Introduction: Catatonia, a poorly understood syndrome challen-ging the clinician’s diagnostic and management skills, has scarce literatures regarding the clinical correlates and determining factors towards treatment response. Aim: To find the correlates of socio-demographic, clinical profile, catatonic features and identifying determining factors of treatment response to lorazepam and Modified Electroconvulsive Therapy (MECT) in catatonia. Materials and Methods: This cross-sectional study was conducted at the Department of Psychiatry, North Bengal Medical College, Siliguri, West Bengal, India from January 2020 to February 2021. The catatonia cases satisfying the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria were studied. A total of 66 patients were evaluated using the 23-item Bush Francis Catatonia Rating Scale (BFCRS) for severity and later grouped into lorazepam responder (Group I) and non responders (Group II) who received MECT. Background diagnoses using DSM-5 was made after symptom resolution. Statistical analyses like Chi-square and student’s t-test to compare frequencies and means respectively, Pearson’s and Spearman’s correlation test for bivariate correlation and linear and logistic regression to predict factors for treatment outcome were employed using Statistical Package for the Social Sciences (SPSS) 16.0 with a p-value
