Stiff person syndrome (SPS) is a rare, progressive syndrome that affects the nervous system, specifically the brain and spinal cord. Symptoms may include extreme muscle stiffness, rigidity and painful spasms in the trunk and limbs, severely impairing mobility.
Thereof, how common is stiff person syndrome?
Stiff person syndrome (SPS) affects only about one or two in a million people. Being diagnosed with this very rare condition can leave patients and families with many questions and few answers.
Also, is Stiff person syndrome terminal?
Researchers are not sure of the exact cause stiff person syndrome. However, they believe it to be an autoimmune disorder, a condition where your immune system attacks healthy cells. This protein is found in nerve terminals and is involved in helping nerve cells communicate with each other.
Do I have stiff person syndrome?
Symptoms may include extreme muscle stiffness, rigidity and painful spasms in the trunk and limbs, severely impairing mobility. Spasms can generate enough force to fracture bone. People with SPS often have heightened sensitivity to noise, sudden movements, and emotional distress, which can set off muscle spasms.
What autoimmune disease causes tight muscles?
Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
