Reducing Drooling

One unpleasant effect of cerebral palsy and neurological disorders is that they can cause sialorrhea, or uncontrollable drooling, in both children and adults, which can be so severe the patients actually become dehydrated as a result. It also creates hygienic problems, and makes it more difficult for people living with the disorders to feel comfortable interacting with the non-disabled world.

Over the past decade, though, Botox has emerged as a treatment to curb drooling. In a 2005 study, British researchers found that injecting the toxin into the salivary glands in multiple spots helped 70 percent of young subjects to reduce their sialorrhea symptoms. The treatment lasted up to 12 months before the children needed repeat injections.

Dr. Tony Ward, a British physician who used Botox to treat adults with the same problem, reported that it was similarly effective and improved patients' quality of life. "I had one patient who went through 120 boxes of tissues every month," he told BBC News. "Drooling can be very distressing."

A 2012 study by South Korean researchers also achieved impressive results, with 12 of 17 patients showing a more than 50 percent reduction in drooling [source: Jeung, et al.].
