What is the difference between dementia and Alzheimer's?
Dementia and Alzheimer's disease are related terms but not interchangeable. Here's an explanation of the difference between the two:
Dementia is a general term that describes a set of symptoms affecting cognitive functions such as memory, thinking, and reasoning. It is not a specific disease but rather a syndrome caused by various underlying conditions. Dementia can be caused by different factors, including Alzheimer's disease, vascular disorders, Parkinson's disease, Lewy body dementia, frontotemporal dementia, and others. The common feature of all types of dementia is a decline in cognitive abilities that interferes with daily functioning.
Alzheimer's disease, on the other hand, is the most common cause of dementia, accounting for 60-80% of all cases. It is a progressive neurological disorder that primarily affects older adults. Alzheimer's disease is characterized by the accumulation of abnormal protein deposits (amyloid plaques and tau tangles) in the brain, leading to the gradual destruction of brain cells and the subsequent decline in cognitive function. Memory loss, confusion, and difficulty with language and problem-solving are some of the early symptoms of Alzheimer's disease.
