body, claustrophobia)
