Prediction of post-concussional sequelae by reaction time test

|May 1, 1987
Summary
Reaction time (RT) tests can predict post-concussion syndrome. Patients with prolonged RTs 1-5 days after a cerebral concussion were more likely to experience long-term sequelae.
Area of Science:
- Neurology
- Neuroscience
- Sports Medicine
Background:
- Cerebral concussions can lead to persistent post-concussive symptoms.
- Predicting the likelihood of developing sequelae after concussion is clinically important.
Purpose of the Study:
- To determine if reaction time (RT) testing can predict post-concussional sequelae.
- To investigate the relationship between early RT measurements and long-term outcomes after concussion.
Main Methods:
- 55 patients underwent reaction time (RT) testing 1-5 days post-concussion.
- RT measurements were compared between patients who developed sequelae and those who did not at 1 and 3 months.
Main Results:
- Patients with post-concussional sequelae at 1 month showed significantly prolonged RTs (median 186 ms) compared to those without sequelae (median 168 ms; P < 0.02).
- A non-significant RT prolongation was observed in patients with sequelae at 3 months (median 183 ms).
Conclusions:
- Early reaction time (RT) testing may serve as a predictive tool for identifying patients at risk of developing post-concussional sequelae.
- These findings suggest a potential structural or organic basis for post-concussional symptoms.
