A systematic review found that traumatic childhood experiences, such as family conflict or sexual trauma, significantly increase the risk of several sleep disorders in adulthood, including [[sleep apnea]], [[narcolepsy]], and [[insomnia]].<ref>{{cite journal |vauthors=Kajeepeta S, Gelaye B, Jackson CL, Williams MA |date=March 2015 |title=Adverse childhood experiences are associated with adult sleep disorders: a systematic review |journal=Sleep Medicine |volume=16 |issue=3 |pages=320–330 |doi=10.1016/j.sleep.2014.12.013 |pmc=4635027 |pmid=25777485}}</ref>

An evidence-based synopsis suggests that idiopathic REM sleep behavior disorder (iRBD) may have a hereditary component. A total of 632 participants, half with iRBD and half without, completed self-report questionnaires. The study results suggest that people with iRBD are more likely to report having a first-degree relative with the same sleep disorder than people of the same age and sex who do not have the disorder.<ref>{{cite journal |vauthors=Schenck CH |date=November 2013 |title=Family history of REM sleep behaviour disorder more common in individuals affected by the disorder than among unaffected individuals |journal=Evidence-Based Mental Health |volume=16 |issue=4 |pages=114 |doi=10.1136/eb-2013-101479 |pmid=23970760 |s2cid=2218369}}</ref> More research is needed to further understand the hereditary nature of sleep disorders.

A population susceptible to the development of sleep disorders includes people who have experienced a [[Traumatic brain injury|traumatic brain injury (TBI)]]. Due to the significant research focus on this issue, a systematic review was conducted to synthesize the findings. The results indicate that individuals who have experienced a TBI are most disproportionately at risk for developing narcolepsy, obstructive sleep apnea, excessive daytime sleepiness, and insomnia.<ref>{{cite journal | vauthors = Mathias JL, Alvaro PK | title = Prevalence of sleep disturbances, disorders, and problems following traumatic brain injury: a meta-analysis | journal = Sleep Medicine | volume = 13 | issue = 7 | pages = 898–905 | date = August 2012 | pmid = 22705246 | doi = 10.1016/j.sleep.2012.04.006 }}</ref>
