Primary Institution: University of California Davis, McLean Hospital/Harvard Medical School

Hypothesis

Do individual differences in diurnal cycles of cognitive function relate to cognitive health and psychosocial risk factors?

Conclusion

The study aims to determine if cognitive assessments show daily cycles and how individual differences relate to cognitive health.

Supporting Evidence

  • Previous work indicates that changes in diurnal cycles are linked to dementia and cognitive impairment.
  • Cognitive function tends to show diurnal cycles in laboratory settings.

Takeaway

This study looks at how people's thinking changes throughout the day and if those changes can tell us something about their overall brain health.

Methodology

Participants completed five surveys per day for 20 days to assess cognitive function and related factors.

Participant Demographics

Mean age of 55; 50.1% female.
