Seizures Research Paper

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.

Epilepsy is defined as "an occasional, an excessive and a disorderly discharge of nervous tissue induced by any process involving the cerebral cortex that pathologically increases the likelihood of depolarization and synchronized firing of groups of neurons” (Hughlings Jackson, 1889). To be classified as a generalized seizure the entire brain needs to be involved. One type of Generalized seizure is the ’grand mal’ seizure or tonic-clonic seizure, which also requires a loss of consciousness, equilibrium, rigidity tremors, and possibly resulting in hypoxia causing brain damage.

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

Seizures may arise at any stage of age, but certain periods of life present a higher risk for their emergence. The frequency of seizures in the epileptic population varies widely. Some epileptic experiences only two seizures in a lifetime, and other may suffer 100 of attacks daily. Approximately 25 percent of epileptic experience seizures that are uncontrolled by current forms of

The constant firing of neurons in the brain during normal everyday actions is called electrical brain activity. Seizures are changes in the brain's electrical activity, which can "cause dramatic, noticeable symptoms or even no symptoms at all (healthline.com)." During a seizure, nerve cells leave their regular positions where they delivered orders from the brain to other parts of the body. The neurons fire in

Generalized seizures affect both of the cerebral hemispheres from the beginning of the seizure. They cause loss of consciousness, for a long period of time or briefly.

I remember three years ago, my family and I went to Palm Springs for the first time. That night I was fascinated, not from the beauty of the Palm desert, but the fact that my brother would have a seizure exactly twenty minutes after falling asleep. His brain acted like a clock-working machine. Exactly twenty minutes. Now what chemicals could his body be producing after falling asleep for twenty minutes that would trigger the seizure, I do not know, but I wanted to find out. Moreover, I had to alway keep an eye on my brother throughout the day, especially after he started losing control of his body and falling down without warning. The first time he experienced this, he could have cracked his head open if my father was not nearby to catch is forceless body. There is nothing more stressing than waking up nervous for tests and project while witnessing my own brother shaking uncontrollably. These are some things that clouded my thoughts and focus everyday when I was trying to pay attention in class. Right now, I could not be more than thankful that my brother hasn't had a seizure for months. The changes started taking place right after Christmas of last year, just like a Christmas

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 seizure is an instantaneous change in behavior provoked by electrical hyper synchronization of neuronal networks in the cerebral cortex. Most seizures can be categorized as either focal or generalized according to whether the onset of electrical activity involves a focal region of the brain or both sides of the brain simultaneously. The clinical manifestations of seizures vary based on the location of the seizure in the brain and the amount of cortex that is involved. Focal seizures are further classified by whether consciousness is altered or not during the event. Types of seizures include, focal seizures with retained awareness: This vary from one person to another, it’s dependent entirely on the part of the cortex that is disrupted at the commencement of the seizure; a seizure that begins in the occipital cortex may result in flashing lights, while a seizure that affects the motor cortex will result in rhythmic jerking movements of the face, arm, or leg on the side of the body opposite to the involved cortex also called Jacksonian seizure, a seizure that begins in the parietal cortex may cause distortion of spatial perception, and a seizure that begins in the dominant frontal lobe may cause sudden speech difficulties. The symptoms

Epilepsy has been defined conceptually by International League Against Epilepsy (ILAE) in 2005 as “A disorder of the brain characterised by enduring predisposition to generate epileptic seizures, and by the neurobiologic, cognitive psychological and social consequences of this condition.” It requires that at least one epileptic seizure occurs to define epilepsy. In addition to the conceptual definition, ILAE has updated its practical definition in 2014. Any of the three conditions described defines epilepsy. The three conditions are: “1) At least two unprovoked (or reflex) seizures occurring >24 hours apart; 2) One unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk

Epilepsy is a disorder that causes seizures, and can prevent you from being able to a lot of things in life. Today we will be talking about how epilepsy develops and can occur. Then we will talk about what living with epilepsy is like and what it looks like, also what it’s like living with a person with epilepsy. Lastly we will learn the possible preventions and treatments for epilepsy. Epilepsy doesn’t have developmental stages; however it can worsen or change.

Absence seizures, rare in adults, are characterized by a sudden, momentary loss or impairment of consciousness. Overt symptoms are often as slight as an upward staring of the eyes, a staggering gait, or a twitching of the facial muscles. No aura occurs and the person often resumes activity without realizing that the seizure has occurred.

Although the association between epilepsy and cognitive deficits has been documented in numerous studies, this relationship has remained poorly explored in children with epilepsy (Krause et al. 2008). The impact of epilepsy on developing

Epilepsy can happen to anyone of any age. The largest(47%) percent of people, developing epilepsy for the first time, being children from birth to nine years of age. The next largest age group would be ten year olds to ninteen year olds at 30%. The least amount of first time seizures comes from the forty plus age group. (According to EFA publications) Over 2.5 million people suffer from epilepsy. The international league against epilepsy describes a seizure as an alternative term for "epileptic attack". Seizures vary in there length and severity. A "tonic-clonic" seizure can last for one to seven minutes. " Absence seizures usually last for a few seconds. However, complex partial seizure" may last for thirty seconds or two

Some symptoms of epilepsy are having abnormal smells or taste, butterflies in the stomach, or hallucinations. Some people also have déjà vu or jamais vu, others have the inability to speak, a convulsion, or even an intense feeling a seizure is going to happen. Partial seizure symptoms include involuntary muscle twitching, vision or sensory changes, dizziness, and if it’s a complex partial, the person may lose conciseness. All people have different types of seizures. The two basic types are epileptic and nonepileptic. There are lots of other types. One of them is a partial seizure. Simple partial seizures only effect a small part of the brain whereas Jacksonian seizure effect the whole body by spreading around it. In complex partial seizure the person’s conscience is impaired or they could have the rare Epilepsia Partalis Continua. Like the complex partial seizure, generalized seizures may lose conscience. Losing conscience doesn’t happen with generalized tonic-clonic seizures. Instead the body muscles alternate between contracting and relaxing. Muscle contraction also occurs in status epilepticus. Status Epilepticus is a most serious disorder and it doesn’t stop. During it the person can’t breathe adequately and their body temperature increases. With reflex epilepsy the seizure can be triggered with repetitive sounds, flashing lights, video games, and even by just touching certain parts of the person’s body. Two other types of seizures are Unprovoked seizure, which are created by natural causes, genetic factors, and metabolic imbalances, and Provoked seizures, which are caused by a brain injury or a stroke. These different seizures are treated varying with reason of the seizure. Some are treated with drugs and if the drugs don’t work the doctors do surgery. Other seizures are treated with devices, dietary changes, or anticonvulsants, which stop about one third of people’s
