Comprehensive Overview of Spinal Muscular Atrophy: Symptoms and Early Indicators

Spinal Muscular Atrophy (SMA) is a hereditary condition that affects the spinal cord, causing progressive deterioration of motor neurons and muscle weakness.

The presentation of SMA varies based on its type. It typically appears in children as type 1, type 2, and type 3, whereas type 4 occurs in adults.

Important signs and symptoms to watch for include:

Type 1
This severe subtype appears in infants, leading to muscle weakness that impairs breathing and swallowing. Babies often have limp limbs and feeding difficulties.

Symptoms usually become noticeable by around 6 months old. Children with type 1 SMA face serious health challenges, including a higher risk of respiratory failure, and may develop spinal problems like scoliosis.

Type 2
Known as chronic infantile SMA, this form affects children aged 6 to 18 months, primarily impairing leg muscles with moderate to severe symptoms.

Kids may have difficulty standing or walking unaided and might need assistance to move. Respiratory complications can also occur.

Type 3
Symptoms show up between ages 2 and 17, often called juvenile SMA or Kugelberg-Welander disease. Children may struggle with climbing stairs, running, or getting up from a seated position. While some can walk initially, many eventually rely on wheelchairs.

Type 4
This adult-onset variant typically appears after age 35, characterized by weakening muscles, twitching, and breathing problems, mainly affecting hips, legs, and arms.
