While it is true that Alzheimer’s can develop into dementia, not all people with dementia will have Alzheimer’s and vice-versa. The symptoms are significantly similar, and it is easy to confuse these terms.
A simple way to understand its difference is that:
Dementia is the decline of memory and reasoning, while Alzheimer’s is a specific brain disease that affects many people who have dementia.
The best way to get an accurate diagnosis is to attend to a specialist. The doctor will perform several examinations to evaluate memory impairment, cognitive abilities, and behavioral abnormalities.
