Phenomenology of childhood hoarding

Abstract Hoarding disorder (HD) has been recently added as a separate diagnostic category in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. HD is a common and disabling disorder, with an estimated prevalence in the general population of 2–6%. Although evidence suggests that the onset of hoarding symptoms is usually during childhood and adolescence (youth), relatively little is known about HD in this population. The present article is a selective review of emerging literature on the clinical features of hoarding in youth.
