People most often associate violent twitching, falling to the floor
and drooling with epilepsy. However the described event is only one
kind of an epileptic seizure, which is called a tonic-clonic seizure.
There are many other kinds of seizures, and each has different sets of
signs and symptoms.
During generalized seizures the whole brain is affected and the
initial symptom is loss of consciousness. This category includes such
seizures as absence seizure, myoclonic seizure, and atonic attack.
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, and not accompanied by loss of
consciousness.
Epilepsy occurs when nerve cells in the brain fire electrical impulses
at a rate of up to four times higher than normal. This causes a sort
of electrical storm in the brain, known as a seizure. During a seizure
the normal neuronal activity, which is usually responsible for human
thoughts, feelings, and actions of glands and muscles, becomes
disturbed and as a result strange behavior, convulsions and loss of
consciousness might occur.
Epilepsy knows no geographical, racial or social boundaries. It occurs
in men and women and can begin at any age, but is most frequently
diagnosed in childhood or old age. Anyone can be affected by seizures.
In fact, up to 5% of the world's population may have a single seizure
at some time in their lives, but a person might be diagnosed with
epilepsy only after they had two unprovoked seizures. From many
studies around the world it has been estimated that the m...

Epilepsy is not contagious and is not caused by mental illness or
mental retardation. Many people with epilepsy have normal or
above-average intelligence. Famous people who are known or rumored to
have had epilepsy include the Russian writer Dostoyevsky, the
philosopher Socrates, the military general Napoleon, and the inventor
of dynamite, Alfred Nobel, who established the Nobel prize. Many
people with epilepsy lead productive lives. Many medical and research
advances in the past two decades have led to a better understanding of
epilepsy and seizures than ever before.
On a cellular lever, HCM can cause the cells to become disorganised and lost. Under a microscope, a normal Cardiac Muscle cell appears parallel and organised, while a cell affected by HCM will appear irregular and disorganised. This disorganisation can create changes and altercations in the signals sent and received through the lower chambers of the heart, which in turn can lead to an abnormal heart rhythm, known as ventricular
The thickening of the muscle cells do not necessarily have to change the size of the ventricles, but can narrow the blood vessels inside the heart. Hypertrophic cardiomyopathy can be grouped into two categories: obstructive HCM and non-obstructive HCM. With obstructive HCM, the septum (the wall that divides the left and right sides of the heart) becomes thickened and blocks the blood flow out of the left ventricle. Overall, HCM usually starts in the left ventricle. HCM can also cause blood to leak backward through the mitral valve causing even more problems. The walls of the ventricles can also become stiff since it cannot hold a normal amount of blood. This stiffening causes the ventricle to not relax and entirely fill with
Epilepsy is a neurological disorder that affects the brain causing people to have seizures. A seizure is a big disruption of electrical communication between neurons, leading to the temporary release of excessive energy in a synchronized form Epilepsy is very unpredictable. Having a seizure disorder doesn't mean that you can only have one type of seizure. People can have many different types of seizures; it can vary on the person. In some cases depending on the type of seizures someone may have they can grow out of them. (“Epilepsy Foundation." What Is Epilepsy? N.p., n.d. Web. 09 May 2014.)

Epilepsy, also known as “seizure disorder,” or “seizure attack,” is the fourth most common neurological disorder known to mankind, affecting an estimated 2.3 million adults and 467,711 children in the United States. Unfortunately this disorder is becoming far more common and widespread worldwide. This staggering number of cases of people suffering from Epilepsy also involves an average growth rate of 150,000 new cases each year in the United States alone. Generally, many of the people who develop who are a part of the new are mainly either young children or older adults. Your brain communicates through chemical and electrical signals that are all specialized for specific tasks. However, through the process of communication, chemical messengers, also known as neurotransmitters can suddenly fail, resulting in what is known as a seizure attack. Epilepsy occurs when a few too many brain cells become excited, or activated simultaneously, so that the brain cannot function properly and to it’s highest potential. Epilepsy is characterized when there is an abnormal imbalance in the chemical activity of the brain, leading to a disruption in the electrical activity of the brain. This disruption specifically occurs in the central nervous system (CNS), which is the part of the nervous system that contains the brain and spinal cord. This causes an interruption in communication between presynaptic neurons and postsynaptic neurons; between the axon of one neuron, the message sender and the dendrite of another neuron, the message recipient. Consequently, the effects that epileptic seizures may induce may range anywhere from mild to severe, life-threatening ramifications and complications. There are many different types of seizures associa...

