What is the biggest difference between Alzheimer’s and dementia?

Alzheimer’s disease and dementia are related but distinct concepts. Dementia is a general term that describes a decline in cognitive ability severe enough to interfere with daily life, while Alzheimer’s disease is a specific type of dementia that accounts for a large portion of dementia cases. The biggest difference between Alzheimer’s and dementia is that Alzheimer’s disease is a specific and progressive neurological disorder that affects memory, thinking, and behavior, and eventually leads to the inability to carry out everyday activities. Dementia, on the other hand, is a broader term that encompasses a range of conditions characterized by cognitive decline, including Alzheimer’s disease, vascular dementia, Lewy body dementia, and others. In essence, Alzheimer’s disease is a type of dementia, but not all dementia cases are due to Alzheimer’s disease.
