ADHD is a common brain disorder that affects about 5 percent of children, according to the American Psychiatric Association. But, some studies show this number may be higher.

The condition is usually diagnosed at a young age and the symptoms often follow a person into adulthood. In the video below, Health magazine outlines five things you may not know about adult attention deficit hyperactivity disorder.

1. Symptoms Start In Childhood

Although it’s called adult ADHD, symptoms usually begin before 12 years old, and sometimes are noticeable as early as 3 years of age, according to Mayo Clinic. The disorder is categorized into three types: inattentive, hyperactive impulsive, or combination. Children who are predominantly inattentive may be easily distracted, forgetful, and disorganized. Kids who are predominantly hyperactive or impulsive may be in constant motion, talk excessively, and interrupt others. In the United States, it’s most common for children to be diagnosed with the combination subtype, which means they exhibit a mix or inattentive and hyperactive-impulsive symptoms.

2. Many Adults Aren’t Aware They Have It

Many adults may not be aware they have the neurodegenerative disorder, but they are well-aware that their daily tasks are challenging for them.

3. Symptoms May Decrease With Age

Some children’s ADHD symptoms may lessen with age; however, for many children, their symptoms follow them into adulthood, which makes it hard for them to function day to day.

4. Symptoms Look Different In Adults Than Children

Both children and adults with ADHD exhibit varying degrees of symptoms, from mild to severe. However, the symptoms in children may not be the same ones seen in adults. Some of the common symptoms among adults include poor time management skills, trouble multitasking, poor planning, low frustration tolerance, frequent mood swings, and trouble coping with stress.

5. Medications For Children Tend To Work For Adults

Although medications help ease ADHD symptoms, they are not a cure for the disorder. Psychological counseling (psychotherapy) is also usually suggested for adults with ADHD. Therapy can help to develop more effective problem-solving skills, improve self-esteem, and learn ways to communicate better with family, co-workers, and friends.
