The best way to deal with an adult with ADHD is to provide understanding, open communication, and structure on a daily basis. It is important to be patient and consistent with those who have ADHD, provide daily reminders, and break down tasks into smaller steps. Sticking to a routine can help keep them organized and on track with daily tasks. Additionally, it can be beneficial to involve them in problem-solving when working towards a goal. Encouraging methods of self-care are also important for those with ADHD.
