Understanding All Types of SMA
Spinal Muscular Atrophy (SMA) is a genetic condition that affects muscle strength and movement in different ways, depending on the type:
• Type 1: Symptoms appear early in infancy and are the most severe.
• Type 2: Symptoms start in childhood; mobility varies widely.
• Type 3: Symptoms appear in later childhood or adolescence; many can walk with support.
• Type 4: Adult-onset with milder symptoms.
No matter the type, early diagnosis and intervention can make a big difference in quality of life. Raising awareness helps ensure those affected get the support and resources they need. 💜
