Saccadic intrusions in paediatric concussion – is there a link to academic performance?

Saccadic intrusions in paediatric concussion – is there a link to academic performance?

A recent case report study identified saccadic intrusions present only during smooth pursuit and not during fixation, in children 10 to 15 years old who suffered a concussion. Saccadic instructions are involuntary conjugate saccades that interrupt fixation, a common symptom post mTBI. The study concluded that Gabapentin treatment reduced the magnitude of saccadic intrusions and the headaches reported especially while reading or concentrating in class.

These findings point to the importance of robust, comprehensive oculomotor testing to better understand academic difficulties post mTBI. Neurolign devices and software used in this study provided a powerful tool to objectively measure oculomotor deficits and track the effect of drug treatment post-concussion.
