Hoarding is a behaviour considered to be related to obsessive-compulsive disorder (OCD), characterized by a difficulty in discarding objects. This can result in excessive clutter.
Dennis lives in a decent sized apartment, yet he has no room for his new belongings. He has great difficulty parting with the newspapers, packaging and other inanimate objects that he has collected over the years, for fear that he might need to use them one day. He still keeps boxes of photographs, report cards and letters because they are sentimental. He has a hard time not picking up items on the curb that could be fixed and put to some use. His apartment is full. He is unable to use his living room, and no longer invites friends or family to visit. He doesn t like living this way, but the idea of changing his habits fills him with anxiety.
