Abstract Background Mycoplasma pneumoniae (MP) primarily causes respiratory infections but can lead to neurological manifestations. This study aimed to characterize these manifestations in adults during an epidemic. Methods The national MYCADO cohort included 1309 adults hospitalized with MP infection during the 2023–2024 French epidemic. An ancillary study identified and described MP-related central (CNS) and peripheral (PNS) nervous system manifestations. Data were retrospectively extracted from medical records, with clinical follow-up up to 3 months after discharge. Results Twenty-eight patients with neurological manifestations attributable to MP were identified (2.1% of the cohort). Of these, 19 affected the CNS, including encephalitis (n = 8), myelitis (n = 3), encephalo-myelitis (n = 2), isolated meningitis (n = 6), and cerebral vasculitis (n = 1). Nine involved the PNS: Guillain-Barré syndrome (n = 6), peripheral polyneuropathy (n = 2), and multifocal neuropathy (n = 1). The median age (interquartile range) was 35 years (29–49) years; 60.7% were men. Neurological symptoms appeared a median of 7 days after MP infection onset. Nearly half (46.4%, n = 13) required intensive care; neurological failure was the leading cause of intensive care unit transfer (12/13, 92.3%). Compared with MP patients without neurological manifestations, those with neurological involvement had longer hospital stays (13 vs 9 days; P < .001), more frequent invasive mechanical ventilation (35.7% vs 4.2%; P < .001), and more rehabilitation transfers (42.8% vs 4.3%; P < .001). At discharge, neurological sequelae were present in 47.3% of CNS patients and all Guillain-Barré syndrome (GBS) patients. At 3 months, sequelae persisted in 36.8% of CNS patients and all GBS patients. Conclusions In adults, MP infection causes rare but diverse and frequently severe neurological manifestations that worsen clinical course and result in long-term disability.
