Picture-Based Memory Impairment Screen for Dementia

Objectives To develop and validate a picture‐based memory impairment screen (PMIS) for the detection of dementia. Design Cross‐sectional. Setting Outpatient clinics, Baby Memorial Hospital, Kozhikode city in the southern Indian state of Kerala. Participants Three hundred four community‐residing adults aged 55 to 94 with a mean education level of 8 years; 65 were diagnosed with dementia.
