Huntington's Disease Research Paper
Huntington’s disease is a disease of the brain wherein a person’s capability to think, talk, and move is affected. The disease was first described by Dr. George Huntington in 1872. The actual gene was not characterized until 1993. In Huntington’s disease there is a mutation of a gene on chromosome 4. The protein (huntingtin) for the gene is responsible for directing the delivery of vesicles to the outer area of the cell. The normal coding for this gene is CAG repeated many times, the number of repeats vary by person (ranges 10-26). When a person has Huntington’s they develop an abnormally high number of these repeats, around 40 or more. This mutation can lead to accumulated clumps of huntingtin that can lead to cell death. Although scientists

Understanding Alzheimer's Disease
930 Words | 4 PagesAlzheimer 's is a disease that interferes with normal function of the brain related to memory and other important functions, and also deteriorates the brain. How exactly does the brain just deteriorate on itself? The answer to that question has to do with two things called plaques and tangles. Plaques are clumps of protein also referred as beta-amyloid that destroy brain cells in a couple different ways. One for examples is cell-to-cell communication, the process by sending and receiving signals between cells that initiate a certain reaction.
Neurobiology REU Personal Statement
392 Words | 2 PagesI have always been fascinated by the workings of the brain and the complexity of neurodegeneration. My interest in this field was deeply rooted in my personal experience when my grandmother was diagnosed with Alzheimer's disease. Watching her cognitive decline instilled in me a burning desire to understand this condition and find ways to restore her functioning. This curiosity has since transformed into a passion to research Alzheimer's disease and drive our current understanding of neurodegeneration. I have taken every opportunity to dive deeper into this multifaceted field.

Some symptoms of this disease are seen about 2-3 years in advance, giving doctors and indication that this patient at some time will be officially diagnosed with dementia. This accounts for extra brain power or
Parkinson's Disease Research Paper
791 Words | 4 PagesEssay 86: Parkinson's Disease and the 1918 Flu Pandemic Parkinson's disease (PD) is a degenerative motor disorder resulting from the progressive loss of dopaminergic neurons in an area of the brain known as the basal ganglia, in particular two clusters of cells called the substantia nigra. The manifestations of PD appear when 80% or more of the dopamine producing neurons have been destroyed. Symptoms of PD include difficulty initiating movement (bradykinesia); a shuffling gait; the classic pill rolling hand tremor; a blank facial expression; muscle rigidity; and in 10-15% of cases, the onset of dementia late in the course of the disease. Nearly a century ago, in the wake of the 1918 influenza pandemic, which left as many as 50 million
Creutzfeldt-Jakob's Disease Research Paper
930 Words | 4 PagesCreutzfeldt-Jakob’s Disease: Neuromuscular Disease Creutzfeldt-Jakob’s Disease (CJD) is a rare, degenerative, invariably fatal brain disorder, which is derived from transmissible spongiform encephalopathy caused by prions. Prions occur in a normal state, which are harmless proteins found in the body’s cells, and also in an infectious form that causes disease. Harmless forms of prion proteins have the same sequence of amino acids, but the infectious forms of protein have a different folded shape than normal proteins. Once the abnormal protein prion appears they aggregate together, giving the brain a spongy appearance, characterized by tiny holes. These infectious particles are mainly found on the surface of cells in the central nervous system.

Alois Alzheimer's Disease
806 Words | 4 PagesAlzheimer's was given its name in 1906 by a germen doctor who was the first to put a name to the disease, his name was Alois Alzheimer. Alzheimer's disease is a progressive neurodegenerative condition. It’s a disease that causes dementia, or loss of brain function like thinking and reasoning skills. It affects the parts of the brain that are important for memory and language. A person’s brain with Alzheimer's contains irregular clumps of cellular debris and protein called plaque along with collapsed microtubules.
Man Who Mistook His Wife
456 Words | 2 PagesIn his book, author Oliver Sacks tells the accounts of many of the stories he has encountered throughout his career as a neurologist. Each individual story ranging from a variety of different neurological disorders, displays a common theme which add to Sacks’ overall message conveyed. The themes that are conveyed by Sacks include losses, excesses, transports, and the world of the simple. Each theme consists of grouped stories that coincide with the overlying message. In the losses section, the nine chapters all deal with some sort of deficit inside of the brain.

Nerve Injury Research Paper
451 Words | 2 PagesNerve injuries around the shoulder region occur mainly as a result of motor vehicle accidents, gunshot injuries and athletic injuries. Contact sports athletes such as football players and wrestling athletes, are at high risk of nerve injury in the shoulder area, caused by an extreme force and stress applied on the joint. In this acute setting, these injuries may be associated with shoulder dislocation, upper humeral fracture, rotator cuff tear or/and vascular trauma, such as axillary artery rupture. Nevertheless, nerve injuries to the shoulder, can also be caused by overuse and chronic repetitive stress, often observed in sports involving repetitive overhead or throwing activities. A higher incidence in this type of injuries is marked in individuals that specialize at an

The Cause Of Alzheimer's Disease
829 Words | 4 PagesNeurons, which produce the brain chemical, acetylcholine, break connections with other nerve cells and ultimately die. “Two types of abnormal lesions clog the brains of patients with Alzheimer 's disease: Beta-amyloid plaques, sticky clumps of protein fragments and cellular material that form outside and around neurons, and neurofibrillary tangles, insoluble twisted fibers composed largely of the protein tau that build up inside nerve cells” (alzfdn.org). The cause for this is still unknown. Alzheimer’s disease is also the most common cause of dementia in people sixty-five years and older. Alzheimer’s is not a normal part of aging or dying, contrary to what some people may think.
