Simply put, vertigo is a kind of dizziness caused by problems in the brain or inner ear.
What is Vertigo?
When the world seems like it has started to spin, even though you aren’t moving, you may be suffering from an episode of vertigo.
Symptoms of Vertigo
This spinning sensation can be very disconcerting, and can lead to the following symptoms:
- Excessive sweating
- Abnormal eye movements
Types of Vertigo
There are two main forms of vertigo:
- Peripheral vertigo: It refers to a condition caused by a problem with the inner ear (vestibular labyrinth region), and there are a number of illnesses and afflictions that can cause this, including benign paroxysmal positional vertigo, as well as Meniere’s disease, in addition to smoking, diabetes, high blood pressure and certain medications. Furthermore, something as simple as cold, congested sinuses, or the flu can also affect the inner ear pressure and result in feelings of dizziness.
- Central vertigo: This refers to an issue with the balance control centers of the nervous system. This is most commonly caused by a lesion to the cerebellum or brainstem, and the symptoms can be far more severe. Unlike the peripheral type, there is less visual deception or nausea, but even more serious balance issues, meaning that some people suffering from this form are completely unable to stand or walk. A number of other factors can cause this sort of immobility, aside from a brain lesion, including migraine headaches, spine disorders, or multiple sclerosis, among others.
Note: Peripheral symptoms seem to pass more quickly, sometimes within a few seconds or minutes, but central vertigo can be much more long-lasting.
