New quick test could help diagnose ADHD and autism without reading skills
NCT ID NCT07531914
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new test called the Five Digits Test (FDT) to see if it can measure a person's ability to stop automatic responses—a skill often affected in ADHD and autism. The FDT does not require reading, making it useful for people with different language backgrounds. Researchers will compare the FDT to standard tests and daily-life questionnaires in 150 adults with or being evaluated for ADHD or autism.
