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.
Electrolyte disorders frequently cause seizures (Table 1). Seizures are common in patients with sodium disorders, hypocalcemia, and hypomagnesemia (Victor and Ropper, 2001; Riggs, 2002). In such cases, seizures are usually generalized tonicâclonic, although partial seizures or other seizure types can occur. In all these cases, rapidly evolving electrolyte abnormalities are more likely to cause seizures than are those occurring gradually.
