Seizures in adults can be caused by a variety of factors, including:

• Brain injury: Seizures can be caused by a brain injury, most often from a stroke, damage, infection, or tumor.

• Epilepsy: Less commonly, seizures can be caused by a seizure disorder called epilepsy.

• Withdrawal: If you stop using alcohol or some drugs, you can have side effects called withdrawal. Withdrawal sometimes causes seizures.

• Medications: Some medicines also can cause seizures. If you take regular medicine, make sure you have a plan with your doctor before you stop taking it.

• Imbalances: Seizures can be caused by abnormal levels of sodium or glucose in the blood.

• Infections: Seizures can be caused by infections such as meningitis or encephalitis.

• Brain tumors: Brain tumors can cause seizures.

• Genetic changes: Some types of seizures may be caused by genetic changes.

• Other factors: Seizures can also be caused by factors such as high fever, lack of sleep, or extreme stress.

Its important to note that sometimes no cause or trigger for a seizure will be found. If you or someone you know experiences a seizure, its important to seek medical attention to determine the cause and appropriate treatment.
