Medically reviewed by Achuta Uppu, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Attention Deficit Disorder (ADD)?
A pediatrician, a doctor for children, often checks first. Adults may start with a primary care doctor. Some people see a psychiatrist, a doctor for mental health. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Attention Deficit Disorder (ADD)?
ADD is an older name for attention-deficit/hyperactivity disorder (ADHD), a condition that affects how the brain grows and works. One form is mostly inattentive. In that form, the main problem is trouble focusing, following instructions, and finishing tasks. ADHD involves three kinds of behavior. Trouble paying attention is called inattention. Acting without thinking is called impulsivity. Being overly active is called hyperactivity. Some people have mostly inattentive symptoms. Some have mostly hyperactive and impulsive symptoms. Others have a mix. ADHD affects about 5 percent of children and 3 percent of adults worldwide. In most people, it lasts into adulthood. In about one third, the signs go away by adulthood.
Symptoms
The signs depend on which form a person has. Inattention may look like this:
- Missing details or making careless mistakes in schoolwork or work.
- Trouble staying focused on tasks or play.
- Not seeming to listen when spoken to directly.
- Not following through on instructions. Leaving tasks unfinished.
- Trouble organizing tasks and managing time.
Hyperactivity and impulsivity may look like this:
- Fidgeting or squirming while seated.
- Talking much more than is normal.
- Blurting out answers before questions are finished.
- Trouble waiting their turn. Interrupting others.
For these behaviors to count as ADHD, they must be more than what is normal for a person's age. They must last at least 6 months. They must show up in two or more settings, such as home and school. And they must clearly get in the way of school, work, or social life.
Causes and who gets it
The exact cause of ADHD is unknown. It likely comes from a mix of genes and environment. Changes in dozens of genes have been linked to ADHD. These gene changes combine with things around a person. These may include problems during pregnancy or delivery and contact with lead. People with ADHD often have low dopamine, a brain chemical that helps with attention and motivation. ADHD runs in families. The risk is about nine times higher for close family members of someone with the condition. It is diagnosed more often in boys than in girls.
How doctors diagnose it
There is no single test for ADHD. Diagnosis starts with a physical exam, including vision and hearing tests. These rule out other problems with similar symptoms, such as anxiety, depression, sleep problems, and some learning disabilities. The provider takes a full medical and family history. They use checklists and rating scales. Symptoms must have started before age 12. Children up to age 16 need at least 6 ongoing symptoms. People 17 and older need at least 5.
Treatment
There is no cure for ADHD, but treatment may help reduce symptoms and improve functioning. ADHD is commonly treated with medicines, talk therapy, parent training, or a mix of these. In addition to medication, some children with ADHD receive behavioral therapy to help manage symptoms and provide added coping skills. The FDA has approved two types of medicines, stimulants and non-stimulants. Despite their name, stimulants, which contain forms of methylphenidate and amphetamine, have a calming effect on hyperactive children with ADHD. They are thought to raise dopamine in the brain. The FDA has also approved non-stimulant medicines. These include atomoxetine, guanfacine, clonidine, and viloxazine. Good treatment plans will include close monitoring, follow-ups, and making changes, if needed, along the way.
When to see a doctor
If you suspect your child might have ADHD, see your pediatrician or health care professional. In studies, untreated ADHD was linked to more emergency room visits and self-inflicted injuries. If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can check symptoms and refer you to a mental health specialist. They can also check on treatment over time.
Common questions
Is ADD different from ADHD?
ADD is an older name, not a separate condition. Doctors now use the term ADHD for all forms.
Can ADD be cured?
No, there is no cure, but treatments such as medicine and talk therapy may help reduce symptoms and improve functioning. In about one third of people, symptoms go away by adulthood.
Do children outgrow it?
Some do, but most do not. In most people, ADHD lasts into adulthood. But in about one third, the signs and symptoms go away by adulthood.
Do diet or supplements help?
Healthy eating and regular exercise may help manage symptoms.
What should I do first?
Talk with your doctor if you or your child's teachers suspect ADHD. Have vision, hearing, and anything else that might cause inattention checked. A doctor might diagnose ADHD or refer you to a mental health specialist for evaluation.
