A 40 year old woman literally died of untreated Obsessive Compulsive Disorder after showering for up to 20 hours a day and finally refusing to eat. Her elderly parents struggled for help but now face involuntary manslaughter charges. Another disorder, Pica, is an appetite for non-nutritive substances like chalk, soap or even feces. One Florida womanâs addiction to soap has a happy ending.
