Have you ever felt that the room was spinning, even when you were standing or sitting still? This sensation, known as vertigo, can affect balance, walking, and everyday activities. While vertigo is often linked to inner-ear problems, it can sometimes indicate a neurological condition involving the brain. Understanding the difference between central and peripheral vertigo helps specialists identify the possible cause and recommend appropriate treatment.
Vertigo is a sensation of spinning, tilting, or movement when no actual movement is occurring. It may be accompanied by nausea, imbalance, dizziness, or difficulty walking. Vertigo is a symptom rather than a disease, and its cause can range from relatively common inner-ear disorders to serious neurological conditions.
Peripheral vertigo originates in the vestibular system of the inner ear or the vestibular nerve, which carries balance information to the brain. It is the more common type of vertigo.
Common causes include:
Benign Paroxysmal Positional Vertigo (BPPV): Brief episodes triggered by specific head movements.
Vestibular neuritis: Inflammation affecting the vestibular nerve, often causing sudden, prolonged vertigo.
Labyrinthitis: Inflammation of the inner ear that may cause vertigo and hearing symptoms.
Ménière’s disease: Episodes of vertigo associated with fluctuating hearing loss, tinnitus, or ear fullness.
Peripheral vertigo often causes intense spinning sensations, nausea, and sometimes hearing changes or ringing in the ears. Symptoms may worsen with head movement, depending on the underlying condition.
Central vertigo occurs when a condition affects the brain’s balance-processing pathways, particularly areas of the brainstem or cerebellum.
Possible causes include:
Stroke affecting the brainstem or cerebellum
Multiple sclerosis
Certain brain tumours
Other neurological disorders affecting balance pathways
Central vertigo may cause persistent imbalance, difficulty coordinating movements, unusual eye movements, double vision, or problems walking. Hearing symptoms are less characteristic, although their presence or absence cannot reliably establish the cause.
Importantly, a stroke can sometimes present primarily with dizziness or vertigo, even without obvious weakness or speech difficulties.
Specialists assess the patient’s medical history, symptom pattern, associated features, and examination findings.
1. Symptom history: Doctors ask when the vertigo started, how long episodes last, whether head movements trigger them, and whether hearing changes or neurological symptoms occur.
2. Eye movement examination: Abnormal eye movements, called nystagmus, can provide important clues. Certain patterns may suggest an inner-ear disorder, while others raise concern for a central cause.
3. Balance and neurological assessment: Specialists evaluate walking, coordination, limb strength, sensation, and other neurological functions.
4. Vestibular testing: Depending on the suspected cause, tests may include positional manoeuvres, hearing tests, or specialised assessments of inner-ear function.
5. Brain imaging: MRI or other imaging may be necessary when a central neurological cause is suspected. A normal early scan does not always exclude a stroke, so clinical assessment remains important.
No single symptom or test reliably distinguishes every case. The findings must be interpreted together by an appropriately trained clinician.
Seek emergency medical care immediately if vertigo begins suddenly with difficulty walking, double vision, slurred speech, facial drooping, weakness, numbness, or a severe, unusual headache. These may indicate a stroke or another serious neurological condition. Do not wait for symptoms to disappear.
Persistent, recurrent, or unexplained vertigo also deserves medical evaluation, especially when accompanied by hearing changes or frequent falls.
Treatment depends on the underlying cause. Peripheral vertigo may improve with repositioning manoeuvres, medication for selected symptoms, or vestibular rehabilitation. Central vertigo requires management of the underlying neurological condition and may also benefit from rehabilitation.
At NeuroENT Clinic Delhi, appropriate ENT and neurological assessment can help guide the evaluation of dizziness and balance disorders.
