This study consists of 2 parts, Part A and Part B. Part A is a single center, randomized, double-blind, placebo-controlled cohort designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of NMRA-323511 among healthy elderly. Part B is a multicenter, randomized, double-blinded, placebo-controlled, parallel-group cohort to evaluate the safety, tolerability, and efficacy of NMRA-323511 among adults with Agitation Associated with Dementia due to Alzheimer's Disease. Part A consists of a Screening Period (up to 28 days), a 10-day Treatment Period, and a 10- day Follow-up clinic visit after last dose of study treatment. Part B consists of a Screening Period (up to 28 days), an 8-week Treatment Period, and a 10-day Follow-up clinic visit after last dose of study treatment.
