Is ADHD over Diagnosed?

Quick Judgements?

People are prone to make quick judgments. And, when it comes to diagnosing a student with Attention Deficit Hyperactivity Disorder (ADHD), teachers, parents, school administrators, doctors and specialists are not immune to this habit.

It’s easy to spot the symptoms of ADHD:

• fidgeting,
• easily distracted,
• compulsiveness, and
• an inability to focus on multiple tasks.

The problem, though, is that these symptoms often mimic other learning and developmental disorders.

These can be symptoms of something else. The critical debate about over diagnosing ADHD is real. Simply put, more people are being diagnosed with the condition. But are they the right diagnosis? The answer is surprisingly complex. While it appears that ADHD is being over diagnosed, the tools to differentiate between other symptoms are getting better. Still, one diagnosis doesn’t always give a clear picture.

Other Conditions

As a special educator for over 25 years, I’ve had a lot of students go in and out of my classes. In many cases, you can tell that ADHD is a major factor. In others cases, one can tell that a student's disability may deal with something else. But, his IEP doesn’t always address this. In others cases, ADHD may be one of many conditions that hinders their learning ability.

Processing disorders, dyscalculia (math disorder), dyslexia and developmental disorders such as higher forms of autism (i.e. Asperger’s syndrome) share some of the same characteristics as ADHD. By appearance many of these students with one of these disorders mentioned may show signs of inattention, delayed responses, and distraction.

Another reason – and this may sound ironic – is that this is a desirable condition to be diagnosed as having.

One condition in particular, Auditory processing disorder, a condition in which the brain processes auditory messages in a slow or delayed process, shares many of the same symptoms of ADHD. Often, those with this condition have a hard time concentrating on one source of sound and have difficulties filtering out other auditory sources in the classroom. As a result, the student may appear to be “daydreaming” or off task while taking notes from a teacher’s lecture.

Why the Over Diagnosis?

The over diagnoses of ADHD are often honest mistakes. Usually, the conditions are easy to spot and the public knowledge of this condition is much higher as compared to other conditions. In part, this condition has received more media attention than any other learning disorder.

Another reason – and this may sound ironic – is that this is a desirable condition to be diagnosed as having. As well as being easily diagnosed, ADHD can be easily treated. Over the years, medication has been prescribed to treat this condition, in some cases, rendering its symptoms almost non-existent.

Also, on school campuses across the country, the diagnosis of ADHD means that a student doesn’t have to get special education services. Often, the medication will be the only accommodation needed as well as a Section 504 plan to ensure the student is not discriminated against in the classroom.

Section 504 is a civil rights bill that ensures that students with a disability will have reasonable accommodations and equal access to the same education material as their non-disabled peers. This, in part, means that students with ADHD are to be included in the general education population with some accommodations.

Multiple Diagnosis

Still, the diagnosis of ADHD is often the first step, rather than a conclusive one. If the student still struggles in school despite accommodations and medication given to him/her, a new round of assessments is needed. This usually happens more frequently than is often reported. And, often, a learning disability such as auditory processing or dyslexia is discovered to be at the heart of the student’s learning disability.

ADHD does affect many students. In fact, in many cases, the condition can be present with other conditions. This is where the belief that ADHD is being over diagnosed gets murky. There have been several incidents in which a student was diagnosed with Asperger’s syndrome and ADHD.

This condition is serious, and a proper diagnosis of it can help a student, his/her parents and teachers...

This is actually very common. ADHD has been diagnosed with other specific learning disorders such as visual or auditory processing disorders. In some cases, ADHD is, itself, listed as a processing disorder Still, in these cases, ADHD is a secondary, not primary, cause for a learning disorder (To note: ADHD is usually designated as OHI or Other Health Impairment in an IEP).

Still, many so-called cases of ADHD may have turned out to be misdiagnosed. And, it usually takes multiple assessments to come up with a more definitive diagnosis of a learning disability. To date, many cases of ADHD have turned out to be auditory or visual processing disorders – possibly the two most common learning disabilities reported.

Why Does It Matters?

This condition is serious, and a proper diagnosis of it can help a student, his/her parents and teachers, to make academic plans that can address the students’ academic needs. However, this can be done when a thorough assessment can be made rather than settling on what appears to be the obvious.

ADHD is being diagnosed at high numbers. In some cases, it may be the wrong diagnosis or can be part of several conditions that may affect a student’s ability to learn in the classroom. Still, an ADHD diagnosis doesn’t happen over night. It may involve more testing. But, it’s necessary in order to find the right treatment and tactic to help the students be able to access the same curriculum as their nondisabled peers.
