DBS on Parkinson’s Disease • By: Christopher Ross DeSanto • BME 181 / February 11, 2010
Parkinson’s Disease • Neuro-degenerative Disorder • Dopamine Deficiency • Causes emotional and physical complications • Affects Substantia Nigra
Parkinson’s of Physiology
No cure for Parkinson’s • Most Parkinson’s patients are on a drug regimen • Parkinson’s Disease medication target symptoms only • No medication ensures life-long stability • Most common drug today is Levodopa
Levodopa is converted into dopamine • Does not produce dopamine receptive cells • Does not stimulate cells to take in dopamine • DBS is an alternative to Levodopa
What is DBS? • A Deep Brain Stimulator is a device called a brain pace maker that is implanted into the brain. • Connected to an IPG (implanted pulse generator) • Sends electric pulses to the brain that stimulate dopamine production • Placed on the VIM of the brain
DBS • A reversible procedure • Requires skull penetration • Nodes placed directly on brain (lead) • Lead carries the charge
Statistics • 80% of patients experience little to no tremors after DBS use • For some patients medication is still needed but for all it reduces dosage needed • DBS has been reported to work for 4 to 6 years. • Everyone responds differently • Known to cause loss of feeling in face or limbs
Cures for Parkinson’s began in 1909 • Involved dangerous lesions to the brain (lobotomies) • 1947 created Stereo- encephalotome • Placed electric nodes over VIM section of brain • VIM still utilized today against Parkinson’s with DBS
Modern Applications of DBS • New technology being made yearly • Recently: RLS treatments • Sleep Disorder cure • Significant data has been found that it works better with those acute/ severe symptoms
