Abstract
This article will review the evidence of various proposed factors that contribute to the onset and maintenance of hoarding disorder (HD). Data suggests that hoarding is a chronic condition that starts early in life and does not remit if left untreated. There is emerging evidence that a number of factors contribute to the expression of HD symptoms, including genetics, neurocognitive functioning, attachments to possessions, beliefs, avoidance, personality factors, and life events. The extent to which each etiological factor uniquely contributes to hoarding is still unknown. Other demographic factors, such as socioeconomic status, age, and gender, may impact hoarding severity. Research on the causes and characteristics of hoarding has recently started making progress into understanding this newly recognized disorder, yet we still have a ways to go in understanding the biological and environmental causes. This paper will synthesize available literature on the etiology of HD.
