Overview
The pathophysiology of dizziness depends on the etiological subtype including orthostatic hypotension, benign paroxysmal positional vertigo, Meniere's disease, Parkinson's disease, hyperventilation syndrome, peripheral neuropathy, and vestibular migraine.
Pathophysiology
The pathophysiology of dizziness depends on the etiological subtype, and area of pathology involved[1][2][3][4][5].
| Cause | Pathophysiology | Category of dizziness |
|---|---|---|
| Orthostatic hypotension | It is a drop in blood pressure on changing the position or can be due to the side effect of the medicine | Presyncope |
| Benign paroxysmal positional vertigo | The semicircular canal contains loose otolith, which gives a false sense of motion. | Vertigo |
| Meniere's disease | Excessive endolymphatic fluid in the inner ear | Vertigo |
| Hyperventilation syndrome | Hyperventilation leads to respiratory alkalosis | Lightheadedness |
| Peripheral neuropathy | Decrease tactile sensation may cause patients to lack the feeling of feet to be touched to the ground leading to falls and imbalance. | Disequilibrium |
| Parkinson disease | Gait dysfunction cause falls and imbalance | Disequilibrium |
| Vestibular migraine | Uncertain | Vertigo |
The pathophysiology of dizziness can be explained according to one of its classification systems based on central and peripheral, although there is often overlap between the two.[6]
