Some researchers have suggested that draining excess fluid from the brain might help relieve symptoms in a small number of people with chronic fatigue syndrome, but there is no scientific proof this works.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review could determine whether all published clinical reports of CSF drainage in chronic fatigue syndrome show consistent, reproducible symptom improvement beyond placebo effects.
A systematic review and meta-analysis of all published case reports, case series, and observational studies reporting clinical outcomes (fatigue, cognition, pain) in patients with chronic fatigue syndrome who underwent CSF drainage procedures, with standardized outcome measures, risk-of-bias assessment, and comparison to natural history data.
An RCT could determine whether CSF drainage produces clinically meaningful symptom improvement in chronic fatigue syndrome compared to a sham procedure.
A double-blind, sham-controlled RCT of 80 adults with severe, treatment-refractory chronic fatigue syndrome (Canadian Criteria), randomized to receive lumbar CSF drainage (15–20 mL) or sham procedure (needle insertion without fluid removal), with primary outcomes of change in fatigue severity (FIS-40) and cognitive performance (PASAT) at 4 and 12 weeks, and secondary outcomes of CSF biomarkers and MRI glymphatic metrics.
A cohort study could determine whether patients with chronic fatigue syndrome who undergo CSF drainage have sustained symptom improvement over time compared to those who do not.
A prospective cohort study following 100 patients with severe chronic fatigue syndrome who are candidates for CSF drainage, comparing those who undergo the procedure to those who do not, with outcomes measured at 6, 12, and 24 months using validated fatigue, cognitive, and quality-of-life scales, while controlling for baseline severity and comorbidities.
A case-control study could determine whether patients with chronic fatigue syndrome who improved after CSF drainage differ in biomarker profiles from those who did not.
A case-control study comparing 30 patients with chronic fatigue syndrome who showed >30% improvement in fatigue after CSF drainage to 30 matched non-responders, analyzing pre- and post-procedure CSF biomarkers (amyloid-β, tau, neurofilament light), glymphatic MRI metrics, and intracranial pressure measurements.
A case series could document whether any individuals with chronic fatigue syndrome experienced symptom improvement after CSF drainage, generating hypotheses for future testing.
A case series of 10–15 patients with severe chronic fatigue syndrome who underwent lumbar CSF drainage, with detailed pre- and post-procedure assessments of fatigue, cognition, pain, sleep, and CSF biomarkers, and MRI glymphatic metrics, with blinded outcome evaluation.
