Can Botox cause the brain to stop using a muscle, resulting in a permanent effect?

Long term use of botox should cause a weakness in the muscle-similar to 'disuse atrophy'-meaning that the less you use it, the weaker it becomes. Kind of like if you stop going to the gym after a lifetime of working out, your muscles become smaller.Best.

Botox results are not permanent. Botox results resolve in 3-4 months. However, Botox can prevent areas from worsening and in this case, will help the muscle atrophy, appearing smaller. Best, Dr. Emer
