Tuesday, researchers revealed that deep brain stimulation significantly improved Parkinson’s disease symptoms including trembling and slowness of movement, which raises high hopes for all those suffering from the incurable condition.

Moreover, they said that six months of deep brain stimulation with a device made by Minneapolis-based Medtronic Incorporated improved the Parkinson’s patients’ quality of life and gave them 4 and a half hours more per day of properly functioning motor skills.

Nevertheless, the risks are not to be taken lightly, researchers added.

Medtronic’s small electrical device has to be surgically implanted in a patient’s chest, along with wires traveling to the brain’s electrodes, in order for the device to send electrical impulses to the areas in the brain that control movement.

The study looked at 121 Parkison’s patients who received deep brain stimulation (DBS), one of whom died from bleeding in the brain that was caused by a ruptured blood vessel as an aftermath of the surgery.

Furthermore, researchers revealed that compared to the control group, comprising 134 patients who underwent standard medical treatment for their condition, the DBS group ones were 3.8 times more prone to develop a post-surgical infection or other adverse events.

Still, 71 percent of the patients who had had deep brain stimulation registered motor skills improvement, while their quality of life also went up, since they were rendered able to perform daily activities, which resulted in emotional well-being.

The study was published in the Journal of the American Medical Association.
