What triggers a seizure?

Seizures are primarily triggered by an abnormal discharge of electrical energy in the brain. This means that during a seizure, there is a sudden and excessive electrical activity in the neurons, leading to a variety of symptoms depending on which part of the brain is affected. This abnormal activity can disrupt normal brain function temporarily and can manifest in various physical symptoms, cognitive disruptions, or altered sensations depending on the seizure type.

While other factors like external stimuli, low blood sugar levels, fatigue, and stress can influence seizure thresholds or may serve as triggers in individuals with epilepsy, the fundamental cause of a seizure lies in the irregular electrical activity in the brain itself. Understanding this is crucial for recognizing the physiological basis of seizure disorders and highlights the importance of managing these underlying electrical disturbances in the brain for effective treatment and intervention.
