This project aims at validating a new neuropsychological test to measure voluntary and involuntary attention for clinical use to diagnose attentional deficits.
This project proposes:
- a test-retest procedure in healthy subjects aged from 6 to 90 year-old;
- testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment;
- testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment.
Condition or disease | Intervention/treatment | Phase |

Attention Deficit Hyperactivity Disorder | Other: experience 1 : Competitive attention test in healthy participants Other: experience 2 : Competitive attention test in patients with ADHD with no treatment Other: experience 3 :Competitive attention test in patients with ADHD with psychostimulant treatment | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 180 participants |

Arm | Intervention/treatment |
---|---|
Experimental: Healthy participants aged from 6 to 90 year-old |
Other: experience 1 : Competitive attention test in healthy participants
Comparison of behavioral measures (reaction times and percentage of correct responses) obtained twice with the CAT test in healthy participants (2 to 6 weeks apart). |
Experimental: patients with ADHD with no treatment
patients with ADHD aged from 6 to 90 year-old with no treatment
|
Other: experience 2 : Competitive attention test in patients with ADHD with no treatment
Behavioral (reaction times and percentage of correct responses) and Electroencephalography (EEG) measures obtained with the CAT test in patients with ADHD with no treatment. |
Experimental: patients with ADHD with treatment
patients with ADHD aged from 6 to 90 year-old with psychostimulant treatment (Methylphenidate)
|
Other: experience 2 : Competitive attention test in patients with ADHD with no treatment
Behavioral (reaction times and percentage of correct responses) and Electroencephalography (EEG) measures obtained with the CAT test in patients with ADHD with no treatment. Other: experience 3 :Competitive attention test in patients with ADHD with psychostimulant treatment Behavioral (reaction times and percentage of correct responses) and EEG measures obtained with the CAT test in patients with ADHD before and after psychostimulant treatment. |
- Reaction times in healthy subjects and patients with ADHD. [ Time Frame: 6 weeks ]Reaction times in milliseconds obtained with the CAT test in healthy participants and in patients with ADHD.
- Percentage of correct responses in healthy subjects and patients with ADHD. [ Time Frame: 6 weeks ]Percentage of correct responses obtained with the CAT test in healthy participants and in patients with ADHD.
