Continuous monitoring devices and seizure patterns by glucose, time and lateralized seizure onset.

OBJECTIVES

To investigate if glucose levels influence seizure patterns.

MATERIALS AND

METHODS

In a patient with RNS/NeuroPace implanted bi-temporally and type 1 diabetes mellitus, seizure event times and onset locations were matched to continuous tissue glucose.

RESULTS

Left focal seizure (LFS, n = 22) glucoses averaged 169 mg/dL, while right focal seizure (RFS, n = 23) glucoses averaged 131 mg/dL (p = 0.03). LFS occurred at mean time 17:02 while RFS occurred at 04:23. LFS spread to the contralateral side (n = 19) more than RFS (n = 2).

CONCLUSION

Seizure onset laterality and spread vary with glucose and time of seizure.
