Brief Summary

The purpose of this study is to evaluate the safety and efficacy of citalopram for agitation in Alzheimer's dementia.

Detailed Description

This study is designed to examine the efficacy and safety of citalopram as treatment for clinically significant agitation in Alzheimer's dementia (AD) patients. It will also investigate pharmacogenomic, genetic, and clinical predictors of response to citalopram therapy. The management of agitation is a major priority in treating patients with AD. Non-pharmacologic options have limited effectiveness. Several pharmacologic options have been explored, but findings for anticonvulsants, antipsychotics, and cholinesterase inhibitors are disappointing or associated with questionable risk-benefit ratio. Better pharmacologic options are needed. Selective serotonin reuptake inhibitors (SSRIs) show promise as a treatment for agitation in AD, based on evidence of a link between agitation and brain serotonin system abnormalities in AD patients, and on preliminary clinical data from a single-site, randomized controlled trial (RCT) in which citalopram was superior to perphenazine and placebo.

Primary Outcome Measures
NameTimeMethod
Modified Alzheimer's Disease Cooperative Study- Clinical Global Impression of Change in Agitation(CGIC)Baseline to 9 weeks

Modified Alzheimer's Disease Cooperative Study- Clinical Global Impression of Change in agitation(CGIC) accesses clinically significant change in agitation. A trained clinician, blind to treatment assignment, uses a 7-point Likert scale to rate change of each patient along a continuum from "marked improvement"(1), "no change"(4), and "marked worsening"(7). A number of aspects of the agitation is considered such as emotional agitation, mood liability/distress, psychomotor agitation, verbal aggression, and physical aggression. Range is 1-7.

NeuroBehavior Rating Scale-- Agitation9 weeks

NeuroBehavioral Rating Scale- Agitation(NBRS-A) assesses multiple types of psychopathology common in dementia and is based on a seven point Likert scale of increasing severity for each item(i.e., 0=not present, 1=very mild, 2-mild, 3=moderate, 4=moderately severe, 5=severe, 6=extremely severe). The NBRS agitation subscore includes NBRS 'inhibition', 'agitation', and 'hostility'. The range is 0 to 18 points. Higher scores indicate more symptoms.

Secondary Outcome Measures
NameTimeMethod
Neuropsychiatric Inventory (NPI)-- Agitation Subscore9 weeks

NPI agitation score is based on responses from an informed caregiver involved in the patient's life. Symptom severity (1=mild, 2=moderate, 3=severe) is multiplied by frequency (1=occasionally, less than once/week; 4 = very frequently, once or more/day or continuously) to obtain the NPI agitation score.Range is 0-12. Higher scores indicate more severe symptoms.

Cohen-Mansfield Agitation Inventory (CMAI)9 weeks

CMAI examines several agitated behaviors including verbal, physical agitation, and other behaviors. Sub-items are summed. Range is 14-70. Higher scores indicate more severe symptoms.
