Primary outcomePrimary: Apathy Evaluation Scale Score at 12 Weeks — 38.2; 43.6 units on a scale — p=<0.05

Summary

The purpose of the study is to determine the efficacy of methylphenidate over placebo in treating apathy in patients with Alzheimer's dementia. Apathy is one of the earliest and most profound disturbances that occur in Alzheimer's dementia (AD). Hypotheses: 1. Methylphenidate (MPH) will improve apathy significantly more than placebo in AD. 2. Successful treatment of apathy will improve Instrumental Activities of Daily Living (IADLs), and caregiver burden.
