Morse Code Project Student Name Course Title Instructor Institution Affiliation Date Introduction 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. Light Sensitivity Implications Sensitivity to flashing light is very common to young individuals include the adolescents and children. It is also common in the children with generalized epilepsy and commonly …show more content…
Low brightness (less than 20%) cannot cause the seizure to the affected individuals while high brightness (above 60%) can cause seizures. Sharp contrast with the lighting at the background can trigger the seizures in people with epilepsy. A typical example is the flashing light experience during the mid-night darkness. Though the brightness and frequency of the flashing light may be low, the contrast in this example is very high thus leading to the seizures (Lopes da Silva & Harding, 2011). Distance from the flashing light: a distance of 2 feet or more is safe and can cause minimal effect to the people with epilepsy. However, very close distance (less than two feet away) can trigger the seizures. Therefore, there is need for the disable individuals to stay at least two feet away from the flashing light and in a well-light environment. To reduce these effects, there is need to have an understanding on the minimum threshold levels for all the factors of flashing lights that affects the people with epilepsy. Generally, there is need to use TFT screens with a frequency of at 100 Hz and stay at least 2.5 meters away from the flashing light in a well-lit environment (Harding & Harding, 2010).

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 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.)
This paper is going to discuss the condition Epilepsy. Epilepsy is defined as a disorder of the brain characterized by the recurrence of unprovoked seizures (Shorvon, 2009). Epilepsy starts in your brain, the brain is like a computer, it is made up of a mass of cells, called neurons, which connect to each other in very complicated ways (Routh, 2004). Electrical messages are constantly being passed from one neuron to another down nerves to the muscles in the body (Mair, 2004). If a person has epilepsy, these cells sometimes send a sudden, unexpected burst of electrical impulses, which causes a seizure (Routh, 2004). When the seizure finishes the brain behaves normally again. For some people with epilepsy these seizures happen every day. For others they may happen only once or twice a year (Routh, 2004). There are over 40 different types of seizure and each person is slightly different, but there are a few common types (Routh, 2004). Generalized seizures which affect the whole brain and partial seizures which affect a small part of the brain (Miller, 2013). The most common types of ge...

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
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 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.
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.
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
The diagnosis of epilepsy is usually made after the patient experiences a second unprovoked seizure (Leppik, 2002). Diagnosis is often difficult, however, since it is unlikely that the physician will actually see the patient experience and epileptic seizure, and therefore must rely heavily on patient’s history. An electroencephalography (EEG) is often used to examine the patient’s brain waves, and some forms of epilepsy can be revealed by a characteristic disturbance in electrical frequency (Bassick, 1993). The variations in frequency can take form as spikes or sharp waves (Fisher, 1995). The variations are divided into two groups, ictal electrograph abnormalities, which are disturbances resulting from seizure activity, and interictal electrograph abnormalities, or disturbances between seizures. The EEG can also give clues as to which region of the brain the disturbances arise from. Interictal temporal spikes will predict the side of seizure origin in 95% of patients if three times as ...
As well as knowing your response time it is also important to know the safe following distance. A safe following distance is about two whole cars. But, when going different speeds it can vary. If you are just driving through Bronxville or any other small village where the speed limit is about 30 then it is ok to be about one car length away. This is a safe position because the spe...
A Hemingway Code Hero is a trait that almost every main character of Ernest Hemingway’s novels possesses. According to Hemingway, a Code Hero is a man (or woman) who lives correctly and demonstrates respect for honor and courage during a chaotic and stressful world. There is a particular pattern to how a Code Hero conducts his or her life on a day to day basis. In the novel A Farewell to Arms, Frederic Henry is the Code Hero because fate is a determining role in his life’s events, he lives in the here and now, and he shows grace under pressure.
