Vestibular Neuronitis
- It is an inflammation and disorder of the vestibular portion (labyrinth) of the inner ear, (like a chamber of the inner ear). This chamber helps to maintain a person's sense of balance.
- The symptoms are frequent episodes of vertigo (dizziness) accompanied by nausea. However there is no ringing in the ears, unlike Meniere's Disease, where it is present. It is caused by viruses like influenza, mumps, measels, rubella, etc.
Benign Paroxysmal Positional Vertigo:
- It is characterized by frequent episodes of positional vertigo (dizziness). These attacks are usually of short duration lasting for few seconds or minutes.
- The other symptoms are nausea, visual disturbance during attack due to rapid, involuntary movements of the eyeball. The onset of vertigo is due to change of position like tilting the head, looking up or under etc.
Perilymphatic Fistula
- Perilymphatic fistula is an abnormal opening in the bony capsules of the inner ear causing leakage of the fluid from the inner ear to the middle ear. It occurs due to a rupture in the oval window that separate the inner and the middle ear.
- The symptoms are dizziness, hear loss and imbalance. However, sensation of spinning i.e. vertigo is absent.
Bilateral Vestibulopathy:
- In this condition balance, vision and hearing is affected. Imbalance worsens in the dark or in unseen or unsure circumstances. Spinning vertigo is not present.
- Transient visual disturbances or blurring may be present. It occurs as a result of complete damage to both the ears.
Migraine
- Migraine-associated dizziness may present like Meniere's Disease. However, there is a characteristic presence of headache, generally one-sided and other symptoms like nausea, vomiting, extreme sensitivity to light and noise.
- Hearing loss and ringing in the ears is not present.
