The restlessness typical of attention deficit hyperactivity disorder makes it difficult to stop moving and shut off from life. This can cause frustration and other symptoms that lead to anxiety.
Anxiety is an incredibly common symptom of ADHD in adults – one that can trigger illness and other unpleasant or bothersome symptoms. It often accompanies fidgeting and the inability to sit still.
Fatigue, which can occur for a variety of reasons with attention deficit hyperactivity disorder and exacerbate attention difficulties, is an ongoing problem for a large percentage of adults with ADHD.
The tiredness may stem from hyperactivity, insomnia, or the continuous effort required by men and women with the mental disorder to focus. It can also be one of the side effects of ADHD medications.
Adults with attention deficit hyperactivity disorder are more likely to experience substance abuse problems than people who don’t have ADHD. This may involve the use of alcohol, drugs, or tobacco.
Why adults with ADHD are more likely to abuse substances isn’t clear, but researchers believe that men and women with the disorder misuse substances to relieve troubling ADHD symptoms.
