Answer this question to the best of your ability:
Are there any historical or societal factors that contribute to this difference in emphasis?
Yes, historical and societal factors may also play a role in the greater emphasis on autism. For example, there has been a significant increase in the prevalence of autism diagnoses in recent years, which could lead to more public awareness and funding for research. Moreover, autism is often viewed as a "mystery" due to its complex and varied symptoms, which may make it more appealing to researchers. In contrast, ADHD has been more widely studied and understood, with research focusing primarily on developing effective treatments for the disorder's symptoms.
