Spinal muscular atrophy or SMA is a genetic disorder that messes with the motor signals from the spinal cord to the brain. It cases the person to lose motor function. It’s the second most common genetic disorder that affects children, only surpass by Cystic Fibrosis. One and every forty are SMA carriers. [But it will not be pass on until two people who are carriers had a child.]
There are four types of muscular atrophy: type 1-4
Type one- sometimes called Werdnig-Hoffmann disease, begins to affect infants from birth up to 6 months of age, with most babies showing signs of the disease by 3 months. Some develop the disorder before birth. This is the most severe form of SMA.
Type two- also called chronic infantile SMA, begins to affect children between 6 and 18 months old. This form can be moderate to more severe.
Type three- also called Kugelberg-Welander disease or juvenile spinal muscular atrophy, begins to affect kids as early as 18 months of age or as late as adolescence. This is the mildest form of SMA in children
Type fosur-is the adult form of the disorder. Most people affected by this type start having symptoms after age 35, and these symptoms slowly get worse over time. Because it develops slowly, many people with type IV SMA don’t know that they have it until years after symptoms begin.
SMA is a degenerative disorder that affects every muscle in the body. It means that your muscles will waste away no matter how much physical therapy but however physical therapy is very much needed because it acts like a lifeline for a SMA patient, so that they will have the movement for as long as possible.
