Some common symptoms of attention deficit hyperactivity disorder in adults include restlessness, disorganization, frequent mood swings, impulsiveness and problems with completing tasks, according to the Mayo Clinic. ADHD sufferers can also have trouble concentrating, a low tolerance for frustration, a quick temper and issues coping with stressful situations.
Adults can be diagnosed with any of the following subtypes of attention deficit hyperactivity disorder: impulsiveness, hyperactivity and inattention, according to Healthline. Attention deficit disorder is an outdated term that used to refer to the condition without hyperactivity. Around 5 percent of children have ADHD, and roughly half of them will carry those symptoms as they grow up. While the most common symptom of ADHD is a lack of focus, many sufferers also experience the flip side of the condition, which is hyperfocus.
Potential warning signs of adult ADHD include reckless driving, poor listening skills, persistent tardiness, issues meeting obligations and extreme procrastination, notes WebMD. Those who have trouble maintaining focus with work, controlling emotions or organizing their responsibilities may be suffering from ADHD as well.
Some adults with ADHD may be described as tense or edgy, according to WebMD. The hyperactivity that accompanies ADHD causes restlessness and makes it difficult for the person to relax, even when responsibilities are absent. In some cases, adults with ADHD may have prioritizing issues and put more effort into insignificant tasks instead of big obligations or work deadlines.
Other symptoms in adults with ADHD include being hypercritical, unmotivated and prone to repeated cases of impulse buying, according to Healthline. Professionals with ADHD can also share common habits, such as changing employers often and having few significant achievements.
