A progressive disorder characterized by the loss of higher-order cerebral functions is
(a) Parkinson's disease
(b) Parasomnia
(c) Huntington's disease
(d) Alzheimer's disease

검증된 단계별 안내

Step 1: Understand the key phrase in the question: 'progressive disorder characterized by the loss of higher-order cerebral functions.' Higher-order cerebral functions include memory, reasoning, language, and problem-solving, which are primarily associated with the cerebral cortex.

Step 2: Review the options given: (a) Parkinson's disease, (b) Parasomnia, (c) Huntington's disease, and (d) Alzheimer's disease. Consider the main characteristics of each disorder.

Step 3: Recall that Parkinson's disease mainly affects motor control due to loss of dopamine-producing neurons in the basal ganglia, not primarily higher-order cerebral functions.

Step 4: Recognize that parasomnia refers to abnormal behaviors during sleep, such as sleepwalking, and is not a progressive loss of cerebral functions.

Step 5: Differentiate between Huntington's disease and Alzheimer's disease: Huntington's involves motor dysfunction and cognitive decline, but Alzheimer's disease is specifically known for progressive loss of memory and other higher-order cerebral functions, making it the best fit for the description.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Higher-Order Cerebral Functions

Higher-order cerebral functions include complex brain activities such as memory, reasoning, language, and problem-solving. These functions are primarily managed by the cerebral cortex and are essential for cognitive abilities and daily functioning.

Alzheimer's Disease

Alzheimer's disease is a progressive neurodegenerative disorder characterized by the gradual loss of memory and other higher-order cerebral functions. It primarily affects older adults and leads to cognitive decline, behavioral changes, and impaired daily activities.

Differentiation from Other Neurological Disorders

Understanding the differences between disorders like Parkinson's disease, Huntington's disease, and parasomnia is crucial. Parkinson's mainly affects motor control, Huntington's involves genetic neurodegeneration with movement and cognitive symptoms, while parasomnia relates to abnormal sleep behaviors.
