Compulsive Hoarding: The Syndrome
Hoarding is part of a discrete clinical syndrome that also includes: Indecisiveness, perfectionism, difficulty in organizing tasks, avoidance. The prevalence of compulsive hoarding syndrome in the USA is estimated to be 600,000 to 1.2 million. This is a conservative estimate since hoarding behaviors are often kept in secret due to shame and embarrassment of disclosing.
