Gases in Earth's atmosphere absorb about 90 percent of this heat and radiate it back to the surface, which is warmed to a life-supporting average of 59 F (15 C). This very helpful process is called the greenhouse effect.
Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure; this includes a high fever, low blood sugar, alcohol or drug withdrawal, or a brain concussion. Under these circumstances, anyone can have one or more seizures.
Epileptic: These seizures have no apparent trigger (that is, they are unprovoked), and they occur repeatedly. Epileptic seizures are called a seizure disorder or epilepsy. What causes epileptic seizures is often unknown (called idiopathic epilepsy). But they may be caused by various brain disorders, such as structural abnormalities, strokes, or tumors. In such cases, they are called symptomatic epilepsy.
