This is the most common cause of vertigo, the sensation that you or your surroundings are spinning or moving. BPPV is caused by tiny calcium crystals that become dislodged in the inner ear, disrupting the balance signals sent to the brain.

This is an inflammation of the vestibular nerve, which connects the inner ear to the brain. It can cause sudden and severe vertigo, often accompanied by nausea and vomiting.

This is an inflammation of the labyrinth, a part of the inner ear that contains the balance organs. It can cause vertigo, hearing loss, and tinnitus (ringing in the ears).

This is a chronic condition that affects the inner ear, causing episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear.

Migraines can sometimes cause dizziness or vertigo, even without a headache. This is known as vestibular migraine.

A sudden drop in blood pressure can cause dizziness or lightheadedness, especially when you stand up too quickly (orthostatic hypotension).

Some medications can cause dizziness as a side effect, including certain antidepressants, anti-seizure medications, and blood pressure medications.

Anxiety disorders, such as panic attacks or generalized anxiety disorder, can sometimes cause dizziness or lightheadedness.

VNG assesses the function of the vestibular system and central motor function by recording and analyzing eye movements.

Neurodiagnostic Auditory Brainstem Response (ABR) is a medical test used to measure the electrical activity in the brainstem in response to sound stimuli. It is commonly used to assess hearing, particularly in individuals who are unable to participate in traditional hearing tests, such as newborns or individuals with developmental disabilities.

Vestibular Evoked Myogenic Potentials (VEMPs) are diagnostic tests used to assess the function of the vestibular system, which is responsible for balance and spatial orientation. There are two types of VEMP tests: Cervical VEMP (cVEMP) and Ocular VEMP (oVEMP). These tests measure the electrical responses generated by the muscles in response to sound or vibration stimuli, providing information about the function of different parts of the vestibular system.

Electrocochleography (EcochG) is a diagnostic test used to measure the electrical activity of the cochlea (the hearing organ in the inner ear) and the auditory nerve. It helps assess how well the inner ear and auditory nerve are functioning, and it is often used to diagnose various hearing and balance disorders, particularly conditions affecting the cochlea and the auditory pathways.

Rotational Testing Chair is a diagnostic tool used to assess the function of the vestibular system, particularly the semicircular canals of the inner ear, which are crucial for detecting rotational movements and maintaining balance. This test is part of a series of vestibular function tests and is often used to evaluate patients who experience dizziness, vertigo, or balance problems. The rotational chair test provides insight into how well the vestibular system is functioning and helps diagnose conditions affecting balance and spatial orientation.

Caloric diagnostic testing, also known as caloric testing or the caloric reflex test, is a type of medical procedure used to evaluate the function of the vestibular system, which controls balance. The test specifically assesses the function of the inner ear, particularly the semicircular canals, which are responsible for detecting head movements and maintaining balance.

CTSIB Balance Testing stands for the Clinical Test of Sensory Interaction and Balance. It’s a simple yet effective way to assess how well a person can use sensory inputs—vision, proprioception (body awareness), and vestibular function (inner ear balance system)—to maintain balance.

Tympanometry is a quick, non-invasive test that evaluates the health and function of the middle ear, particularly how well the eardrum (tympanic membrane) moves in response to changes in air pressure.

Middle Ear Acoustic Reflex Testing is a diagnostic procedure used to evaluate the function of a tiny muscle in the middle ear called the stapedius muscle. This test is part of a broader category of assessments called immittance audiometry, which helps identify problems in the middle ear, brainstem, and auditory (hearing) nerve pathways.

Otoacoustic Emissions (OAEs) are sounds generated by the inner ear (cochlea) in response to a stimulus, typically a click or tone. This test measures the function of the outer hair cells in the cochlea and is commonly used to assess hearing health—especially in newborns, children, and people who can’t complete traditional hearing tests.
