1. dizziness non-specific term that encompasses vertigo, imbalance, etc.
2. vertigo the sensation of self-motion when no self-motion is occurring or the sensation
of distorted self-motion during an otherwise normal head movement (internal as
opposed to external - which falls in vestibulo-visual symptoms category)
3. dizziness the sensation of disturbed or impaired spatial orientation without a false or
distorted sense of motion (by definition these are non-vertiginous symptoms)
4. vestibulo-visual visual symptoms that usually result from vestibular pathology or the interplay
symptoms between visual and vestibular systems, includes false sensations of motion or tilting
of the visual surround and visual distortion (blur) linked to vestibular (rather than
optical) failure
5. postural symp- balance symptoms related to maintenance of postural stability, occurring only
toms while upright (seated, standing, walking)
6. diplopia, dyspha- "Ds" - central symptoms you wouldn't expect with peripheral vestibular pathology
gia, dysarthria,
dysmetria, asym-
metrical muscle
weakness
7. vestibular crisis sudden onset of vertigo improving from continuous to head motion provoked over
several days
8. memorable, ver- labyrinthine or VIII nerve symptoms: sudden __ onset with __ at onset, paroxysmal
tigo, 24 hours, 2 sponanteous events <__, head movement provoked symptoms <__, more likely to
minutes, audito- have __ involvement

9. central vestibular or non-vestibular symptoms: sudden onset __, lightheadedness,
