Parkinson’s disease (PD) is one of the most significant medical and social burdens of our time. It is a multifactorial neurodegenerative disorder, affecting 3.7% of the population over 65 years of age. PD involves degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNPC) with deficiency of dopamine. Anxiety is frequent in Parkinson’s disease (PD) and has a negative impact on disease symptoms and quality of life. The underlying mechanisms remain largely unknown. Several evidences provide support for involvement of the microbiota-gut-brain axis in PD pathogenesis. In this review, we intend to provide a comprehensive overview of current knowledge on how cognitive behavior deficit occur in PD, and its potential as a new target of therapeutic interventions for PD.
