Patients who are unable to get sound sleep at night are said to suffer from irregular sleep. Generally, affected patients only are only able to sleep for about 1 to 4 hours at a time, thereby requiring more than one sleeping session in a span of 24 hours. Although patients of this syndrome are not considered as sleep deprived, their sleep quality is generally poor and disrupted. The absence of circadian rhythm (changes that take place in the mental, behavioral and physical aspects in an individual in a 24 hour cycle) is generally the cause behind irregular sleep.
HOW IS IRREGULAR SLEEP DIAGNOSED?
