Crawford MR, et al. - In this proof-of-concept study, researchers examined the feasibility, acceptability, and preliminary efficacy of a digital cognitive behavioral therapy for insomnia (dCBT-I) for cases with chronic migraines (CM) and insomnia (CM-I) in the United States. They randomized 42 females with CM-I symptoms to receive dCBT-I after 2, 4, or 6 weeks of completing baseline sleep diaries. Of these women, 35 (83.3%) completed dCBT-I within the 12 weeks provided; 33 (94.3%) among these completers stated being satisfied (n = 16) or very satisfied (n = 17) with treatment. Furthermore, the treatment led to a response in 65.7% of completers that met the universally accepted criteria for insomnia. Lastly, reversion from CM to episodic migraine was reported in 34% of completers. Outcomes thereby support the feasibility and acceptability of dCBT-I in cases with CM-I complaints and suggest it as effective in improving insomnia and migraine symptoms.
