Covers orientation, memory, attention, executive function, and language. Scoring is adjusted for level of education.

AD8 — AD8 Dementia Screening Interview An 8-item informant interview that detects early cognitive change across multiple dementing illnesses including Alzheimer disease, vascular dementia, Lewy body dementia, and frontotemporal dementia. Can be administered to an informant or the patient directly.
