The screening and assessment of attention-deficit/hyperactivity disorder (ADHD) is a process that involves multiple steps to determine if a person has ADHD and to determine the appropriate treatment. The process typically involves a combination of psychological testing, physical exams, and input from parents, teachers, and other caregivers.

The first step in the screening and assessment process is a thorough review of the person's medical and family history. This can provide important information about the person's symptoms and any potential risk factors for ADHD.

The next step is a physical exam, which can help rule out other possible causes of the person's symptoms, such as hearing or vision problems. The physical exam may also include laboratory tests to check for conditions that may be associated with ADHD, such as thyroid problems or sleep disorders.

Once medical conditions have been ruled out, the next step is psychological testing. This may include a variety of tests to assess the person's attention, memory, and problem-solving skills. These tests may be administered by a psychologist or other mental health professional.

In addition to psychological testing, input from parents, teachers, and other caregivers can be helpful in the assessment of ADHD. These individuals may be asked to complete questionnaires about the person's behavior and to provide information about how the person functions at home and at school.

After all of the information has been gathered, the healthcare provider will review the results and determine if the person has ADHD. If ADHD is diagnosed, the healthcare provider will work with the person and their family to develop an appropriate treatment plan. This may include medication, therapy, or other interventions.
