What this trial studies

This study investigates the efficacy and safety of a synbiotic preparation combining Lactobacillus acidophilus and prebiotic fibers as an additional treatment for patients with Parkinson's disease. Participants aged 45 to 65 who are currently on dopamine replacement therapy will be enrolled. The study aims to assess whether this synbiotic approach can enhance treatment outcomes for individuals with varying stages of Parkinson's disease. The intervention involves administering 10 billion CFU of Lactobacillus acidophilus along with prebiotic fibers.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 45 to 65 with Parkinson's disease who are currently receiving dopamine replacement therapy.

Not a fit: Patients with advanced Parkinson's disease (stage 5) or those with certain comorbid conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve the management of Parkinson's disease symptoms and overall patient quality of life.

How similar studies have performed: While the use of probiotics in neurological conditions is an emerging field, this specific approach has not been widely tested, making it a novel investigation.
