What about surgeries for Parkinson's disease?
Surgery for Parkinson's disease is only recommended when all other treatments have failed. Procedures such as pallidotomy, thalamotomy, deep-brain stimulation, and transplantation can be performed stereotactically to target specific
ganglia for destruction or stimulation.
Pallidotomy is a surgical procedure that may restore normal brain activity related to voluntary movement in some patients. It is not a cure, however, and its primary benefit is to allow people to continue on medications without incurring some of the side effects. Pallidotomy involves destroying part of a small structure within the brain called the globus pallidus internus. The globus pallidus internus is a portion of the brain that affects movement, so this surgery may reduce tremors, but have negative side effects on balance and coordination.
Procedures called neurostimulation, also called deep brain stimulation, use electric pulse generators to control symptoms. They are proving to be safe and effective alternatives to surgery. Appropriate candidates are similar to those for surgery. (Patients being given neurostimulation, however, should not have pacemakers.) Like pallidotomy and thalamotomy, neurostimulation is not a cure; on the other hand, it does not remove brain tissue and is reversible. A surgeon implants an electrode in the area of the brain where nerve impulses are relayed and movement is generated. A wire from the electrode follows a path under the skin from the skull to a small generator implanted in the chest. The patient turns on the generator with a hand-held magnet to deliver an electronic pulse to the brain, which blocks the brain signals that trigger tremor. This treatment is not effective for everyone, so it is important to discuss this option thoroughly with your doctor.
Stem cell transplantation, in which fetal tissue is implanted in a patient's brain to replace malfunctioning nerves, is an ongoing source of controversial research but has shown some promise in treating conditions such as Parkinson's disease. Some patients also find relief from alternative treatments such as acupuncture, massage, and yoga. Botulinum toxin A is an alternative treatment that has been found effective in treating head, hand, and voice tremors. Botulinum is a bacterium that causes food poisoning (botulism), but causes the muscles to relax when used in a weak solution.Consult with your doctor before trying any alternative treatments such as botulinum toxin, vitamin therapy, or herbal therapy, because they can have adverse side effects or interfere with the action of levodopa.
More information on Parkinson's disease
What is Parkinson's disease? - Parkinson's disease is a progressive and degenerative movement disorder with primary motor symptoms. Parkinson's disease results from degeneration of dopamine-releasing neurons of the substantia nigra.
What causes Parkinson's disease? - The immediate cause of Parkinson's disease is degeneration of brain cells in the area known as the substantia nigra, one of the movement control centers of the brain.
Who're the risk factors for Parkinson's disease? - Age is one of the main risk factors for Parkinson's disease. Reduced estrogen levels may increase the risk of Parkinson's disease.
What're the complications of Parkinson's disease? - Dementia is the common complication of elderly Parkinson patient. Parkinson's disease poses a triple threat on the emotional health of its victims.
What're the stages Parkinson's disease? - Parkinson's disease may also be described by five stages: stage I (mild or early disease), stage II, stage III (moderate disease)...
What're the early symptoms of Parkinson's disease? - Early symptoms may include slight tremor or stiffness, a reduced sense of smell, a tendency to reduce body movements, difficulty walking.
What're the symptoms of Parkinson's disease? - Symptoms of Parkinson's disease include tremor, muscle stiffness, abdominal cramps, rapid speech with little expression in the voice, problems with sleeping.
How is Parkinson's disease diagnosed? - Diagnosis of Parkinson's disease is based on symptoms. There is no specific diagnostic procedure or laboratory test to establish the diagnosis of Parkinson's disease.
What're the treatments for Parkinson's disease? - There is no cure for Parkinson's disease. The treatment of Parkinson's disease mainly relies on replacing dopamine with levodopa.
What medications cure Parkinson's disease? - Drugs currently used to treat Parkinson's disease make movement easier and can prolong function for many years. The pharmacological treatment of Parkinson's disease is complex.
What about surgeries for Parkinson's disease? - Surgery for Parkinson's disease include pallidotomy, thalamotomy, deep-brain stimulation, and transplantation.
What about physical therapy for Parkinson's disease? - Following a program of regular exercise can help people with Parkinson's disease maintain mobility. Physical therapy can help Parkinson's disease patient.
What is l-dopa (levodopa)? - Levodopa, or L-dopa, which is converted to dopamine in the brain, remains the gold standard for treating Parkinson's disease.
