Summary

This study aims to establish normal scores for four paper-and-pencil tests that detect spatial neglect, a common attention problem after stroke. Researchers will test 210 healthy French-speaking adults aged 20 to 89, divided by age and sex. The results will help doctors know what scores are normal versus signs of neglect, improving diagnosis accuracy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to: If successful, this study will provide reliable benchmarks for diagnosing spatial neglect after stroke, leading to better and earlier detection.
What could go wrong: This is an observational study in healthy volunteers, not a treatment trial. The results may not apply to all populations or settings.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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).
