Brief Summary
-----------------
Purpose : to Evaluation of the Efficacy of Escitalopram for the Treatment of Depression in Alzheimer's Disease Trial Design : A 12-week, randomized, double-blind, parallel-group, placebo-controlled trial with an open-label, 12-week extension

Detailed Description
-----------------
Clinical trial agreement signed by the parties to the subjects through a process of screening. if it is consider suitable for evaluating through the selection / exclusion criteria, they will be randomly assigned to the test group or control group (placebo). Assigned to the test group or control subjects, they will be prescribe the 5mg Escitalopram or Placebo. without regard to meals, it will be taking once a day. and than It should be increased the capacity every two weeks by 5mg/day up to a maximum 15mg/day. and than, on the treatment for a 8 weeks, If you don't find the side effect, Maintaining the same capacity.
