The two most common categories are focal and generalized epilepsy. The epilepsy that a person has is determined by the location of the damaged neurons within the brain. Focal epilepsy is characterized by seizures that affect the mind instead of the body. A seizure of the mind can cause an epileptic person to see or hear things that are not there, or to cry or feel anger for no reason. This category of epilepsy is vast but not well known, so many people that suffer from focal epilepsies are often assumed to be on drugs, alcohol, or mentally unstable. Generalized epilepsy is characterized by seizures of the body. These seizures are more commonly known throughout the world. Generalized epilepsy can be split into two subcategories by the type of seizure a person suffers from. The two types of generalized epileptic seizures are tonic-clonic seizures and absence seizures. A tonic-clonic seizure is the most well-known type of seizure. During a tonic-clonic seizure, a person loses control of their body and starts convulsing uncontrollably. Absence seizures are the near opposite of tonic-clonic seizures. During absence seizures, a person’s body is frozen and they appear to be daydreaming. Though these seizures are virtually unnoticed, they make it difficult to complete work or pay
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.
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
This paper is on epilepsy and seizures. The human brain is the source of all human epilepsy. (Steven C. Schachter, Patricia O. Shafer, Joseph I. Sirven, 2013) What is epilepsy? Epilepsy is sometimes referred to a seizure disorder, though not all seizures are related to epilepsy. According to the website Stony Brook Medicine, the reason a seizure occurs is because of an unexpected surge of electrical activity in the brain. (Stony Brook Medicine, 2014) Due to the overloading of electrical activity, it causes short-lived disturbance in the messaging system between the brain cells. The word epilepsy approaches from a Greek word 'epi' signifying 'upon or above' and the Greek word
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
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 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.
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.
Seizures are classified into two broad categories primarily generalized and partial seizures. A generalized seizure is characterized by loss of consciousness. There are several sub types of generalized seizure. The first is an absence seizure, this usually consist of brief spells of staring. This type of generalized seizure usually begins in early childhood and diminishes as the child grows older. However, absence seizures may continue until adulthood in some individuals (McKean, 2012). Next, myoclonic seizures are characterized by quick jerking movements. Atonic seizures display a sudden loss of tone and individuals frequently experience injuries related to falls. Generalized tonic clonic seizures display a tonic extension of extremities followed by clonic jerking. There can be variations of this type of seizure activity demonstrating either more tonic motion or clonic (McKean, 2012). Partial seizures initiate when there is an abnormal firing of neurons within the cerebral cortex. This area within the cerebral cortex dictates the symptoms of the seizure activity. A partial seizure can develop into a general seizure if both hemispheres are involved (McKean, 2012). Partial seizures are subdivided into simple and complex. In a complex partial seizure, the individual loses conciseness and has symptoms like lip smacking, staring, picking at clothes, walking around aimlessly. In a simple partial seizure the individual is awake and aware of the episode. The individual may
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 is a brain disorder in which clusters of nerve cells also called neurons inside the brain signal unusually or in which case the brains neurological pattern also called the electrical pattern is disrupted. Neurons inside the brain usually generate electrochemical impulses that communicate with other neurons. In Epilepsy, the usual pattern of neurological activity becomes distorted, causing odd sensations such as behavioral and emotional, muscle spasms, sometimes convulsions and loss of consciousness can occur. Seizure disorders originate from a pathogenic process, head trauma, metabolic processes, exogenous or endogenous poisons, and a simple fever. Seizures may be a result from an exposure to many types of poisons such as lead and carbon monoxide but it can also
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.
Each of the types also present different clinically. There are two main types of epilepsy. The first type is generalized epilepsy and is not tied to a specific area of the brain, and the second is focal or partial epilepsy which begins in a certain lobe and highly developed areas. Generalized epilepsy is then further broken down into idiopathic and symptomatic. During idiopathic seizures the cause of the episode is unknown, and the brain is behaving normally between seizures. Whereas, during symptomatic seizures there is a known cause of the seizure which is due to a structural brain abnormality (“Pediatric Epilepsy & Seizures”,
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.
