Table 4. ICSD-3 diagnostic criteria for insufficient sleep syndrome.
1 If there is doubt about the accuracy of personal history or sleep logs, then actigraphy should be performed, preferably for at least two weeks.
2 In the case of long sleepers, reported habitual sleep periods may be normal based on age. However, these sleep periods may be insufficient for these patients.
