Overview
Amnesia is a condition characterized by partial or complete loss of memory. It can affect the ability to recall past experiences (retrograde amnesia) or form new memories (anterograde amnesia). Amnesia results from brain injury, disease, psychological trauma, or other neurological conditions.
What is Amnesia?
Amnesia is the impairment of memory caused by damage or disruption to brain areas responsible for storing and retrieving memories. It may be temporary or permanent and can vary in severity. Amnesia is not a disease itself but a symptom of underlying brain dysfunction.
