Amnesia vs. Dementia: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 21, 2024
Amnesia is the loss of memories or inability to form new ones, while dementia is a broader decline in mental function, often including memory loss.
Key Differences
Amnesia primarily involves memory loss or difficulty in forming new memories. Dementia, on the other hand, encompasses a broader range of cognitive impairments, including memory loss, but also affecting reasoning, communication, and problem-solving abilities.
Amnesia is often caused by brain injury, trauma, or diseases affecting the brain. Dementia can be caused by various conditions, including Alzheimer's disease, vascular issues, and progressive neurological disorders.
Amnesia, depending on its cause, may be reversible or stable. Dementia generally involves a progressive decline in cognitive functions, often worsening over time.
Amnesia can occur at any age, often related to specific events or injuries. Dementia is more common in older adults, though early-onset forms exist.
Treatment for amnesia focuses on coping strategies and addressing the underlying cause. Dementia treatment involves managing symptoms, slowing progression, and providing supportive care.
