失眠症(insomnia)一词在一般的场合很常用。但普通所说的失眠,指的是不充分的睡眠或不完全的睡眠,并不意味着完全失眠状态。1979年由 ASDC(美国儿童牙科学会)和 APSS(睡眠精神生理研究协会)所提出的“睡眠、觉醒障碍诊断分类”,将失眠症定义为“睡眠的开始和持续的障碍”,并列举了各种病态(如表1)。入睡障碍多为神经性失眠,熟睡障碍多为抑郁病或脑器质性损害,中途觉醒多为睡眠时无呼吸失眠综合征,而清晨觉醒则为狂躁抑郁病等。 The term insomnia is commonly used on average. But commonly referred to as insomnia, referring to inadequate or incomplete sleep, does not mean completely insomnia. The “Diagnostic Classification of Sleep, Awakening Disorders” proposed by ASDC (American Society of Pediatric Dentistry) and APSS (Sleep Psychophysiological Research Association) in 1979 defines insomnia as “the onset and persistent disorder of sleep” and cites Morphology (Table 1). Sleep disorders are mostly neurological insomnia, mostly asymptomatic disorders of sleep or brain organic damage, midway awakening mostly sleep without respiratory insomnia syndrome, and early morning awakening is manic depression and so on.
