It seems there are new concerns that the ever popular Botox may do more than get rid of wrinkles. A study suggests that the botulinum toxin appears to move from its injection site to the brain. It was thought that the toxin only acted locally but now it appears it can be transported along axons to sites in the central nervous system. It is thought to have significant and long-lasting effects on neuron functions. So now they are trying to figure out how to prevent the spread or find a way to use it therapeutically. Get rid of it. There has to be some kind of backlash from injecting toxins in your body.  The toxin also moved from one hippocampus, which controls long-term memory and spatial navigation, to the hippocampus on the opposite side of the brain, and from the superior colliculus, the part of the brain associated with eye-head coordination, back to the eye. The study found that brain cell activity was disrupted both where botulinum neurotoxin was injected and in some of the distant-but-connected sites.
The study's author, Matteo Caleo of the Italian National Research Council's Institute of Neuroscience in Pisa, called the finding a concern and noted that the effects of the botulinum injection on the hippocampus were still present six months later. He said more work is needed to better understand how the toxin spreads along nerves and how to prevent the spread or use it therapeutically.
