Chapter 43: Problem 12

Amyloid associated with cerebral blood vessels is called: a. Argyrophilic Alzheimer vasculature b. Congophilic amyloid angiopathy c. Senile plaques d. Neurofibrillary tangles e. All of the above

Short Answer

Expert verified

Answer: Congophilic amyloid angiopathy.

Step by step solution

Understand the terms used in the question

The given question is about amyloid, which are proteins that can form abnormal deposits in the brain, associated with cerebral blood vessels. In order to determine the correct option, it is crucial to know the definitions of each term provided in the answer choices.

Define Argyrophilic Alzheimer vasculature

Argyrophilic Alzheimer vasculature refers to the blood vessels in the brain that accumulate silver-loving (argyrophilic) proteins. However, this term does not specifically indicate the presence of amyloids in the cerebral blood vessels.

Define Congophilic amyloid angiopathy

Congophilic amyloid angiopathy (CAA) is a condition in which amyloid proteins (congophilic proteins) are associated with cerebral blood vessels. This leads to weak vessel walls and can result in bleeding within the brain or an increased risk of strokes.

Define Senile plaques

Senile plaques are extracellular deposits of amyloid proteins in the brain, commonly found in patients with Alzheimer's disease. They do not refer specifically to amyloid proteins associated with cerebral blood vessels, but rather refer to amyloid deposits in the brain tissue.

Define Neurofibrillary tangles

Neurofibrillary tangles are intracellular accumulations of proteins (tau) in the brain that occur in Alzheimer's disease. They do not specifically involve amyloid proteins or their association with cerebral blood vessels.

Consider option (e)

Option (e) suggests that all of the above options are correct. However, as we have already seen, the other options do not specifically involve amyloid proteins associated with cerebral blood vessels.

Conclusion

After analyzing the given options, it becomes clear that the correct answer is (b) Congophilic amyloid angiopathy, as it is the only term that specifically refers to amyloid proteins associated with cerebral blood vessels.
