Low-dose glucocorticoid therapy complements the pituitary-adrenocortical system and reduces anxiety and insomnia in myasthenia gravis patients.

Myasthenia gravis (MG) is an autoimmune disorder generally mediated by antibodies against the acetylcholine receptors of the skeletal muscles. Depending on the disease burden, MG patients may experience chronic dysregulation of both the hormonal stress axis and the immune system, consequently, aggravating the disease itself but also leading to secondary psychopathological abnormalities. A long-term clinical course requires long-term glucocorticoid (GC) therapy, which may change the psychological state by affecting the pituitary-adrenocortical system in MG patients.
