What is Stiff-Person Syndrome, Diagnosis, and Treatment

Super Admin


1. Understanding Stiff-Person Syndrome

Stiff-Person Syndrome, also known as Moersch-Woltman Syndrome, affects the central nervous system, impacting the brain or spinal cord. While it can occur at any age, it's more common in individuals aged 30 to 60, with a rarity of only 1 in 1,000,000.

This autoimmune neurological disorder causes muscle stiffness, either spontaneously or triggered by stimuli like noise, movement, stress, or touch. Over time, this stiffness affects posture, spinal shape, and can lead to mobility loss.

Risk factors include conditions like diabetes, autoimmune disorders, and certain cancers.

2. Identifying Symptoms

Symptoms can develop gradually over months to years, varying in severity and presentation. Initially, stiffness occurs in the trunk and abdomen, spreading to other body parts. Patients experience pain, restricted movement, and eventual posture changes.

Continuous stiffness leads to a stooped posture and difficulty walking. Muscle spasms, sensitivity to noise and light, anxiety, and depression are common symptoms.

3. Exploring the Causes

Though exact causes remain elusive, researchers suggest an autoimmune origin. Patients may have antibodies against glutamic acid decarboxylase (GAD) enzymes, though not always.

4. Diagnosis and Treatment

Diagnosis involves clinical assessment, blood tests, electromyography, and imaging. Treatments aim to manage symptoms:

- Medications like benzodiazepines, muscle relaxants, anti-seizure drugs, and steroids.
- Psychological therapies.
- Other options include immunoglobulin therapy, plasma exchange, and physical therapies like hydrotherapy and acupuncture.
