The Association Between Sleep and Late Life Hoarding.

Sleep problems are associated with many different forms of psychopathology in late life; however, there is currently a gap in the literature on the association between sleep quality and hoarding in older adults. This secondary data analysis of 40 older adults with hoarding disorder examined the association between sleep and hoarding, change in sleep disturbance following treatment, and the impact of sleep on treatment response. Sleep disturbance was correlated with hoarding severity, and this association remained significant when controlling for inability to sleep in a bed due to clutter in a multiple regression analysis. Following treatment, there was no change in sleep disturbance using a paired t-test, and baseline sleep disturbance was not correlated with change in hoarding severity. Future studies on the potential impact of sleep disturbance on hoarding treatment in older adults should examine if targeting sleep issues adjunctively could lead to improved sleep and improved treatment adherence/efficacy.
