Two disorders that are part of the OCD spectrum are hair-pulling disorder (left photo) and hoarding (right photo). People with hair-pulling disorder may feel so persistently compelled to pull their hair that they develop noticeable bald patches. Similarly, people who hoard feel unable to throw away objects even when the clutter is potentially life-threatening. Some people who compulsively hoard have died in fires in their homes because the hoarded objects took up so much space that it was difficult to leave once a fire started, or firefighters had to spend too much time trying to get into the house (Kaplan, 2007a). The woman in this photo found a cat amongst the clutter.
