Added Value of the Oculomotor and Cognitive Examination in the Management of Patients With ADHD

Type of study and experimental plan:

This is an interventional study designed to evaluate routine care. Number of Necessary Subjects Participants will be stratified by age to control the effect of age. The age groups to be analyzed are: 7-9 vs 10-12 vs. 13-18 versus 19-29 vs 30-40 and 41-50, each with at least 15 participants. total of 90 participants.

• Study population The patients included in this study are followed in the general psychiatric department of the Rouffach hospital center for attention deficit disorder with or without hyperactivity (ADHD). The study focuses on ADHD patients aged 7 to 50 years, undergoing an oculomotor and cognitive examination before the initiation of psychostimulant therapy with methylphenidate (MPH) (baseline, V0); two weeks later (V1) following a single low dose administration of MPH (10 mg orally given at 8 AM) ; and at 6-month follow-up (V2) when patients are medicated with adequate dose of MPH.
• Clinical assessments All subjects are evaluated directly by psychiatrists and neuropsychologists who are experts in the field of ADHD and are experienced in the use of standardized or semi-standardized clinical instruments. Clinical investigation allows extensive and standardized evaluation of patients.

1. Categorical standardized assessment of ADHD symptoms Diagnostic and Statistical Manual (DSM-IV-TR) ADHD Criteria: Subtype: Combined, Inattentive, Hyperactive-Impulsive.

• In children-adolescents: CONNERS Evaluation Scale for Teachers and Parents: Hetero-Questionnaire for Assessing Behavioral Disorders in ADHD. ADHD Questionnaire: self-assessment questionnaire for children and adolescents with attention difficulties, agitation and behavioral problems allowing the quantification of ADHD symptoms. ADHD Questionnaire: Hetero-evaluation questionnaire for children and adolescents with attention difficulties, agitation and behavioral problems allowing the quantification of ADHD symptoms. This questionnaire is completed by one of the parents.
• In adults: Adult Self Reporting Scale (ASRS 1.1): self-assessment grid to assess current adult ADHD disorders. Diagnostic Interview for ADHD in adults (DIVA 2.0): semi-structured interview corresponding to the DSM-IV criteria, according to which the diagnosis of ADHD in adults requires the demonstration of symptoms of ADHD both in childhood and at age adult. This scale is composed of 3 parts that apply each to childhood and adulthood: inattention criteria, hyperactivity-impulsivity criteria, age of onset and impaired functioning due to symptoms. Wender Utah Rating Scale (WURS-25): a self-report scale that allows retrospective assessment of the presence of ADHD registry disorders in childhood. World Health Organization Disability Assessment Schedule (WHODAS 2.0): Self-Assessment Scale, to measure pathology-induced disability in daily living during the last 30 days.

1. Standardized neurocognitive assessment

• Intellectual level The intellectual level of the patients is assessed using the Wechsler scales: Wechsler Preschool and Primary Scale of Intelligence (WIPPSI) and Wechsler Intelligence Scale for Children (WISC-IV) according to the age of the subject. The variety of tests proposed by the Wechsler Ladders allows to appreciate the level of cognitive development of the child and adolescents. Adults benefit from Adaptation French National Adult Reading Scale (fNART) which aims to estimate the intellectual pre-morbid level. It consists of a series of 40 words of the French language. The patient is asked to read each word aloud whether or not they know the word. It is therefore necessary to deduce the pronunciation of the word in question.
• Computerized neurocognitive tests o In children up to 10 years KITAP computerized battery: 6 tests of this battery have been selected and are administered in the following order:
• alert
• divided attention
• flexibility
• go no go
• distractibility
• sustained attention o In children from 11 years old/teenagers/adults Computer Battery TAP 2.2: 8 tests of this battery have been selected and are administered in the following order:
• phasic attention
• divided attention
• flexibility
• incompatibility
• go no go
• visual scan
• working memory
• sustained attention The total pass of these tests lasts approximately 45 minutes to which are added 5 minutes of explanation and test (s) for each task (5 x 8). Total duration of the TAP battery run: approximately 1h25.
• Other neurocognitive tests
• In children:
• Memory test
• 15 words of Rey
• Memory test - figures
• Dam tests

1. Standardized assessment of psychiatric comorbidities other than ADHD

• In children-adolescents: Social Communication Questionnaire S.C.Q - Social Communication Questionnaire): A tool for identifying the manifestations of Autonomic Spectrum Disorders in three main functional areas: social relations, communication and restricted, stereotyped and repetitive behaviors. Hetero-quiz for parents or a person who knows the child well. C.A.S.T The Childhood Asperger Syndrome Test: hetero-questionnaire to assess the manifestations of Asperger syndrome.
• In adults: Semi-structured psychiatric interview. Questionnaire Mood Disorder Questionnaire (MDQ): self-questionnaire "mood disorders" allowing screening for bipolar disorders

1. Standardized evaluation of oculomotor behavior Visually guided horizontal and vertical saccade tests: A fixation point is shown in the center of the screen, after a time interval of 200 ms, the center point disappears and a new point appears on the right or left at 20 ° from the initial position. The eyes must move on the new target. Thirty horizontal and 30 vertical saccades are presented Voluntary horizontal saccadic tests: The parameters are identical to those exposed in visually guided saccadic tests except that the central point does not disappear when the second point appears on the right or on the left (top or bottom) at 20 ° from the central point. Thirty horizontal saccades are presented. Anti-saccadic tests: A fixation point is presented in the center of the screen, after an interval of 200ms, the central point disappears and a new point appears on the right or on the left (top or bottom) at 20 ° from the initial position. The eyes must be pointing away from the point. Thirty horizontal saccades are presented. All oculomotor tests last 1 minute. Horizontal and vertical chase tests: A target moves on the screen for about 50 seconds, the eyes must follow the target. The speed of the target varies from 5 ° Reading and Visual Search Tests: A text of 4 lines is presented on the computer screen. The participants must read it in a low voice, the movements of the eyes are recorded while they perform the task. In the visual search test, the same text is presented but all vowels are replaced by consonants. Participants must count in low voices the number of 'r' present in the text.
2. Other parameters collected Sociodemographic data, personal and family psychiatric and somatic antecedents as well as previous and current treatments are collected.
