Sleep deprivation
Sleep deprivation is also associated with ASC, and can provoke seizures due to fatigue. Sleep deprivation can be chronic or short-term depending on the severity of the patient's condition. Many patients report hallucinations because sleep deprivation impacts the brain. An MRI study conducted at Harvard Medical school in 2007, found that a sleep-deprived brain was not capable of being in control of its sensorimotor functions, leading to an impairment to the patient's self-awareness. Patients were also prone to be a lot clumsier than if they had not been experiencing sleep deprivation.
