VERTIGO
Vertigo is a feeling of dizziness. Person with vertigo often feel that their body or the things around them are moving or spinning when they are standing. It can be caused by a problem with the balance mechanisms of the inner ear, a problem with the nerves that connect the brain to the middle ear, or a problem with brain cause a head injury. The most frequent cause of vertigo is there is a problem with the balance mechanisms of the inner ear. When the virus or bacterical infected the inflammation of the labyrinth (a system of canals and cavities within the inner ear which gives us our sense of balance), such as common cold or flu virus that spread to the labyrinth, or when the crystal of vestibular labyrinth, inside the ear, become dislodged and move in to the one of semicircular canal, it will make the patient suddenly get the feeling of vertigo. A problem with the nerves that connect the brain to the middle ear is also the cause of vertigo. When a person gets vestibular neuritis (inflammation of the vestibular – the nerve running to the vestibule), it will destroy the collaboration between the semicircular canals and the brain work to control the body balance and he will get the feeling of vertigo. The other cause of vertigo is there is a problem with brain caused a head injury. Some people who get a head injury, because of an accident or a strong earth quake, most of them suddenly feel that all the things around them moving or spinning. The sudden sensation can occur many times a day. It occurs because the head injury destroys the balance nerve in their brain. Many things can cause vertigo (a dizziness feeling that makes people feel that their body or their surrounding are moving or spinning). But the three most frequent causes of vertigo are a problem with the balance mechanisms of the inner ear, a problem with the nerves that connect the brain to the middle ear, or a problem with brain cause a head injury.
