Muscular dystrophy (MD) refers to a group of genetic disorders that cause progressive weakness and degeneration of the skeletal muscles.
Muscles are composed of thousands of fibers, each made up of cells that are encased by a protective outer layer called the membrane. The fibers are grouped together and supported by connective tissue to form individual muscles.
A group of proteins called dystrophin-glycoprotein complex, found within the muscle membrane, prevents damage during muscle contractions. When this protective membrane is damaged, muscle fibers lose the protein, absorb excess calcium, and suffer damage, leading to progressive degeneration.
MD may arise due to various causes, including defects in the dystrophin-glycoprotein complex, abnormalities in connective tissue, or toxic gene products in muscle fibers. These disruptions impact muscle structure and function, resulting in the characteristic muscle degeneration seen with MD.
Muscular dystrophy is categorized based on the following factors:
- Extent and pattern of muscle weakness
- Age at which symptoms begin
- Rate of progression
- Severity of symptoms
- Family history of the condition
There are several types of muscular dystrophy, with Duchenne muscular dystrophy (DMD) being the most common and severe form. DMD typically affects young boys.
Other forms of muscular dystrophy include Becker, Myotonic, Facioscapulohumeral, and Limb-Girdle muscular dystrophy. Each form of MD has its unique symptoms and progression rate.
Over time, these conditions can impair mobility, respiratory function, and heart health, significantly impacting quality of life. Symptoms vary but often include difficulty walking, frequent falls, muscle stiffness, and challenges with everyday activities like climbing stairs or lifting objects.
Alpenglow Homecare, through Colorado Medicaid’s IHSS and HCBS programs, provides invaluable support for caregivers and their loved ones living with muscular dystrophy. We assist caregivers in creating personalized care plans that address essential daily tasks, mobility support, and medical care, ensuring a safe and comfortable home environment for people living with MD.
