facial paralysis
Let an agent explain facial paralysis in general terms, relay causes, the peripheral-versus-central distinction and management from neurology sources, route stroke and sudden weakness emergencies, describe the named forms, and distinguish facial paralysis from Bell s palsy as one cause, stroke, other cranial nerve palsies and facial numbness, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain facial paralysis in general terms, relay causes, the peripheral-versus-central distinction and management from neurology sources, route stroke and sudden weakness emergencies, describe the named forms, and distinguish facial paralysis from Bell s palsy as one cause, stroke, other cranial nerve palsies and facial numbness, without diagnosing individuals.
Weakness or loss of movement of the muscles of the face, caused by damage to the facial nerve or its control, with forms the registry aliases name such as unilateral facial nerve palsy, central facial palsy from a brain problem, congenital facial paralysis and asymmetric crying facies in newborns; common causes include Bell s palsy, stroke, infections, tumours and injury. Whether the forehead is affected helps distinguish a nerve problem from a stroke, and sudden facial droop, especially with other stroke signs, is a medical emergency, so anyone with new facial weakness should seek urgent assessment.
What it is for: Not applicable; a neurological sign.
It can be explain causes and the peripheral-central distinction; relay management; route emergencies; describe named forms.
Distinguishing features
Facial muscle weakness
Peripheral or central
Forehead involvement clue
Many causes
What it looks like
Drooping or immobility of part or all of one or both sides of the face.
Physical character
nerve: facial nerve, cranial nerve VII note
forehead sparing: suggests a central cause note
registry parents: facial nerve disease, cranial nerve palsy note
How it is recognised
Weakness or loss of facial movement
Unilateral facial nerve palsy, asymmetric crying facies, central facial palsy, congenital facial paralysis
Bell s palsy is one cause; stroke is central; other cranial nerve palsies affect other functions; facial numbness is sensory not motor
