How might hereditary geniospasm be treated?

Hereditary geniospasm, which may also be referred to as hereditary essential chin myoclonus, is generally considered a benign disorder although in some cases it can cause anxiety and social embarrassment.[1] Significant improvement with age has been reported.[2] Several drugs are used to treat myoclonus, such as benzodiazepines and anticonvulsants. However, individuals may not respond to a single medication and may experience significant side effects if a combination of drugs is used. It has also been suggested that botulinum toxin be considered as a primary treatment because it has been shown to be effective and well tolerated.[1]
