Abstract:
The authors report the case of a 60-year-old man with acromegaly, who developed narcolepsy 2 weeks after completing radiotherapy for a pituitary adenoma. Cataplexy and sleepiness were predominant symptoms. Onset of narcolepsy is unusual at this age and the temporal relationship following radiotherapy suggests this treatment was implicated. His CSF hypocretin levels were normal, indicating other factors may be important in his narcolepsy.
