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.
Neurology and Neurosurgery. Causes of a Seizure. While the exact cause of some seizures can be hard to pinpoint, many seizures can be classified as either provoked or unprovoked. A provoked seizure would include traumatic injuries to the head, whereas an unprovoked seizure would include seizures caused by, for example, a congenital defect. Unprovoked (ânaturalâ) seizures: Some seizures may be caused by ânaturalâ phenomena occurring in the body, such as a congenital defect or a chemical imbalance. One example of this is a condition called GLUT-1 deficiency.
