I have lupus. Why do you think prednisone always helps my lightheadedness &brain fog? No exact cause of these symptoms has been found.

?lupus cerebritis? Lupus can involve brain directly and cause either low grade cognitive problems or even more severe delirium. Prednisone is both an immune modulator and anti-inflammatory, and subdues these sxs. However, there could also be underlying metabolic or chemical imbalances secondary to your regular meds or even the lupus, and that too might respond.
