The brain’s electrical activity is periodically disturbed in seizure conditions which results in a degree of temporary brain dysfunction. For the brain to function normally, it requires an orderly, organized, coordinated discharge of electrical impulses. These electrical impulses enable the brain to communication with the spinal cord, nerves and muscles and with itself.
There are two basic types of seizures -- Epileptic seizure and Non Epileptic seizure. Causes of seizures may include high fever, brain infections, metabolic disorders, inadequate supply of oxygen to the brain, structural damage to the brain, accumulation of fluid in the brain, or some recreational drugs.
Seizures can cause involuntary changes in the body movement or function, awareness, weakness or behavior and can last from a few seconds to a status epilepticus -- a continuous seizure that will not stop with intervention. They are often associated with a sudden and involuntary contraction of a group of muscles and loss of consciousness, leading to severe pain in the muscles. However, it can also be less painful and result in subtle numbness of a part of the body, a long term or a short term memory loss, flashes or sparkling, sensing or discharging unpleasant odor similar to alcohol base produced by internal organs.
Some episodes are preceded by unusual sensations warning of an impending attack. About 2 percent of adults have a seizure at some time during their life. Two thirds of these people never have another one. Most commonly, seizure disorders begin in early childhood or in late adulthood. The condition can also be caused by certain mental disorders with symptoms that resemble seizures, called psychogenic non-epileptic seizures.
