Spinal Muscular Atrophy (SMA) is a genetic disorder that affects muscle strength and movement. Early detection is crucial for better management.
Q: What are the early signs of Spinal Muscular Atrophy?
- Muscle weakness, particularly in the limbs.
- Reduced muscle tone (hypotonia).
- Difficulty in crawling or walking.
- Delayed motor milestones.
- Tremors in the hands.
- Weak cry or difficulty swallowing.
A: What symptoms should I look for?
- Floppy appearance due to weak muscles.
- Inability to hold head up when seated.
- Frequent falling or difficulty in standing alone.
- Fatigue during physical activities.
How does SMA progress?
| Type of SMA | Age of Onset | Symptom Onset |
|---|---|---|
| Type 1 (Werdnig-Hoffmann) | Birth to 6 months | Severe weakness, cannot sit |
| Type 2 | 6 to 18 months | Muscle weakness, can sit but not walk |
| Type 3 (Kugelberg-Welander) | 18 months to 1 year | Can walk but may eventually require assistance |
| Type 4 | Adulthood | Less severe, muscle weakness in adult years |
Common misdiagnoses for SMA:
- Cerebral Palsy
- Muscular Dystrophy
- Myopathy
