Random episodes of dizziness & lightheadedness/fainting with brain fog. BP & heart rate normal. CT scan & all blood work normal. What can it be?

Dizzyness. What a waste of money and resources doing all those tests on a 19 year old with history of anxiety, especially if liver disease is under control. If its positional, you have BPPV O/W vestibulitis, but there is no fainting. You have "panic attacks". I know most doctors practice defensive medicine especially in ER.

Revved Up. If there is no physical cause (such as heart or thyroid problems), these symptoms may be a sign of an anxiety disorder. In anxiety disorders the brain tells the body to stay in "panic" mode.

Maybe a sign of.... The slow heart rate could be a sign and not the etiology. Pts with vasodepressor syndrome or nuerocardiogenic syncope can present like this.
