What is the treatment for Parkinson's disease?
There is currently no treatment to cure Parkinson's disease. Several
therapies are available to delay the onset of motor symptoms and to ameliorate
motor symptoms. All of these therapies are designed to increase the amount of
dopamine in the brain either by replacing dopamine, mimicking dopamine, or
prolonging the effect of dopamine by inhibiting its breakdown. Studies have
shown that early therapy in the non-motor stage can delay the onset of motor
symptoms, thereby extending quality of life.
The most effective therapy for Parkinson's disease is levodopa (Sinemet), which is
converted to dopamine in the brain. However, because long-term treatment with
levodopa can lead to unpleasant side effects (a shortened response to each dose,
painful cramps, and involuntary movements), its use is often delayed until motor
impairment is more severe. Levodopa is frequently prescribed together with
carbidopa (Sinemet), which prevents levodopa from being broken down before it reaches the
brain. Co-treatment with carbidopa allows for a lower levodopa dose, thereby
reducing side effects.
In earlier stages of Parkinson's disease, substances that mimic the action of
dopamine (dopamine agonists), and substances that reduce the breakdown of
dopamine (monoamine oxidase type B (MAO-B) inhibitors) can be very efficacious
in relieving motor symptoms. Unpleasant side effects of these preparations are
quite common, including swelling caused by fluid accumulation in body tissues,
drowsiness, constipation, dizziness, hallucinations, and nausea.
For some individuals with advanced, virtually unmanageable motor symptoms,
surgery may be an option. In deep brain stimulation (DBS), the surgeon implants
electrodes to stimulate areas of the brain involved in movement. In another type
of surgery, specific areas in the brain that cause Parkinson's symptoms are
An alternative approach that has been explored is the use of
dopamine-producing cells derived from stem cells. While stem cell therapy has
great potential, more research is required before such cells can become of
therapeutic value in the treatment of Parkinson's disease.
In addition to medication and surgery, general lifestyle changes (rest and
exercise), physical therapy, occupational therapy, and speech therapy may be
