Animal model explains the origins of the cranial dystonia benign essential blepharospasm.
The current study demonstrates that combining two mild alterations to the rat trigeminal reflex blink system reproduces the symptoms of benign essential blepharospasm, a cranial dystonia characterized by uncontrollable spasms of blinking. The first modification, a small striatal dopamine depletion, reduces the tonic inhibition of trigeminal reflex blink circuits. The second alteration, a slight...

P hotophobia describes light sensitivity or abnormal intolerance of light. Patients with photophobia avoid light because of pain or discomfort. Photophobia may be reported by individuals with conditions not necessarily affecting the eye. Two such conditions are migraine and benign essential blepharospasm. We have previously demonstrated that patients with migraine or blepharospasm are more ligh...
متن کاملDry eye, blinking, and blepharospasm.
The primary purpose of the eyelids is to ensure corneal integrity. An important component of this protective function is maintaining the corneal tear film. Blink characteristics can determine tear film stability. Increasing blink amplitude thickens the lipid layer that overlies the aqueous layer of the tear film. This thickening reduces evaporation of the aqueous layer. Because each blink refor...
متن کاملComparison of the Blink Reflex and R2 Recovery Cycle Parameters Between Blepharospasm and Healthy Subjects
Background & Objective: The blink reflex recovery cycle indicates the excitability of interneurons in the brainstem. In this study, we aimed to investigate the blink reflex and R2 recovery cycle in patients with benign essential blepharospasm (BEB). Materials & Methods: This prospective case-control study compared the blink reflex and R2 recovery in 18 BEB patients with 18 age- and gender-m...
متن کاملAssociative Stimulation of the Supraorbital Nerve Fails to Induce Timing-Specific Plasticity in the Human Blink Reflex
BACKGROUND Associative high-frequency electrical stimulation (HFS) of the supraorbital nerve in five healthy individuals induced long-term potentiation (LTP)-like or depression (LTD)-like changes in the human blink reflex circuit according to the rules of spike timing-dependent plasticity (Mao and Evinger, 2001). HFS given at the onset of the R2 component of the blink reflex (HFS(LTP)) produced...
