F. Hohagen et al., PREVALENCE OF INSOMNIA IN ELDERLY GENERAL-PRACTICE ATTENDERS AND THE CURRENT TREATMENT MODALITIES, Acta psychiatrica Scandinavica, 90(2), 1994, pp. 102-108
This study aimed to assess the prevalence and treatment modalities of
elderly practice attenders. A total of 330 patients aged over 65 years
were investigated with a questionnaire in general practice. To assess
insomnia, operationalized diagnostic criteria according to DSM-III-R
were applied. Twenty-three percent of the elderly patients suffered fr
om severe, 17% from moderate and 17% from mild insomnia. More than 80%
of the patients reported suffering from insomnia for 1-5 years or lon
ger, which indicates a chronic course. Elderly patients showed unreali
stic expectations concerning duration of sleep and spend more time in
bed than they realistically can expect to sleep. More than half of the
elderly patients reported habitual daytime napping. Sleep-disturbed e
lderly patients did not differ significantly from good sleepers in the
ir habit of taking daytime naps, but even when taking daytime naps, go
od sleepers slept significantly longer than the sleep-disturbed patien
ts. A significant association was found between insomnia and mental di
sorders, i.e., depression and organic brain syndrome according to the
diagnosis of the general physician. In about half of the cases the pri
mary care physician was not aware that the elderly patient suffered fr
om severe insomnia. More than half of the elderly severe insomniacs to
ok prescribed hypnotics habitually, mainly benzodiazepines.
