Cushing's Syndrome is a metabolic disorder caused by excess production of corticosteroid hormones. It can be caused by a tumor or medication, prolonged exposure to cortisol, inherited disorders, or the body's overproduction of cortisol. The condition can cause psychological and physiological effects, including cognitive dysfunction, depression, muscle weakness, and cardiovascular events. Treatment options include ketoconazole, mitotane, and pasireotide. Nursing care strategies include assessment, nursing diagnosis, healthcare plan, nursing prescription, nursing evaluation, and prognosis.
