Is Insomnia Associated with Deficits in Neuropsychological Functioning? Evidence from a Population-Based Study

摘要: Study Objectives: People with insomnia complain of cognitive deficits in daily life. Results from empirical studies examining associations between and impairment, however, are mixed. Research is needed that compares treatment-seeking community-based study samples, measures subjective as well objective functioning, considers participants’ pre-insomnia function. Design Participants: We used data the Dunedin Study, a representative birth cohort 1,037 individuals, to examine whether early midlife was associated functioning. also tested individuals who reported seeking treatment for their sleep problems (treatment-seekers) showed greater impairment than other (non-treatmentseekers). The role key confounders, including childhood ability comorbid health conditions, evaluated. Measurements: Insomnia diagnosed at age 38 according DSM-IV criteria. Objective neuropsychological assessments included WAIS-IV IQ test, Wechsler Memory Scale, Trail-Making Test. Childhood functioning assessed using Intelligence Scale Children-Revised (WISC-R). Results: A total 949 members were symptoms 38. Although (n = 186, 19.6%) had peers 38, they did not exhibit on formal testing. Treatment-seekers, exhibited significant compared non-treatment-seekers. Controlling comorbidity, daytime medications slightly decreased this association. antedated adult treatment-seekers. Conclusions: Links may be strongest among seek clinical treatment. Clinicians should take into account presence complex lower premorbid function when planning patients.
