Medscape (1/14, Brooks, Subscription Publication) reports that after “analyzing data on 4,322 adults,” investigators “have identified five novel subtypes of insomnia, which may lead to more personalized treatments for insomnia.” According to Medscape, these “subtypes are largely unrelated to sleep complaints but rather are differentiated by biologically based traits and life history.” What’s more, the subtypes “are stable over time and are associated with comorbid depression, treatment responses, and findings in encephalographic event–related potentials, the investigators” found. The findings were published online Jan. 7 in The Lancet Psychiatry. The author of an accompanying commentary observed the study “suggests that ‘robust subtyping is possible among a population with insomnia.’”
