Spinal muscular atrophy (SMA) poses significant challenges for older adults, leading to muscle weakness and atrophy that can disrupt mobility and daily activities. Common symptoms include difficulties in walking, climbing stairs, and lifting items.
What Are SMA Symptoms?
Spinal muscular atrophy (SMA) is a genetic disorder that affects the nerve cells that control muscle movement. It can cause muscle weakness and atrophy, which can impact mobility and daily activities. SMA is caused by a mutation in the SMN1 gene, which is responsible for producing the protein SMN. SMN is essential for the survival of motor neurons, which are the nerve cells that control muscle movement. Without enough SMN, motor neurons die, leading to muscle weakness and atrophy.
SMA is classified into several types, with SMA type 1 being the most severe. SMA type 1 typically presents in infants and is characterized by severe muscle weakness and atrophy, affecting the muscles used for breathing and swallowing. SMA types 2 and 3 are less severe and typically present in childhood or adolescence. SMA type 4 is the mildest form and usually presents in adulthood.
SMA Symptoms To Watch For
The symptoms of SMA can vary depending on the type and severity of the condition. Some common symptoms to watch for include:
- Muscle weakness in the arms, legs, and trunk
- Difficulty walking, climbing stairs, or lifting objects
- Muscle twitching or tremors
- Difficulty breathing or swallowing
- Scoliosis (curvature of the spine)
- Joint contractures (stiffness of the joints)
- Speech problems
- Feeding difficulties
SMA Symptoms That Impact Daily Life
SMA can have a significant impact on daily life, affecting mobility, independence, and overall quality of life. Individuals with SMA may experience difficulty performing everyday tasks such as walking, climbing stairs, getting dressed, and bathing.
They may also require assistance with breathing and swallowing. SMA can also lead to social isolation and depression, as individuals with SMA may feel self-conscious about their condition and may have difficulty participating in activities that they used to enjoy.
Learn More About SMA
If you or a loved one is experiencing symptoms of SMA, it is important to see a doctor for diagnosis and treatment. There are several treatments available for SMA, including medication, physical therapy, and occupational therapy. Early diagnosis and treatment can help to improve symptoms and slow the progression of the condition.
