Everybody has heard the statements “she’s a pack rat” or “he’s a hoarder,” but how many of us really know what that means? Pathological hoarding was first formally conceptualized as a syndrome separate from OCD in the early 1990s, yet it wasn’t until 2013 that hoarding received formal psychiatric diagnostic criteria in the DSM.How can a mental health professional who sees clients in an office determine if hoarding is a factor in a client’s life? Here, Carol Mathews provides readers with the first-ever comprehensive clinical book on hoarding, covering every aspect of the disorder. Topics include: epidemiology and impact; screening tools and clinical interview tools for assessment; differential diagnosis and co-occurring disorders; when to suspect mild cognitive impairment and dementia; hoarding behaviors in children; how to differentiate normal keeping of items from hoarding; animal hoarding; the neurobiology of hoarding disorder; treatments, both psychopharmacological and otherwise; self-help options; and the impact of hoarding on the family.
