Botulinum toxin injections have been made in our clinic for about ten years. We want to report our experiences about botulinum toxin treatment in neurologic disease. Methods In this study, the data of the patients receiving BoNT injection between January 2018 and December 2019 was retrospectively analyzed. Age, gender, botulinum toxin indications, and mean dose, duration of efficacy, side effects noted for each injection were recorded.
