vertigo
Let an agent explain vertigo and its classifications, relay causes, assessment and general management from ENT and neurology sources, describe the forms the registry aliases name, and distinguish vertigo from lightheadedness, imbalance and fear of heights, routing emergencies first and symptoms to clinicians.
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 vertigo and its classifications, relay causes, assessment and general management from ENT and neurology sources, describe the forms the registry aliases name, and distinguish vertigo from lightheadedness, imbalance and fear of heights, routing emergencies first and symptoms to clinicians.
A sensation of movement, usually spinning, when there is no actual movement, a symptom rather than a disease, classified as peripheral vertigo from inner ear causes such as benign paroxysmal positional vertigo, vestibular neuritis and Meniere disease, central vertigo from brain causes such as stroke or migraine, subjective or objective according to whether the self or surroundings seem to move, rotatory vertigo, and alternobaric vertigo from unequal ear pressure in divers and pilots. Sudden vertigo with weakness, speech or vision problems needs emergency care. The model routes people to clinicians.
What it is for: Not applicable; a symptom.
It can be explain the symptom; relay causes and assessment; route emergencies and care; distinguish related symptoms.
Distinguishing features
Illusion of motion
Symptom not disease
Peripheral or central
Emergency red flags
What it looks like
Not a visible object; a sensation, sometimes with nystagmus.
Physical character
commonest cause: benign paroxysmal positional vertigo note
lifetime prevalence of vertigo: about 7 percent - estimates
HINTS exam: bedside test to separate central from peripheral note - clinicians
How it is recognised
False sensation of movement
Peripheral, central, subjective, objective, rotatory and alternobaric vertigo
Lightheadedness is faintness; disequilibrium is imbalance; acrophobia is fear of heights

- How should clinical sources be linked?
- The registry entry has merged aliases naming classifications and causes; should they be split off?
