Tinkering to Flex Ur Brain (Tinker-FUN): A Cognitive Flexibility Pilot Program for Community Dwelling Older Adults
The Tinker-FUN program is a cognitive flexibility intervention designed to help older adults adapt to aging and live independently. While cognitive training is an effective way to mitigate cognitive decline, current methods do not focus on cognitive flexibility, an essential aspect of managing daily activities as one ages. The intervention aims to address this gap by offering engaging tinkering activities designed for older adults. Before expanding to a larger clinical trial, the current proposal seeks to test its feasibility among community-dwelling older adults in US.
