Effectiveness of a Probiotic K10 in Managing Health Outcomes in Parkinson's Disease and in Early Stage (Mild Cognitive Impairment to Mild Dementia) and Alzheimer's Disease

Brief summary (registry, in English)
Evaluation of the effects of the K10 probiotic mix in patients with degenerative neurological diseases (Parkinson and Alzheimer's) with a focus on cognitive, motor and psychiatric neurological evaluation. Single-centre, double-blind, placebo-controlled randomized clinical trial (RCT), Interventional Model: Parallel Assignment, phase III study. Two groups will be composed, with two arms each, 1 group composed of patients with Parkinson's and 1 group with patients with Alzheimer's, 52 patients in each group. The first arm of each group will receive placebo and the other arm of each group will receive the mix K10. In this study, researchers will conduct a randomized, placebo-controlled, phase III trial of a probiotic preparation (Probiotic K10) to evaluate its use as a viable treatment option for neurodegenerative disorders, including Parkinson's disease (PD) and Alzheimer's disease. of Alzheimer (AD). This formulation has been previously demonstrated to improve cognitive function, systemic inflammation, systemic oxidative stress in Alzheimer's patients. The main objective of this study is to compare its effect with placebo on cognitive status in individuals with AD and PD, the UPDRS total score in people with early PD and quality of life, and the measurement of caregiver burden in AD and PD. Participants will be randomly assigned to receive a placebo (an inactive substance) and a K10 probiotic (dose 30.000.000 CFU/day). They will be evaluated at baseline, 45 days and 90 days.
