Blepharospasm is a fairly rare disease. Estimates of incidence and prevalence vary, tending to be higher in population studies than service studies, [5] likely because of delays in diagnosis. [4]
The main symptoms involve involuntary blinking and chin thrusting. Some patients may experience excessive tongue protrusion, squinting, light sensitivity, muddled speech, or uncontrollable contraction of the platysma muscle. Some Meige's patients also have "laryngeal dystonia" (spasms of the larynx). Blepharospasm may lead to embarrassment in ...
Idiopathic craniofacial erythema is a medical condition characterized by uncontrollable and frequently unprovoked facial blushing.. Blushing can occur at any time and is frequently triggered by even mundane events, such as talking to friends, paying for goods in a shop, asking for directions or even simply making eye contact with another person.

Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...
