4 Treatment Options for Spinal Muscular Atrophy
Spinal muscular atrophy (SMA) is a neuromuscular disorder caused by the absence or deficiency of full-length survival motor neuron protein (SMN). SMN is essential for developing growth or protrusions in the nerves called dendrites and axons. Dendrite and axons transmit impulses to and from neurons (brain cells) and from neurons to muscles. The absence of SMN disrupts this process, and the muscles do not receive signals from the brain. The muscles stop growing and begin to weaken, and then start shrinking. Children and infants with spinal muscular atrophy are unable to perform motor movements as they grow. They also have problems breathing and swallowing. Some types of SMA can lead to fatalities within a few weeks of birth. There is no cure for SMA yet. However, treatment aims to increase life expectancy and their quality of life through increased SMN production. Treatment begins immediately on a diagnosis. Read on to know the treatment options for spinal muscle atrophy. 1. SMN enhancing treatment The goal of this treatment is to increase the production of SMN1. Such protocols are known as SMN-enhancing treatments. Nusinersen was the first approved drug to treat both children and adults. The drug is administered into the fluid around the spinal cord.
