Adult ADHD is best diagnosed by a psychologist, psychiatrist, or neurologist. Only a master's-level therapist should be used for the first screening. Adults with ADHD can only be prescribed medication by a psychiatrist, neurologist, or family physician. All psychiatrists are not the same, so make sure you see someone who specializes in adult mental health. Attention deficit hyperactivity disorder (ADHD) is a brain disorder that causes people to have trouble focusing their attention and controlling their behavior, especially when they're young. Adult ADHD doesn't just go away as people get older—it remains present throughout life. Symptoms of adult ADHD include: difficulty concentrating, paying attention, working on one task for an extended period of time, finding it difficult to stop talking about something that interests you, being prone to making careless mistakes, acting without thinking through consequences. These are all normal symptoms of adulthood and do not indicate a problem with sexual development. People with adult ADHD may also experience anxiety, depression, obsessive compulsive disorder (OCD), bipolar disorder, or substance abuse. A mental health professional can help you understand these related conditions and develop strategies to manage them. It is important to receive proper treatment for any other issues that may be causing or contributing to your adult ADHD symptoms. Psychiatric medications are often necessary to treat ADHD.
