Prosopoplegia

Prosoplegia is a disorder of the innervation of the facial muscles, consisting of their unexpected contraction. It usually develops as an independent disease, but can be part of a systemic syndrome, for example, in multiple sclerosis. The random nature of movement disorders in cases of prosoplegia is explained by infectious diseases suffered in childhood. The prosoplegic reaction is classified as a benign hyperkinesis of childhood.

Prosoplegia is a violation of the motor functions of the facial muscles while other muscle groups are intact. In other words, the patient has disturbances in facial expression, but the muscles of the arms and legs are not affected. Loss of mobility of facial muscles for any reason is explained by the pathophysiological concept of the lateral representation of the innervation of the cranial nerves.

Most experts today adhere to the point of view on the nature and pathogenesis of the disorder according to the model of the generalized muscular system. It is also known that damage to the facial nerve affects the lower half of the face and then its rotation in the opposite direction if the left nerve is affected or the counterattack if there is damage to the right nucleus. Similarly, wounding of the parasympathetic nucleus substance solves the problem of bending and turning of the lateral movements of the face, providing a downward or upward rotation.

If a person loses control and control over his upper or lower parts, then this pathological phenomenon is called prosoplegia. All these physiological phenomena can lead to cross-damage of various facial muscles, in which they will not be able to control any movement or movement of a part of the face. In other words, a prosoplegic patient is completely deprived of the ability to control facial movements and expresses not what he feels, but a completely indifferent neutral expression. Hence the name itself - prosophonia (blanc face from English "white face"). How
