The diagnosis of insomnia disorder is comparable across the two classification systems, but for patients who do not meet the full criteria, the two systems have different labels. 2 Table 1 outlines the similarities and differences between the two classification systems. There are two separate classification systems for sleep disorders, the International classification of sleep disorders, 3rd edition (ICSD-3) 1 and the Diagnostic and statistical manual for mental disorders, 5th edition (DSM-5). Insomnia is characterised by self-reported poor sleep quality or inadequate sleep despite adequate sleep opportunity and sleep-conducive environment, and it is accompanied by impairment to daytime function.
