Question 1 of 5
A nurse is reviewing a client's MRI results that show cortical thinning. The nurse should identify that this finding is evident in which of the following types of dementia?
Correct Answer: B
Rationale: The correct answer is B: Alzheimer's disease. Cortical thinning is a characteristic feature of Alzheimer's disease due to the gradual loss of neurons and synapses in the cerebral cortex. This leads to a reduction in cortical volume, resulting in cortical thinning as seen on MRI.
Choice A, HIV infection, typically presents with other neurological findings like white matter abnormalities rather than cortical thinning.
Choice C, Prion disease, usually manifests with spongiform changes in the brain rather than cortical thinning.
Choice D, Substance use disorder, does not typically cause cortical thinning but may lead to other brain structural changes.
