You most likely know that Botulinum toxin (more commonly referred to as Botox®, among other brand names) is used for cosmetic purposes to decrease wrinkles. Prior to being used in this way, Botulinum toxin was used for medical purposes to control abnormal movements. In the right hands, it can be a very effective measure to control a variety of problems related to PD.
What is botulinum toxin?
Botulinum toxin is a substance produced by the bacteria Clostridium botulinum. Botulism is caused by the harmful effects of this toxin. If the toxin enters the bloodstream, it can spread throughout the body, causing widespread muscle weakness. In its full-blown form, botulism can cause difficulty with swallowing and breathing by causing weakness of the muscles that control these functions.
The good news is that decades ago, scientists learned how to isolate the toxin and harness its power for medical use, and it can be safely injected into particular muscles in order to decrease unwanted movements of those muscles.
