Neuropsychiatric Presentations of Common Dementia Syndromes: A Clinical Review for Primary Care

This review examines neuropsychiatric symptoms (NPS) across four major dementia syndromes—Alzheimer's disease, vascular dementia, Lewy body dementia, and frontotemporal dementia—highlighting that these symptoms often emerge early or even precede cognitive decline. The article provides clinical guidance for primary care teams to recognize prodromal neurodegenerative disease and initiate appropriate diagnostic workup, addressing gaps in dementia training among frontline practitioners.
