Factitious disorder, often referred to as Munchausen’s syndrome, is a condition in which sufferers present to healthcare professionals seeking investigation and treatment for signs and symptoms that they have consciously fabricated for no obvious reason. Factitious presentations have been described all over the world, in every medical specialty and in every age group, yet by its very nature factitious disorder is difficult to study. There is therefore a dearth of evidence in the literature relating to epidemiology, aetiology and therapeutics.
Functional neurological symptoms refer to neurological symptoms that are not explained by disease. They may also be called psychogenic, nonorganic, somatoform, dissociative or conversion symptoms. The most common functional neurological symptoms are non-epileptic attacks and functional weakness. These are common in neurology and general medical practice, especially in emergency situations, where they can be mistaken for epilepsy or stroke.
