While caffeine consumption is a daily habit for many people, it can become a little more complicated for those with a central nervous system disorder like epilepsy. That’s because caffeine interacts with certain brain signals, and seizures occur when there’s an imbalance of electrical activity in the brain.

Potential Links Between Caffeine and Seizures

Caffeine acts as a stimulant for the brain, which, along with the spinal cord, is part of the central nervous system. Stimulants excite or arouse these parts of the body. But researchers are still gaining an understanding of the relationship between caffeine, epilepsy, seizures, and anti-seizure medications.

Large Amounts of Caffeine and Increased Seizure Risk

Excessive caffeine intake can be risky for anyone, especially those with seizures.

Experts say that consuming more than 1,200 milligrams (mg) of caffeine—which would equal roughly 12 cups of coffee—within a short time can lead to dangerous side effects like seizures.
