[CHARACTERISTICS AND DIFFERENTIAL DIAGNOSTICS OF SLEEP RELATED PATHOLOGICAL MOVEMENTS. UPDATE 2013]

Wide variety of the movements (from the physiologic body position changes to different pathologic events) can be seen during the sleep period. The most important types of these movements are the sleep related events (from the parasomnias to the restless leg related movements), the movement disorders and the epilepsy related events. To differentiate between these events is required special skill, which is based on appropriate characterisation of the events (for example timing, repetition, pattern), the polysomnographic and video-EEG examination and validated questionnaires (FLEP scale). The appropriate differential diagnostics and therapy must be based on the knowledge of the relationship of the sleep architecture and movement events. This review would like to provide guideline for the understanding and recognizing the nature of the sleep related movements.
