发作性睡病几乎是一种终身疾病。几乎一半的发作性睡病患者日常生活备受白天过度嗜睡(EDS) 和/或猝倒困扰损害。[108]Roy A. Psychiatric aspects of narcolepsy. Br J Psychiatry. 1976 Jun;128:562-5.http://www.ncbi.nlm.nih.gov/pubmed/1276566?tool=bestpractice.com
虽然有少数发作性睡病患者通过非药物策略成功抵抗睡眠过度,但是大部分的患者仍需要药物治疗。尽管使用药物,日间表现也很少能正常化。[111]Mitler MM, Aldrich MS, Koob GF, et al. Narcolepsy and its treatment with stimulants. ASDA standards of practice.
