Abstract
Parkinson’s disease (PD) is an age-associated, progressive, and common neurodegenerative disorder. It is characterized by dopaminergic neuron degeneration in the substantia nigra pars compacta. The involvement of oxidative stress, inflammation, and dysbiosis in PD has been confirmed and probiotics also have the ability to regulate the mentioned mechanisms. Here, we assessed probiotics supplementation effects on experimental model of PD. Thirty Male Wistar rats were divided into three groups for a 14-day treatment. It was shown that a mixture of probiotics containing Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus reuteri, and Lactobacillus fermentum could improve rotational behavior, cognitive function, lipid peroxidation, and neuronal damage in the group received probiotic supplementation compared to the other groups (P < 0001, P < .001, and P = .026, respectively). Taken together, these findings revealed that probiotics supplementation could be an appropriate complementary treatment for PD.
