ADHD Testing

Overview of ADHD testing

Attention Deficit Disorder or Attention Deficit Hyperactivity Disorder is a clinical diagnosis that is diagnosed accurately by a psychiatrist through an interview. However there are several objective based tests that complement the clinical interview and aid in establishing a diagnosis. These tests include CPT3 Conners Test, TOVA-9, Creyos Cognitive Testing, and the QbTest.

ADHD testing in children

Furthermore, subjective based questionnaires which can aid clinicians in making a diagnosis of ADHD are available. Certainly, these include the Vanderbilt questionnaire for children, which is administered to parents and teachers for children. Meanwhile, for adults, another commonly administered questionnaire is the Adult ADHD Self Report Scale (ASRS).

ADHD testing in adults

However, the diagnosis of ADHD in adults is more complex as ADHD is conceptualized as a childhood condition. However, it is possible that due to cultural factors or lack of awareness, the diagnosis can be missed in children who persist with ADHD symptoms into their adulthood

Conners CPT3 Test

Mostly, ADHD testing via Conners CPT3 or TOVA-9, are administered via a computer-based program and entail the rapid presentation of a series of visual or auditory stimuli (eg, numbers, letters, number/letter sequences or geometric figures) over a set timeframe. Typically,  the TOVA-9 Test requires an individual to watch and press a button whenever a certain shape appears.

QbCheck and QbTest

  • QbTest is FDA approved, widely available objective test that measures core ADHD symptoms: activity, attention and impulsivity. Often, a typical test lasts between 15 to 20 minutes.
  • The clinical evidence consists of 40 different studies, of which the majority are peer reviewed independent publications. The subject follows simple instructions to hit the space bar on a keyboard after receiving prompts. The computer then measures movement, reaction time, errors (omission or commission). The performance is then compared against normative performance.
  • The test results are instantly analyzed and a report that compares a patient’s results with a group of people of the same age and gender who do not have ADHD is generated.
  • Equipment includes a headband, motion-tracking camera, and stand. Access to the QbTest reporting tool (QAT), allowing you to view test reports and do re-test comparisons. 

Neuropsychological Testing

Neuropsychological testing is available in person with a neuropsychologist who may conduct a series of tests. Testing is an intensive battery of tests typically through a psychologist or neuropsychologist. This testing can sometimes take multiple days to complete but typically provides very extensive reporting. Often times, insurance companies do not cover neuropsychological testing or many practitioners do not take insurance to adminster this type of testing. The cost of neuropsychological testing can sometimes be several thousand dollars.

 Cambridge Neuropsychological Test Automated Battery (CANTAB)

The CANTAB has modules for several brain functions and processes including psychomotor and motor speed, reasoning and planning abilities, memory and attention, and frontal, temporal and hippocampal dysfunctions. Thus, it allows assessment of neuro-cognitive dysfunctions associated with neurologic disorders, medication side effects, and neuro-cognitive syndromes. Finally, the mean time for the battery administration is 40 minutes.
