• Hypertension that is poorly controlled or managed

• Any medical or neurological/neurodegenerative condition (other than AD) that, in the opinion of the Investigator, might be a contributing cause to the participant's cognitive impairment or could lead to discontinuation, lack of compliance, interference with study assessments, or safety concerns
