ABSTRACT A few studies have shown that serum brain-derived neurotrophic factor (BDNF) level in post-stroke depression is highly correlated with memory and neuropsychiatric disturbances. Objective: This study aimed to elucidate the relationship of serum BDNF, malondialdehyde (MDA), and 8-Hydroxy 2-Deoxyguanosine (8-OhdG) levels in acute stroke cases with one-month post-stroke depression. Methods: An observational study was conducted of 72 post-ischemic stroke patients in the Neurology ward of the Dr. M. Djamil Hospital, Padang, West Sumatra, Indonesia. Acute stroke (< 48 hours) serum BDNF, MDA, and 8-OhdG levels were measured using ELISA. Based on observations using the Hamilton Depression Rating Scale conducted one month after stroke, respondents were divided into two groups: with and without depression. The mean serum level was analyzed using the t-test and Mann-Whitney test, while differences in basic characteristics were analyzed using the Chi-square test. Multivariate analysis was conducted to determine the most significant factor associated with post-stroke depression. The error rate was set at 5%. Results: BDNF levels in acute stroke were significantly lower in the depression group than in the non-depression group (p < 0.05). MDA and 8-OhdG levels in acute stroke were higher in the depression group (p < 0.05). BDNF level during acute stroke was negatively correlated with post-stroke depression, while, conversely, acute stroke MDA and 8-OhdG levels were positively correlated with depression. Conclusion: BDNF had a negative correlation, while MDA and 8-OhdG had a positive correlation, with depression one-month post-stroke. 8-OhdG was the most influential factor in post-stroke depression.
