Overview
The pathophysiology of dizziness depends on the etiological subtype.
Pathophysiology
The pathophysiology of dizziness depends on the etiological subtype[1][2][3][4][5].
| Cause | Pathophysiology | Catogery 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 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 |
