LGI1 Encephalitis Overview
- LGI1 encephalitis, a common antibody-mediated condition, often affects older males in their 50s and 60s.
- It presents with focal seizures, cognitive issues, and sometimes hyponatremia, requiring tests like MRI and antibody detection.
LGI1 Diagnosis Tips
- Consider LGI1 encephalitis even if CSF is non-inflammatory, unlike other encephalitides like NMDA.
- Serum antibody testing is often more sensitive than CSF testing for LGI1.
Diagnostic Challenges in LGI1 Encephalitis
- Don't overlook subtle LGI1 symptoms; perform a thorough clinical exam.
