Amnesia – Symptoms and causes – Mayo Clinic

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.
