Parkinson’s Disease
1. Parkinson’s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine (多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson’s, these nerve cells Break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.
2. No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson’s disease in some people. But so far, there is not enough proof to show that it is always inherited.
3. Tremor (颤抖) may be the first symptom you notice. It is

Scientists studying Parkinson’s disease (PD) previously have (27) on the brain’s motor and premotor cortex, but not the somatosensory or the visual cortex. But Emory neurologist Krish Sathian, MD, PhD, and (28) had earlier discovered, through tests of tactile ability, that PD patients have sensory problems with touch. They designed a study using FMRI to investigate the brain changes (29) these sensory abnormalities.
Dr. Sathian’s research group studied six patients with (30) advanced PD and six age-matched healthy controls. After documenting the (31) movement problems of PD and ruling out dementia and nerve problems in the PD patients, they (32) a common test of tactile ability to both groups
