The requirement for safety and efficacy can be frustrating, especially for badly needed treatments that are very promising, but such caution is necessary. One organization is trying to raise funds for a major study to test a pill for paralysis-4 amino pyridine (4 AP) -which has shown promising results in preliminary human trials (14). About half of the small number of people in the study, who had been paralyzed for four to fifteen years, regained some sensation and muscle function when they were given intravenous infusions of 4 AP.
The damage in a transmural MI will generally extend much deeper into the muscle tissue (Heuther and McCance, 2012). In the event of a myocardial infarction, there is an extreme inflammatory response once the heart begins to repair itself. The necrotic tissue is broken down by enzymes and transported to other parts of the body to be disposed of (Heuther and McCance, 2012). The scar tissue that initially replaces the necrotic tissue is weak and, as a result, it will take the patient a few weeks until they feel as if they can return to low levels of activity. After about six weeks, the necrotic tissue has been completely replaced by scar tissue.
Strokes were originally called apoplexy, which was just a general term for anyone suffering from a sudden case of paralysis. However, a doctor named Johann Wepfer discovered the bleeding in the brain of those stricken by apoplexy. He also was the first to suggest that the blocking of arteries to and within the brain could also be a cause of such disease. But it was only in the last few decades that the pr... ... middle of paper ... ... Strokes affect the entire world, whether it be from having to directly deal with the effects of the stroke or having to take care of an afflicted family member. This is a deadly disease that can strike suddenly and without much warning, but if the warning symptoms are known and the afflicted receives the right treatment on time than they have a high chance of being able to recover partially or even fully.
Stroke Stroke is a commonly known disease that is often fatal. This cellular disease occurs when blood flow to the brain is interrupted by either a blood clot halting the progress of blood cells in an artery, called an Ischemic stroke, or a blood vessel in the brain bursting or leaking causing internal bleeding in the brain, called a hemorrhagic stroke. When this happens, brain cells are deprived of oxygen and nutrients because the blood cells carrying these essential things are stopped, causing them to die. When the cells in the brain die, sensation or movement in a limb might be cut off and may limit an organism’s abilities. A person with stroke is affected depending on where in the brain the stroke occurs.
All of these characteristics, of the disease are caused by "degeneration of a group of nerve cells deep within the center of the brain in an area called the substantia nigra" (5). Dopamine is the neurotransmitter for these cells to signal other nerve cells. However as the cluster of nerve cells fail to operate, the dopamine can not reach the areas of the brain that affects one's motor functions (5). On average Parkinson's patients have "less than half as much dopamine in their systems as healthy people do" (8). The problem and controversy that arises from this disease is in the cure.

About ten to fifteen years following the first onset of symptoms the sufferer must be placed under care because they cannot even carry out the most basic of functions due to loss of movement (Wyndbrant, 174). Huntington’s Chorea is one of the most destructive and heart wrenching diseases facing people today. With the improved testing and the availability of pre-symptomatic results, plus drugs that can be used to alleviate pain and symptoms, the sufferers of this devastating disease have a brighter future and a eventual cure to look forward to.

HD was first described by Charles Walters. He and various other scientists were able to find proof that the disease was hereditary and its neurodegenerative effects. George Huntington was the first person to thoroughly describe the disease and its hereditary nature. Originally called Huntington’s chorea, the name was changed to Huntington’s disease due to the fact that not all patients developed chorea and the other symptoms were considered more serious. HD is a disease that slowly deteriorates the brain’s neurons.
There has been some unsuccessful treatment trials like the use of methylprednisolone, but it demonstrated a failure in treating the case as well as using hypothermia therapy. (Wikipedia 2009 online). However, a potential treatment has been found; stem cell transplant. Its aim is to lessen the paralysis and regenerate nerve fibers since nerve cells are not replaced when damaged. Stem cells are taken from excess embryos of in vitro fertilization.
Rabies is a disease that requires fast treatment. Go too slow and all you can do is wait until death comes; painfully and tormenting you until you draw your last breath. Most often the cause of contamination is through the bite of a rabid animal. The virus then spreads through the nerves until it reaches the central nervous system (CNS) which is the spinal cord and the brain. Then the virus incubates in the infected creature’s body for approximately 3-12 weeks.
Multiple sclerosis symptoms are similar to those of a pinched nerve and transverse myelitis; which is caused by inflammation within the spinal cord. Normally multiple sclerosis’ course is different in everyone. Once the first attack has occurred, it may take days, weeks, months, or even years pass before the second attack can happen. Normally after relapsing remitting course, individuals will continue this phase and be considered in the secondary progressive course. After the age of 40 one can experience primary progressive multiple sclerosis, in which they will gradually experience a physical decline and sometimes show no remissions with temporary relief of any symptoms that are showing.
