Results: Treated groups showed significant improvement in all parameters: body weight, fasting blood glucose, fasting insulin level, HOMA-IR, pro-inflammatory cytokines (INF-γ and IL1-β), malondialdehyde (MDA), super-oxide dismutase (SOD), cortisol level, serotonin, and dopamine, assess of depressive behavior by; open field test, tail suspension test, and improvement in the histopathological changes of the brain.
