Stiff-Person Syndrome Market

Market Overview:

The stiff-person syndrome market reached a value of USD 119.6 Million across the top 7 markets (US, EU4, UK, and Japan) in 2024. Looking forward, IMARC Group expects the top 7 major markets to reach USD 239.6 Million by 2035, exhibiting a growth rate (CAGR) of 6.57% during 2025-2035.

The stiff-person syndrome market has been comprehensively analyzed in IMARC's new report titled "Stiff-Person Syndrome Market: Epidemiology, Industry Trends, Share, Size, Growth, Opportunity, and Forecast 2025-2035". Stiff-person syndrome is a rare autoimmune neurological condition characterized by muscle stiffness and painful spasms that occur intermittently and might worsen with time. However, some people encounter additional symptoms such as an unsteady walk, blurred vision, or slurred speech. Stiff-person syndrome is most common in people between the ages of 40 and 50, but it can also affect children and the elderly. Some common indications of this ailment include stiff muscles in the torso, arms, and legs, involuntary muscle contractions, increased sensitivity to noise and touch, emotional distress, anxiety, agoraphobia (fear of going outside), depression, high risk of falls, etc. The diagnostic evaluation of this condition is based on a comprehensive medical history, blood tests, and a physical exam. The healthcare professional might also recommend imaging studies to rule out other conditions that cause the underlying symptoms. These tests may include MRIs of the brain and spine, as well as whole-body fluorodeoxyglucose-positron emission tomography (FDG-PET) with a computerized tomography (CT) scan. Furthermore, electromyography is performed to help assess muscle activity and identify abnormal patterns in patients.

The escalating cases of autoimmune disorder, in which the immune system mistakenly attacks a protein called glutamic acid decarboxylase (GAD), leading to muscle stiffness and spasms, are primarily driving the stiff-person syndrome market. In addition to this, the inflating utilization of GABA-enhancing agents, like benzodiazepines (diazepam, clonazepam), baclofen, and gabapentin that can help alleviate symptoms by increasing GABA activity is also creating a positive outlook for the market. Moreover, the widespread adoption of physical therapy on account of its several advantages, such as reduced stiffness, improved range of motion and flexibility, and increased strength, is further bolstering the market growth. Apart from this, the rising usage of intravenous immunoglobulin (IVIg) to modulate the immune response by lowering the levels of harmful autoantibodies and preventing nerve damage, is acting as another significant growth-inducing factor. Additionally, the emerging popularity of autologous hematopoietic stem cell transplantation, since it involves using a patient's stem cells to reconstitute their immune system, is expected to drive the stiff-person syndrome market during the forecast period.
