Standardizing tests that detect spatial neglect.
Standardization of Spatial Neglect Assessment Tests in a Francophone Population
This project will test neuropsychological tasks in healthy French-speaking adults to create reference scores that help clinicians decide when a person has spatial neglect.

What this trial studies
The study will enroll 210 healthy volunteers aged 20–89 at the neurovascular department of Raymond-Poincaré Hospital to generate normative data for visual, tactile, personal and motor neglect tests. Investigators will administer French-language versions of target cancellation tasks (including an Apples-style test), tactile midpoint and exploration tasks, and a simplified Comb and Razor Test under standardized conditions. Exclusion criteria remove individuals with prior central neurological disease or significant uncorrected visual impairment to ensure norms reflect non-pathological variation by age, sex, handedness and education. The resulting reference values will be used to define pathological thresholds for diagnosing different types of spatial neglect in clinical populations.
Who should consider this trial
Good fit: Healthy French-speaking adults aged 20–89 with no history of central neurological disease, sufficient corrected near vision, and capacity to consent are the intended participants.
Not a fit: People with prior stroke, transient ischemic attack, multiple sclerosis, epilepsy, significant uncorrected visual impairment, or abnormal neurological exams are excluded and would not benefit from participating in the norming effort.
Why it matters
Potential benefit: If successful, clinicians will have validated French reference norms for multiple spatial neglect tests, improving diagnostic accuracy and interpretation of patient results.
How similar studies have performed: Related target-cancellation and tactile neglect tests have produced useful normative and diagnostic data in English-speaking cohorts, but a validated French-language standardization is novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Healthy volunteer attending the neurovascular department of Raymond-Poincaré Hospital 2. Aged between 20 and 89 years 3. Affiliated with a health insurance scheme 4. French-speaking 5. Has freely and knowingly expressed their non-opposition Exclusion Criteria: 1. Known history of central neurological disease: stroke (ischemic or hemorrhagic), transient ischemic attack, encephalitis, multiple sclerosis, or epilepsy. 2. Medical interview suggesting past central nervous system involvement: history of episodes such as sensorimotor deficits, dysarthria, aphasia, blurred or double vision, or positive symptoms such as visual or sensory hallucinations (e.g., paresthesias). 3. Significant visual impairment - as judged by the examiner - in near vision despite correction, or monocular blindness. Specifically, inability to distinguish the targets with gaps in the example (pre-test) of the Apples Cancellation Test. 4. Abnormal neurological examination: 1. National Institutes of Health Stroke Scale (NIHSS) score \> 0 2. Pyramidal reflex syndrome (hyperactive deep tendon reflexes with extended reflexogenic zones and spread). 5. Use of substances (alcohol or drugs) within 24 hours prior to the assessment. 6. Presence of cognitive or psychiatric disorders, assessed during the inclusion interview and neurological examination, at the examiner's discretion. 7. Language barrier or aphasia, assessed during the inclusion interview and neurological examination, at the examiner's discretion. 8. Participant under legal protection (guardianship, curatorship, or legal safeguard).
