What are the symptoms of Parkinson’s disease?

In order to create your slideshow, review the two case studies and then answer the questions following each case study:

Case Study 1: Isaac is a fifty-nine-year-old man. Several months ago, he noticed a slight tremor in his hands. He assumed this to be a normal consequence of aging. The tremor, however, gradually worsened, along with some muscular stiffness and slowness in initiating movement. The tremor was more pronounced when he was not voluntarily moving. Isaac was referred to a neurologist, who diagnosed him with Parkinson’s disease. After visiting the neurologist, Isaac and his family ask you to further explain this disorder. Isaac also asks about L-dopa as a treatment—the neurologist had mentioned L-dopa as an effective medication but had instead prescribed selegiline:

  • What are the symptoms of Parkinson’s disease?
  • What are the possible causes? Be sure to discuss both hereditary and environmental factors thought to contribute to this disease.
  • What parts of the brain does this disease affect?
  • Why do you think the neurologist prescribed selegiline instead of L-dopa?

Case Study 2: Sabrina is a twenty-seven-year-old woman who recently underwent a corpus callosotomy. Initially after surgery, when given a verbal command, Sabrina demonstrated marked apraxia of the left hand. However, the extent of this issue diminished over time. Answer the following questions about this client:

  • What disorder was most likely being treated by this operation, and how is the surgery performed?
  • In what way is the surgery expected to help Sabrina?
  • What are the risks and benefits of the surgery? Compare these to the risks and benefits of an alternative treatment. If the decision were yours, which would you recommend? Explain your decision.
  • What was the cause of the apraxia?
  • What does the reduction in apraxia symptoms tell us about hemispheric specialization?
