Comment: Temple lobes and parietal lobes lesion are common in patients

with HSV encephalitis accounted for 70,8% and 29,2%. Thalamic lesion

was the most common in JE accounted for 48,5%. Lesion of temporal

lobes, parietal lobes, frontal lobes, cerebellum, central gray nucleus,

thalamus and white matter differ between different groups by causes.

Comment: Acute encephalitis with unknown cause had the highest

mortality rate of 15,6%, HSV encephalitis had the highest mortality

46,8%. Mortality rates, sequelae and recovery among the etiologic

groups were different with statistically significant at p < 0,001.

Comment: Severe prognostic factors in patients with JE were:

mechanical ventilation, glasgow score on admission ≤ 8 points, glasgow

score decreased after 24 hours, hyper/hypotonic abnormal images on

MRI. Multivariate regression analysis failed to find independent

predictors
