Over the years, many researches have shown the potential protective effects of ginseng for preventing and treating neurological damage and their related diseases. Neuronal disturbance is one of the most common serious effects of cisplatin chemotherapy that triggers memory impairment and cognitive disability. Based on the hypothesis that mechanistic pathways of ginseng against the neurological and biochemical disturbance remain unclear, therefore, this study was designed to investigate the neuroprotective effect of ginseng extract against neurological and behavior abnormality induced by cisplatin in male rats. Animals were divided into 4 groups. Group 1 served as a control, group 2 was orally administrated with ginseng (100 mg/kg BW) daily for 90 days, group 3 was injected intraperitoneally with cisplatin (4 mg/kg BW) once a week for 90 days, and group 4 received ginseng and cisplatin. Cisplatin induced a learning and memory dysfunction in the Morris water maze task and locomotor disability in the rotarod test. In addition, cisplatin disrupted the oxidant/antioxidant systems, neuroinflammatory molecules (TNF-α, IL-6, IL-12, and IL-1β), neurotransmitters, and apoptotic (caspase-3, P53, and Bax) and dementia markers (amyloid-β40 and amyloid-β 42). Co-treatment with ginseng extracts successfully ameliorated the cognitive behaviors and intramuscular strength and presented a good protective agent against neurological damage. Histopathological and histochemical studies proved the neuroprotective effect of ginseng. Our data showed that ginseng capable to counteract the memory dysfunction is induced by cisplatin via reducing oxidative stress and neuroinflammation restoring the neurological efficiency.
