You’re having a conversation, and suddenly you can't remember the right word -- or the wrong words come tumbling out of your mouth. You're cooking dinner, the timer's going off, but you can't remember why you set it.
When brain fog clouds your thinking, you may feel frustrated or embarrassed. You may also wonder what it means for your MS. But don’t worry. It happens. With your doctor’s help and some new techniques, you can learn ways to work around it.
Your doctor will decide which type of botulinum toxin is appropriate for you.
Despite the fact that the drugs are used for a variety of medical problems, the FDA, as of this date, has not yet approved the use of these treatments for MS-related spasticity. Botox, Myobloc, Xeomin, and Dysport are approved by the FDA for the treatment of a condition marked by repetitive contraction of the neck muscles (cervical dystonia), chronic migraine headaches, and uncontrollable blinking of the eyelids (blepharospasm). Botox is commonly used to treat wrinkles.
What Is Spasticity?
Spasticity refers to a wide range of involuntary muscle contractions that result in muscle spasms or stiffness. Spasticity interferes with voluntary muscle movement and usually involves the muscles of the legs and/or arms.
Spasticity is the result of an imbalance in the central nervous system, caused by a trauma or disease in the brain and/or spinal cord. This imbalance causes hyperactive muscle stretch reflexes, which result in involuntary contractions and increased muscle tone.
Some doctors believe that an increased sensitivity in the parts of the muscles that are responsible for contracting (tightening), relaxing and stretching the muscles contribute to spasticity.
How Does Botulinum Toxin Work?
Normally, the nerves in the body send electrical messages to the muscles so that they will contract and move. This messages are transmitted from the nerves to the muscles by a substance called acetylcholine. Botulinum toxin works to block the effect of acetylcholine on the muscle, resulting in weakness or paralysis.
