By Mayo Clinic staffHoarding is the excessive collection of items, along with the inability to discard them. Hoarding often creates such cramped living conditions that homes may be filled to capacity, with only narrow pathways winding through stacks of clutter. Some people also collect animals, keeping dozens or hundreds of pets in unsanitary conditions.
Hoarding, also called compulsive hoarding and compulsive hoarding syndrome, can be a symptom of obsessive-compulsive disorder (OCD). But many people who hoard don't have other OCD-related symptoms, and researchers are working to better understand hoarding as a distinct mental health problem.
People who hoard often don't see it as a problem, making treatment challenging. But intensive treatment can help people who hoard understand their compulsions and live a safer, more enjoyable life.
