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

Answer and Explanation

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.

A. Medical insurance availability for substance use disorder treatment. B. The developing brain is exposed to substances at an early age. C. The brain already has cognitive deficits that causes it to be vulnerable to addiction. D. Initial use of substances began in adulthood.

Correct Answer is B

Explanation

B. Exposure to substances at a young age, especially during periods of brain development, increases the risk of addiction. Adolescents and young adults are particularly vulnerable to the effects of drugs and alcohol because their brains are still developing, particularly in areas related to decision-making, impulse control, and risk assessment.

A. The availability of medical insurance coverage for treatment does not directly increase the potential for addiction.

C. Cognitive deficits or vulnerabilities may predispose individuals to addiction, such as impulsivity or difficulty regulating emotions but they are not inherent characteristics of the brain.

D. Addiction can occur at any age, depending on various factors such as genetic predisposition, environmental influences, and individual vulnerabilities.
