Today, some experts doubt that psychogenic amnesia is a real phenomenon, reasoning that there is either an undetected physical cause or the patient is fabricating their memory symptoms.
In a new paper in Brain, a team of British neuropsychologists has reported their findings from a study of 53 patients diagnosed with psychogenic amnesia – one of the largest ever studies of its kind.

The patients with psychogenic amnesia were all patients at St Thomas’s Hospital in London between 1990 and 2008, and the researchers compared their memory functioning and clinical history with 21 patients with memory disorders with a known physical cause (such as early stage Alzheimer’s or hypoxia), and 14 healthy volunteers.
