🧠 What is Vertigo?
Vertigo is a subtype of dizziness characterized by a false sensation of movement, typically spinning (rotational illusion), either of the patient or the environment.
It reflects dysfunction within the vestibular system (peripheral or central).
⚙️ Pathophysiology
Balance depends on integration of:
- Vestibular input (inner ear)
- Visual input
- Proprioception
🔹 Peripheral vertigo
- Originates from inner ear (labyrinth, semicircular canals)
- Abnormal endolymph movement or otolith displacement
🔹 Central vertigo
- Originates from brainstem or cerebellum
- Impaired neural processing of balance signals
📌 Common Causes of Vertigo
🟢 Peripheral causes (most common)
- Benign Paroxysmal Positional Vertigo (BPPV)
- Vestibular neuritis
- Ménière’s disease
- Labyrinthitis
🔴 Central causes (serious)
- Cerebellar stroke
- Multiple sclerosis
- Brain tumors
🔵 Other triggers
- Migraine-associated vertigo
- Ototoxic medications
🧾 Clinical Presentation
Symptoms include:
- Spinning sensation
- Nausea and vomiting
- Nystagmus
- Postural instability
⚠️ Red Flags (suggest central cause)
- Severe headache
- Neurological deficits
- Ataxia
- Diplopia
🧪 Diagnostic Approach
🔍 Clinical examination
- Detailed history (onset, duration, triggers)
- Dix-Hallpike maneuver (BPPV diagnosis)
🧫 Additional tests
- Audiometry
- Vestibular testing
🧠 Imaging
- MRI (suspected central pathology)
⚖️ Differential Diagnosis
- Presyncope (cardiovascular)
- Disequilibrium (neurological)
- Anxiety-related dizziness
💊 Treatment Strategies
🔹 1. BPPV Management
- Epley maneuver (first-line)
- Canalith repositioning techniques
🔹 2. Vestibular Neuritis
- Corticosteroids (early phase)
- Vestibular rehabilitation
🔹 3. Ménière’s Disease
- Low-sodium diet
- Diuretics
- Betahistine
🔹 4. Symptomatic Treatment
- Antihistamines (meclizine)
- Antiemetics
⚠️ Use short-term only (avoid delaying compensation)
🧠 Vestibular Rehabilitation
- Balance training
- Gaze stabilization exercises
- Adaptation techniques
👉 Promotes central compensation
🌿 Complementary Measures
- Hydration
- Stress reduction
- Avoid sudden head movements
⚠️ Not a substitute for medical treatment
⚠️ Complications
- Falls and injury
- Chronic imbalance
- Anxiety disorders
❓ FAQ (SEO Optimized)
🔹 What is the most common cause of vertigo?
BPPV is the most frequent cause.
🔹 How long does vertigo last?
Depends on cause: seconds (BPPV) to days (neuritis).
🔹 Is vertigo dangerous?
Usually benign, but central causes can be serious.
🔹 When should I worry about vertigo?
If accompanied by neurological symptoms.
🔹 Can vertigo go away on its own?
Yes, many cases resolve spontaneously.
🔹 What is the best treatment?
Depends on the underlying cause.
🔹 Does stress trigger vertigo?
Yes, especially in vestibular migraine.
🔹 Can exercises help vertigo?
Yes, vestibular rehabilitation is highly effective.
