Abstract
Late life insomnia is associated with worse cognitive performance. Behavioral/cognitive behavioral treatments for insomnia (BBT-I, CBT-I) improve sleep in older adults, but findings are mixed for cognition. This presentation examines the effects BBT-I and CBT-I on sleep and cognition across three RCTs involving older individuals (community-dwelling [N=62, Mage=69.45(SD=7.71)], chronic pain [N=64, Mage=53.2 (SD=13.7)], dementia caregiving [N=36, Mage=62.32 (SD=6.71]). Sleep was assessed using daily diaries and actigraphy for 1-2 weeks prior to randomization to treatment or control. Cognition was measured using standardized executive functioning, memory, and attention measures. Multiple regressions revealed improved executive functioning following treatment (caregivers), associations between improved executive performance and greater pain/sleep improvements (chronic pain), and associations between improved attention and processing speed and improved sleep 9-months following treatment (community-dwelling). BBT-I/CBT-I hold promise for improving cognition in older aged individuals with insomnia. Research is needed to determine what factors influence/which patients are most likely to experience cognitive benefits.
Highlights
Symptoms of insomnia are associated with symptoms of depression and anxiety in older adults, yet less is known about the impact of specific forms of insomnia (i.e. onset, maintenance, and terminal insomnia)

Summary
Symptoms of insomnia are associated with symptoms of depression and anxiety in older adults, yet less is known about the impact of specific forms of insomnia (i.e. onset, maintenance, and terminal insomnia). This study represents a secondary data analysis of older adults who received 26 sessions of group behavioral treatment for hoarding disorder (n = 41; mean age 64, range 55-85). No significant change in sleep disturbance was reported following completion of treatment and baseline sleep disturbance was not significantly predictive of change in hoarding symptom severity. Findings suggest that disturbed sleep quality is associated with greater hoarding symptom severity but does not preclude positive symptom change in treatment.
