Damage to the temporal lobes caused the brain from registering any new events that had happened. The frontal lobe is involved in motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, and social and sexual behavior, Greg was unable to carry on a normal conversation and was found to not make sense of what was trying to be communicated. Greg’s hypothalamus was also destroyed, and explains the reason for his blindness (Carpenter & Huffman, 2011). This case study led to scientific knowledge of how that specific brain regions function by Doctors and physiologists being able to study Greg and use the findings to share with other people in the science community. Oliver Sacks discovered, even though Greg lost a great portion of his brain, that when music played Greg would become more alive, more engaged in life, especially when music like the Grateful Dead or other music from that era would be played (Sacks, 2011).
It is a physical condition affecting the brain. It can be caused by various things such as age, down syndrome and genetics. It is caused when abnormal clumps called either plaques or tangles interfere with how the brain cells work and communicate which cause them to die. People with Alzheimer’s also have a shortage of chemicals that help with the transmission of the brain. The symptoms of Alzheimer’s disease may change as the disease progresses.
Other frequently encountered challenges include phantom-limb pain; pain within the residual limb; additional pain symptoms affecting the neck, shoulders, back, and sound-side limb; overuse syndromes; elevated anxiety rates and depression; and a compromised quality of life. The thought of losing an anatomical part, is devastating to most people. When it happens, amputation causes a threefold loss in terms of function, sensation and body image. The amputee is no different than any other human being that is confronted with a crisis situation, in that he must adapt rather than succumb to the handicapping condition. Difficulties encountered are often due to misperceptions of what life for an individual labelled "amputee" is actually like, and consequently, great problems in rehabilitation result.
Autism is a disease that affects information processing in the brain by altering how nerve cells and their synapses make connections, or make logic. The most frustrating part about Autism is that we still do not know what causes this, or how to prevent it. This is a very serious mental disorder and it is also a very misunderstood disorder. People tend to associate autism with down syndrome and other mental disorders. Where in most cases the carrier of that disease isn't able to learn or retain information like a normal person could.
It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
Eventually, I landed in a hospital bed with an IV pumping a cocktail of drugs meant to cure "a series of infections" ravaging my body. When I finally felt reasonable enough to go to class, I couldn't remember things. My essays, as one professor told me, suddenly "read like ramblings." I wasn't me. That semester, I ended up taking incompletes in all of my classes.
An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically. A hemorrhagic stroke typically occurs when the blood vessel walls weaken over time, which leads to a bulge or rupture of the vessel. Aneurysm is the most common type of hemorrhagic strokes with a low survival rate. They also kill brain cells, which can never regenerate. The affect of strokes on the body can range between mild dizziness or slight numbness to impaired speech and loss of motor control.
According to the article "What Is Combat PTSD?”, Diagnosing Post Traumatic Stress Disorder can be hard because soldiers view reporting their symptoms as a sign of weakness (What, 1). This makes it difficult to get an accurate idea of exactly how many men and women return from war with Post Traumatic Stress Disorder. Those who suffer from Post-Traumatic Stress Disorder often relive the horrendous events they have experienced in combat. Behaviors of this disorder can take on many forms. Sufferers may have a hard time relaxing, experience anxiety, and they often battle depression.
In addition to this, the connections between affected nerve cells deteriorate. As the disease progresses, it spreads and affects cells in other parts of the brain. Day to day memory problems are first noticed but other symptoms include not knowing the right words anymore, problem solving, decision making or 3 dimensional perception. * Vascular dementia is caused when the brain is deprived of oxygen. This happens when the arteries which carry oxygenated blood to the brain can't get there and the brain, or part of it, dies.
Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size. As a result, behavior, memory and thinking are affected. Vascular dementia is caused by blockages and breaches in the brain's blood supply that damage the brain and can be caused by any condition which results in an interruption to the blood flow to the brain, and as well as strokes, this could include diseased arteries, heart attacks, high blood pressure, raised cholesterol, diabetes, furred arteries and irregular heart rhythms. Any condition causing damage to the circulation of blood to the brain carries a risk to mental functioning. People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving.
