Confabulation

Confabulation is a symptom characterized by the involuntary fabrication of memories. It generally presents as a person making up stories or details in response to questions. It can manifest as a repetition of a false story or as a false belief that the person holds. It often develops as a result of brain damage, but can also be caused by psychiatric conditions such as schizophrenia. Symptoms of confabulation can range from minor details to larger stories, and can be difficult to distinguish from actual memories.
