Weighted blankets for insomnia in affective disorder and ADHD – a clinical follow up study
Introduction: Weighted blankets are used for the treatment of insomnia in patients with affective disorders and ADHD, despite the lack of scientific support. This study aimed to evaluate the clinical use of weighted blankets for insomnia in patients with affective disorder and ADHD. Methods: 199 psychiatric patients with affective and ADHD diagnoses and co-occurring insomnia were included consecutively and treated with weighted blankets as a part of a clinical routine. They were evaluated before and after four weeks use of the blanket concerning time to sleep onset and ten sleep-related symptoms, using a self-rating scale, and after one year by a telephone interview.Results: The use of weighted blankets reduced the median time to fall asleep from 70 to 30 minutes (p<0.001) and led to a significant improvement of ten other sleep-related symptoms at the follow up after four weeks. After one year the positive effects on sleep were still maintained.Conclusions: The favourable results the results of this open clinical study should be interpreted with caution. Studies with a controlled design are warranted.
