Scientists found that popular anti-wrinkle treatment with Botox can pose serious health risks as the toxin may spread from face to the brain.

During a study conducted at the Italian National Research Council's Institute of Neuroscience in Pisa, scientists injected Botox into the whisker muscles of rats and found that traces of the toxin was present in the brain of the rats three days later and six months after the experiment.

Dr. Matteo Caleo, a leading author of the study said that the experiments showed that toxin spread from the area that controls long-term memory and spatial navigation to other areas of the rat's brain and was found in the part of the brain that controls eye-head coordination.
