Overview
Based on the symptoms, dizziness may be classified into vertigo, presyncope, disequilibrium, lightheadedness.
Classification
Dizziness may be classified into subtypes based on the symptoms[1]:
| Classification of Dizziness[2] | ||
|---|---|---|
| Type of Dizziness | Description | Origin of Disorder |
| Type I Dizziness
(Vertigo) |
|
Vestibular system disorder
(Peripheral OR Central) |
| Type II Dizziness
(Impending faint/Presyncope) |
|
Non Vestibular system disorder |
| Type III Dizziness (Disequilibrium) |
| |
| Type IV Dizziness |
| |
Classification
Another way to classify is based on the timing and trigger as follows:[3]
1. New episodic:
- With triggers:
--Triggered episodic vestibular syndrome (e.g., positional vertigo from BPPV)
- Without triggers:
--Spontaneous episodic vestibular syndrome (e.g., arrhythmia from cardiac causes)
2. New continuous:
- Post-exposure acute vestibular syndrome (e.g., after gentamicin) - Spontaneous acute vestibular syndrome (e.g., stroke of posterior fossa)
3. Chronic, persistent:
- Chronic vestibular syndrome (unilateral vestibular loss, present with head movement) - Spontaneous chronic vestibular syndrome (associated with degeneration of cerebellum)
