Dementia is an umbrella term for a decline in memory, thinking, or other cognitive skills that is serious enough to interfere with daily life. Alzheimer's disease is one cause of that decline, not a synonym for every form of dementia. This page is educational only. It does not diagnose any person and it does not recommend a treatment.

Why the Distinction Matters for Care Planning
The distinction among dementia types matters for care planning because each condition can change memory, language, behavior, movement, sleep, and safety in a different order. A plan built only around forgetfulness may miss impulsivity, visual misperceptions, swallowing difficulty, or a sudden stepwise change after a vascular event.
Clearer language about the suspected type also helps families describe observations to a clinician and choose the intensity of help. Companion time, hands-on personal care, overnight coverage, and planned respite do not look the same in every household.
Alzheimer's Disease and Dementia Are Not the Same
Alzheimer's disease is a specific brain disease and the most common cause of dementia, while dementia itself is the broader set of symptoms that can have several causes. According to the CDC overview of Alzheimer's disease and dementia, Alzheimer's is the most common type of dementia.
In many people, early changes involve short-term memory, new learning, and orientation to time or place. Over time, language, judgment, and the ability to complete familiar tasks may also decline. Those patterns are why specialized memory care at home often emphasizes cues, consistent routines, and a calm environment rather than a single generic schedule.
Vascular Dementia
Vascular dementia is dementia related to reduced or interrupted blood flow in the brain, often in the setting of stroke or other vascular disease. Changes may appear more suddenly or in a stepwise pattern, and thinking problems can include slowed processing, difficulty with planning, or trouble with attention, not only memory loss.
Care planning may need to account for mobility limits, fall risk, and recovery after a hospital stay. Families sometimes add hospital discharge care when a vascular event or other admission leaves someone weaker at home than they were before.
Lewy Body Dementia
Lewy body dementia is a type of dementia associated with abnormal protein deposits in the brain and is often described with fluctuating alertness, recurrent visual hallucinations, sleep disturbance, and movement changes. Memory may be less prominent at first than attention, visuospatial skills, or day-to-day swings in how clear someone seems.
Because alertness and mobility can change within a single day, families often plan closer supervision, a simpler environment, and enough staffing to respond when symptoms spike. Overnight restlessness is one reason some households later consider 24-hour live-in care rather than daytime help alone.
Frontotemporal Dementia
Frontotemporal dementia is a group of conditions that mainly affect the frontal and temporal lobes and often change personality, behavior, or language before short-term memory is obviously impaired. A person may act impulsively, lose social filters, repeat certain actions, or struggle to find words while still recalling recent events.
Those differences matter at home because safety issues can involve judgment and behavior more than lost keys or missed appointments. Companion care that provides calm structure and redirection, along with help from personal care aides for bathing, dressing, and meals, can be more relevant than memory drills.
