Dementia vs. Alzheimer's: The Key Differences
24 Jun
Summary
- Alzheimer's is a disease; dementia is a collection of symptoms.
- Alzheimer's is the most common cause of dementia.
- Dementia affects thinking, memory, mood, and behavior.
The primary distinction lies in definition: Alzheimer's is a progressive disease attacking the brain, whereas dementia describes a range of symptoms resulting from brain damage. Alzheimer's disease is the most frequent trigger for dementia, impacting cognitive abilities.
Dementia manifests as a decline in memory, thinking, and problem-solving skills, often accompanied by mood and behavioral changes. It is caused by various brain diseases, not a normal part of aging.
In the UK, an estimated 982,000 individuals are affected by dementia, with a significant portion undiagnosed. Alzheimer's disease accounts for about two-thirds of these cases.
Early Alzheimer's symptoms are subtle, allowing independence. However, as brain damage progresses, dementia symptoms become apparent. The disease typically begins in the memory-related brain regions, though variations exist.
