So stress can affect anyone who feels overwhelmed â even kids. In preschoolers, separation from parents can cause anxiety. As kids get older, academic and social pressures (especially from trying to fit in) create stress. Many kids are too busy to have time to play creatively or relax after school.
Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue, with or without the breakdown of nerve tissue.here are nine types of muscular dystrophy, with each type involving an eventual loss of strength, increasing disability, and possible deformity. The most well known of the muscular dystrophies is Duchenne muscular dystrophy (DMD) , followed by Becker muscular dystrophy (BMD) .
Different types of muscular dystrophy affect specific groups of muscles, have a specific age when signs and symptoms are first seen, vary in how severe they can be, and are caused by imperfections in different genes. Muscular dystrophy can run in the family, or a person might be the first one in their family to have the condition. Muscular dystrophy is rare, and there is not a lot of data on how many people are affected by the condition. Much of the information comes from outside the United States. CDC scientists are working to estimate the number of people with each type of muscular dystrophy in the United States.
