					Vestibular migraine is a neurological condition which may or may not be
characterized by headaches. But dizziness and vertigo is a very relevant
feature. Vertigo is an essential term for this migraine. It is a feeling
of circular motion or an illusion or in some cases both. A very common
condition called 'Motion sickness' can also trigger vestibular migraine.
Its symptoms are giddiness, vomiting, double vision etc. Ear sinus
(tinnitus i.e. heaviness and ringing of the ears) is also a prominent
feature under this migraine. It is identified by acute sensitivity to any
movement, nausea, phonophobia (a condition in which there is sensitivity
to loud sounds) and photophobia (extreme sensitivity to light). The
person is able to walk with great difficulty as it happens due to
constant dizziness. Effect lasts until 24 hours. It is generally
painless, but causes "aura" or visual disruptions characterized by blind
spots i.e. presence of a black spot near or the centre. According to NHF-
National Headache Foundation, this migraine occurs in the ratio of 3:1
with percentage occurring more in men. It can be genetic and can afflict
several members of the family at a time.The condition may not be detected
even on MRI scan and the reason behind it is unknown. It affects the
vestibular nuclei present in the brainstem. Also it can be credited to
irregular, unwanted change in the flow of blood, endocrine swings and
constriction and expansion of blood vessels. Hypertension or over anxiety
is assumed to be the cause behind this migraine and further studies show
that this is co-related, i.e. anxiety causes the migraine and vice-
versa.An important classification of vestibular migraine is the Menier's
Disease. It is the disorder of the ear that affects hearing and
equilibrium. Its symptoms are synonymous with vestibular migraine. In
addition to this there can be progressive hearing loss. Of course, it
varies from person-to-person depending on age, environment and other such
factors. These symptoms may last up to two weeks.To retrograde the effect
of vestibular migraine beta-blockers and antidepressants like
amitriptyline is used. They work their way to the Central Nervous System
by working within and out of the system. It relieves the influenced part
of CNS from duress (can be psychological) and dizziness. Full recovery
has not been observed until now but there is recovery until 30%.First of
all, it is difficult to diagnose, and once it is diagnosed, it includes
history of phases of least to average severity of the migraine, motion
sensitivity, environment changes, and hallucinations.One can take care of
this by himself if he avoids all types of bad vices-smoking, consuming
alcohol, abstains from unhealthy foods such as canned foods, readymade
'diet foods', high saturated fat content food, supplements with regular
intake of fluids.Medication includes sedatives and of course aspirin for
its property of providing immediate relief, then there are nasal drops
and antiepileptic, antidepressant drugs. These are generally used in
advanced stages.
