Not all dementia is the same — and many types don't start with memory loss the way most people expect. Alzheimer's is the type most people picture, and it usually does start with forgetfulness. But it's only one of over 100 types. In frontotemporal dementia, memory often stays intact early on, while personality, judgment, or language change first. In vascular dementia, the first sign is often trouble planning or slowed thinking. In Lewy body dementia, hallucinations, fluctuating alertness, or acting out dreams during sleep often come first.
