Neurologist Dr Mahesh Jadhav explains that vertigo is a sensation of dizziness or spinning, caused by conditions like vestibular migraines, multiple sclerosis, strokes, or brainstem lesions. It can also be triggered by cerebellar tumours, vestibular neuritis, or epilepsy. Symptoms include nausea, vomiting, and difficulty walking. Identifying the root cause is crucial for treatment.
