Symptom #3: Seizures
Seizures can occur as a manifestation of abnormal electrical activity in the brain. The neurons in the brain that communicate with each other through electrical signals misfire during a seizure, resulting in abnormal movements, behavior changes, abnormal sensations, changes in mental status, confusion, and loss of consciousness.
Low sodium levels can cause brain swelling. This is known as cerebral edema – a lack of sodium leads to the buildup of water around the brain. The excess fluid disrupts the ability of the neurons to transmit signals, causing a seizure.
