Full Answer

Other symptoms of seizures include the patient having a bitter or metallic taste in his mouth, foaming at the mouth or drooling, and teeth clenching, states MedlinePlus. The patient may temporarily stop breathing and make grunting sounds.

The seizures that cause epilepsy are due to disturbances in the brain's electrical system, says WebMD. But not all seizures are due to epilepsy. Medical professionals refer to other types of seizures as pseudoseizures. The people who have these types of seizures have normal EEG readings and aren't helped by anti-epileptic drugs.

Very high blood pressure is called malignant hypertension, explains WebMD. A person who has this condition has blood pressure that is 180/120 or higher and is in the grip of a medical emergency. The condition comes on quickly and often damages organs. It is a complication of high blood pressure itself and is often brought on because the patient missed doses of his blood pressure medicine. It can also be brought on by kidney disease, the use of illegal drugs, adrenal gland tumors and spinal cord injuries.
