Have you ever watched the TV show called Hoarders? I like watching it although I can't relate as I am not a hoarder but it let me understand what triggers their hoarding behavior. According to the psychologists that work with those hoarders, they said that hoarding is a mind disease. It is usually cause by a traumatic accident and becomes an addiction. I can't watch some of the hoarders though as some of them are filthy it makes you feel sick to your stomach if you see their situation.
The psychologists visits the hoarder's home and make an assessment, know what triggers the hoarding and start from there. They also work with professional organizers to help the hoarder straighten their situation. The good thing about these days era is that, psychologists are available for every situation. Dr. Toni Atkinson is a clinical psychologist that provides his expertise on educational, developmental and cognitive assessment on individuals with difficulty on the said levels. He treats younger and older people with the above mentioned issues.
