Dissociative fugue (), formerly called a fugue state or psychogenic fugue, is a mental and behavioral disorder that is classified variously as a dissociative disorder, a conversion disorder, and a somatic symptom disorder. The disorder is a rare psychiatric phenomenon characterized by reversible amnesia for ones identity, including the memories, personality, and other identifying characteristics of individuality. The state can last for days, months or longer. Dissociative fugue usually involves unplanned travel or wandering and is sometimes accompanied by the establishment of a new identity. It is a facet of dissociative amnesia, according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). After recovery from a fugue state, previous memories usually return intact, and further treatment is unnecessary. An episode of fugue is not characterized as attributable to a psychiatric disorder if it can be related to the ingestion of psychotropic substances, to physical trauma, to a general medical condition or to dissociative identity disorder, delirium, or dementia. Fugues are precipitated by a series of long-term traumatic episodes. It is most commonly associated with childhood victims of sexual abuse who learn to dissociate memory of the abuse (dissociative amnesia). Signs and symptoms
Symptoms of a dissociative fugue include mild confusion and once the fugue ends, possible depression, grief, shame, and discomfort. People have also experienced a post-fugue anger. Another symptom of the fugue state can consist of loss of ones identity.
Crutch paralysis is a form of paralysis which can occur when either the radial nerve or part of the brachial plexus, containing various nerves that innervate sense and motor function to the arm and hand, is under constant pressure, such as by the use of a crutch. This can lead to paralysis of the muscles innervated by the compressed nerve. Generally, crutches that are not adjusted to the correct height can cause the radial nerve to be constantly pushed against the humerus. This can cause any muscle that is innervated by the radial nerve to become partially or fully paralyzed. An example of this is wrist drop, in which the fingers, hand, or wrist is chronically in a flexed position because the radial nerve cannot innervate the extensor muscles due to paralysis. This condition, like other injuries from compressed nerves, normally improves quickly through therapy. See also
