Challenge your Brain. Blogging during the COVID Lockdown as a Way to Enhance Well-Being and Cognitive Reserve in an Older Population

Background: The lockdown linked with COVID-19 restrictions has been reported to have severe consequences at an emotional and cognitive level, this was especially true for vulnerable populations, such as the older adults. This study aims at exploring the effect of a blog-based intervention implemented during COVID lockdown to increase the perceived well-being and cognitive reserve (CR) of a sample of American older adults. Methods: Forty-one participants (63% female), age range from 64 to 83, participated in a blog-based 5-week intervention. Their level of well-being as well as cognitive reserve were assessed before and after the intervention with specific scales. Participants were matched by age, gender and education level to a quasi-equivalent control group living in the same area who was tested on the same variables. Results: Results showed a significant increase in both perceived well-being and CR in the intervention group. A significant difference was also found when comparing the intervention group to the matched controls.
