Vertigo, often referred to as a head rush, is a major symptom of a balance disorder. Vertigo is when an individual experiences spinning or whirling when there is no external stimuli to cause this feeling. This sense of movement that is a characteristic of vertigo should not be confused with dizziness. When someone is dizzy, they experience blurry vision and disorientation. With vertigo, there is a distinct feeling of movement. When an individual closes their eyes and experiences moving, this is referred to as subjective vertigo. Vertigo can also be an indicator of a serious underlying condition such as a tumor. There are two types of vertigo: peripheral vertigo and central vertigo.
Vertigo is caused by an infection or disruption in the inner ear (especially the portion that controls balance), damage to the brain, or damage to the nerves that connect the ear to the brain. A main cause of vertigo is benign paroxysmal positional vertigo. Central vertigo is frequently caused by tumors, migraines, or multiple sclerosis. Vertigo can be a symptom of other, more serious medical problems.
The extremity of the feeling varies among people. Often, nausea, vomiting are experienced with vertigo. A person who suffers from severe vertigo will have difficulty standing and walking. Peripheral vertigo is often less severe though its symptoms are more intense. This type of vertigo is associated with tinnitus. Central vertigo is more constant.
