Illain-barrã© strikes some people and not others or what sets the disease in motion. What scientists do know is that the body's immune system begins to attack the body itself, causing what is known as an autoimmune disease. Guillain-barrã© is called a syndrome rather than a disease because it is not clear that a specific disease-causing agent is involved. viagra generic Reflexes such as knee jerks are usually lost. Because the signals traveling along the nerve are slower, a nerve conduction velocity (ncv) test can give a doctor clues to aid the diagnosis. safety of buying viagra online The cerebrospinal fluid that bathes the spinal cord and brain contains more protein than usual, so a physician may decide to perform a spinal tap. viagra reviews forum Treatment there is no known cure for guillain-barrã© syndrome, but therapies can lessen the severity of the illness and accelerate the recovery in most patients. buy viagra zimbabwe There are also a number of ways to treat the complications of the disease. Currently, plasmapheresis (also known as plasma exchange) and high-dose immunoglobulin therapy are used. generic viagra without prescription Plasmapheresis seems to reduce the severity and duration of the guillain-barrã© episode. In high-dose immunoglobulin therapy, doctors give intravenous injections of the proteins that in small quantities, the immune system uses naturally to attack invading organism. Investigators have found that giving high doses of these immunoglobulins, derived from a pool of thousands of normal donors, to guillain-barrã© patients can lessen the immune attack on the nervous system. viagra samples The most critical part of the treatment for this syndrome consists of keeping the patient's body functioning during recovery of the nervous system. This can sometimes require placing the patient on a ventilator, a heart monitor, or other machines that assist body function. Prognosis guillain-barrã© syndrome can be a devastating disorder because of its sudden and unexpected onset. Most people reach the stage of greatest weakness within the first 2 weeks after symptoms appear, and by the third week of the illness 90 percent of all patients are at their weakest. viagra no prescription The recovery period may be as little as a few weeks or as long as a few years. About 30 percent of those with guillain-barrã© still have a residual weakness after 3 years. About 3 percent may suffer a relapse of muscle weakness and tingling sensations many years after the initial attack. buy generic viagra Research scientists are concentrating on finding new treatments and refining existing ones. viagra results before after Scientists are also looking at the workings of the immune system to find which cells are responsible for beginning and carrying out the attack on the nervous system. The fact that so many cases of guillain-barrã© begin after a viral or bacterial infection suggests that certain characteristics of some viruses and bacteria may activate the immune system inappropriately. viagra buying online Investigators are searching for thos. generic viagra online
