And neither are they symptoms of a specific biological malfunction. We just happen to be highly social animals and if we are continually denied social interaction we'll start to do increasingly stupid things to provoke a reaction. Programs that give those people an outlet for their interaction needs will work wonders for almost all of them. Zero care freedom versus lockup/forced medication is a false dichotomy.
