I think it's becoming clear that hoarding is a form of mental illness rather than the "simple" issue of a lack of concern for one's family. Not only that but the recidivism rate seems to be approaching 100%. This is a a reality TV producer's fantasy-- an endless supply of new episodes and followups.For me, my greatest sympathies are held for the families of the hoarders. The hoarders themselves tend to be selfish, self-centred people who don't seem to care about the feelings of those around them. It's gut wrenching to see the impact that their actions have on their extended family, yet the hoarder seems to think that it is them who deserves all the sympathy.
Personally I don't think it is ok for a child not to be able to eat at a home cooked meal at the dining room table because mum chooses to have both the kitchen and dining room inaccessible for the usual functions. It is a form of child abuse. The stress on the kids face is so obvious.
One of the few things that changes hoarder behavior-- at least in the short term-- is being reported to Child Protective Services or other zoning/habitation authorities.
