Correlation of tibial nerve SEPs with the development of seizures in patients with supratentorial cerebral infarcts.
In 40 patients with supratentorial non-haemorrhagic cerebral infarct, the findings in the tibial nerve SEPs recorded during the acute stage correlated significantly with the development of seizures during a 1 year follow-up period. Abnormality in the side-to-side difference of the P40-N48 amplitude was the finding with the highest correlation with the development of seizures: 87.5% of the patients were classified correctly as to the risk of seizures.
