Module 6 Case Study

Question 1

Donna, a 42-year-old mother of two, has been experiencing intermittent tingling and numbness in both of her feet. She has also had trouble holding a pen while writing. In the past few months, the tingling and numbness in her extremities seemed to subside on its own, so she was not very concerned. Recently, though, the symptoms have spread to her knees and thighs and are persisting.

Yesterday, she stumbled when getting out of bed in the morning. When she tried to stand, her right leg was too weak to hold her weight and she fell again. She noticed that she scraped her right knee during the fall, but does not feel any pain from the wound. Donna notices that she has blurry vision and thinks that might be the reason she fell.

All of the following indicate sensory deficits EXCEPT:

Question 2

Donna does not feel the wound on her knee. In a normal situation, describe how this sensory input of a scraped knee would result in the feeling of pain.

Question 3

Donna has weakness in her right leg, but her left leg is functioning normally. Which components of the nervous system are involved with skeletal muscle movement? Be specific about how the motor impulse moves through the body.

Question 4

Which of the following correctly defines a motor unit?

Question 5

Which of the following statements is true?

Question 6

List and describe any and all symptoms in Donna’s history that could be related to a pathology of her motor neurons.

Question 7

Donna’s primary care physician wants to screen her for Multiple Sclerosis. Which of the following tests would provide the most definitive diagnosis for MS?

Question 8

If Donna does have MS, the disease is affecting her myelin sheath. Briefly describe what happens to the myelin sheath and how it disrupts nerve function in patients with Multiple Sclerosis.

Question 9

Donna later sees a specialist who wants to perform a spinal tap, which is an analysis of cerebrospinal fluid. Where is cerebrospinal fluid (CSF) found?

Question 10

After extensive testing, Donna’s care team concluded that she does have Multiple Sclerosis and have prescribed steroid treatment. How will steroids help alleviate her symptoms?

Question 11

Andre is a 68-year-old grandfather who has been struggling with his memory lately. At first, he was simply forgetting an appointment from time to time or forgetting to take his morning vitamins. However, now his spouse and children have noticed that his forgetfulness is progressing. There have been moments where he forgot how to get home, couldn’t remember his own phone number, or the names of his grandchildren. His family is worried he may have Alzheimer’s disease and they are not sure what to do.

Andre’s family decides to do some research about dementia and

Alzheimer’s disease. Which of the following statements is true?

Question 12

Which of the following is NOT a typical symptom of Alzheimer’s disease?

Question 13

Which of the following scenarios is considered a normal age-related change in memory?

Question 14

What are the risk factors in Andre’s history that would support a diagnosis of Alzheimer’s disease?

Question 15

What other Alzheimer’s disease risk factors might exist that are not given in Andre’s history? List and describe at least 5 risk factors.

Question 16

As Alzheimer’s disease progresses, the brain produces less and less of which neurotransmitter?

Question 17

Alzheimer’s disease is diagnosed using all of the following tools EXCEPT:

Question 18

Describe how the plaques found in Alzheimer’s disease disrupt nerve impulses.

Question 19

There is no cure for Alzheimer’s disease, but cholinesterase inhibitors can be used to treat symptoms like memory loss or language issues. Briefly discuss how this type of medication affects the physiology of neurons and nerve impulses.

Question 20

Andre’s primary care physician will likely refer him to a specialist. Which type of specialist treats Alzheimer’s disease? With the information you are given about Andre, how do you think his specialist will proceed? List and describe at least 3 treatments, tests, or other options that would make sense for Andre’s stage of memory loss.
