title: Case report of adjunctive use of olanzapine with an antidepressant to treat sleep paralysis.
abstract: Sleep paralysis (SP) is a condition of unknown etiology that usually occurs when falling asleep or when awakening in which the individual remains conscious but is unable to control their voluntary movements. This case report is about a 68-year-old man with a 40-year history of symptoms of SP and associated panic attacks upon awakening. Neurological examination and neuroimaging identified no abnormalities. Five years before the current evaluation he had been diagnosed with depression and treated with various anti-depressants which ameliorated, but did not cure, his SP. However, this 40-year history of SP was abruptly terminated - and did not return over the subsequent two years - after adjunctive treatment with 2.5 mg olanzapine each night was added to his antidepressant.
