New study finds seniors' brains function better in the morning

I'd heard that Alzheimer's patients often experience "sundowning" - the term for mental decline at the end of the day, but new evidence says it's more than that. The new study says older adults perform better on cognitive tests in the morning. 

According to the lead author of the research, older adults are more focused and can better ignore distractions during th emorning. In the afternoon, seniors showed signs of "idling" when researchers studied their brains with fMRIs.

The seniors who tested in the morning activated the same regions of their brain as young adults when it was time to ignore distractions.

The senior author of the paper says it's important for researchers to know this because otherwise it may give an inaccurate measurement of brain function. 

This may also explain more about why senior adults often aren't as good at driving as night. Yes, vision may play a role, but this new study may shed light on the cognitive side of things too.
