It used to be that only children received a diagnosis for ADHD. Today, parents have their kids diagnosed, and frequently realize that they themselves have lived their life with undiagnosed ADHD. Since ADHD is highly genetic, we now see grandparents realizing that they too have experienced unexplained frustration and anxiety.
Not only does ADHD present challenges for those that have been diagnosed, but frequently for their loved ones. For those with ADHD, close relationships often present confusion and anger. Even if you, yourself, don't have ADHD; it can be difficult to be in close relationship to a loved one that does.
Because of the complexities of coping with this condition, I work with people that have ADD/ADHD in addition to people who love people with ADD/ADHD! In all of these situations, a baseline of education and some well targeted strategies are crucial.
