What is amnesia?
Amnesia refers to the loss of memories, such as facts, information and experiences.
People with amnesia — also called amnestic syndrome — usually know who they are. But, they may have trouble learning new information and forming new memories.
Amnesia can be caused by damage to areas of the brain that are vital for memory processing. Unlike a temporary episode of memory loss (transient global amnesia), amnesia can be permanent.
There's no specific treatment for amnesia, but techniques for enhancing memory and psychological support can help people with amnesia and their families cope.
Symptoms
The two main features of amnesia are:
- Difficulty learning new information
- Difficulty remembering past events and previously familiar information
Most people with amnesia have problems with short-term memory — they can't retain new information. Someone may recall experiences from childhood or know the names of past presidents, but not be able to name the current president, know what month it is or remember what was for breakfast.
People with amnesia usually can understand written and spoken words and can learn skills such as bike riding or piano playing.
They may understand they have a memory disorder.
Amnesia isn't the same as dementia.
