Overview
Amnesia is different from normal forgetfulness. A person may be unable to remember new information, past events, or both. General intelligence and personality usually remain intact.
Symptoms
- Difficulty learning new information
- Difficulty recalling past events or familiar information
- Confusion or disorientation
- False memories (confabulation) in some types
Causes and risk factors
Causes include head injury, stroke, brain infection, lack of oxygen to the brain, seizures, long-term alcohol misuse with vitamin B1 deficiency, certain medicines and severe emotional stress.
Diagnosis
Assessment includes a history, memory and thinking tests, blood tests and brain imaging such as MRI. EEG may be used if seizures are suspected.
Treatment
Treatment addresses the cause, such as thiamine for vitamin deficiency. Memory training, occupational therapy and memory aids help people manage daily life.
When to see a doctor
Seek urgent medical care for sudden memory loss, especially after a head injury or with confusion, weakness or seizures. See a doctor for memory problems that develop gradually.
