There are many reasons to obtain a formal diagnosis of ADHD. However, it’s not always necessary.
A diagnosis of ADHD means that some of the ADHD traits that a person has are significant enough to have a negative impact on their life. It is certainly possible sometimes to get help with creating structures or finding just the right niche that allows a person with ADHD to live in the area of their strengths and not have their ADHD be a significant problem.
There are three main reasons for getting an official ADHD diagnosis. The first and probably most important is that a person just wants to know definitively what has been causing the challenges that they’ve had throughout their life in this area.
Another reason is that a person might want to try and ADHD medication as part of the treatment plan.
A third reason, is that a person, child or adult, may need an accommodation in school work to help them be as as successful as possible in their chosen endeavor.
70% – 80% of my personal clients have an official diagnosis of ADHD.
