Attention Deficit Hyperactivity Disorder
(ADHD) ADHD is the most common childhood neuro-
behavioural disorder defined by symptoms ofdevelopmentally inappropriate inattention, impulsivityand hyperactivity (Polanczyk 2007).
Up to 60% of children with ADHD will continue to havesignificant ADHD-related symptoms persistinginto adulthood (Gentile et al. 2006).
Twin, family and adoption studies have suggested thatthere is a strong genetic contribution to ADHD, with amean heritability estimate of 76% (Faraone 2005) .
Control vs. ADHD - fMRI
2-3 years of delay incortical maturationbetween ADHD andhealthy controls.
First developed in the early 60s.
Computerized, objective measurement tool.
Basic go/no-go task.
Serves as an objective decision support tool in the ADHD diagnosis procedure.
CPTsContinuous Performance Test
T.O.V.A Test (Developed in 1966)
Go - No Go Test
Advantages: Popular & traditional
market. Allows Test-Retest
evaluation.
Disadvantages: Visual channel only. OFFLINE system. Peripheral vision. Norms from the 80's
(North American).

d-CPT Test
Next-generation CPT.
Objective tool to evaluate attentive profile in patients Age 7 and above.
Innovative distractor approach challenges attentional and executive systems to improve sensitivity and specificity over legacy CPTs.

Test Simulation
The Four Attentiveness Indices
Attention (A)
The ability to respond correctly and remain focused.
Timing (T)
The ability to respond quickly and accurately.
Example for a perfect timing
Example for a less perfect timing
The Four Attentiveness Indices
Impulsiveness (I)
The tendency to respond hastily, before evaluating the
situation.
Hyperactivity (H)
A difficulty in regulation of motor responses.

Getting startedImportant technical issues
Use wired internet connection only (not cellular or WIFI).
Recommended browser Google Chrome.
Use a keyboard thats wired connected to the computer.
Use external speakers (not screen built in speakers).
Turn off any irrelevant software running in the background (Skype, outlook, etc.).
Make sure all pop-up elements are neutralized.
After test begins- do not touch the mouse.
If using a laptop (not recommended).
Use wire internet connection.
Connect external wired keyboard and mouse.
Summary: MOXO d-CPT Test General Objective measures for key attention parameters. Low overhead, easy deployability. Flexible business model. International partnering opportunities.
ClinicalDecision Support Beyond CPT. Significant unmet need .
Rapid adoption in the field. Decision support for challenging diagnoses.
DSM-V adult criteria have added additional uncertainty. Multiple reports, including developmental age and longitudinal tracking.
