What this Trial Is About
Researchers are studying spatial neglect, a common cognitive disorder after stroke that causes difficulty in noticing stimuli on one side, often the left. This research aims to define standard test results for spatial neglect in healthy adults without neurological diseases, considering factors like age, sex, and education level. Establishing these norms is essential for accurately diagnosing spatial neglect in patients and understanding variations in normal populations. Participants will undergo four standardized paper-and-pencil tests for spatial neglect assessment, including the Apples Cancellation Test for visual neglect, the simplified Comb and Razor Test for personal and motor neglect, a blind line bisection test for tactile neglect, and a dot test for visual exploration. The tests use French-translated instructions, and the study plans to include 210 healthy French-speaking volunteers aged 20 to 89 years, divided into 10-year age groups with equal numbers of men and women. Participants will be assessed once during the study at the neurovascular department. Researchers will collect test scores and analyze them statistically to identify the influence of age, sex, occupational level, hand used, and laterality on test results and completion times. The primary outcome is the average score on the Apples Cancellation Test after 12 months. Secondary outcomes include average scores on the other tests at inclusion. This helps set reference standards to interpret spatial neglect assessments in patients.
