Spinal muscular atrophy or SMA is a disease that is triggered by the breakdown of nerve cells in the brain and the spinal cord. This, in turn, affects the brain’s ability to transmit messages that control the movements of the muscles. It is most likely to affect babies and young kids, making it difficult for them to use their muscles effectively.

SMA or spinal muscular atrophy is a group of genetic disease that causes weakness and wasting of voluntary muscles. A person suffering from SMA cannot control the movement of their muscles. One of the major reasons a person suffers from this disease is the loss of nerve cells in the spinal cord and brainstem.

Spinal Muscle Atrophy or SMA is a hereditary disease that affects the spinal cord, gradually attacking the lower motor neurons, causing the muscles to get weaker. The symptoms of spinal muscular atrophy significantly vary depending on the type of condition. SMA in children is divided into three types: type 1, type 2, and type 3; whereas, type 4 is an adult-onset.

Living with a chronic condition is never easy, but when the chronic condition affects the individual’s mobility, it becomes all the more difficult to function. One such condition that affects the muscles throughout the body is spinal muscular atrophy (SMA). It especially affects the breathing muscles and renders the arms and legs frail.

Spinal Muscle Atrophy, also known as SMA, is a genetic disorder that creates several barriers in a person’s muscle movements. The condition often occurs when the spinal cord and the brainstem have a loss of specialized motor neurons. This loss of motor neurons leads to muscle weakness and muscle wasting, which causes several physical disabilities such as the inability of walking, crawling, sitting straight up, and even controlling head movements.

Top 3 DNA test kits to consider buying in 2018 Before the invention of DNA test kits, genealogists relied on simple oral and written records to trace an individual’s family, heritage, and ancestry. Today, however, you can make use of new-age DNA test kits that help in scientifically tracing your roots.
