Abstract:
Macrophagic myofasciitis (MMF) is an emerging condition, characterized by specific muscle lesions assessing long-term persistence of aluminum hydroxide within macrophages at the site of previous immunization. Affected patients mainly complain of arthromyalgias, chronic fatigue, and cognitive difficulties. We designed a comprehensive battery of neuropsychological tests to prospectively delineate MMF-associated cognitive dysfunction (MACD). Compared to control patients with arthritis and chronic pain, MMF patients had pronounced and specific cognitive impairment. MACD mainly affected (i) both visual and verbal memory; (ii) executive functions, including attention, working memory, and planning; and (iii) left ear extinction at dichotic listening test. Cognitive deficits did not correlate with pain, fatigue, depression, or disease duration. Pathophysiological mechanisms underlying MACD remain to be determined. In conclusion, long-term persistence of vaccine-derived aluminum hydroxide within the body assessed by MMF is associated with cognitive dysfunction, not solely due to chronic pain, fatigue and depression.
Insights
Macrophagic myofasciitis (MMF), linked to persistent aluminum hydroxide from vaccines, causes significant cognitive dysfunction. This impairment affects memory and executive functions, independent of pain or fatigue.
Area of Science:
- Immunology
- Neurology
- Toxicology
Background:
- Macrophagic myofasciitis (MMF) is an emerging condition linked to aluminum hydroxide persistence post-vaccination.
- Patients often report arthralgias, chronic fatigue, and cognitive difficulties.
Purpose of the Study:
- To prospectively delineate MMF-associated cognitive dysfunction (MACD) using a comprehensive neuropsychological test battery.
- To compare cognitive function in MMF patients versus controls with arthritis and chronic pain.
Main Methods:
- A battery of neuropsychological tests was administered to MMF patients and controls.
- Cognitive performance was assessed, focusing on memory, executive functions, and auditory processing.
Main Results:
- MMF patients exhibited pronounced and specific cognitive impairments compared to controls.
- Deficits were observed in visual and verbal memory, attention, working memory, planning, and left ear extinction.
- Cognitive deficits did not correlate with pain, fatigue, depression, or disease duration.
Conclusions:
- Long-term persistence of vaccine-derived aluminum hydroxide, as indicated by MMF, is associated with cognitive dysfunction.
- MMF-associated cognitive dysfunction is distinct from symptoms of chronic pain, fatigue, and depression.
