Signs of positional vertigo
Dizziness: Episodes of dizziness with certain head movements are frequently found in the cases of positional vertigo.
Spinning sensation: Positional vertigo gives the sensation of spinning while tilting the head down, lying down, or getting up. A person feels a sudden sensation that the surrounding is spinning. Positional vertigo is usually triggered by specific changes in the position of the head.
Loss of balance: A person experiences loss of balance in positional vertigo which is one of the most typical symptoms of positional vertigo. Loss of balance is due to dizziness and spinning sensation that makes it difficult for the person to judge his or her surrounding well, affecting the sense of balance.
Vomiting: Positional vertigo caused by inflammation inside the ear can cause symptoms of vomiting. However, frequent vomiting can cause dehydration. One must consult a doctor if s/he feels the persistent dizziness and vomiting is because of Positional vertigo.
Hearing loss: Inflammation in ears can further cause problem in the semicircular canal and can trigger hearing loss. In positional vertigo, the inner ear is responsible for handling signals, if these are not transmitted properly, it causes hearing loss.
Blurred vision: One symptom of positional vertigo is rapid eye movement. As the jerky movements subside, eyes drift slowly back to center because of positional vertigo and can cause blurred, double or loss of vision. A person suffering from positional vertigo may feel that the surrounding is moving. This may cause blurry vision.
Causes of positional vertigo
Positional vertigo occurs because of disturbance inside the inner ear. Semicircular canals are the tubes inside the ears carrying fluid that moves with the change of the body’s position. These semicircular canals are distinctly delicate. Positional vertigo develops when small crystals of calcium carbonate in other areas of the ear break free inside the semicircular canals. It makes the brain initiate complicated messages about the body’s position. Positional vertigo can also cause migraines.
Causes of positional vertigo include:
3. Blurred vision
6. Rotary nystagmus
7. Loss of balance

It includes tilting of the head in different positions so that calcium carbonate moves to the different area of inner ears.
Dizziness associated with positional vertigo can be managed by taking a few precautionary methods. Beware of your surroundings and place at all times. Try to go into risk-free position or place when feeling dizzy to prevent falling and injuries. Take a seat when feeling drowsy to prevent falling.

1. Sedative-hypnotics which are sleeping aids
2. Anticholinergics which prevents the brain sending wrong messages
However, medications are not the best way of treating positional vertigo.
Surgical treatments such as semicircular canal occlusion can be done for treating positional vertigo. Surgeries carries a risks of neurosurgical procedures. Neurosurgical procedures can cause bleeding in the brain, brain swelling, strokes or coma. Therefore, surgeries are reserved for the last stage of positional vertigo.
