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.
