Vertigo is a sensation of spinning or dizziness, often described as feeling like you or your surroundings are moving or spinning when they are not. It can be a distressing and disorienting experience that affects balance and spatial orientation. Here's a deeper understanding of vertigo:

​

1. Types of Vertigo: Vertigo can be categorized into two main types: peripheral vertigo and central vertigo. Peripheral vertigo is typically related to problems in the inner ear or vestibular system, while central vertigo is associated with issues in the brain or central nervous system.

2. Causes: Peripheral vertigo is commonly caused by conditions such as benign paroxysmal positional vertigo (BPPV), Meniere's disease, vestibular neuritis, and labyrinthitis. These conditions can result from inner ear infections, inflammation, or disturbances in the vestibular system. Central vertigo may be caused by more serious conditions such as stroke, brain tumors, or multiple sclerosis, which affect the brain's ability to process sensory information.

3. Symptoms: The primary symptom of vertigo is a sensation of spinning or whirling, which may be accompanied by nausea, vomiting, sweating, unsteadiness, and difficulty walking or standing. Symptoms can range from mild to severe and may last for a few seconds to several hours.

4. Diagnosis: Diagnosing vertigo involves a thorough medical history, physical examination, and possibly additional tests such as vestibular function tests, hearing tests, imaging studies (MRI or CT scans), and electronystagmography (ENG) to evaluate eye movements.

5. Prognosis: The prognosis for vertigo varies depending on the cause and individual factors. Many cases of peripheral vertigo resolve on their own or with treatment, while central vertigo may require ongoing management and monitoring. Some people may experience recurrent episodes of vertigo, while others may have symptoms that gradually improve over time.

Overall, vertigo is a complex and multifaceted condition that can have a significant impact on daily life. Early diagnosis and appropriate management are crucial for minimizing symptoms, improving quality of life, and reducing the risk of complications.
