Dementia vs. Alzheimer’s: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on August 10, 2024
Dementia is a broad term for cognitive decline, encompassing various conditions including Alzheimer's, which is the most common cause of dementia, characterized by memory loss and cognitive impairment.
Key Differences
Dementia is an umbrella term for a range of cognitive impairments, affecting memory, thinking, and social abilities. Alzheimer's is a specific disease under this umbrella, characterized by progressive memory loss and cognitive decline.
Dementia can result from various causes, not limited to Alzheimer's, and can affect individuals differently. Alzheimer’s is the most common cause of dementia, accounting for 60-80% of cases, typically appearing in individuals over 65.
Symptoms of dementia vary but generally include memory loss, difficulty in thinking, problem-solving, and language challenges. Alzheimer’s starts with mild memory loss, eventually leading to significant impairment in cognitive and daily functioning.
Dementia can be caused by Alzheimer's disease, vascular issues, Lewy body dementia, and more. Alzheimer's is believed to result from abnormal brain protein deposits, although the exact cause is still researched.
There's no cure for dementia, treatments focus on symptom management and improving quality of life. Alzheimer's treatments include medications for memory loss and therapies to manage behavioral changes.
