Vestibular disorders include:

Acoustic neuroma
Rare benign tumour on the nerve that runs from the inner ear to the brain. Main symptoms are hearing loss and tinnitus (ringing in the ears) as well as dizziness and balance problems.

Age-related dizziness and imbalance
One of the most common problems of older people - has many overlapping causes. Much can be done to treat and manage it.

Autoimmune inner ear disease (AIED)
Happens when the immune system attacks the inner ear. Often causes sensorineural hearing loss as well as balance problems. Uncommon.

Benign paroxysmal positional vertigo (BPPV)
Key symptom of this common and treatable condition is repeated, brief spells of vertigo (spinning sensation) brought on by a change in head position. Usually treatable by guided head movements.

Bilateral vestibulopathy (BVP)
Damage to the balance parts of both inner ears. Causes imbalance, unsteady gait, and "jumpy vision" with head movement.

CANVAS syndrome
Stands for cerebellar ataxia with neuropathy and vestibular areflexia. This rare neurological syndrome affects balance.

Cervicogenic dizziness
Related to a neck problem. Frequent symptoms include episodes of dizziness, lightheadedness, and unsteadiness.

Childhood dizziness and imbalance
Fairly common in children. Most problems are temporary and easy to treat. Longer-lasting conditions are often accompanied by developmental delays.

Cholesteatoma
Rare, slow-growing, benign growth in the middle ear. If not treated, can eventually destroy parts of the inner ear needed for hearing and balance.

Concussion
All concussions are traumatic brain injuries. Frequent symptoms include headaches, dizziness, nausea, and difficulty concentrating.

Enlarged vestibular aqueduct
Larger-than-normal tube between the inner ear and deep in the skull. Most often affects young people. Symptoms include sensorineural hearing loss as well as balance problems.

Labyrinthine infarction
Serious type of small stroke. Warning signs include sudden hearing loss in one ear, dizziness, and/or loss of balance. Increases risk for a larger stroke. Call 911 or other emergency services.

Labyrinthitis
Inflammation of the inner ear, most often caused by a virus. Symptoms include severe vertigo (spinning sensation), usually with nausea/vomiting, as well as some hearing loss.

Mal de débarquement syndrome (MdDS)
Usually triggered by a long trip at sea. Main symptoms are constant feelings of movement lasting for weeks, months, or even years.

Ménière's disease
Hallmark symptom of this chronic, progressive condition is sudden attacks of vertigo (spinning sensation), usually lasting several hours.

Motion and cyber sickness
Nausea or discomfort triggered by exposure to real or virtual movement. Many strategies can reduce the symptoms.

Otosclerosis
One of the most common causes of conductive hearing loss in young adults. Symptoms may include tinnitus, dizziness, and balance problems.

Perilymph fistula
Brings on sudden or progressive hearing loss in one ear as well as episodes of vertigo (spinning sensation). Rare condition.

Persistent postural-perceptual dizziness (PPPD)
Common cause of long-lasting dizziness and feelings of unsteadiness. Anxiety often develops about things that trigger dizziness.

Ramsay Hunt syndrome (RHS)
Shingles outbreak affecting a facial nerve near one ear. Usually affects older people. Sometimes causes vertigo (spinning sensation). Rare condition.

Secondary endolymphatic hydrops (SEH)
Build-up of fluid in inner ear. Associated with spells of vertigo (spinning sensation) and hearing loss that comes and goes.

Semicircular canal dehiscence (SCD)
Rare condition caused by a hole in part of the inner ear. Can bring on both hearing and balance symptoms. People with SCD often hear sounds from inside their own bodies.

Vestibular migraine
Common cause of repeated attacks of dizziness and other vestibular symptoms, often without headache pain. Frequently undiagnosed and undertreated.

Vestibular neuritis
Problem with the vestibular nerve. Causes a single sudden, severe attack of dizziness, usually with nausea and vomiting. Hearing loss is not a symptom.

Vestibular paroxysmia
Damage or pressure on the vestibular nerve causes short, recurring attacks of vertigo (spinning sensation). Uncommon chronic disorder.

Vestibular toxicity
Temporary or permanent damage to the balance system from some drugs and chemicals. Fortunately, rare.

Visually induced dizziness
Umbrella term for a group of symptoms resulting from some vestibular disorders. Often brought on by looking at complex patterns or movement.
