Escitalopram 20mg for 2 Weeks
30 cognitively normal adults aged 60-85 will receive escitalopram 20mg for 2 weeks (upward titration as: 10mg for 5 days, then 20mg for 9 days); and amyloid beta levels in the CSF will be measured at baseline (before drug administration) and after 2 weeks of study drug (active or placebo). Participants will taper off medication following the 2nd CSF measurement.
Escitalopram 20mg for 2 weeks: 30 cognitively normal adults aged 60-85 will receive escitalopram 20 mg for 2 weeks; amyloid beta levels in the CSF will be measured at baseline (before drug administration) and following the full study drug (i.e., active drug) administration.
