It’s not uncommon for individuals with attention deficit hyperactivity disorder (ADHD) to struggle with anxiety, whether it’s several symptoms or a full-blown disorder.
In fact, about 30 to 40 percent of people with ADHD have an anxiety disorder, which includes “obsessive-compulsive disorder, generalized anxiety disorder, phobias, social anxiety and panic disorder,” according to Roberto Olivardia, Ph.D, a clinical psychologist and clinical instructor at Harvard Medical School. The Anxiety Disorders Association of America even estimates the figure to be almost 50 percent.
Here’s why ADHD and anxiety co-occur (occur together), how this affects treatment and several strategies for coping with anxiety.
