Question

question 40
how would cerebrospinal fluid aid in alzheimers patients?
○ the csf helps clear waste from the brain during sleep
○ the csf would secrete dopamine
○ none
○ the csf helps the cerebellum perform motor control

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Cerebrospinal fluid (CSF) has a glymphatic system - related role in clearing waste (like amyloid - beta, relevant in Alzheimer's) from the brain, especially during sleep. This is consistent with what is known about CSF and brain waste clearance.
• Option 2: CSF does not secrete dopamine. Dopamine is mainly secreted by the substantia nigra in the brain.
• Option 3: Since Option 1 is correct, this is incorrect.
• Option 4: The cerebellum's motor control function is not directly related to CSF's role in aiding Alzheimer's patients. CSF's role in motor control is not the key factor in helping Alzheimer's patients, as Alzheimer's is more about brain waste and neurodegeneration.

Answer:

A. the CSF helps clear waste from the brain during sleep
