Atrophy is the progressive degeneration or shrinkage of muscle or nerve tissue. In multiple sclerosis (MS
multiple sclerosis (MS
Approximately 15% of those with MS show a slow deterioration from the onset. In the second form, 10% have either primary-progressive MS (PPMS) and never experience acute disease attacks or 5% have what was termed progressive-relapsing MS (PRMS), and have occasional subsequent attacks.

), two types of atrophy are common: muscle atrophy (due to disuse of specific muscles) and brain or cerebral atrophy
cerebral atrophy
Cerebral atrophy is a common feature of many of the diseases that affect the brain. Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.

People can treat muscle atrophy by making certain lifestyle changes, trying physical therapy, or undergoing surgery. In this article, we look at some other causes, symptoms, and treatments of muscle atrophy.

What are the different types of atrophy?

The different types of atrophy include Glandular Atrophy, Vaginal Atrophy, Skeletal Muscle Atrophy, Spinal Muscular Atrophy, and Multiple System Atrophy. Skeletal Muscle Atrophy is separated into either Disuse Atrophy or Neurogenic Atrophy. There are treatments that can address the different types of atrophy. These treatments can be noninvasive or invasive, depending on the type of atrophy. Only a series of testing and diagnosis of symptoms by a physician can determine if an individual is suffering from atrophy, and what course of action should be taken to mitigate its progression.

What is spinal muscular atrophy?

Spinal Muscular Atrophy – Spinal muscular atrophy is a genetic condition caused by the loss of nerve cells that control muscle movement throughout the body. With this form of atrophy, the muscles closer to the center of the body become weaker than other muscles. Adult-onset spinal muscular atrophy (also known as spinal muscle atrophy type 4, or SMA 4) is a disorder that affects control of muscle movement.
