9 Medications, including frusemide, salicylates and antihypertensive agents, can affect the vestibular system, which in turn causes vertigo. 8 Loud noises can precipitate vertigo in patients with peripheral causes in a phenomenon called Tullio phenomenon. Patients who experience anxiety or panic attacks can have vertigo as a result of hyperventilation. Vertigo can be triggered by a change in the position of the head, recent upper respiratory tract infection (URTI), stress or trauma. Peripheral pathology is associated with symptoms of nausea, vomiting and hearing loss. Risk factors for vascular disease, including smoking, diabetes, obesity, hypertension and hypercholesterolaemia, need to be assessed to rule out CVAs, which can lead to vertigo from ischemia or infarction. It may be difficult to distinguish between central and peripheral causes in patients who present with vertigo as their only symptom. Central causes are suspected if the patient presents with associated neurological symptoms such as weakness, dysarthria, sensory changes, ataxia or confusion. More serious central causes, such as cerebrovascular accidents (CVAs), tumours and multiple sclerosis (MS), need to be considered. Once the diagnosis of vertigo is determined, this needs to be differentiated into a central or peripheral subtype. It is important to differentiate vertigo from other non-rotational forms of dizziness. Often, patients presenting with dizziness are unable to describe the sensation and can be vague, particularly if it is the initial presentation. Any disruption of this pathway can lead to vertigo. These send impulses to the brain stem and cerebellum to control balance. When the head tilts, receptors on the ipsilateral ear are stimulated and receptors in the contralateral ear are inhibited. Receptors in the semicircular canals respond to the position of the head. These cells control vertical and non-rotational movements. 6 The utricle and saccule contain hair cells embedded in calcium carbonate crystals. The vestibular apparatus of the inner ear consists of three semicircular canals, and two otolith organs called the utricle and the saccule. 5 This in turn receives input from the visual pathway, proprioception and inner ear.
Conversely, symptoms arising in the inner ear or from the vestibular nerve are classified as peripheral.īalance is controlled by the cerebellum, which receives input from the vestibular nuclei in the brain stem. 4 Vestibular symptoms originating from pathology in the cerebellum or brain stem are classified into the central type.
Vertigo can be classified as central or peripheral on the basis of vestibular symptom pathology. presyncope (sensation of feeling faint).light-headedness (sensation of giddiness) 3.Dizziness can be classified into four groups: This sensation can be confused with dizziness, which is a non-specific term, so an adequate history is required to differentiate this symptom. 2 Often patients describe a ‘spinning’ sensation of either their body or their surroundings. 1 Classically, vertigo presents as a sensation of movement of the environment around the patient.
