Paroxysmal Kinesigenic Dyskinesia Symptoms Markedly Reduced with Parenteral Vitamins and Minerals: A Case Report.
Bruton, Alisha, Fuller, Leslie · The Permanente journal · 2019 · DOI
Quick Summary
This report describes one woman who had both a rare movement disorder (paroxysmal kinesigenic dyskinesia) and chronic fatigue syndrome. When she received weekly injections of vitamins and minerals, her movement disorder symptoms almost completely went away, and she was able to return to her normal daily activities. Genetic testing found several mutations that may help explain why this treatment worked so well for her.
Why It Matters
This case is relevant to ME/CFS patients because it describes a comorbid presentation and explores whether micronutrient supplementation may help manage symptoms in patients with certain genetic profiles. For researchers, it raises questions about potential metabolic or genetic factors that could underlie symptom severity in ME/CFS and suggests parenteral nutrition as a potential therapeutic avenue worth investigating in controlled studies.
Observed Findings
A 61-year-old woman with 13-year history of PKD and comorbid chronic fatigue syndrome received weekly parenteral vitamins and minerals
Symptomatic improvement was marked, with almost complete elimination of PKD episodes between treatments
The patient was able to return to activities of daily living after treatment initiation
Genetic testing revealed several mutations that may explain the apparent treatment efficacy
The patient had previously refused antiseizure medication due to concerns about fatigue exacerbation
Inferred Conclusions
Parenteral vitamin and mineral supplementation may be beneficial for PKD symptoms in patients with certain genetic profiles
Genetic mutations identified in this patient may predispose to micronutrient deficiency or malabsorption that responds to parenteral therapy
Parenteral supplementation may be a viable alternative for patients who cannot tolerate conventional antiseizure medications due to fatigue concerns
Remaining Questions
Would parenteral vitamins and minerals be equally effective in other PKD or ME/CFS patients without these specific genetic mutations?
Which specific vitamins or minerals in the parenteral formulation were responsible for the symptomatic improvement?
What This Study Does Not Prove
This single case report cannot prove that parenteral vitamins and minerals are an effective treatment for ME/CFS or PKD in general populations. It does not establish causation—the improvement could be due to placebo effect, natural disease fluctuation, or other concurrent changes. The genetic mutations identified are correlational findings that do not definitively explain the treatment mechanism, and results from one patient cannot be generalized to others.
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 →
