Know Vertigo, Causes and How to Overcome It....


      
There are a few tips to get rid of vertigo. Vertigo is a symptom of a medical condition characterized by the sensation of  moving around in space or  having objects move around a person ; tends to come in attacks;if severe,accompanied  by nausea and vomiting.




Causes of Vertigo

 There are a number of different causes of vertigo. Vertigo can be defined based upon whether the cause is peripheral or central.
 Central causes of vertigo arise in the brain or spinal cord while peripheral vertigo is due to a problem within the inner ear.



                                 



Brain or sensory nerve disturbance:


Central vertigo

  is a term that collects together the central nervous system causes - involving a disturbance to one of the following two areas:
  • The parts of the brain (brainstem and cerebellum) that deal with interaction between the senses of vision and balance, or
  • Sensory messages to and from the thalamus part of the brain.
The central nervous system regulate a sense of balance. Disruption by diseases of the central nervous system such as multiple sclerosis, tumors, neck damage, or stroke can cause vertigo

Uncommon causes are stroke and transient ischemic attack, cerebellar brain tumor, acoustic neuroma (a non-cancerous growth on the acoustic nerve in the brain) and multiple sclerosis


Inner ear disturbance:
 
 unilateral vestibular disorder:[UVD]
 
Peripheral vertigo 

 is a term that collects together the inner ear causes.

The labyrinth of the inner ear has tiny organs that enable messages to be sent to the brain in response to gravity. By telling our brains when there is movement from the vertical position, we are able to keep our balance, maintain equilibrium.
Disturbance to this system therefore produces vertigo and can be created by inflammation among other causes. Viral infection is behind the inflammation seen in the following two conditions:
  • Labyrinthitis - this is inflammation of the inner ear labyrinth and vestibular nerve (the nerve responsible for encoding the body's motion and position
  • Vestibular neuronitis - this is thought to be due to inflammation of the vestibular nerve. an acute infection with prolonged attack of symptoms,persisting for several days or weeks;caused by viral or bacterial infection.
    Infections such as colds, flu, or other inflammation can affect the inner ear and cause vertigo.
  • Ménière's disease
        This form of vertigo is thought to be caused by high pressure of a fluid in a compartment of the inner ear (a swelling that is also known as endolymphatic hydrops).

As well as infection, Meniere's disease can result from metabolic and immune disorders.

 recurrent and usuallay progressive vestibular disease;episodic attacks may last from minutes to several hours with severe symptoms ;usually associated with tinnitus ,deafness,sensation of pressure/fullness with in ear;etiology:unknown,edema of membranous labyrinth is a consistent finding



 
Benign paroxysmal positional vertigo

Benign positional vertigo is due to a disturbance within the inner ear. The inner ear has fluid-filled tubes called semicircular canals. The canals are very sensitive to movement of the fluid, which occurs as you change position. The fluid movement allows your brain to interpret your body's position and maintain your balance.

Benign positional vertigo develops when a small piece of bone-like calcium breaks free and floats within the tube of the inner ear. This sends the brain confusing messages about your body's position.




                             


Benign paroxysmal positional vertigo (BPPV) is the most common disorder of the inner ear’s vestibular system, which is a vital part of maintaining balance. BPPV is benign, meaning that it is not life-threatening nor generally progressive. BPPV produces a sensation of spinning called vertigo that is both paroxysmal and positional, meaning it occurs suddenly and with a change in head position. - See more at: http://vestibular.org/understanding-vestibular-disorders/types-vestibular-disorders/benign-paroxysmal-positional-vertigo#sthash.ipE9F7RB.dpuf
