Multiple system atrophy (MSA) is primarily considered a neurodegenerative disorder with no established link to head or neck injuries as a direct cause. While some research has suggested a possible association between traumatic brain injury and various neurodegenerative conditions, MSA itself is not specifically linked to such trauma. The exact cause of MSA remains unclear, but it is thought to involve a combination of genetic and environmental factors. Therefore, while head or neck injuries may influence other neurological conditions, they are not recognized as a cause of MSA.
The cause of MSA has not been identified. MSA occurs in the general population in a sporadic manner. The disorder is degenerative and progressively worsens.

Focal atrophy refers to the localized loss of tissue within a specific area of an organ or structure in the body. It can result from a variety of factors, such as aging, disease, or injury, and may lead to functional impairment in the affected area. Treatment options for focal atrophy depend on the underlying cause and may include medications, physical therapy, or surgical interventions.
