`Although hoarding has been studied in adults, little is known about proble
ms of hoarding by elderly people. This study used a structured telephone in
terview, with elder services providers to investigate hoarding behaviors ii
i relation to functional impairment, cognitive deficits, and physical and p
sychological conditions in 62 elderly clients. Most elderly hoarders were f
emale unmarried and lived alone. Extensive clutter was associated with sign
ificant impairment, interfering with basic hygiene, and posing a serious ph
ysical threat for many, elderly clients. Clients were rarely insightful abo
ut their collecting and often resisted change, rendering interventions gene
rally ineffective. Never-married status was associated with more severe hoa
rding and greater impairment and possibly with worse outcomes of interventi
on efforts. Health and mental health implications of hoarding by elderly pe
ople and implications for treatment are discussed.
