Overview

The objective of this randomized, triple-blind, placebo-controlled clinical trial is to compare NANO-PSO therapy against placebo in improving cognitive abilities in older adults with mild to moderate non-vascular cognitive impairment over six months of treatment. The primary questions it aims to answer are:

• Does NANO-PSO therapy improve cognitive abilities in older adults with mild to moderate non-vascular cognitive impairment over six months of treatment compared to placebo?

The researchers will compare NANO-PSO therapy against placebo to see if it benefits the cognitive abilities of geriatric patients.

Participants will be required to:

• Consume two capsules of NANO-PSO or placebo daily in the morning for six months.
• Be evaluated monthly by phone to identify potential risks and ensure adherence to the treatment.
• Be evaluated in person at 90 and 180 days of treatment.
• The patient or primary caregiver must maintain a log to confirm daily dose consumption and will have a direct communication line with the attending physicians in case of questions about ingestion or possible adverse reactions.
• At the end of the final patient evaluation, a quality questionnaire will be administered.
