“…Hoarding disorder (HD), only recently codified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5;American Psychiatric Association, 2013), has been linked with multiple risks to older adults, including medical problems, impairment in activities of daily living, and fire or falling hazards (Ayers, Iqbal, & Strickland, 2014;Ayers, Saxena, Golshan, & Wetherell, 2010;Ayers, Scheisher, Liu, & Wetherell, 2012;Ayers & Dozier, 2014). Although several papers have discussed the age of onset of compulsive hoarding (Grisham, Frost, Steketee, Kim, & Hood, 2006;Ayers et al, 2010) and hoarding symptoms in patients with obsessive compulsive disorder (Tolin, Meunier, Frost, & Steketee, 2010), none of the studies has examined the age of onset and progression of hoarding symptoms in older adults meeting DSM-5 criteria for HD.…”
