What is pathophysiology of convulsion?

Answer 1

Seizures are paroxysmal manifestations of the electrical properties of the cerebral cortex. A seizure results when a sudden imbalance occurs between the excitatory and inhibitory forces within the network of cortical neurons in favor of a sudden-onset net excitation. If the affected cortical network is in the visual cortex, the clinical manifestations are visual phenomena. Other affected areas of primary cortex give rise to sensory, gustatory, or motor manifestations. The pathophysiology of focal-onset seizures differs from the mechanisms underlying generalized-onset seizures. Overall, cellular excitability is increased, but the mechanisms of synchronization appear to substantially differ and are therefore discussed separately.

Answer 2

Convulsions are caused by abnormal electrical activity in the brain, resulting in uncontrollable muscle contractions. This can be due to underlying conditions such as epilepsy, brain injury, infections, or metabolic imbalances. The exact pathophysiology can vary depending on the underlying cause.
