The article I linked to about Japanese clutter mentioned the Collyer brothers° who were hoarders who died in their home – one after being trapped by the rubble, the other of starvation.

They were born in the 1880’s and died in 1947. And it got me thinking about how far back certain mental illnesses go.

Some I’m sure are caused or exacerbated by our modern world. But surely some mental illnesses were present in tribes, say, 30,000 years ago. Did any of them get depression, ADHD, hoarding, PTSD, OCD, or eating disorders? Which ones are inherent in our make-up?
