Some causes of blepharospasm have been identified; however, the causes of many cases of blepharospasm remain unknown. Some people with blepharospasm have a history of dry eyes, light sensitivity, and even fatigue. Others report no eye problems before onset of<unk> s. Some drugs can induce blepharospasm, such as those used to treat Parkinson's disease, as well as hormone treatments, including estrogen-replacement therapy for women going through menopause. Blepharospasm can also be a<unk>  of acute withdrawal from benzodiazepines. Prolonged use of benzodiazepines can induce blepharospasm and is a known risk factor for the development of blepharospasm. Blepharospasm may also come from abnormal functioning of the brain's basal ganglia. Simultaneous dry eye and dystonias such as Meige's syndrome have been observed. Blepharospasms can be caused by concussions in some rare cases, when a blow to the back of the head damages the basal ganglia. Multiple sclerosis can cause blepharospasm.
