Macrophagic myofasciitis (MMF) is characterized by specific muscle lesions assessing long-term persistence of aluminum hydroxide within macrophages at the site of previous immunization. Affected patients are middle-aged adults, mainly presenting with diffuse arthromyalgias, chronic fatigue, and cognitive dysfunction. Representative features of MMF-associated cognitive dysfunction (MACD) include (i) dysexecutive syndrome; (i) visual memory; (iii) left ear extinction at dichotic listening test. In present study we retrospectively evaluated the progression of MACD in 30 MMF patients. Most patients fulfilled criteria for non-amnestic/dysexecutive mild cognitive impairment, even if some cognitive deficits seemed unusually severe. MACD remained stable over time, although dysexecutive syndrome tended to worsen. Long-term follow-up of a subset of patients with 3 or 4 consecutive neuropsychological evaluations confirmed the stability of MACD with time, despite marked fluctuations.
Graphical abstractMacrophagic myofasciitis (MMF) is characterized by long-term persistence of aluminum hydroxide within body, years after immunization. MMFassociated cognitive dysfunction (MACD) is characterized by dysexecutive syndrome, memory impairment and interhemispheric deconnexion. Long-term follow-up of MMF patients indicates that MACD remains stable over time, despite fluctuations.Figure optionsDownload full-size imageDownload as PowerPoint slide
