Rhythmic movement disorder
Rhythmic Movement Disorder
Rhythmic Movement Disorder (RMD) is a neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was first described in the medical literature by Zappert as early as 1905.
Pronunciation
Rhythmic: /ˈrɪðmɪk/ Movement: /ˈmuːvmənt/ Disorder: /dɪˈsɔːrdər/
Etymology
The term "Rhythmic Movement Disorder" is derived from the Greek words "rhythmos" (meaning repeated, regular motion), "kinesis" (meaning movement), and "disorder" (from the Latin "dis" and "ordo", meaning "apart from" and "order" respectively).
Symptoms
The primary symptom of RMD is repetitive, rhythmic movement of the body, particularly the head and neck, during sleep. These movements can be violent and may lead to injury. Other symptoms may include sleep disruption and daytime sleepiness.
Causes
The exact cause of RMD is unknown, but it is thought to be related to neurological abnormalities or damage, and may be exacerbated by stress or anxiety.
Treatment
Treatment for RMD often involves behavioral interventions, such as relaxation techniques and changes in sleep hygiene. In some cases, medication may be prescribed to reduce the severity of the movements or to help with sleep disruption.
