What Is REM behavior disorder caused by?

Etiology – Most cases of RBD are caused by alpha-synuclein neurodegeneration. RBD is also caused by antidepressant medications (table 1), narcolepsy, and pontine lesions such as those from stroke or multiple sclerosis.

How is RBD diagnosed?

Diagnosis of RBD involves a clinical interview in which history of dream enactment behaviors is elicited and a subsequent overnight polysomnography (PSG) evaluation to assess for REM sleep without atonia (RWA) and/or observe motor behaviors during REM sleep.

Can RBD be cured?

RBD can be treated with medication. However, it often occurs with other sleep problems or conditions, which may require additional treatment. If diagnosed, you should be monitored by your doctor. REM sleep behavior disorder may indicate a neurodegenerative disease or may be induced by some medications.

Does stress cause RBD?

As well, psychological stress often aggravates RBD symptoms.

What medications cause RBD?

Acute onset RBD is almost always induced or exacerbated by medications (especially Tri-Cyclic Antidepressants, Selective Serotonin Reuptake Inhibitors, Mono-Amine Oxidase Inhibitors, Serotonin Norepinephrine Reuptake Inhibitors,26 Mirtazapine, Selegiline, and Biperiden) or during withdrawal of alcohol, barbiturates.

Is there a cure for RBD?

RBD is an attractive target for future neuroprotective treatment trials to prevent evolution of overt parkinsonism or memory decline, but currently, there are no known effective treatments and future trials will be necessary to determine if RBD is an actionable time point in the evolution of overt synucleinopathy.

What does melatonin do for RBD?

Melatonin appears to be beneficial for the management of RBD with reductions in clinical behavioral outcomes and decrease in muscle tonicity during REM sleep.

What kind of doctor treats REM sleep disorder?
