This type of MS is seen in only a small percentage of patient’s. Progressive, cumulative symptoms and deterioration occur over several years.” (Ignataviscius & Workman, 2013, p. 978) (Ignataviscius & Workman, 2013, p. 978) Etiology The exact cause of MS is unknown and is very complex. • Viruses are recognized as causes of demyelination and inflammation, making it possible that a virus or other infectious agent can trigger MS. Though no single virus has been identified as causing MS in a genetically predisposed person. (Ignataviscius & Workman, 2013, p. 979) • MS is often seen in colder climates of the northeastern, Great lakes and the specific northwestern states, making the environment a possible MS trigger.
The argument that all viruses are deadly is incorrect. In the Hot Zone, Preston explained how Ebola and Marburg caused an epidemic that killed over hundreds of people and animals. In the novel, Preston also mentions smallpox and malaria. Being diseases, there are cures for all of them which overtime will eventually prove to be not deadly. Although hundreds of lives were lost against the virus, there came a cure later on.
To this date Cholera is still a global problem and causes about 130.000 deaths every year. Another major outbreak was the 1918 Spanish flu, which was extremely contagious. 500 million people all around the world were infected and 50 to 100 million of them were killed, which was about 3-5% of the world’s population. What really accelerated the spread of the disease was the fact that for a long time reports about the outbreak were withheld from the public due to military reasons connected with World War I. Interestingly, the only country where newspapers reported on the flu was Spain, which was neutral. Therefore, the impression was created that this country was the only one affected.
Parkinson's is one of the neurodegenerative diseases and is the second most common neurodegenerative disease after Alzheimer’s 1. It is reported that in developed countries, nearly one out of 100 people older than 60 years old suffers from Parkinson disease 2. Parkinson is allegedly caused by the damage of brain nerve cells on the substantia nigra. This damage causes the decrease of dopamine in the brain which diminished the ability to regulate the movements, bodies, and emotions 3. The symptoms of the disease include progressive loss of muscle control, slowness of movements (bradykinesia), tremor, postural instability, or catalepsy.
During this latency, no viral particle is produced but the entire genome is expressed and some proteins are transcribed. It has been identified as transcript proteins in infected human ganglia the genes; orf21, orf29, orf62, orf63 and orf66. Specifically, ORF63p (IE63) is the most transcribed protein during latency in infected human ganglia. The development of zoster is usually observed in people over sixty years old or immunodeficient patients. Instead of varicella, which occurs in the spring, zoster has no seasonal predilection (Mueller et al.,
One of the most distinctive features of H.pylori is the genetic diversity between clinical isolates obtained from different patient populations. Most H. polyri isolates can be discriminated from others by DNA profiling or sequencing of corresponding genes due to mainly a high degree of sequence divergence between orthologs (3-5%).H.Pylori infestation is followed by continuous gastric inflammation in virtually all individuals. Worldwide, H.pylori-induced gastritis
Malaria is the most common disease in third world countries with a tropical climate; the disease is caused by a parasite called Plasmodium, which is transmitted through the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Symptoms of malaria include fever, headache, and vomiting, and usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. In many parts of the world, the parasites have developed resistance to a number of malaria medicines.
Age Group: 65-75 Environment: Home Alzheimer’s Disease is a progressive disease, meaning memory loss is mild in the beginning, but it worsens over time to the extent that individuals are unable to have conversations or respond to their surroundings. A group of brain disorders that causes the loss of intellectual and social skills brain cells degenerate and die causing a steady decline in the memory and mental function. The likelihood of having Alzheimer’s increases tremendously after the age of 70. There are no genetic risk factors and Alzheimer’s disease is more prevalent in African Americans and Hispanics. Some of the problems of this disease is: Memory lapses ADL’s Medication management Social participation Inability to remember recent
Introduction Cerebral palsy is a life-long static physical disability that doesn’t worsen, nor get better over time. Cerebral palsy is an umbrella term that covers a few different types of CP. Cerebral palsy has many great affects on one’s physical development such as muscle tone, movement, coordination, control, balance, gross/fine motor functions and oral motor functions in ways to make a person’s life more difficult. Causes Of Cerebral Palsy Cerebral palsy is caused by damage to the brain either before, during or shortly after birth. About 70% of cerebral palsy cases are caused by prenatal injuries, and is the most common lead to CP.
