ABSTRACT
Sleep disorders are common clinical manifestations of brain traumas. For example, many patients who have sustained mild brain traumas complain of insomnia or excessive daytime sleepiness. Also, the most severely injured patients may have different sleep disorders as part of their clinical picture. Sleep disorders can be part of both the acute and the chronic behavioral consequences of traumatic brain injuries (TBI). In the latter case, they may be a symptom of a well-defined clinical condition, such as an anxiety disorder, a mood disorder or a psychotic disorder. In some cases, sleep and wakefulness disturbances are the primary complaint or one of the most important ones presented by a patient with a TBI.
