Solution:
The muscular dystrophies (MD) are a group of inherited genetic conditions that gradually cause the muscles to weaken, leading to an increasing level of disability. MD is a progressive condition, which means it gets worse over time. Alzheimer's disease is a progressive degenerative disorder that causes brain cells to waste away (degenerate), leading to dementia. Cystic fibrosis is also a hereditary progressive degenerative disorder that affects the lungs and digestive system. Thick and sticky mucus is produced that clogs the lungs, obstructing the pancreas.
