brain fog
Clouded thinking state
Brain fog is a state of mental cloudiness—difficulty concentrating, thinking clearly, or retrieving words.
It's not a medical diagnosis but a common complaint describing cognitive sluggishness: I've had brain fog all day and can't focus on anything.
Causes range from sleep deprivation and stress to illness, medication side effects, or hormonal changes.
