Klüver–Bucy syndrome may present with compulsive eating, hypersexuality, insertion of inappropriate objects in the mouth (hyperorality), visual agnosia, and docility
As part of an investigation by Heinrich Klüver in the 1930s into the area affected by mescaline, Klüver arranged to have the temporal lobes of a number of rhesus monkeys bilaterally removed by Paul Bucy, a neurosurgeon.
Yeah that's what lead me there. I was reading about the limbic system and thinking man limbic system issues sound a lot like ADHD symptoms. The way I think about it is degrees of decreased function. Like with ADHD the system largely functions, just slightly less than in neurotypical people, and with this it's closer to completely nonfunctional. It's just interesting to see the parallels.
