Why this research matters now
The review maps the clinical spectrum of an immune-mediated post-infectious neurological syndrome across age groups and common viral triggers, which may inform recognition of ataxia syndromes following infection.
Structured evidence summary
Research question
The review synthesizes evidence on the aetiology, clinical presentation, treatment, and outcomes of post-infectious cerebellitis, including its subtypes.
Study design
PRISMA-guided systematic review of case reports, case series, and cohort studies, with qualitative synthesis of 47 studies and patient-level quantitative pooling of 73 individuals.
Population and setting
Seventy-three individuals (40 paediatric, 28 adult, 5 of unstated age band) with post-infectious cerebellitis; mean age 24.5 years (range 7 months–74 years), 72.9% male among 70 with sex reported. Patients were stratified into ACA, AC, and AFC subtypes based on neuroimaging and life-threatening features.
Main findings
SARS-CoV-2 was the most frequently identified trigger (32.9%), followed by unspecified pathogens (24.7%), varicella-zoster virus, Epstein-Barr virus, and influenza. Subtype distribution was ACA 46.6%, AC 35.6%, and AFC 17.8%, with complete recovery in 64.4% overall (58.8% ACA, 69.2% AC, 69.2% AFC). Corticosteroids were used in 74.0%, antivirals in 47.9%, and IVIG in 26.0%, with plasma exchange reserved for refractory cases. The single death occurred in an adult with COVID-19-associated necrotizing encephalopathy within the AFC subgroup.
Public-health relevance
The review maps the clinical spectrum of an immune-mediated post-infectious neurological syndrome across age groups and common viral triggers, which may inform recognition of ataxia syndromes following infection.
Important limitations
The review relies on individual case reports and small case series, with no prospective or controlled data; outcomes were not stated for 13.7% of pooled patients, and evidence quality varies by aetiology and severity subgroup. The summary here is limited to the supplied single-article abstract and metadata and requires the original paper for decision-grade interpretation.
GIDS interpretation
Within GIDS, this article is discoverable under respiratory and exanthematous viral diseases and under treatment-related topics; the abstract does not connect its findings to any live surveillance signal and none is asserted here.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
