Details and patient eligibility

About

Bilingualism has been shown to have a strong protective effect against dementia, delaying the diagnosis of Alzheimer's disease by up to 4 years. The purpose of the study is to test whether learning a second language using Duolingo software could improve cognitive functions in older adults.

Full description

This study is a 3-arm, randomized controlled trial. The primary objective of the study is to test the impact of second language acquisition through short-term use of the Duolingo app on cognitive functioning, particularly executive function in older adults compared to a brain training application.
