Introduction: The clinical features of Acute Encephalitis syndrome (AES) vary widely across the world and little documentation is available from
North Bengal. Materials and methods: A cross –sectional observational study was conducted at the Department of Medicine of a teaching
hospital in North Bengal. 104 AES cases were enrolled and clinically evaluated and investigated as per the study protocol. Results:JE (72%) was
most common causative agent followed by HSV Encephalitis (11.5%), Scrub Typhus (9.6%) and Dengue Encephalitis (2.88%). Male cases were
predominant than female in our study. Fever and altered sensorium were most common presentation followed by seizures (51.9%), headache
(29.8%), vomiting (18.2%), and hemiplegia (4.8%). Neurological evaluation revealed 80% of the patients had neck stiffness followed by positive
Babinski sign (45.19%) and hypertonia (35%). Conclusions: JE is the commonest cause of AES in North Bengal and seizures are the commonest
neurological manifestation after altered sensorium.
