This is pretty much what I was wondering. How many of these classifications (such as autism) cross cultural/linguistic boundaries?
Obviously nitpicking one identifying characteristic (object personification) isn't really valid to dismiss the diagnoses entirely. Perhaps it's a valid diagnostic and Japanese culture is just more accepting of certain autistic personality traits, where American culture would suppress them. Identification of weird/unusual/possibly unhealthy behavior can be hard to separate from cultural norms.
I don’t have any specific examples off hand but HealthyGamer on YT is a psychiatrist with both a western medical degree and traditional training in India. He often compares the two, where they align, etc.
That section wrh similar articles towards te bottom is dangerous. I just went on a 30 minute dive reading abstracts of recent research studies of autistic people and only stopped because I have to get to bed soon. I'll be back for more tomorrow.
