How Brain Pacemakers Treat Parkinson's Disease

the_newsbeagle writes Pharmaceutical research for neuropsychiatric disorders hasn't produced many breakthroughs lately, which may explain why there's so much excitement around "electroceutical" research. That buzzy new field encompasses deep brain stimulation (DBS), in which an implanted stimulator sends little jolts through the neural tissue. DBS has become an accepted therapy for Parkinson's and other motor disorders, even though researchers haven't really understood how it works. Now, new research may have found the mechanism of action in Parkinson's patients: The stimulation reduces an exaggerated synchronization of neuron activity in the motor cortex.

No new treatments?

What, you mean like this Parkinson's treatment just approved in January?

I've seen patients with it and without it and it's a stunning difference.

Parkinsons is worse having had experience of both in close family members. For the most part Alzheimer's sufferers are in themselves fairly unaware or unconcerned with their disease. Parkinsons the individual is usually fully aware of the disease and what they can no longer do for themselves, what they can't recall and what they have lost causing additional stress to both the sufferer and their family, along with depression and related mental health issues. Also the commonly perceived symptoms (shakes and immobility) in Parkinsons are not the only symptoms and there can often be significant (bad) personality changes that can break entire families apart.

My dad was one of the first in the area to have the implant and it worked well initially and gave my Dad 3 years of reduced symptoms while it was effective. Turning the implant on and off was literally like a switch on his tremor. Unfortunately there were complications with the placement of the probe (which was still "experimental" when it was done and we all knew the risks) that resulted in "mild" brain damage, him requiring full time professional care after 5 years and ultimately accelerated the progression of symptoms.

As for the "new" treatment this is just a new way to administer more or less the same concoction of drugs my Dad was on five years ago but back then was an endless array of tablets that all had different schedules of administration which is not easy for someone with advanced Parkinsons to manage...
