What kind of doctor treats ADD/ADHD?
A psychiatrist (a mental health doctor) or a psychologist can diagnose and treat ADD and ADHD. For children, a pediatrician (a children's doctor) can also do it. 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 ADD/ADHD?
ADD is another name for ADHD. ADHD is short for attention deficit hyperactivity disorder. Doctors today call it ADHD.
ADHD shapes how the brain grows and works. It makes it hard to plan, stay focused, and hold back impulses (the urge to act fast). ADHD is not caused by laziness, poor discipline, or low intelligence. Many people with ADHD lead good lives. They may need help to manage symptoms.
The name has changed over time. Doctors once called it minimal brain dysfunction. In the 1970s they called it hyperkinetic reaction of childhood. The name ADHD came in the 1980s.
Symptoms
ADHD symptoms fall into three groups:
- Inattention (trouble focusing): careless mistakes, weak focus, lost items, and poor organization.
- Hyperactivity (too much movement): fidgeting, leaving the seat, and often being on the go.
- Impulsivity (acting without thought): blurting out answers and trouble waiting for a turn.
Symptoms differ from person to person. They can change with age. ADHD is first found in childhood and often lasts into adulthood.
Causes and who gets it
No one knows the exact cause. Studies point to a few factors:
- Genes. ADHD tends to run in families.
- Environment. More cases are found after contact with lead or dirty air before birth or in early life.
- Brain form and work. The brain may differ in shape or in how it works.
Alcohol or tobacco use during pregnancy may add risk. So can head injuries and family life. In childhood, boys get the diagnosis more often than girls. In girls, signs are often more subtle.
How doctors diagnose it
There is no single test for ADHD. The doctor looks at symptoms, history, and behavior. A psychologist, a psychiatrist, or a pediatrician can make the diagnosis.
The doctor asks when signs started and how bad they are. The doctor also checks for other causes. Other problems can look like ADHD.
Treatment
In most cases, ADHD is best treated with behavior therapy and medication together. For kids ages 4 to 5, parent training is tried first, before medication.
Medication can help focus and attention. Doctors prescribe stimulants most often. Non-stimulant options exist. Medication can cause side effects, and finding the right one can take time. If side effects happen, call your doctor right away.
Behavior therapy teaches skills for time, order, and problem-solving. For mild ADHD, behavior therapy alone may be enough. Good habits help as well, like exercise, balanced meals, and enough sleep.
When to see a doctor
Call a doctor if teachers or you suspect ADHD. Tell the doctor about problems at home, school, or with friends, and about signs of depression. 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. This kind of doctor can do a first check, watch symptoms, manage general health, and refer you to mental health care.
Common questions

Does ADHD last into adulthood?
It often does. One third to one half of children with ADHD have these symptoms as adults.
What is the main treatment for ADHD?
In most cases, ADHD is best treated with behavior therapy and medication together. For young kids, behavior therapy is tried first.
Is ADHD caused by laziness or bad parenting?
No. ADHD is not caused by laziness or a lack of discipline. Genes, environment, and brain differences play a role.
