Understanding the mechanisms of arousal is a fundamental problem in neuroscience with high potential to impact numerous neurological diseases. The orexin (also called hypocretin) neuropeptide transmitter system critically orchestrates the activity of multiple brain circuits to produce sustained wake and motivation. Indeed, loss of orexin neurons of the hypothalamus causes the sleep-wake disorder narcolepsy with cataplexy. This disorder is characterized by uncontrollable attacks of sleep and attacks of muscle paralysis triggered by emotion. Loss or dysfunction of the orexin system may also play a role in sleepiness associated with Parkinson disease and traumatic brain injury (TBI). Using animal models, we have demonstrating that replacement of orexin into the brain by direct infusion or gene-bases therapy holds great potential for reversing the sleepiness associated with these disorders. Our research involves translating the use of orexin-based therapies and other neuromodulatory techniques (including deep brain stimulation) into surgical practice for the treatment of sleep attacks associated with narcolepsy or Parkinson disease, cataplexy, and minimally conscious state following TBI.
