Spinal Muscular Atrophy (SMA) is a genetic condition affecting the nerve cells responsible for muscle movement. Often striking during infancy, it leads to muscle weakness and atrophy, gradually impairing physical abilities. Perform a search online to learn more about SMA signs and treatment.
Signs and symptoms
Recognizing the signs of SMA is crucial for early intervention and management. While symptoms may vary depending on the type and severity of SMA, some common indicators include:
- Muscle weakness: Infants with SMA may exhibit delayed motor milestones, such as difficulty holding their head up, rolling over, or sitting.
- Floppy appearance: Reduced muscle tone, often noticeable in the limbs and trunk, can give an infant a “floppy” appearance.
- Difficulty breathing: As SMA affects the muscles responsible for breathing, respiratory problems can arise, especially during sleep.1
- Feeding challenges: Swallowing difficulties may lead to poor feeding and inadequate weight gain.
- Tremors: Involuntary shaking or trembling in the limbs may occur.
- Scoliosis: A sideways curvature of the spine can develop due to weakened back muscles.
Effective treatment
Although SMA remains incurable, significant advancements in treatment have emerged, offering hope to individuals affected by this condition. These treatments aim to slow disease progression, improve muscle function, and enhance overall quality of life.
- Nusinersen (Spinraza): This groundbreaking medication, administered via spinal injections, has revolutionized SMA treatment. Nusinersen works by increasing the production of a protein essential for motor neuron survival, thereby slowing the degeneration of nerve cells.
- Risdiplam (Evrysdi): Another oral medication, Risdiplam, offers a convenient treatment option for SMA patients. It functions similarly to Nusinersen, enhancing the production of the same crucial protein, but can be taken at home, eliminating the need for invasive spinal injections.
- Gene therapy (Zolgensma): A one-time gene therapy, Zolgensma, represents a transformative approach to SMA treatment. It involves delivering a functional copy of the defective gene responsible for SMA directly into the body’s cells, potentially halting disease progression and improving motor function.2
Prognosis and Complications
The prognosis for individuals with SMA varies depending on the type and severity of the condition. Early diagnosis and prompt treatment can significantly improve outcomes and enhance quality of life. However, SMA can lead to severe complications, including respiratory failure, pneumonia, and scoliosis, which may require ongoing medical management and support.
