Question

multiple choice question
neurological disorders in which the primary symptoms involve deterioration of mental functioning are classed under the global term

epilepsy.
dementia.
alzheimer.
osteoporosis.

Explanation:

We analyze each option:

• Epilepsy: A neurological disorder with seizures, not primarily mental deterioration.
• Dementia: A general term for mental deterioration, but it's a category.
• Alzheimer: A type of dementia, with primary symptom of mental function deterioration.
• Osteoporosis: A bone disorder, not neurological or about mental function.

The question asks for the disorder with primary symptom of mental function deterioration. Dementia is a broad category, and Alzheimer is a specific type under dementia with this primary symptom. But the options: "dementia" as a category (but the options are presented as single disorders? Wait, the options are epilepsy, dementia, Alzheimer, osteoporosis. Wait, the question is "Neurological disorders in which the primary symptoms involve deterioration of mental functioning are classed under the global term..." Wait, maybe the question is which is the global term. Wait, the options: dementia is the global term for disorders with mental deterioration (like Alzheimer is a type of dementia). Wait, the original question: "Neurological disorders in which the primary symptoms involve deterioration of mental functioning are classed under the global term..." So the global term is dementia. Wait, but the options: let's re - check. The options are:

• epilepsy: no, it's seizure - related.
• dementia: yes, dementia is the global term for conditions with progressive mental deterioration.
• Alzheimer: it's a type of dementia, not the global term.
• osteoporosis: bone disease, not neurological or mental.

Wait, maybe the question is which disorder has primary symptom of mental deterioration. But the options: dementia is a syndrome (global term) for mental deterioration. So the correct option is the one that is the global term. So among the options, dementia is the global term for neurological disorders with mental deterioration.

Answer:

B. dementia (assuming the options are labeled as A. epilepsy, B. dementia, C. Alzheimer, D. osteoporosis)
