Epilepsy: Nervous System

Seizures or epilepsy are brain disorders where the person has repeated convulsions over a period of time. They’re episodes of disturbed brain activity that cause changes in attention and behavior. Seizures are considered the most common observed neurological dysfunction in children. They are very sudden intermittent episodes of altered consciousness lasting seconds to minutes and include involuntary tonic (stiffening of muscles) and clonic (altering contraction and relaxation of muscles) movements.

Seizure are uncontrolled or sudden abnormal electrical activity in the brain which causes abnormal motor and sensory activity and where the patient becomes unconsciousness. It is caused by the depolarization of the neurons. Any changes that takes place in our body that may be internal or external it can easily stimulate the irritable neurons. Seizure last for a second or a minute, in which the neurons stops unexpectedly. The pattern of electrical activity or brain waves during a seizure can be seen in EEG, by knowing what type of seizure. There are different

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.

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.

Seizure is an abnormal electrical activity in a person's brain, seizures can occur on a daily basis. Others have them once every couple of months and many may have them every now and then or never if treated with medication. There are many types of seizure, for some seizures a person may become very stiff leading them to pass out and their whole body shakes, full body-seizures can reduce breathing, bite their tongues causing them to bleed,

Seizures occur when abnormal signals from the brain and changes the way the body functions. Many people have seizures but they have different effects on them. Some people have a little shaking of their hands and do not lose consciousness, while others have a lot of shaking and do lose consciousness. While seizures have a range of life changing effects for adults, more needs to be focus on children.

When I was eight years old I learned what epilepsy was. My family was in the car driving to get dinner, with my dad driving. We were stopped at a stop light, and when it turned green we never moved. My mother looked over at my dad and realized he was having a seizure. At the time I did not know what that was; all I remember is a blur of my sister calling 911, and us going to the hospital. It was one of the scariest moments of my life; I thought my dad was dying. Later that night my mom explained to us what a seizure was, and that he was going to be okay. This was the first time my dad had a seizure, and the doctors did not know why. He was sent home from the emergency room that night with no answers and a shaken up family.

A seizure is a disruption of the electrical activity between neurons in the brain. The resulting chemical changes can lead to a surge of electrical activity causing a seizure. Aside from trauma to the brain due to injury, or

It was believed a seizure in the brain caused by the electric current would stimulate the release of neurotransmitters, and would allow the brain to reorganize to function correctly (Nasar). Neurotransmitters are chemical substances that transmit signals that facilitate cell to cell communication throughout the nervous system, and play a key component in the biological paradigm for treatment of schizophrenia. At this early stage of understanding schizophrenia’s pathology, it was believed these chemicals were imbalanced and shocking the brain would force a rebalance of these vital chemicals. Once rebalanced, it was hypothesized the patient would no longer suffer from schizophrenia (Tharyan, 2005). The insight into treating neurotransmitter imbalances in patients diagnosed with schizophrenia began the treatment path to present day antipsychotic pharmaceutical drug therapy. While the actual effects of electroshock therapy on patients with schizophrenia are unclear, it is still used today to treat schizophrenic patients who are resistant to pharmaceutical drug therapy. Electroshock therapy was the utilization of insulin coma therapy and electroshock therapy to treat schizophrenia were successful partly due to the required hospital admittance and doctor administered methodology. In both treatments the patients were required to be admitted into a hospital and were not responsible for administering the treatment themselves. While both treatment methods were viewed as inhumane and

Epilepsy Research Paper 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.

Epilepsy is not what you think. It is a complicated disease, a disease that doesn't just affect one type of person or age. Over fifty million men, women, and children cope with this disease daily. Epilepsy is a mysterious disease to those who are unfamiliar and uneducated about the disease. Many people have preconceived notions about Epileptics. Researching the topic thoroughly, the five preconceived notions I explored have been proven to be false.

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.

Any type of injury related to your brain could cause you to have an epilectic seizure. These could include lack of oxygen during delivery of a baby, injury to the head at any age, injury to the brain caused by stroke.

Glial cells deliver neuroactive molecules and adjust synaptic transmission through modifications in ion channels, gap junctions, receptors, and transporters (4). Shape and function of glial cells change considerably in various kinds of epilepsy. Dysregulation of water and ion channel expression, variations in secretion of neuroactive molecules, and increased activation of inflammatory pathways as well as reactive gliosis Morphologic changes include (4). It has been suggested that epilepsy has an astrocytic origin (8). Prolonged neuronal depolarization and epileptiform discharges are resulted from direct stimulation of astrocytes (9) .

Epilepsy is a condition in which a person has two or more seizures affecting a variety of mental and physical functions. Epilepsy is one of the oldest conditions of the human race. Epilepsy Awareness is important because Epilepsy is a widely misunderstood disorder. The reason that Epilepsy has been misunderstood has been mainly due to research not being conducted until the middle of the nineteenth century. There are six main types of seizures and many treatments that can assist an epileptic patient. Many facts and myths exist about a person who has Epilepsy, which, is why it is an important disorder to understand. A person living with Epilepsy can typically have a normal life after seeking medical advice from doctors.
