Differentiation of central facial paralysis and peripheral facial paralysis

Central facial paralysis and peripheral facial paralysis differentiation mainly through paralysis site, clinical manifestations, onset speed and other aspects of differentiation.

1, paralysis site

Central facial paralysis is generally upper motor neuron paralysis, mainly caused by motor center and motor center downward pyramidal tract damage. Peripheral paralysis is generally lower motor neuron paralysis, mainly caused by nerve damage outside the brain and spinal cord.

2, clinical manifestations of different

Central paralysis mainly to myotonia, myotonic muscle atrophy and other symptoms, accompanied by pathological reflexes, generally will not appear muscle fascicular fibrillation. Peripheral paralysis can appear muscle atrophy, muscle tone decline and other symptoms, generally no pathological signs, but there will be muscle fascicular fibrillation.

3, onset speed of

central facial paralysis faster, can be in a few seconds or minutes. Peripheral facial paralysis onset speed is slower, may occur in a few hours or days.
