Treatment of adhd for children, adolescents or adults is based on a multimodal treatment approach. The most effective therapy is a combination of psychopharmacotherapy (usually psychostimulant medication) and psychotherapy.
You should learn to adapt to the special impairments of adhd (executive dysfunction with problems of self-organization, low frustration tolerance, affective instability) and try to develop good coping skills. One way to handle these problems would be a coach and / or a cognitive-behavioral therapy with self-management skills.
It is important to get sufficient information about the everyday symptoms of this syndrome, and to learn to adapt to the benefits and problems due to the deficits of executive functions. I would recommend keeping symptom diary to monitor typical problems of attention, distractibility or organization skills. With a psychotherapist or coach you can learn to develop appropriate ways to handle these problems and focus on your interests and strengths to develop personal resources.
