Medical disclaimer: This glossary is for education only. Sudden severe dizziness with weakness, fainting, chest pain, new severe headache, slurred speech or trouble walking needs urgent medical care.

Reference: NIDCD balance disorders overview.

This vertigo and dizziness glossary explains 50 common terms covering symptoms, inner-ear anatomy, vestibular conditions, diagnostic tests and BPPV care. Each short definition links to a fuller patient guide where more detail may be useful.

Use this page when a report, prescription, VNG result or doctor note uses a word you do not understand. This glossary supports patient education; it does not replace examination, especially when dizziness is sudden, severe, recurrent or linked with weakness, double vision, slurred speech, fainting, chest pain or new hearing loss.
