Can a test for ADHD at the age of 15?

Yes. Attention Deficit Hyperactivity Disorder (ADHD) can be diagnosed in children and adolescents at any age.

The diagnosis of ADHD is based on the following criteria:

* Symptoms that have been present for at least six months and are not better explained by another mental health condition.

* Symptoms that are impairing functioning in at least two settings (such as school, home, or social activities).

* The symptoms are not primarily due to another medical condition (such as a thyroid disorder) or substance use.

To diagnose ADHD, a mental health professional will conduct a comprehensive evaluation that may include:

* A clinical interview with the child and parent(s).

* A review of the child's medical and educational records.

* Standardized rating scales to assess ADHD symptoms.

* Cognitive testing.

* Physical examination.

If the evaluation indicates that the child meets the criteria for ADHD, the mental health professional will develop a treatment plan. This plan may include medication, behavioral therapy, and/or educational interventions.
