Everybody experiences "brain fog" now and again. It could be forgetfulness, confusion or just a general lack of concentration. Most of the time it's harmless, but sometimes there is a medical cause.
After a busy day at her shoe stores, A'lisa Adams can always count on one thing: The brain fog that hits in the afternoon.
"I might not even remember what shoe I'm supposed to pull or the person I'm supposed to pull it for, or you're ringing somebody up and you're missing items," said A'lisa Adams, shoe store owner.
Brain fog slows her down, makes her forgetful and worries her too.
"Am I beginning to lose my memory? Are there other things and conditions out there that make you worry that maybe this isn't right?" said Adams.
Family physician Dr. John Moon says brain fog can be a symptom of low thyroid, high blood pressure, sleep apnea or depression.
"The complaints are usually pretty vague, when patients come in, they have a hard time explaining exactly what they're feeling, but it's usually being unfocused, having a hard time concentrating at work, being tired," said Dr. Moon.
But for many people, lifestyle is to blame: stress, bad diets and lack of exercise.
"If they're concerned, it's something that's interfering with their day, it's something they would want to go check with a doctor to make sure there's not something correctable outside of changing diet and maybe better sleep," said Moon.
If your symptoms are new or if they worry you, check with your doctor. If there is a medical condition, treating it may help you clear the fog.
