Psychogenic Balance Disorders: Is It a New Entity of Psychogenic Movement Disorders?

Psychogenic Balance Disorders: Is It a New Entity of Psychogenic Movement Disorders?

The various reported psychogenic dyskinesias include tremor, dystonia, myoclonus, gait disorder, Parkinsonism, tics, and chorea. It is not easy to diagnose psychogenic movement disorders, especially in patients with underlying organic disease. We describe three patients with balance and/or posture abnormalities that occur when they stand up, start to move, or halt from walking, although their g...

Psychogenic movement disorders.

PURPOSE OF REVIEW This review focuses on recent studies assessing clinical features and laboratory findings that may help diagnose psychogenic movement disorders, and the ongoing controversy about the relationship of these disorders with preceding peripheral injury. RECENT FINDINGS 'Organic' movement disorders may still be misdiagnosed as psychogenic. Probably more commonly, however, psychoge...

Imaging Psychogenic Movement Disorders

The neurobiological basis of psychogenic movement disorders (PMDs) has been elusive, and they remain difficult to treat. In the last few years, functional neuroimaging studies have provided insight into their pathophysiology and neural correlates. Here, we review the various methodological approaches that have been used in both clinical and research practice to address neural correlates of func...

Psychogenic Movement Disorders

Abnormal movements and postures resulting from primary psychiatric disease are a diagnostic dilemma because all types of movement disorders may be mimicked by a psychogenic disease, including akinetic-rigid and hyperkinetic disorders, with the latter more frequent, particularly tremor, myoclonus, and dystonia (Williams et al., 2005; Reich, 2006). Psychogenic movement disorders (PMDs), are a val...
