It is just as deep brain stimulation are at great risk, such as infection, due to the complexity of surgery to be done. Once the results of a study published Tuesday in the medical journal the U.S. medical associations, the Journal of the American Medical Association.
''This is obviously brain surgery and it will cause everyone to stop for a moment,''said David Charles, MD from Vanderbilt University in Nashville, Tennessee. But the problem facing patients is generally associated with surgery, and many of them free from the effects of it after 6 months.
In the treatment with implantation of this system, electrodes are used to transmit electrical impulses to the substantia nigra, a sector within the crescent-shaped brain center, function to control and coordinate movement. In Parkinson's patients, the production of dopamine - a type of chemicals in the brain that control muscle movements required in the - in the brain cells, have degenerative, causing the muscles were shaking (tremors), seizures, slow and loss of coordination.
The use of drugs like levodopa are helping to reduce uncontrolled muscle movement and vibration. But for many people the use of the drug will soon lose its effectiveness with time, whereas the side effects - such as jerky movements, and vibration in the hands getting worse.
Introduced since the late 1990s, treatment with this grafting system, received widespread acceptance. But not many studies comparing it with a treatment system that is already known.
In the new study, a team led by Frances Weaver of Hines VA Hospital in Hines, Illinois, were randomized to treat 255 patients with Parkinson's transplant system or drug therapy, including physical therapy,. A quarter of the number of patients aged over 70 years.
After 6 months, patients were treated with graft system with excess 4.6 hours per day without interruption involuntary movements. Overall, 71 percent of patients with graft therapy showed improvement in motor function compared to only 32 percent of patients with drug therapy.
In the United States today there are 1 million people with Parkinson's, and growing every year with 50,000 new patients. Artist Michael J. Fox is the most popular figures who suffer from this disease, other than perhaps the biggest boxing former world champion Mohammad Ali.
