Compulsive buying disorder (CBD) is characterized by an obsession with shopping and buying behavior that causes adverse consequences. It "is experienced as a recurring, compelling and irresistible–uncontrollable urge, in acquiring goods that lack practical utility and very low cost[1] resulting in excessive, expensive and time-consuming retail activity [that is] typically prompted by negative affectivity" and results in "gross social, personal and/or financial difficulties".[2] Most people with CBD meet the criteria for a personality disorder. Compulsive buying can also be found among people with Parkinson's disease[3] or frontotemporal dementia.[4][5]
Compulsive buying-shopping disorder is classified by ICD-11 among "other specified impulse control disorders".[5] Several authors have considered compulsive shopping rather as a variety of dependence disorder.[6]
