Name of journal: The Canadian journal of neurological sciences. Le journal canadien des sciences neurologiquesAbstract: We investigated the effects of transcranial alternating stimulation (tACS) in patients with insomnia. Nine patients with chronic insomnia underwent two in-laboratory polysomnography, 2 weeks apart, and were randomized to receive tACS either during the first or second study. The stimulation was applied simultaneously and bilaterally at F3/M1 and F4/M2 electrodes (0.75 mA, 0.75 Hz, 5-minute). Sleep onset latency and wake after sleep onset dropped on the stimulation night but they did not reach statistical significance; however, there were significant improvements in spontaneous and total arousals, sleep quality, quality of life, recall memory, sleep duration, sleep efficiency, and daytime sleepiness.All authors: Jeliazkov PG, Mete M, Motamedi GK, Nawar S, Oyegbile-Chidi TO, Sharma VD, Song SS, Turkeltaub PE, Won Cho Y, Wu JYFiscal year: FY2023 Digital Object Identifier:
