Key Differences
Amnesia often results from damage to the hippocampus or related areas, leading to difficulty in forming new memories or recalling past events, whereas dementia, such as Alzheimer's, involves widespread brain deterioration, impacting memory, reasoning, and daily functioning.
While amnesia may have a more abrupt onset and can sometimes be reversible, dementia typically progresses gradually and is irreversible.
Amnesia primarily affects memory, with preserved cognitive abilities, while dementia encompasses memory loss along with impairments in reasoning, language, and attention.
Treatments for amnesia focus on coping strategies and psychological support; in contrast, dementia management includes medications, lifestyle changes, and supportive care to slow progression and manage symptoms.
The impact on daily life differs, amnesia might involve specific memory gaps, whereas dementia leads to broad cognitive impairments, making independent living challenging.
