This just in: It’s harder to think when you’re tired

According to a recent study, “chemo brain” may be as much the result of fatigue and stress as of chemo. Doctors concluded this after finding out that it starts before the actual chemo, and that

Greater fatigue was correlated with poorer performance on the memory task, regardless of group.

In other words, it takes doctors repeated MRI scans to determine that tired, stressed people don’t think as well.

The obvious corollary: Maybe hospitals should look into, if you have to put people on a 24-hour IV drip, getting an IV machine that doesn’t whiffle, click, and beep next to your head all night long.

I’m just sayin’.
