Cardiologist Debunks Botox Brain Risk Myths, Highlights Real Dangers
Botox and the Brain: A Cardiologist Clarifies the Risks of Cosmetic Procedures Madrid, Spain – Dr. Aurelio Rojas Sánchez, a cardiologist and scientific communicator, recently addressed public concerns regarding the potential for botulinum toxin (Botox) to travel from injection sites to the brain. In a widely viewed online video, Dr. Rojas explained the scientific understanding of this aesthetic procedure. Drawing on animal studies, Dr. Rojas noted that research has demonstrated retrograde transport of botulinum neurotoxin A (BoNT/A) and E (BoNT/E) from injection sites to central neurons, affecting proteins such as SNAP-25. He clarified, however, that these findings in animal models do not directly translate to human experiences with typical cosmetic doses. "In humans, at usual aesthetic doses, the action is local, and cases of neurological effects due to 'distant dissemination' are extremely rare," Dr. Rojas stated, referencing studies that support this distinction. He emphasized that there is no solid evidence of chronic neurological damage from properly administered cosmetic treatments. However, he acknowledged that in cases where much higher doses are used for therapeutic purposes, such as treating dystonias, some diffusion of effects has been documented. Dr. Rojas concluded that when Botox procedures are performed by qualified professionals using correct doses and appropriate techniques, the neurological risk is minimal. He highlighted that the primary dangers stem from the use of adulterated products, those of dubious origin, or excessive dosages. He urged individuals who have undergone such treatments to seek immediate medical attention if they experience symptoms like weakness, loss of strength, changes in voice, or difficulty swallowing in the days following the procedure. The cardiologist underscored the importance of informed decision-making for those considering aesthetic treatments, stressing that ongoing research continues to refine our understanding of botulinum toxin's effects.
