An epileptic seizure is a brief episode of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain also know as brain discharge. Photosensitive epilepsy is the name for seizures triggered by information processed by the eyes. This is when seizures are triggered by certain rates of flashing lights or contrasting light or dark patterns. This information all passes through the eye into a part of the brain called the visual cortex. The visual cortex then sorts out the images received by the eye In photosensitive epilepsy, genetics plays an enormous role. About one in one-hundred people in the U.S. have epilepsy. About 3% to 5% of those people have photosensitive epilepsy. Children and adolescents ages 7 to 19 are more likely to have photosensitive epilepsy. The common rates at which can trigger triggers seizures are from 3-30 hertz (flashes per seconds), but it all depends on the individual’s tolerance. While some people are sensitive at up to 60 …show more content…
There are many different types of seizures. People with photosensitive epilepsy typically have what's called a "generalized tonic-clonic seizure." This is also known as a convulsive seizure. A tonic-clonic seizure should last no more than five minutes. Symptoms include loss of consciousness causing the patient to fall to the ground, muscles contract and body stiffens, breathing pattern changes, patient bites tongue and inside of cheeks, limbs jerk or twitch as muscles tighten and relax, loss of bladder control. When the seizure ends, the muscles relax and the person slowly regains consciousness. After the seizure, the person may be confused, feel tired, memory loss for a short time, have a headache, feel sore, recovery time varies. Some people are able to return to normal activity soon after a seizure. Others may need to
Many people with epilepsy usually have more than one type of seizure and may have other symptoms of neurological problems as well. The cause of epilepsy varies by age of the person, but the majority of the time the cause is unknown. Common causes of seizures by age in Elizabeth Otte’s case would be congenital conditions (Down’s syndrome; Angelman's syndrome; tuberous sclerosis and neurofibromatosis), genetics, head trauma, and progressive brain disease which is rare (Schechter & Shafer, Ltd., 2013, p.1). The diagnosis of epilepsy is based on medical history of the patients including family history of seizures. They ask several of questions to figure of what type of seizures the patients could possibly be suffering from. Doctors then preform test such as EEG, take blood, and study images of your brain. Epilepsy is treated by a neurologist specialist that may or may not subscribe medication depending on the severity and frequency of the seizures. Also treatment can be a change in the patients’ diet or
Seizures occur because of sudden surge of electrical activity in the brain. This cause is a temporary and disturbed in the messaging system between brain cells. Epilepsy may occur as a result of a genetic disorder or n acquired brain injury, such as trauma or stroke. There are four different kinds of seizures that can occur. Simple partial seizure, which is when the patient is conscious during the seizure in most cases, and the patient, is aware of his/her surrounding even when the seizure is in progress. Complex partial seizure is when the patient is conscious is impaired. The patient will generally not remember the seizure and if he/she does the recollection of it will be vague. Generalized seizure is when both halves of the brain have epileptic activity and the patient conscious is loss. Secondary generalized seizure is when epileptic activity starts as a partial seizure but then spread to both halves of the brain. The main symptom of epilepsy is repeated seizures. But, there are other symptoms such as short spells or black out or confused memory, panic or become fearful, repetitive movement that seem inappropriate, short period the person is unresponsive to instructions or questions etc.… There is no cure for epilepsy but overtime you can help it get better or find ways to adjust to it. You can also take medication, gob through surgery etc.… Epilepsy was a main point in the book because the main character Lia Lee was diagnosed with it. Her culture believed that it was a blessing rather than a disorder. Because of her culture it was impossible for Lia to be treated the way she supposed to be treated. Her parents did take her to get treatment and medication but they also utilized traditional healing methods. The family believed that little medicine and treatment was okay but not too much or that would stop the spiritual healing. In our presentation we talked
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.)
Photoreceptor Damage: Causes and Possibilities. Over 10,000,000 people around the world suffer from some sort of blindness or handicap due to photoreceptor damage. These effects can be caused by a number of afflictions, including retinitis pigmentosa, macular degeneration, and tumors. These illnesses vary in severity, from being a mere hindrance to completely blinding the individual.

Today we are here trying to figure out why is it that the color blue affects our sleep cycle. The electronic devices such as televisions, cell phones and tablets to name a few with screens in numerous sizes that are used every day may be the cause of many people’s sleep deprivation. There are various symptoms that can grow and disrupt our sleep as well as have long time serious effects on us for the future. Through-out the years there have been experimenters who have participated in this study to find out the cause for this action, in which we will analyze today. By the end of this study, we will have our result and understanding why we cannot sleep while this light is on. We can also come up with a way to turn this negative action and make it a positive one and also how it can better our lives. Blue light can affect sleep in any age range.
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 characterized by uncontrolled excessive activity of either a part of, or all of the central nervous system. A person who is predisposed to epilepsy has attacks when the basal level of excitability of the nervous system rises above a certain critical threshold. As long as the degree of excitability is held below this threshold, no attack occurs. Basically, epilepsy can be classified into three major types: grand mal, petit mal, and focal or partial epilepsy.
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.
Later, the doctors told me I had epilepsy, specifically the type known as grand mal. Immediately, the doctors put me on some medications to prevent the seizures. They also gave my parents a bunch of packets of information about epilepsy. When I got older, some of those packets informed me that 20-25 million people have suffered from an epileptic seizure. Many people grow out of childhood epilepsy or they take medicine to control it. However, there is still a risk of having a seizure even if you take medication. Over the past few years, I have become increasingly aware of the chance of a seizure at any time.
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 is a disorder of the brain characterized by an enduring predisposition to generate epileptic seizures,1 and by the neurobiological, cognitive, psychological and social consequences of this condition. An epileptic seizure is a brief disturbance of consciousness, behavior, emotion, motor function, or sensation that is due to abnormal electrical discharge in the brain.2 In partial-onset epilepsy, these bursts of electrical activity are initially focused in specific areas of the brain, but may become more generalized, with symptoms varying according to the affected areas. Epilepsy is the most common serious neurological condition in the UK.3 The World Health Organization (WHO) estimated its prevalence to be affecting approximately 5-8 per 1000 people.4 Anti-epileptic drugs (AEDs) are the major therapeutic option. Over a dozen AEDs have been introduced in the last 2 decades (Table 1.1).
Exposure to some type of lights, especially the flashing lights can cause seizures in people with epilepsy. In fact, exposure to some visual patterns or flashing lights causes seizures in about 3% of epileptic people. This condition is usually called photosensitive epilepsy (Harding & Harding, 2010). This section of discussion discusses the effects of light or visual sensors to the disabilities and specifically the people with epilepsy.
For the purpose of this assignment the experience of attending Electro-Convulsive Therapy will be discussed. It will include rationale for the procedure, an account of the procedure and the student nurses reflection on the experience using Gibbs’ model of reflection (Jasper 2003). Electroconvulsive therapy (ECT) is a medical treatment for severe mental illness in which a small, carefully controlled amount of electricity is introduced into the brain. This electrical stimulation, used in conjunction with anaesthesia and muscle relaxant medications, produces a mild generalised seizure or convulsion (Mankad et al 2010).
