Hoarding disorder (HD) is a psychiatric condition that negatively impacts individual sufferers, their families and the larger community. The disorder goes beyond problems with excessive clutter; it also presents with deficits in executive functioning, attachment and affect regulation deficits. This paper focusses on the needs of adult children of parents with HD, who directly experience the consequences of the disorder throughout their life cycle. We explore the existing research on the psychological, relational and social impact of parental hoarding on adult offspring. We discuss the clinical implications of these findings and offer possible psychological interventions that may be of help in this vulnerable population.
