In July 2017, we launched the expanded BGaze diagnostic report 2.0, which adds to the core BGaze cognitive vergence biomarker a highly graphical representation of quantified CPT data as well as specific other parameters that have been found to relate to an ADHD diagnosis. The report has been optimized in close cooperation with leading clinicians specialized in ADHD diagnostics.  

CPT scores are commonly used to support the clinical ADHD diagnosis. Our BGaze CPT is a child friendly version of a scientific paradigm (Posner task) to study orienting attention, and takes about 10 minutes to complete. The task is to help the frog to catch her tadpoles without looking at them and to ignore fishes (see figure 1). We provide several relevant outcomes of our CPT (hits, misses, correct rejections, false responses, reaction times and variability herein) in our report providing additional support to ADHD diagnosis.

Besides behavioural responses, the results of oculomotor behaviour is incorporated in the report. In line with previous scientific findings (see “Saccadic eye movement applications for opsychiatric disorders”) our validation study demonstrate that saccadic (fast) eye movements bear relevant information for ADHD diagnosis. Our report therefore contains biomarker, oculomotor, and behavioural results supporting a global ADHD assessment of the patient.

The report has been designed in close dialogue with experienced psychiatry clinicians to visualize the outcomes so they can be understood and interpreted in an intuitive way. Below you see some images of the BGaze report.
