People with hoarding disorder exhibit symptoms of excessive attachment to their belongings and may feel uneasy allowing other people to borrow or touch their things, or apprehension at throwing away or disposing of any items, notes Mayo Clinic. The person may be unable to part with anything he owns, even if the item appears to be worthless, including magazines, junk mail, newspapers or items that seem useless or unnecessary, such as napkins from a restaurant or even trash.
The home of the hoarder may be seriously cluttered to the point that it is unlivable, notes Mayo Clinic. It may become impossible for the person and his family to even get through the home, or they may just have areas of the home that are livable, with access completely being blocked to a kitchen or bathroom. The person often lets trash pile up extensively, and the home falls into a state of squalor.
Hoarders often have a difficult time managing their daily living activities, and they may have difficulty making choices. They tend to procrastinate, and often just move items from one large pile to another when attempting to clean up their hoardes. They usually have limited social interactions, due to embarrassment and shame about their living quarters.
