Stop Calling Everything ‘Chakkar’: 3 Different Conditions That Mimic Each Other | PRIME ENT Center
BPPV (Benign Paroxysmal Positional Vertigo): Seconds-long spinning triggered by specific head movements, caused by loose crystals in the inner ear. Treatable with Epley Maneuver (success rate 80-90%).
Vestibular Neuritis: Viral inflammation of the balance nerve causing persistent dizziness lasting hours to days. Self-limiting; recovery occurs with central compensation.
Posterior Circulation Stroke: Dangerous condition mimicking vestibular neuritis but identified by failing the HINTS exam (Head Impulse, Nystagmus, Test of Skew). Requires immediate emergency intervention.
