Stiff-person syndrome (SPS) is a rare neurological disorder characterized by progressive muscle stiffness and rigidity, painful muscle spasms, and heightened sensitivity to noise, touch and emotional distress. Symptoms that occur randomly or can be triggered by a variety of stimuli. SPS is an autoimmune disease that is often comorbid with diabetes, thyroiditis, vitiligo and pernicious anemia. The condition affects twice as many women than men, and treatments, including medications, focus on the specific symptoms in each individual.
Organizations exist to help and support those dealing with Stiff-person syndrome in their lives.
