# Spinal muscular atrophy: Early diagnosis can improve outcomes 2026-08-07T09:55:38+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet Spinal muscular atrophy, or SMA, is a rare inherited disorder in which motor neurons degenerate, causing progressive muscle weakness and wasting. It can affect sitting, walking, swallowing and breathing. The Hindu reports that SMA affects an estimated one to two people per 1 lakh population, with one case among 6,000 to 10,000 live births. Among Asian Indians, the estimated incidence is one in 9,655 births, while about one in 71 people is a carrier. Most cases involve changes in the SMN1 gene. Symptoms range from poor muscle tone and feeding trouble in infants to falls, fatigue and delayed milestones in older children and adults. Genetic testing confirms diagnosis. There is no cure, but disease-modifying treatments and supportive care can improve survival, movement and quality of life, especially when treatment begins before symptoms appear. ## Coverage - thehindu.com Tags: genetic testing, healthcare access, neuromuscular disorders, rare diseases, spinal muscular atrophy Canonical: https://indianopinion.org/spinal-muscular-atrophy-early-diagnosis-can-improve-outcomes/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
