Hoarding is not highly associated with eating disorders. The disorder does have a high rate of co-occurrence with depressive and anxiety disorders as well as with attention-deficit/hyperactivity disorder (ADHD). Indeed, the thought of discarding one's possessions can create intense anxiety in the hoarder. Hoarding disorder may also occur as part of obsessive-compulsive disorder (OCD), in which individuals have obsessions in relation to certain items and compulsions to collect these objects.
Hoarding can also occur as a part of organic states such as dementia, cerebrovascular accidents, or alcohol-related brain disorders. In these cases, the hoarding is relatively new in onset and much more disorganized, with more prominent squalor. As in chronic hoarding, patients typically lack insight into their disorder, making input from friends and neighbors critical to diagnosis. Medical review and examination is indicated for acute-onset cases.
