Myotonic Dystrophy is a genetic disorder that affects muscle function and can cause progressive weakness and stiffness. It is caused by mutations in specific genes, leading to problems with muscle relaxation after contraction. Symptoms can vary widely among individuals and may include difficulty in walking, muscle pain, and fatigue. There are two main types of Myotonic Dystrophy: Type 1 and Type 2. Type 1 is more common and typically presents in adolescence or adulthood, while Type 2 usually appears later in life. Both types can also affect other systems, including the heart and endocrine system, leading to additional health challenges.
