This study describes one young woman with ME/CFS whose main problem was brain fog and difficulty thinking clearly. Doctors found an abnormal brain wave pattern on her EEG scan and treated her with two techniques: neurofeedback (training to change brain wave patterns) and self-hypnosis. She felt significantly better, with improvements in fatigue and mental clarity that lasted for at least 9 months.
This study contributes to growing evidence that ME/CFS involves measurable brain dysfunction and suggests that brain-targeted interventions may help reduce symptoms, particularly cognitive impairment. For patients struggling with brain fog, this case offers a potential alternative approach worth exploring in larger trials.
This single-case report cannot prove that neurofeedback and self-hypnosis are effective treatments for ME/CFS generally, nor can it establish causation between the observed EEG abnormality and symptom improvement. The lack of a control group or blinding means improvement could be due to placebo effect, natural recovery, or other unmeasured factors. Results from one patient cannot be generalized to the broader ME/CFS population.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
