CFS Cognitive and Neurological Aspects of CFS 3

Question 1

The tilt table test is used in CFS assessment primarily to evaluate:

Accepted Answer

Orthostatic intolerance and autonomic nervous system function

Answer

The tilt table test measures how the body responds to positional changes, making it useful for diagnosing orthostatic intolerance and autonomic dysfunction in CFS patients.

Question 2

Functional MRI (fMRI) studies during cognitive tasks in CFS patients typically show:

Accepted Answer

Altered or increased activation patterns suggesting compensatory neural recruitment

Answer

fMRI studies in CFS show altered or increased activation in brain regions during cognitive tasks, suggesting the brain recruits additional neural resources to compensate for reduced processing efficiency.

Question 3

The two-day cardiopulmonary exercise test (2-day CPET) in CFS specifically demonstrates:

Accepted Answer

Significant decline in performance on the second test day

Answer

The 2-day CPET shows a significant decline in peak oxygen uptake and anaerobic threshold on the second test day in CFS patients, providing objective physiological evidence of post-exertional malaise.

Question 4

EEG (electroencephalography) abnormalities reported in CFS research include:

Accepted Answer

Abnormal slow-wave activity and reduced alpha power

Answer

EEG studies in CFS have found abnormal slow-wave activity and reduced alpha frequency power, suggesting altered brain electrical patterns consistent with neurological dysfunction.

Question 5

Quantitative sensory testing (QST) in CFS research is used to measure:

Accepted Answer

Sensory thresholds and pain sensitivity

Answer

Quantitative sensory testing measures sensory thresholds and pain sensitivity to standardized stimuli, helping identify central sensitization and sensory processing abnormalities in CFS.
