So what triggered the leap from hearing loss to incapacitating dizziness in Miller's case? The etiology is unknown, Miller says, pointing to the possibility of a virus or inner-ear inflammation. Tumors are another cause, says Nevin, along with specific conditions such as Meniere's disease or benign paroxysmal positional vertigo, the latter of which is the most common. In BPPV, which is diagnosed with a simple clinical test, particles in the inner ear dislodge and cause the spinning sensation when one rolls over in bed or bends. I can't remove the particles, but I can help them go back in place, says Nevin.
As of today's date, the world population is estimated by the United States Census Bureau to be 7.496 billion. The US Census Bureau estimates the 7 billion number was surpassed on 12 March 2012.
That will keep us as the third most populous country on the planet, behind only China (1.35 billion) and India (1.23 billion). Overall, the world population will top 7.1 billion at the start of 2014. The precise figure â 317,297,938 â will mark an increase of 2,218,622 people in the 365 days since 2012 passed into 2013.
