To some, it may seem like ADHD and introversion are opposites. ADHD is associated with a lot of extroverted behaviors. However, it is important to remember that introversion is about recharging when alone and not around other people. Introverts can be outgoing, while still needing that alone time. In fact, a 2017 study of 117 people with ADHD found that 58.1% of them were introverts. Therefore, it is, indeed, possible to be an introvert and have ADHD.
