About This Condition
Multiple sclerosis is a central nervous system disease that affects millions worldwide. Although most individuals do not become severely disabled, more than half experience spasticity, which tightens muscles and can complicate daily life.
Of the estimated 2.5 million worldwide with multiple sclerosis,1 over half suffer from spasticity.2
Multiple sclerosis is a chronic, often disabling disease of the central nervous system (the brain or spinal cord).
The exact cause of multiple sclerosis is unknown. It is believed to be an autoimmune disease in which the body attacks its own myelin, a fatty tissue that helps nerve fibres conduct electrical impulses.1
Scientists don’t know what causes multiple sclerosis. Most agree that several factors are involved, including genetics, gender, and environmental triggers (possibilities include viruses, heavy metals [toxicity], and trauma).1 Multiple sclerosis is most common in Caucasians (especially Northern Europeans), women, and individuals with a genetic predisposition.1
The symptoms of multiple sclerosis can be unpredictable and vary widely from person to person. However, more than half of people with multiple sclerosis experience spasticity:2
Several tests and procedures are used to diagnose multiple sclerosis, including a complete medical history, nervous system functioning, and diagnostic test.
Two basic signs are required to confirm multiple sclerosis:1
Your clinician may diagnose you with one of many different types of multiple sclerosis. Since 1996, multiple sclerosis has been categorised in the following ways:1
Multiple sclerosis occurs most commonly in adults, but it is also diagnosed in children and adolescents.1
Spasticity is caused by damage or injury to the part of the central nervous system (the brain or spinal cord) that controls voluntary movement. This damage disrupts important signals between the nervous system and muscles, creating an imbalance that increases muscle activity or spasms.
Spasticity can make movement, posture, and balance difficult. It may affect your ability to move one or more of your limbs, or to move one side of your body. Sometimes spasticity is so severe that it gets in the way of daily activities, sleep patterns, and care giving. In certain situations, this loss of control can be dangerous for the individual.
