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.aTscan can assess the dopamine transporter in a part of the brain called the striatum and can help physicians determine if the condition is caused by a dopamine system disorder; however this test cannot differentiate between MSA and Parkinsonâs disease.
