- Anti-GABAA receptor encephalitis presents with age-dependent symptoms: adults commonly have seizures and cognitive/behavioral issues, often with tumors, while children frequently experience seizures and ataxia with cerebellar MRI lesions.
- MRI findings show dynamic, multifocal T2/FLAIR hyperintensities in most patients, indicating ongoing inflammation that may be clinically silent.
- Relapses are common (55% in adults) and are associated with older age and lack of second-line immunotherapy; relapses also correlate with poor long-term outcomes.
- Long-term outcomes include persistent cognitive deficits in 45% of patients and poor functional outcomes in 30%, with relapses being a predictor of worse prognosis.
- LMO5 antibodies were not detected in patients or controls, indicating they lack value as tumor markers in this condition.
- The study highlights the importance of early second-line immunotherapy to reduce relapse risk and improve outcomes in anti-GABAA receptor encephalitis.
