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 a 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
- Various causes of vertigo in the pediatric population are given in the table below:[1]

FIRE: Focused Initial Rapid Evaluation
A Focused Initial Rapid Evaluation (FIRE) should be performed to identify patients in need of immediate intervention.[2]
Boxes in red signify that an urgent management is needed.
Identify cardinal findings that increase the pretest probability of vertigo (at least 2 of the following)

Complete Diagnostic Approach
A complete diagnostic approach should be carried out after a focused initial rapid evaluation is conducted and following initiation of any urgent intervention.

Gait & Gross Motor Testing
• Vestibulospinal testing – Fukuda: arms straight in front at shoulder height, vision excluded, instructed to march in place for 50 steps, in the presence of chronic peripheral vertigo the child will march slowly towards the side of the lesion – Romberg test or Tandem gait: child puts one foot in front of the other, arms at sides, vision allowed and then excluded) tests to evaluate the dorsal column• Age-appropriate gross motor (Bruininks- Oseretsky test 4-21yrs) | |||||||||||||||||||||||

Treatment
Shown below is an algorithm summarizing the treatment of vertigo according the the AAO-HNS guidelines.[3]
Patient with Established Diagnosis of Vertigo | |||||||||||||||||||||||||||||||||
Central Vertigo | Peripheral Vertigo | ||||||||||||||||||||||||||||||||
Treat according to etiology | |||||||||||||||||||||||||||||||||
Acute Treatment : Antiemetics including metoclopramide and prochlorperazine in severe cases. Vestibular sedation with medications such as meclizine, dimenhydrinate, promethazine, and diazepam may be used acutely but should not be prescribed long term.
BPPV- Epley particle repositioning maneuver. This maneuver relocates the free-floating debris from the posterior semicircular canal into the vestibule of the labyrinth. Symptomatic relief after a single treatment session is reported in 80% to 90% of patients, although 15% to 30% may have a recurrence of symptoms. The maneuver is repeated until nystagmus no longer can be elicited. Ménière disease- Salt Restriction,Diuretics,ntratympanic dexamethasone or gentamicin,Endolymphatic sac surgery Vestibular Neuritis- Methylprednisolone tapered over 3 weeks | |||||||||||||||||||||||||||||||||
Do's
- Different maneuvers can be done to reduce the intensity of vertigo.
- Epley-Maneuver : Left sided vertigo. Make the patient sit on the edge of the bed. Turn the head of patient 45 degrees to the left. Place a pillow under his shoulder. Make him lie down on his back with his head still at 45 degree angle. Wait for 30 seconds.Turn the head of patient 90 degrees to the right without raising it. Wait for another 30 seconds. Turn the head and body of the patient to right side towards the floor. Wait for another 30 seconds. Slow make the patient sit up. Reverse the instructions in case of right sided vertigo.[4]
- Semont Maneuver: Make the patient sit on the edge of the bed. Turn the head 45 degrees to the right and make him quickly lie down towards left side. Wait for 30 seconds. Now quickly move the patient to lie down on the other side of the bed. Keep his/her head at a 45 degree angle and lie for 30 seconds to look at the . Now make him/her slowly sit and wait for few minutes. Reverse this for right sided vertigo.[5]
Don'ts
- Avoid consuming fluids that have high sugar or salt content in it such as concentrated drinks and soda. These are the foods that trigger vertigo.
- Limit Caffeine intake. Caffeine has been reported to cause cell depolarization making the cells more easily excitable
- Following is the list of contraindications to canalith repositioning procedure:
- Severe carotid stenosis
- Unstable heart disease
- Severe neck disease, such as cervical spondylosis with myelopathy or advanced rheumatoid arthritis.
- Limit salt intake as it causes retention of excess fluid in the body and interferes with vestibular system.
- Processed food and meats should be avoided.
- To reduce the risk of fall because of vertigo, advise patients to get rid of loose electrical cords, clutter and slippery rugs and also advise them to wear sturdy non-slip shoes.
