Sleep/Wake Disturbances in Mild Traumatic Brain Injury Patients

2012 
The continued research and practice of sleep medicine has provided insights into brain physiology, novel diagnostic tools, and innovative treatment options for poorly understood diseases. Sleep is broken down into a circadian rhythm pattern characterized by the three stages: maintenance mechanisms of the NREM cycle and the oscillation of phasic and tonic movements in the REM cycle. Recently, traumatic brain injury has been shown to negatively impact these normal sleep/wake cycles and to increase significantly the risk of comorbid disease. The link between TBI and sleep disorders has been established through the use of subjective measures of sleep disturbance such as the Pittsburgh Sleep Quality Index and through objective analysis like polysomnography. Case studies demonstrate that clinicians’ use of these types of assessments creates a more complete medical picture and treatment plan for TBI patients.
