For those who may not have had the chance to read your paper yet, could one of you briefly walk us through what motivated you to conduct this research and what your key findings were?

I'd be happy to get us started.

So we know that people with Parkinson's disease and those in the prodromal stages of Parkinson's experience cognitive concerns, and they also often experience subjective cognitive decline or subjective cognitive concerns, where they report a lot of cognitive difficulties.

They feel like they're performing poorly on their cognitive abilities, but there is a discrepancy between these self-reports and how they actually perform on objective measures of cognition.

which is known as subjective cognitive decline.

And there are cases in which subjective cognitive decline may progress to dementia.

There are cases in which it remains stable, and there are some instances in which it can be reversed.

Could you share with our audience what you think these findings could tell us about the role of psychological factors in how people evaluate their own cognitive abilities, especially in the context of Parkinson's disease?
