Seizures occur when one or more parts of the brain has a burst of abnormal electrical signals that interrupt normal brain signals. Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure. Some common causes of seizures in adults include:
-
Epilepsy: This is the most common cause of seizures in adults. Epilepsy is a neurological disorder that causes recurrent seizures.
-
Brain injury: Seizures can happen after a stroke or a head injury. A new, active brain injury, such as head trauma, can cause bleeding in an area of the brain or a new stroke.
-
Infection: Seizures may be caused by an infection such as meningitis or encephalitis.
-
Fever: A high fever can cause a seizure, known as a febrile seizure.
-
Lack of sleep: Seizures can be triggered by lack of sleep.
-
Low blood sodium: This can happen with medicine that makes you urinate.
-
Certain medications: Certain medicines that treat pain, depression or help people stop smoking can make it easier for seizures to happen.
-
Metabolic problems: High or low blood sugar levels, hormonal changes, and metabolic problems can also cause seizures.
Its important to note that sometimes the cause of a seizure is unknown. If you or someone you know experiences a seizure, its important to seek medical attention to determine the cause and receive appropriate treatment.
