Summary
Hyponatremia at diagnosis is linked to higher relapse risk and poor outcomes in anti-leucine-rich glioma-inactivated protein 1 (LGI1) encephalitis. This finding aids in risk stratification for LGI1 encephalitis patients.
Area of Science:
- Neurology
- Immunology
- Clinical Medicine
Background:
- Anti-leucine-rich glioma-inactivated protein 1 (LGI1) encephalitis poses a significant risk of relapse and functional impairment.
- Current treatment guidelines lack established maintenance strategies for LGI1 encephalitis.
Purpose of the Study:
- To identify prognostic signatures for anti-LGI1 encephalitis.
- To determine predictors of relapse and poor outcomes using real-world data.
Main Methods:
- A multicenter retrospective study of 104 anti-LGI1 encephalitis patients from Eastern China (2015-2024) with over 24-month follow-up.
- Relapse defined as new/worsening symptoms after 3 months of stability; poor outcome defined as modified Rankin Scale score > 2.
Main Results:
- Hyponatremia at diagnosis was more frequent in patients who relapsed (p=0.017) and significantly increased relapse risk (HR=4.67, p=0.012).
- Male sex (OR=5.12, p=0.041) and hyponatremia (OR=4.69, p=0.008) were associated with poor outcomes.
- 11.5% of patients experienced relapse, and 16.3% had poor outcomes.
Conclusions:
- Hyponatremia is a key predictor of relapse and poor outcomes in anti-LGI1 encephalitis.
- Findings support individualized risk stratification for LGI1 encephalitis.
- Further validation in prospective studies is recommended.

Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
