What disorder was most likely being treated by this operation, and how is the surgery performed?
By the due date assigned, submit your response to the appropriate Discussion Area. Use the same Discussion Area to comment on your classmates’ submissions through the end of the module.
The following website contains links to research projects on treatment for drug abuse currently being funded by the National Institute on Drug Abuse. Browse the various studies underway and choose a clinical trial that assesses a potential treatment.
- Summarize the study for your classmates.
- Explain whether this treatment would be characterized as a behavioral intervention or a drug/pharmacological intervention.
- Explain how this intervention relates to any of the drug treatments you read about this module.
- Identify the physiological changes this treatment might bring about. For example, will a particular neurochemical be altered by this drug or behavior?By the due date assigned, create a Microsoft PowerPoint presentation to educate a group of medical students participating in their grand rounds. There should be at least ten slides in your Microsoft PowerPoint as well as a title slide and a slide listing all your sources for creating this slideshow. You should also create speaker notes for each slide of your presentation, which include the main talking points for the topic addressed on the slide. Save the presentation as AU_PSY350_M3_A2_LastName_FirstInitial.ppt. Submit your assignment to the Submissions Area.
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?
