Multiple Sclerosis (MS) is a disease that inhibits the communication between your brain, spinal cord, and the rest of your body causing an array of different symptoms. This happens because the immune system begins to attack the myelin sheath around neurons. The myelin sheath surrounds axons (or nerve fibers) of some neurons, creating a protective layer around the axon which facilitates the travel of electrical impulses across the nerve fiber. When the myelin sheath is deteriorated, communication between your brain and other parts of the body becomes inhibited. As a result, a range of symptoms might occur such as:
- Double vision
- Numbness in extremities
- Tingling in parts of body
- Speech problems
- Loss of coordination 
Unfortunately, there are no known causes for MS, but there are certain risk factors like family history of MS or your biological sex. For instance, women are more likely to receive it than men, but men normally experience more sever forms. MS is also more common in European-American individuals as opposed to African, Asian, or Native American individuals.
There is no one test to see if you have MS. If you are experiencing these symptoms, then you should go talk to a neurologist who can determine how to proceed.
Multiple Sclerosis and Aging
MS can impact people as young as 20 and may be diagnosed after the age of 50. It is usually diagnosed in between this age range, but some individuals do develop it later on in life. If you or a loved one is over 50 and has MS and if you need care services at home, then there are some home care options to choose from. Nurse registries like ElderCare at Home can help find you a certified aide in order to assist with everyday activities. To contact ElderCare at Home, please call 888-285-0093 or visit our website for more information. You can also contact your local Area Agency on Aging to find out about resources near you.
