Question: Thanks for taking the time to do this! 
  
  Could untreated ADHD lead to body-focus repetitive disorders (e.g. trichotillomania, dermatillomania)? 
  
  A lot of the times, high achieving people with ADHD get misdiagnosed. Is there any recent research on identifying ADHD from data (i.e. fMRI), in a way that helps distinguish the condition from other common comorbidities like anxiety/depression (particularly in atypical ADHD cases)?

  I don't know the answer to your first question.  As for #2, the only diagnostic tool for ADHD is a licensed clinician who interviews the patient about their symptoms and impairments. Rating scales about symptoms and impairments can be helpful but don't replace an interview. In the World Federation of ADHD International Consensus Statement on ADHD (https://bit.ly/3xCr9NE), we concluded that ADHD can only be diagnosed by a licensed clinician who interviews the parent or caregiver and/or patient to document criteria for the disorder. It cannot be diagnosed by rating scales alone, neuropsychological tests, or methods for imaging the brain.  Neuropsychological testing can be very useful for other purposes but not for diagnosing ADHD.
