Drugs and other treatment options
There is currently no cure for Parkinson’s disease. There are, however, very effective medicated treatment options (tablets, pump) as well as surgical options (deep brain stimulation) in order to reduce the motor symptoms. These methods reduce trembling and stiffness and thereby ameliorate the patient’s walking and general movements. So far, none of the commonly used medication or pacemaker systems have shown scientific evidence of slowing down or stopping disease progression.
The anti-parkinsonian drugs merely replace the loss of dopamine in the brain. As dopamine itself can’t cross the blood-brain barrier, the patient is given the prodrug L-DOPA that is then metabolised to dopamine in the brain. Other drugs include dopamine agonists; these are compounds that imitate the effect of dopamine in the brain.
Unfortunately, the effect of these treatment options diminishes over time due to the natural disease progression. Moreover, these drugs have side effects such as nausea, unintentional movement (dyskinesia), hallucinations, tiredness and compulsive behaviour. It is, therefore, important that the neurologist regularly monitors the patient.
Under certain circumstances, some patients can be treated with deep brain stimulation. This brain pacemaker consists of electrodes, that are placed in regions in the midbrain, where loss of dopamine occurs (mostly in the Nucleus subthalamicus). The electrodes are stimulated through a device that is positioned near the clavicle. This brain pacemaker does not cure the disease but allows the medication to be substantially reduced and improve the motor symptoms.
