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?
HIV infection
Alzheimer's disease
Prion disease
Substance use disorder
The Correct Answer is B
B In Alzheimer's disease, cortical thinning typically begins in the temporal and parietal lobes of the brain, areas associated with memory, language, and higher cognitive functions. As the disease progresses, cortical thinning may extend to other regions of the brain, contributing to the worsening cognitive decline seen in affected individuals.
A. HIV-associated neurocognitive disorders (HAND) can result in various structural and functional changes in the brain, including cortical atrophy, but cortical thinning is not a specific hallmark of HIV infection-related dementia.
C. Prion diseases can lead to spongiform changes and neuronal loss in the brain, but cortical thinning is not typically described as a characteristic feature.
D. Chronic substance abuse, particularly alcohol and certain drugs, can lead to structural and functional changes in the brain, including cortical atrophy. However, cortical thinning is not specific to substance use disorder-related dementia and can occur in various other neurological conditions as well.
