Question: Hello Dr. Faraone, 
  
  Thank you for offering your time.  I hope this question is relevant. 
  
  I was diagnosed privately at 24/25 years old and met the criteria for inattentive type ADHD, however prior to this I was diagnosed with borderline personality disorder. They are now querying autism spectrum disorder alongside my ADHD. 
  
  If possible, my question is - I wanted to know how similar traits are between BPD and ADHD and if there is any correlation when diagnosing at all? Can a person clearly fit BPD criteria and then ADHD/ASD, or perhaps this was an overlook by clinician?
  
  Thank you again.
Answer: &gt;Can a person clearly fit BPD criteria and then ADHD/ASD
  
  It is very common for a person to validly meet criteria for several disorders.  Current research suggests that this is partly due to disorder sharing common genetic and environmental risk factors.
