Frequently Asked Questions

What causes ADHD? Is it really a disorder?
The term “Attention-Deficit/Hyperactivity Disorder (AD/HD)” is often used to include the medical diagnosis of ADHD or ADD (attention deficit without hyperactivity). AD/HD is characterized by developmentally inappropriate inattention and/or possible impulsiveness. In some cases, hyperactivity can be a major factor.
Most research indicates that is caused by a neurobiological disorder that affects 3-5 percent of school age children nationally and approximately 2-4 percent of adults. Those statistics are commonly increasing to about 7.5%, or more, as diagnostic awareness is more prevalent, and more girls and adults become identified. The actual percentage of those affected and diagnosed can vary by location for many reasons including the willingness and ability to identify and treat the symptoms.
Is ADHD over or under-diagnosed or treated incorrectly?
This is a difficult question to answer in a general sense. To have an accurate diagnosis requires the need for a knowledgeable medical or psychological professional, who fully understands the diagnostic criteria of AD/HD, to carefully review the patient’s history in a variety of settings (home, education, social, etc…) with caregivers and educators. In addition, other possible explanations (medical, physical or psychological conditions) should be considered and ruled out as possible explanations for the concerns. In the event a careful diagnosis is not made; or other possible conditions which could show similar symptoms to AD/HD are not ruled out, the patient could be misdiagnosed.
What other resources or websites do you recommend to parents for further information?
