According to one meta-analysis of sleep disorders in children, confusional arousals and sleep walking are the two most common sleep disorders among children. An estimated 17.3% of kids between 3 and 13 years old experience confusional arousals. About 17% of children sleep walk, with the disorder being more common among boys than girls. The peak ages of sleep walking are from 8 to 12 years old. A different systematic review offers a high range of prevalence rates of sleep bruxism for children. '''Parasomnias like sleep walking and talking typically occur during the first part of a individuals sleep cycle, which is known as the first slow wave of sleep During this period of the sleep cycle your mind and body slows down causing you to feel drowsy and relaxed. At this stage it is the easiest for you to awake, therefore, many children do not remember what happened during this time. Nightmares are also considered another parasomnia among children,where they typically remember what took place. However, nightmares only occur during the last stage of sleep known as Rapid Eye Movement (REM) sleep. This is the deepest stage of sleep, it is known as REM because a individual can show a host of neurological and physiological responses which are similar to being awake. '''

Between 15.29 and 38.6% of preschoolers grind their teeth at least one night a week. All but one of the included studies reports decreasing bruxist prevalence as age increased as well as a higher prevalence among boys than girls.

By adulthood, parasomnias normally can be resolved due to a person's growth, however there is 4% of people have recurring symptoms. Another systematic review noted 7-16% of young adults suffer from delayed sleep phase disorder. This disorder reaches peak prevalence when people are in their 20s. Between 20 and 26% of adolescents report a sleep onset latency of greater than 30 minutes. Also, 7-36% have difficulty initiating sleep. Asian teens tend to have a higher prevalence of all of these adverse sleep outcomes than their North American and European counterparts.Sleep Disorders collectively refers to the effect of sleep quality, timing, and duration which can ultimately impact a person's ability to function.. Sleep is a fundamental necessity for a person's physical and mental health and an activity that is underrated by humans and mostly children. Sleep, the lack of,sleep. and its effects are one of the most talked about topics amongst parents and doctors during clinic visits.

Insomnia
'''Insomnia is a prevalent form of sleep deprivation. You may have problems getting asleep, staying asleep, or both if you have it. As a result, you may receive insufficient sleep or sleep of poor quality. When you wake up, you might not feel refreshed..''' Combining results from 17 studies on insomnia in China, a pooled prevalence of 15.0% is reported for the country. This is considerably lower than a series of Western countries (50.5% in Poland, 37.2% in France and Italy, 27.1% in USA). However, the result is consistent among other East Asian countries. Men and women residing in China experience insomnia at similar rates. A separate meta-analysis focusing on this sleeping disorder in the elderly mentions that those with more than one physical or psychiatric malady experience it at a 60% higher rate than those with one condition or less. It also notes a higher prevalence of insomnia in women over the age of 50 than their male counterparts.

A study that was resulted from a collaboration between Massachusetts General Hospital and Merck describes the development of an algorithm to identify patients with sleep disorders using electronic medical records. The algorithm that incorporated a combination of structured and unstructured variables identified more than 36,000 individuals with physician-documented insomnia.
