What kind of doctor treats ADHD?
A psychologist or a psychiatrist (a mental health doctor) can diagnose and treat 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 ADHD?
ADHD is short for attention deficit hyperactivity disorder. It is a problem with focus, activity level, and self-control. It is common for people to show these behaviors some of the time. In ADHD, they are frequent and happen in many settings, like school, home, and work. They get in the way of daily life.
ADHD is one of the most common disorders diagnosed in children. Symptoms begin in childhood and usually continue into the teen years and adulthood.
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.
Some people have mostly one kind. Others have a mix of all three. To be ADHD, the problems must be beyond the normal range for a person's age and development.
Causes and who gets it
It is not clear what causes ADHD. It may be linked to genes and home or social factors. The brains of children with ADHD are different from those of children without ADHD. Brain chemicals are also different.
The CDC lists possible risk factors. They include genes, contact with lead early in life, alcohol or tobacco use during pregnancy, head injuries, and family life. ADHD is diagnosed more often in boys than in girls.
How doctors diagnose it
No test can diagnose ADHD. The diagnosis is based on a pattern of the symptoms above. When a child may have ADHD, parents and teachers are often part of the evaluation.
Most children with ADHD have at least one other mental health or learning problem. It may be a mood, anxiety, or substance use problem.
Treatment
In most cases, ADHD is best treated with a combination of behavior therapy and medication. For kids ages 4 to 5, behavior therapy comes first, before medication.
Stimulants are the most commonly used medicines. They have a calming effect on people with ADHD. Non-stimulant medicines can also help some people. Some ADHD medicines have side effects. If side effects happen, contact your provider right away.
Behavior therapy teaches kids and parents healthy habits and ways to handle hard behaviors. For mild ADHD, behavior therapy alone may be enough. Daily habits help too. Keep a regular schedule, limit distractions, serve a healthy diet, and make sure your child gets enough sleep.
There is little proof that herbs, supplements, or chiropractic care help.
When to see a doctor
Contact your provider if you or your child's teachers suspect ADHD. Also tell the provider about problems at home, school, or with peers, side effects of medicine, and 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
What are the three types of ADHD?
ADHD shows up in three ways. Some people are mostly inattentive. Some are mostly hyperactive and impulsive. Others are combined, with a mix of both.
Is there a test for ADHD?
No test can diagnose ADHD. The diagnosis is based on a pattern of symptoms. Parents and teachers are often part of the evaluation.
Does ADHD last into adulthood?
It often does. Symptoms usually continue into the teen years and adulthood. One third to one half of children with ADHD have symptoms of inattention or hyperactivity-impulsivity as adults.
What is the main treatment for ADHD?
In most cases, ADHD is best treated with a combination of behavior therapy and medication. For preschool-aged children, behavior therapy is recommended first.
