Overview

Vertigo can be described as subjection sensation of movement such as spinning, turning or whirling of patients or respective surroundings. Vertigo is a symptom not a diagnosis. It results from dysfunction either in the vestibular or central nervous system ; thus can be classified as peripheral or central vertigo respectively. Some conditions can present with subjective feeling of dizziness without vertigo hence named as pseudo-vertigo. Most children or adolescents have secondary vertigo as a result of various conditions such as otitis media, benign paroxysmal vertigo, head trauma or any CNS infection. Successful management of vertigo usually consists of identifying the root cause and specifically targeting the underlying condition.

Causes

Life-Threatening Causes	Common	Misc.
Head trauma (labyrinthine concussion, whiplash syndrome, basilar artery migraine) CNS infection Intake of specific Poison Drug Adverse Effect Stroke Brain tumor Congenital ear abnormalities (Mondini's malformation, enlarged vestibular aqueduct)	Binocular vision abnormalities Benign paroxysmal vertigo of childhood Vestibular neuritis Migraine Somatoform vertigo   Motion sickness Otitis media complicated by labyrinthitis	Mastoiditis Meniere disease Middle ear trauma Multiple sclerosis Perilymph fistula Ramsay Hunt syndrome Seizure

FIRE: Focused Initial Rapid Evaluation

Identify cardinal findings that increase the pretest probability of vertigo (at least 2 of the following) ❑ Physical sensation of spinning or moving ❑ Nystagmus ❑ Nausea with or without vomiting

Yes

No

History of Head Trauma

Pseudovertigo

Findings of Abnormal CT-Scan/MRI

Altered level of Consciousness

YES

NO

YES

NO

Fracture of Temoral Bone,enlarged vestibular aqueduct

Post-concussion syndrome, Post traumatic migraine

If History of fever , Consider CNS infections such as meningitis and encephalitis If abnormal CT-Scan Brain or MRI, consider Migraine, Drug Overdosingm or Post-ictal state

Perform Otoscopy
