The blink reflex recovery cycle differs between essential and presumed psychogenic blepharospasm.
Summary of "The blink reflex recovery cycle differs between essential and presumed psychogenic blepharospasm."
Psychogenic blepharospasm is difficult to distinguish clinically from benign essential blepharospasm (BEB). The blink reflex recovery cycle measures the excitability of human brainstem interneurons and is abnormal in BEB. We wished to study the blink reflex recovery cycle in patients with atypical (presumed psychogenic) blepharospasm (AB).

Medical and Biotech [MESH] Definitions
Attentional Blink
Temporary visual deficit or impaired visual processing occurring in a rapid serial visual presentation task. After a person identifies the first of two visual targets, the ability to detect the second target is impaired for the next few hundred milliseconds. This phenomenon is called attentional blink.
Reflex, Abdominal
Contractions of the abdominal muscles upon stimulation of the skin (superficial abdominal reflex) or tapping neighboring bony structures (deep abdominal reflex). The superficial reflex may be weak or absent, for example, after a stroke, a sign of upper (suprasegmental) motor neuron lesions. (Stedman, 25th ed & Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p1073)
Reflex, Babinski
An abnormal reflex consisting of dorsiflexion of the great toe and abduction of the other toes in response to cutaneous stimulation of the plantar surface of the foot.
H-reflex
A monosynaptic reflex elicited by stimulating a nerve, particularly the tibial nerve, with an electric shock.
Reflex, Stretch
Reflex contraction of a muscle in response to stretching, which stimulates muscle proprioceptors.
