H.M. was born in Hartford, Connecticut in 1926. H.M. had epilepsy, which ran through his family. Three of his cousins had epilepsy as well as his father’s side of the family. When he was nine, H.M. had a bicycle accident and he got a head injury from it. He soon began to get epileptic seizures from it, however, the origin of his epilepsy is still unknown. When H.M. was sixteen, he had his first major seizure. By the time H.M. was in his twenties, the severity and frequency of his seizures began to grow and get worse. He started having blackouts and seizures up to ten times a week. At the time H.M. was working as a motor winder, and…
Epilepsy is a common neurological disorder characterised by recurring seizures. Different types of epilepsy have different causes. Accurate estimates of incidence and prevalence are difficult to achieve because identifying people who may have epilepsy is difficult. Epilepsy has been estimated to affect between 362,000 and 415,000 people in England. In addition, there will be further individuals, estimated to be 5–30%, so amounting to up to another 124,500 people, who have been diagnosed with epilepsy, but in whom the diagnosis is incorrect. (NICE CG)…
The patients of the early 1940’s who underwent the split-brain surgery often did not experience any relief of their epilepsy and therefore surgeons had stopped performing this unworkable procedure. It was not until twenty years later that a complete commissurotomy (severing of connections of the hemispheres) was performed on a former Paratrooper who was experiencing life threatening seizures. (Francois et al, 2000). The doctors who performed the surgery, Phillip Vogel and Joseph Bogen felt the corpus callosum was a critical pathway for the spread of epileptic discharge from one hemisphere to the other (Francois et al, 2000). This took place in 1962 and was done by Vogel and Bogen, who successfully separated the two cerebral hemispheres, which was effective in stopping the patient’s seizures. The same procedure was also subsequently performed on a series of patients who suffered intractable epilepsy.…
People of all ages can get it and a significant sign of diagnosing the condition is experiencing two or more seizures in a 24 hour period (“The Epilepsies” 2016). Although there is no cure for epilepsy, the condition can be controlled with anticonvulsant drugs. I personally have prior knowledge of the condition from my AP Biology class. I immediately thought of my senior year of high school, when I first was taught about epilepsy. My friend Nadine showed us a documentary which showed an old man who would suddenly fall out of consciousness during his daily tasks; I remember this documentary very well because it was a scary sight for me to…

There are many causes of an ABI. Traumatic Brain injury is caused by physical traumas, for example an accident, neurosurgery, head injury or even an assault. Brain injury can also be caused by non traumatic circumstances such as a stroke, brain tumours, infections, hypoxia, ischemia or substance abuse. Brain damage caused by neurodegenerative disorders are not classed as an ABI. Injury is referred to as either open or closed. A closed injury is when the brain has been damaged from the brain being bounced around the head or severe shaking, for example when in a road traffic accident. Open brain injury is a lot less common than closed and is incurred when a foreign object enters the brain, usually fracturing the skull. An example of this is a bullet entering the brain. These injuries are usually more localised and result in specific damange to the brain. Although traumatic brain injury is classed as part of ABI, it is different as ABI takes place at a cellular level and can affect different zones within the brain. Traumatic Brain injury will only affect the area of the brain in which the trauma occured.…
According to the Center for Disease Control (CDC), a concussion is not a bruise to the brain caused by hitting a hard surface. No physical swelling or bleeding is usually seen on radiological scans. The injury generally occurs when the head either accelerates rapidly and then is stopped, or is spun rapidly. This violent shaking causes the brain cells to become depolarized and fire all their neurotransmitters at once in an unhealthy cascade, flooding the brain with chemicals and deadening certain receptors linked to learning and memory. The results often include confusion, blurred vision, memory loss, nausea and, sometimes, unconsciousness. Neurologists say once a person suffers a concussion, he is as much as four times more likely to sustain a second one. After several concussions, it takes less of a blow to cause the injury and requires more time to recover.…
Traumatic accidents can include road traffic collisions, physical assaults and falls can cause damage to the brain. For example, in a road traffic collision the brain moving around in the skull can cause damage to certain parts of the brain which results in an acquired brain injury.…
Heredity can play a role on the temporal lobes and the functions of the temporal lobes. One of the diseases that can affect the temporal lobes is temporal lobe epilepsy (TLE) consists of a heterogeneous group of seizure disorders originating in the temporal lobe. TLE had been thought to develop as a result of acquired structural problems in the temporal lobe (Su-Kyeong Hwang, 2011). Another disease that effects the temporal lobes is a disease called pick 's disease is a cause of dementia similar to Alzheimer 's disease. The disease affects the memory center of the person and will cause the…
There are two main types of brain injury. Traumatic Brain Injury (TBI) is caused by an external force such as a blow to the head that causes the brain to move inside the skull resulting in damage. An Acquired Brain Injury (ABI) occurs at the cellular level. These include degenerative diseases such as parkinsons, brain development problems such as autism, blood flow issues including stroke and infection by bacteria and viruses.…
Seizures happen when the brain cells send out abnormal signals. When people have recurrent seizures it called a seizure disorder also known as Epilepsy. There are two general types of seizures; partial seizures and generalized seizures.…
Traumatic brain injury, also called acquired brain injury or simply head injury, is a result of a sudden blow to the head when an external force is applied causing a disruption of the physiological stability of the brain locally. It can also occur when an object pierces the skull and enters the brain tissue and when elevation in the intracranial pressure occurs and potentially dramatic changes in the blood flow within and to the brain. These changes may produce a diminished or altered state of consciousness. Traumatic brain injury is a nondegenerative, noncongential defect in which there may be permanent or temporary impairments to cognition, physical, and psychosocial functions.…
