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 nystagmus in general terms and point to clinical assessment and support, routing sudden new symptoms to urgent care and giving no diagnosis.

Involuntary, rhythmic movement of the eyes, which may be normal (as in optokinetic or vestibular responses) or a sign of a condition affecting the eyes, inner ear or brain; it can be present from early life or acquired.

What it is for: A clinical sign and a lifelong condition for some people.

It can be explain types of nystagmus in general terms; recognise when new symptoms need urgent care; find specialist services and support groups; find accessibility and driving information.
