Vertigo is a sensation of spinning or dizziness that occurs when a person feels as if they or their surroundings are moving when they are not. It is often caused by issues in the inner ear, brain, or sensory nerve pathways. Common conditions that can lead to vertigo include benign paroxysmal positional vertigo (BPPV), Meniere's disease, and vestibular neuritis. Symptoms of vertigo can include a feeling of imbalance, nausea, and difficulty focusing. It can be triggered by changes in head position or movement. Treatment options vary depending on the underlying cause and may include medications, physical therapy, or lifestyle changes.
