Residual symptoms after natural remission of insomnia: associations with relapse over 4 years.

ABSTRACT: Chronic insomnia tends to "wax and wane" over lifetime. The presence of residual insomnia symptoms is common, especially among naturally remitted individuals. This study aims to examine the features of these residual symptoms and their potential association with future relapse. A population-based data set on the natural history of insomnia was used for this secondary analysis.

The nature and severity of residual symptoms were examined with an extended versio
