Throughout much of its 250 year history, little if any mention has been made of ADHD being associated with Hoarding Disorder (HD). But starting 10-12 years ago, studies began to be reported of some linkage between ADHD in those with HD and of HD among people with ADHD. This is surprising given that HD has often been considered a variant of OCD (obsessive compulsive disorder) and is so classified in DSM-5, our diagnostic manual. The available evidence suggests that HD has a far more stronger linkage to ADHD than it does to OCD, calling into question the DSM5 classification of HD with OCD. it also finds that the best predictor of HD is the degree of inattention and executive dysfunction (self-regulation). This lecture reviews some of the more recent studies on this relationship as well as the limited research on the role of medications and other therapies in its management.
