ADHD Testing


ADHD Testing

ADHD testing Overview

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

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

Conners CPT3 Test

Conners CPT3 or TOVA-9, which are administered through 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. 

TOVA-9 Test here the person taking the test has to watch and press a button whenever a certain shape appears. 

QbCheck and QbTest

  • QbTest is an FDA cleared, widely used objective test that measures core ADHD symptoms: activity, attention and impulsivity.
  • A typical test lasts between 15 to 20 minutes.
  • The test results are instantly analyzed and presented in a report that compares a patient’s results with a group of people of the same age and gender who do not have ADHD.
  •  Equipment including 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. 
  • The clinical documentation 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. 

Neuropsychological Testing

Neuropsychological testing is usually performed in person with a neuropsychologist who may administer a serries of tests.

 Cambridge Neuropsychological Test Automated Battery (CANTAB)

The CANTAB has modules for several neurocognitive 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, pharmacologic manipulations, and neuro-cognitive syndromes. The mean time for the battery administration is 40 minutes.
