Cog-First was developed as a self-administered, tablet-based cognitive screening tool designed to evaluate executive function, memory, and attention in approximately 20 minutes, starting from the acute phase after brain injury.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>Aim<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To establish reliable normative data for Cog-First, allowing patient scores to be compared against a standardized reference population.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>Methods<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A cross-sectional study was conducted on 406 healthy French-speaking volunteers recruited from the Paris Brain Institute database. Each participant completed the seven Cog-First subtests under standardized conditions. A subsample of 95 participants repeated an alternative version of the test one month later to assess the test-retest effect. The influence of sex, age, education, and test version was analyzed using generalized linear models (GLMs). Correction formulas were derived to adjust scores and generate standardized percentiles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>Results<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sex, age, education, and test version significantly influenced several subscores. Test-retest analyses revealed a learning effect in four out of seven subtests. Corrected scores enabled the establishment of an automated standardization process integrated into the Cog-First software.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>Conclusion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This standardization provides reliable norms for the clinical interpretation of Cog-First results, supporting early detection of cognitive impairments and guiding patient care.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Clinical impact<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cog-First is an innovative neuropsychological tool that enhances the detection and management of cognitive deficits following brain injury.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Background Acquired brain injuries can lead to subtle cognitive impairments that are often difficult to detect, yet significantly influence long-term functional outcomes.
