You clearly had two cups of coffee this morning, but does your head still feel heavy? You have a mountain of work to do, but you keep zoning out, and even during an important conversation, you find yourself drifting off into another world. Could it be that accumulated brain fatigue has caused your concentration to drop?

Have you ever felt flustered because you forgot an important appointment or lost track of what someone just told you? Have you ever worried, asking yourself, 'What is wrong with me lately?' due to a foggy head and frustrating brain fog? This flickering forgetfulness, which nearly all of us may have experienced at least once, is not simply a matter of getting older.
