Efficacy of transcranial direct-current stimulation on chronic insomnia

The purpose of this study was to assess the effect and safety of transcranial direct current stimulation (tDCS) in primary chronic insomnia. A one-month, double-blind, randomized, sham-controlled trial was performed. A total of 7 patients with primary chronic insomnia received tDCS using anodal (n=3), cathodal (n=2) or sham stimulation (n=2). They were followed up at 1 week and 1 month after treatment. The primary outcome measures included improvement in total sleep time (TST), sleep latency (SL), and sleep efficiency (SE) at 1-month follow-up.
