As per title. I am a sociologist researching mental health and illness. I also have ADHD. Broadly speaking, with greater understanding of conditions such as ADHD, ASD, and others, we have begun to categorize them not as illnesses or defects but rather as naturally occurring variations of the human brain. The problem isn't with the brain per se, but rather that human societies are, broadly speaking, structures around the thought processes of neurotypical persons.
Has anything like neurodivergence been observed in wild animals? Things like, say, members of an animal pack being slow, or easily distracted, or irritable? My intuition is to say yes because some animals have rather complex social organization, which is necessarily based around a "mental norm." But that's just a hunch, so I'm asking here for further sources.
