Technically the answer to this question is no. ADHD is usually present when an individual is seven years of age or younger. However, due to strict and organized parenting that brought about effective coping mechanisms, ADHD may not have become apparent until later in life.
If this is the case, ADHD might possibly be resolved by developing more mature coping mechanisms, and not necessarily behavioral drugs. Generally, if there were successful coping mechanisms as a child, there should be effective mechanisms that can be used as an adult that can be discovered through counseling and determination.
