Scientists were considering whether it is possible to help patients suffering from Parkinson's disease by using a procedure called deep brain stimulation. In a recent research, scientists from Oregon Health and Science University have found out two specific areas of brain, where the procedure of deep brain stimulation may be used.
The treatment for Parkinson's consists of the drug levodopa, although tests on newer drugs are also going on. However, after prolonged use, the effect of the drug levodopa does not remain that strong. Then using the stimulation of brain regions of the globus pallidus interna and the subthalamic nucleus, any one at a time, can give the adequate help to maintain motor function.
The procedure of deep brain stimulation consists of multi-electrode lead, which is implanted in the specific area of the brain. The lead is connected to a pulse generator embedded in the chest. The generator produces a high frequency electric current that is conducted by the electrode to the brain. This blocks the tremors.
Researchers are of the opinion that stimulation in either of regions specified helps the patients suffering from Parkinson's when medications do not have much effect.
