A person with ADHD will not necessarily develop another mental health disorder. It will depend on the symptoms they experience, the impact on their daily life, and the family support they receive, which will determine the course of their illness. We know that people with ADHD have a higher risk of dropping out of school prematurely, achieving educational levels below their potential, and being more prone to accidents, unwanted pregnancies, substance abuse, or leaving their jobs. However, with appropriate treatment, a person can avoid all these complications.
