The aim of this study was to examine whether it was possible by a reaction time (RT) test to predict if a patient was to complain of sequelae after a cerebral concussion. 55 patients had an RT test performed 1–5 days after concussion. The test showed a significant ( P < 0.02) prolongated RT in patients having postconcussional sequelae (median 186 ms) after 1 month (27 patients, 49%) compared to the patients without sequelae (median 168 ms). Patients with sequelae after 3 months (12 patients, 22%) also had a prolongation of RT (median 183 ms) although non‐significant. These results supports a structural organic etiology for postconcussional sequelae.
