Patients with essential tremor (ET) frequently experience sleep disorders, including poor sleep quality and daytime sleepiness. Polysomnography studies in ET patients are limited, hindering definitive conclusions on sleep characteristics.
Area of Science:
- Neurology
- Sleep Medicine
Background:
- Sleep disorders are common in patients diagnosed with essential tremor (ET).
- Understanding these sleep disturbances is crucial for comprehensive patient care.
Purpose of the Study:
- To review sleep disorders and polysomnographic findings in essential tremor patients.
- To systematically analyze existing literature on ET and sleep disturbances.
Main Methods:
- Systematic literature review using PubMed, EMBASE, MEDLINE, and Web of Science.
- Search terms included "essential tremor" combined with sleep-related terms and specific sleep disorders.
- Analysis guided by PRISMA and MOOSE guidelines.
Main Results:
- Most frequent complaints in ET patients include poor sleep quality and excessive daytime somnolence.
- Other reported issues include probable REM sleep behavior disorder, restless legs syndrome, insomnia, and nocturia.
- Meta-analyses indicate higher Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale scores in ET patients compared to controls.
Conclusions:
- Essential tremor patients frequently report sleep disturbances, notably poor sleep quality and daytime somnolence.
- Current polysomnography data for ET is insufficient to draw firm conclusions on specific sleep features.
- Further research is needed to elucidate the polysomnographic characteristics of sleep disorders in essential tremor.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
