What this trial studies

This study investigates whether providing additional time on standardized college entrance exams, such as the Brazilian National High School Exam (ENEM), benefits students with Attention Deficit Hyperactivity Disorder (ADHD) and those without. Participants will complete online questionnaires, undergo psychiatric evaluations, and perform neuropsychological tests. They will then take a mock ENEM test under both standard and extended time conditions to assess the impact of time on their performance.

Who should consider this trial

Good fit: Ideal candidates are Brazilian citizens planning to take college-entry standardized tests and who meet the inclusion criteria.

Not a fit: Patients with medical conditions or disabilities that hinder neuropsychological testing or those with certain psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved academic performance for students with ADHD and potentially benefit other students as well.

How similar studies have performed: Other studies have shown that extended time can improve test performance for students with ADHD, suggesting this approach may be beneficial.
