BIO152H5 Lecture Notes - Lecture 17: Deep Brain Stimulation, Neurological Disorder, Neuron
Document Summary
Imagine if someone broke into your house at night, held you down so you couldn"t move, didn"t let you speak properly, and didn"t let you go to the bathroom. Parkinson"s is a neurologic disease that robs control of a person"s movement. It sends electrical signals to specific targets in the brain: deep brain stimulation has many pros such as improving motor symptoms (ex. tremors, slow walking). In a study conducted where deep brain stimulation was done on 13. Parkinson"s patients and 10 controls, the results showed that all patients had improved motor symptoms. Another pro is that it controls side effects of other medications taken for the disease, and the process doesn"t harm brain tissue: however, the process also has many cons such as not affecting sensory symptoms (ex. Pain, visual dysfunction) which are a major part of parkinson"s. Parkinson"s patients and 10 controls where deep brain stimulation was conducted, sensory symptoms remained the same after the surgery.
