Understanding Stiff Person Syndrome (SPS)

Prevalence of Stiff Person Syndrome SPS

SPS is incredibly rare, with only a handful of documented cases worldwide. The exact prevalence is uncertain, but it is believed to affect approximately 1 in 1 million individuals. Its rarity adds to the enigma surrounding the condition.

Causes of Stiff Person Syndrome SPS

The exact cause of Stiff Person Syndrome remains a mystery. While there is no definitive answer, it is thought to be related to autoimmune dysfunction.

Symptoms and Diagnosis

Characteristic Symptoms

The hallmark of SPS is persistent muscle stiffness, often likened to being “frozen” or “stiff as a board.” This stiffness can be triggered by emotional distress or sudden movements. Muscle spasms and painful muscle contractions are also common, making simple tasks like walking or standing extremely challenging.

Diagnosing SPS

Diagnosing SPS is a complex process, as it often mimics other neurological conditions. A comprehensive review of one’s medical background, a thorough physical evaluation, and the requirement for specialized tests are imperative. These may include electromyography (EMG) and blood tests to detect the presence of specific antibodies associated with the disorder.
