Everybody experiences "brain fog" now and again. It could be forgetfulness, confusion or just a general lack of concentration.
"Brain Fog," is a recognized term that, while not an actual medical diagnosis, could have a medical cause.
Brain fog can be a symptom of low thyroid, high blood pressure, sleep apnea or depression according to Dr. John Moon of Village Health Partners in Plano.
"The complaints are pretty vague," he said. "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."
Doctors say most of the time, it’s due to lifestyle, but in some cases there could be a medical cause.
