The occurrence of parasomnias, which are most common during childhood, is one probable early sign of psychosis vulnerability. 6–8 Frequent nightmares have long been thought to play a role in the development of psychosis. In the outpatient clinics, sleep problems are one of the most common presentations. In fact, maladaptive sleep patterns are linked to up to 50% of major complaints in primary care settings. The etiology of parasomnias is unknown because no obvious cause has been identified; nonetheless, a variety of explanations have developed.

As a result, reassuring and educating the parents can be beneficial in those situations without the need for medical assistance. With that being said there’s also serval medical approaches that address such a disease. In this article we will be looking at the disease epidemiology, etiology, diagnosis and treatment.
