Study Summary

This trial will use a medicine that blocks a chemical called "acetylcholine" to study how it affects attention in people with Sickle Cell Disease. They think that people with SCD have to work harder to pay attention, and disrupting this process with the medicine will make it harder to pay attention.

Who is the study for?
This trial is for non-smoking adults aged 55 or older who have mild cognitive issues but are generally in good health. They should score above 25 on the MoCA test, indicating only slight memory concerns, and have a GDS rating below 3, showing minimal daily life impact.Check my eligibility
What is being tested?
The study tests how an anticholinergic drug called Mecamylamine affects attention in aging individuals with slight cognitive decline. Participants will be compared to those taking a placebo while their brain activity and attention performance are monitored using EEG and specific tests.See study design
What are the potential side effects?
Mecamylamine may cause side effects like dizziness, nausea, dry mouth, constipation, blurred vision or confusion. These symptoms result from its action on the nervous system but vary among individuals.
