+ | |||
+ | Sleep [[disorder]]s affect more than 10% of the population. | ||
+ | |||
+ | Sleep disordered breathing affects about 20% of community people above age 65 | ||

+ | Sleep disorders include: | ||
+ | |||
+ | [[Sleep apnea]] (periodic interruption of breathing) | ||
+ | |||
+ | Insomnia | ||
+ | |||
+ | Parasomnias | ||
+ | |||
+ | [[Rapid eye movement sleep behavior disorder]] | ||
+ | |||
+ | [[Narcolepsy]]. | ||
+ | |||
+ | ===== Etiology ===== | ||
+ | |||
+ | Traumatic brain injury (TBI) can cause sleep-wake disturbances and excessive daytime sleepiness. The pathobiology of sleep disorders in TBI, however, is not well understood, and animal models have been underused in studying such changes and potential underlying mechanisms. | ||
+ | |||
+ | Skopin et al. used the rat lateral fluid percussion (LFP) model to analyze sleep-wake patterns as a function of time after injury. Rapid-eye movement (REM) sleep, non-REM (NREM) sleep, and wake bouts during light and dark phases were measured with electroencephalography and electromyography at an early as well as chronic time points after LFP. Moderate TBI caused disturbances in the ability to maintain consolidated wake bouts during the active phase and chronic loss of wakefulness. Further, TBI resulted in cognitive impairments and depressive-like symptoms, and reduced the number of orexin-A-positive neurons in the lateral hypothalamus | ||
