Sleep and executive functions in older adults: A systematic review
ABSTRACT Introduction: A recent increase in studies suggests a role of age-related sleep changes in executive functions (EF). However, this relationship remains unclear and mixed results have emerged. Objective: To investigate how age-related sleep changes may play an important role in the exten...

ABSTRACT Introduction: A recent increase in studies suggests a role of age-related sleep changes in executive functions (EF).

Methods: A systematic strategy was employed to identify the available literature on age-related sleep changes and EF. Results: Of the 465 studies identified, 26 were included.
