ICSD-3. Sleep disorders re-classified

The third edition of the American International Classification of Sleep Disorders was published March 2014. There are significant changes in the sections on insomnia (inability to sleep appropriately) and parasomnias (unwanted behaviours during sleep).

Whereas the 2nd edition of ICSD distinguished between primary and secondary (sleeplessness arising from other conditions) insomnias and had numerous subtypes (e.g. psychophysiological insomnia, idiopathic, etc), the 3rd edition committee has removed these distinctions. Insomnia has now become a condition in its own right which may also be comorbid with other conditions. The subtypes have also been collapsed and insomnia, roughly, is divided into chronic and short-term.

Similarly the subtypes of the deep sleep parasomnias have also been simplified (e.g. confusional arousals in bed, turning into sleepwalking once the sleeper leaves the bed).
