Blepharospasm (BSP) is an adult onset focal dystonia characterized by stereotyped, bilateral, and synchronous spasms of the orbicularis oculi muscles (Defazio et al., 2017). The neurophysiological hallmark of BSP is an enhanced excitability of blink reflex circuits in the brainstem, as evaluated by the recovery cycle of the R2 component of the blink reflex (Defazio et al., 2017), which is possibly due to a lack of inhibition from basal ganglia structures.

Abstract
Blepharospasm (BSP) is an adult onset focal dystonia characterized by stereotyped, bilateral, and synchronous spasms of the orbicularis oculi muscles (Defazio et al., 2017). The neurophysiological hallmark of BSP is an enhanced excitability of blink reflex circuits in the brainstem, as evaluated by the recovery cycle of the R2 component of the blink reflex (Defazio et al., 2017), which is possibly due to a lack of inhibition from basal ganglia structures.| File | Dimensione | Formato | |