Epilepsy is a very common neurological disorder. Some reports estimate that five in one-thousand people suffer from this problem. Throughout history, people with epilepsy have been shunned or considered inferior. Even today, ignorance leads many people to treat the epileptic as "abnormal" or "retarded". Although the etiology of epilepsy is still not fully understood, it is quite treatable due to advances in modern medicine.
Porphyria is caused when heme is disrupted. The synthesis of heme involves eight different enzymes, which creates eight different forms of porphyria. The disruption of heme causes porphyrin to build up in various spots around the body. It eventually causes problems in the liver, which will turn the urine dark. This is why most cases of porphyria have liver problems (American Porphyria Foundation).

Not everyone who has a seizure has epilepsy. Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures. Unprovoked means that there is no immediate cause for the seizure, such as a fever, an infection of the brain, or head trauma. Nearly 10 percent of people will have a seizure during their lifetime; most of these are provoked seizures during an acute illness or condition. These people may never have epilepsy. There are two types of seizures people can have. One is partial seizure or focal they begin in one part of the brain. They cause varied symptoms auras which is a funny feeling in your stomach, staring, chewing, lip smacking, shaking, or stiffness in parts of the body. Generalized seizures are when the entire brain is effected. This causes loss consciousness. One type is grand mal is when the body stiffens and jerks. Another type is petit mal, which is momentary loss of consciousness without abnormal body movement. Some factors of this are infections of the brain this includes meningitis, encephalitis, and brain abscess. Strokes are also a risk of epilepsy. Also alcohol can cause seizures for heavy drinkers when they stop drinking abruptly (withdrawal seizures) and also have a good chance of epilepsy. Epilepsy can also cause brain tumors usually they are slow growing and don't affect them for years. Some other factors that cause epilepsy is age the risk of seizures is higher in young children. Also gender epilepsy is higher in males than in females. The most common treatment for epilepsy is the daily use of anticonvulsant or antiepilectic drugs to prevent seizures. These medications act on brain signals to limit hyperexcitability. While medications do not cure epilepsy, they allow many people to live normal, active lives. Other treatments are vagus nerve stimulation this treatment involves electronic stimulation of the brain using an implanted device like a pacemaker. Another is epilepsy surgery this is when a part of the brain that is causing the seizures is removed so that it prevents it from spreading to anther part of the brain.
It was a cold, rainy day. I could see most of the kids at the bus stop had winter coats and hats. The clouds were particularly low in the sky. After evading the numerous puddles in the road, I reached the bus stop and walked up to a group of friends. A girl in my class spotted me and asked, "Are you going to the dance tomorrow?"
Epilepsy is a condition characterized by recurrent seizures which are unprovoked by any immediately identifiable cause (Hopkins & Shorvon, 1995). It is also known as a seizure disorder. A wide range of links and risk factors are associated with the condition, but most of the time the cause is unknown. Epilepsy is one of the most common neurological disorders, affecting approximately two and half million people in the US and about 50 million worldwide. Though seizures can occur at any age, epilepsy is most commonly seen in children and the elderly. Most respond well to treatment and can control their seizures, but for some it is a chronic illness. A clinical diagnosis is the first step to finding a potential cure for the disorder.
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.
Absence seizure also known as “blank spells” are a common seizure in childhood epilepsy. Absence seizures fall under the generalized category because there is a loss of consciousness that takes place. The two subclasses of absences seizures are typical and atypical absence seizures. Typical seizures are characterized by an abrupt interruption in activity in which the child may become still. Their eyes will remain open and they appear to stare straight ahead. Typical absence seizures can happen dozens to hundreds of time in a day but because they are known to be very brief (about forty seconds) they are often unnoticed by parents, peers, and teachers. Atypical absence seizures are usually longer in duration and tend to have a gradual start
