Psychiatric symptoms delay the diagnosis of anti-LGI1 encephalitis
This is the first study to analyze the detailed profiles and prognostic implication of the psychiatric symptoms in patients with anti-LGI1 encephalitis.
•
Of 16 patients, more than a half of the patients (10, 62.5%) presented psychiatric symptoms as the initial manifestation of the encephalitis.
•
The presence of initial psychiatric symptoms delayed the time to the first-line immune therapy, affecting the subacute and final outcome of the patients.
•
Initial manifestation of psychiatric symptoms in patients with anti-LGI1 encephalitis is a poor prognostic factor, misleading both the patients and the clinicians.
