Can seizures cause hyponatremia?
Hyponatremia represents a frequent cause of epileptic seizures, as shown in a recent prospective observational multicenter study where acute epileptic seizures and focal neurological deficits were identified in 5% of patients with severe (<125 mEq/L) hyponatremia.

Can seizures be caused by dehydration?
Becoming extremely dehydrated — defined by the World Health Organization as losing more than 10 percent of your body weight in fluid — can lead to injury or fatal complications, and it requires an ER visit. Seizures, cardiac arrhythmia, or hypovolemic shock can occur because your blood volume is too low.
Do seizures cause hypernatremia?
HYPERNATREMIA. Hypernatremia is defined as a serum sodium concentration in plasma >145 mEq/L. Whereas hyponatremia may cause seizures, hypernatremia is more likely to be a result of seizure activity (e.g., generalized tonic–clonic seizures). Intracellular glycogen is metabolized to lactate in muscle during seizures.
Why do convulsions happen?
Causes. Convulsions are the result of abnormal electrical activity in the brain. The specific cause is often not clear. Convulsions can be caused by specific chemicals in the blood, as well as infections like meningitis or encephalitis.
What is the difference between seizures and convulsions?
A convulsion is a general term that people use to describe uncontrollable muscle contractions. Some people may use it interchangeably with the word “seizure,” although a seizure refers to an electrical disturbance in the brain. Seizures may cause a person to have convulsions, but this is not always the case.
