Essay on Understanding Seizures

The cause of all seizures is unclear, but doctors have come up with some reasons why they may occur. Common forms of generalized epilepsy, absence attacks, and tonic-clonic seizures are sometimes caused because of an inherited instability. This is where the inherited instability in functioning of neurones is responsible for these disorders. It is still not understood just how this genetic defect works, it could be the abnormality is in the structure of the neurone's outer membrance, which could cause electrical instability.

People uneducated about Epilepsy may have confused thoughts on what it really is. People have these "notions," which are partly or entirely not true. So, throughout this research paper, these notions will be proven untrue, mostly by factual information given by

A sudden attack of neurons is a complex neurological disorder, deemed the term seizure. A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical brain activity.1 Epilepsy or seizure disorders affect about 1.8 percent of adults 18 years or older.2 Men present with their first seizure more often; 58%. Symptoms associated with seizures vary according to the brain region affected, and do not always indicate a seizure. Some symptoms involved are drooling, brief blackout, shaking of the entire body, and sudden falls.1 According to John Hopkins Medicine, there are generalized, absence, myoclonic, tonic-clonic, atonic, and partial seizures.3 Most times individuals with seizure activities

Epilepsy is due to an upset in brain chemistry, which means that the messages that travel between nerve cells or neurons become scrambled. Because of this, the activity of neurons is disturbed and results in a seizure or loss of consciousness. Many types of seizure can occur and epilepsy can affect anyone at any age.

Mainly, there are 2 types of seizures: Focal (partial) seizure and generalized seizure. Focal seizure starts in and affects a large part of one hemisphere or just a small area in one of the lobes. Focal seizure is sub-divided into Simple Focal Seizures

Epilepsy is a brain disorder in which individuals have recurrent seizures. Seizures can occur in children and adults of any age. There are around 50 million people in the world who has the disorder. Individuals in developing countries are at a higher risk for developing the disorder. Seizures occur due to hyper-excitability and hyper-synchronization of neurons. Action potential transmits messages and it leads to depolarization. When neurons are uncontrollably depolarizes because of hyper-excitability due to too little inhibition, it cause a seizure. Seizures can last from a few seconds to a few minutes. As spontaneously they can develop is also as fast and spontaneous they can end.

Epilepsy, also called seizure disorder, chronic brain disorder that briefly interrupts the normal electrical activity of the brain to cause seizures, characterized by a variety of symptoms including uncontrolled movements of the body, disorientation or confusion, sudden fear, or loss of consciousness. Epilepsy may result from a head injury, stroke, brain tumor, lead poisoning, genetic conditions, or severe infections like meningitis or encephalitis. In over 70 percent of cases no cause for epilepsy were identified. About 1 percent of the world population, or over 2 million people, are diagnosed with epilepsy.

Those seizures affect the whole body and brain of the patient, and are much more serious than partial or focal seizure, which only affects one muscle or one part of the body,

Neurons in the brain are extremely busy sending electrical signals from cell to cell telling the brain what to do. If these electrical signals are interrupted or abnormal, a seizure will occur. If it occurs throughout the brain, it is considered a generalized seizure (Grand Mal), and if it occurs in a localized area, it is called a partial seizure. If someone experiences more than two seizures, it is then considered epilepsy (AKA: Seizure Disorder).

Epilepsy is the name for several neurological disorders in which people have epileptic seizures. It affects an estimated 65 million people around the world (cureepilepilepsy.org) and varies greatly from case to case. There are several treatment options for patients as well as research for developing better ways to diagnose and treat epilepsy.

Epilepsy is a neurological disorder found in the central nervous system that causes different types of seizures that can be harmful, and may lead to death. In the central nervous system (CNS), the nerve cells become disturbed or agitated from their normality causing different behaviors to the person, and the loss of awareness or consciousness. The epileptic seizure can also cause muscle spasms, attacks, or different emotions. Every person has a different type of epilepsy seizure happening to them. Various people just stare and do nothing while others are twitching rapidly and cannot control it. Anyone that gets a seizure is going to be tested for epilepsy, being one of the top four neurological disorders.

In fact, nerve cells in the brain send out electrical impulses, which are very excessive. At the time of seizure, the brain can be described as an electrical storm of neurons, because they are discharged five hundred times faster per second that usual. If this happens, the person has a seizure. However, even though all seizures happen because of the same fact, there are over twenty different kinds of epilepsy. It is important to distinguish between the two common types, focal and generalized. A focal seizure affects only one specific area in the brain. Around fifty to sixty percent of all children and teenagers have focal seizures. It can happen that the focal seizure spreads and starts to involve other parts of the brain, as well. This is called a generalized seizure then. During a generalized seizure, the entire brain is involved and the seizure is therefore not limited to one part of the body, but includes the entire body. The most common kind of a generalized seizure is the tonic-clonic seizure (grand-mal). This seizures starts with a loss of consciousness and falling, followed by a tonic muscle stiffness, which goes over into the clonic phase, which is a rapidly contraction and relaxation of the muscles. The patient can be injured during the fall or cramp, if it occurs in a dangerous area. Overall, an epileptically seizure

Seizures are defined as “paroxysmal, uncontrolled electrical discharge of neurons in the brain that interrupts normal function” (Lewis, Dirksen, Heitkemper, Butcher, & Camera, 20011). Seizures can be caused by various things from head trauma to a disease process. There are several types of seizures. These include absence partial and generalized seizures. They can also vary in intensity ranging from mild to full blown. Seizures can cause severe complications and should be treated or the cause of the seizures corrected. (Lewis, Dirksen, Heitkemper, Butcher, & Camera, 20011).

underlying cause can be determined. Seizures occur as a result of abrupt, explosive, unorganized discharges of cerebral neurons. This causes a sudden alteration in brain function involving sensory, motor, autonomic and/or psychic clinical manifestations.

Seizures arise from excess excitation or loss of inhibition of the neurons and fast spread of these impulses over the brain.
