ADHD symptoms in kids can be difficult to recognize, especially in preschoolers. Here’s how you can tell if your preschooler has ADHD

ADHD is one of the most common neurodevelopmental disorders affecting children, often diagnosed in school-aged children over 6 years old. However, it can also be diagnosed in children as young as 3.

Of course, it’s normal for preschoolers to be inattentive or hyperactive even on their best days. So how can you tell the difference between standard preschooler behavior and ADHD?

What are treatment options for preschoolers with ADHD?

Since the line between common preschooler developmental changes and symptoms of ADHD is blurred, this poses many diagnostic challenges. Although it’s unusual for children to be formally diagnosed with ADHD before elementary school, a growing number of health professionals recognize the benefits of early diagnosis and treatment. 

According to the American Psychological Association and the American Academy of Child and Adolescent Psychiatry, children with ADHD should be treated according to the severity of their symptoms.

Environmental changes

For children who play well with others and have healthy self-esteem, small changes in their environment may help with their ADHD symptoms. Environmental changes may include:

  • Smaller classroom
  • Less stimulation
  • Structure and routine

ADHD behavior therapy

There is increasing evidence that treating ADHD symptoms in preschoolers can be extremely effective if parents are involved in their child’s therapy. Examples of therapy may include:

  • Behavior therapy
  • Parenting skills training
  • Social skills training


Methylphenidate is the most commonly prescribed medication to treat children diagnosed with ADHD, but it is not approved by the U. S. Food and Drug Administration (FDA) for use in children under the age of 6. 

Children ages 4 and older may be prescribed low-dose ADHD medications. It’s important to your doctor about your preschooler to see what they recommend.

Combination therapy

Studies and research show that symptoms of ADHD in preschoolers may improve with combination therapy, which combines behavior therapy with medications.
