It’s been well documented in medical journals for years that those who suffer brain injury often complain of sleep disturbances. True, loss of sleep after a traumatic brain injury, may in part be due to the associated pain or anxiety following such incidents. However, medical studies clearly indicate that loss of sleep after a traumatic brain injury is often due the brain’s inability to properly produce melatonin after severe trauma.
In 2010, the American Academy of Neurology published studies researched by Dr. Rajaratnam, a leading physician studying the links between loss of sleep and brain injury. He reported that the results from the study “suggest that the brain injury may disrupt the brain structures that regulate sleep, including the production of melatonin”. Simply put, lack of melatonin production in the brain results in sleep loss.
