MSA is broken down into two main subtypes based on the predominant symptom: MSA-predominant Parkinsonism (MSA-P), and MSA-predominant cerebellar ataxia (MSA-C). Multiple system atrophy (MSA) is a progressive neurodegenerative disorder characterized by a combination of symptoms that affect both the autonomic nervous system (the part of the nervous system that controls involuntary action such as blood pressure or digestion) and movement.

All generally result in worsening muscle weakness associated with muscle twitching. The main cause of muscle wasting is a lack of physical activity. The most well known of the muscular dystrophies is Duchenne muscular dystrophy (DMD), followed by Becker muscular dystrophy (BMD). Common examples are: • Atrophy of notochord & thyroglossal ducts during fetal development • Atrophy of uterus after parturition.
