Thyroid auto‐antibodies in newly diagnosed multiple sclerosis patients: A cross sectional study

Multiple sclerosis (MS) is a chronic inflammatory disease in which the immune system attacks the myelin sheath of the central nervous system (CNS). It has been proposed that autoimmune conditions may occur together and an individual's immune system may attack more than one system. Autoimmune thyroid disease is one of the most common comorbidities along with MS. Since thyroid hormones are crucial for normal brain function and remyelination, we aimed to determine the prevalence of thyroid dysfunction in a group of MS patients compared with healthy controls.
