Vertigos
The vertigos are uncomfortable, worrying the
sensation that can feel like rotating, unsteadiness, or I am annoying.
Whereas still she is stopped, some people feel as if the
world is rotating around her, doing the sensation to him nauseated.
Whereas she walks, the sensation some people its knees goes
wobbly, and it feels unstable and unstable. Immediately after
being unemployed for above, some people shake themselves, posteriora
part of the right of the drop down in the chair feels sometimes as if
its head is swimming, and. After being unemployed by awhile,
some people feel light-headed. All this people can say that they
feel been annoying.
Because so many diverse sensations can be described like
vertigos, the doctors often try to put vertigos in categories.
This people of the aid of the categories are understood when she
speaks of vertigos. Four categories are used generally.
The vertigo is a sensation of the movement when there is
no movement. It is often described like rotating. The
vertigo is what some has people immediately after it mounts in a
merry-go-round. It briefly feels as if she still is moving,
later she even has both feet planted firmly in the Earth. People
with vertigo can feel that she is moving or who the environs are
moving whereas still it continues having. The vertigo happens
generally when a person is being stopped. But position happens
sometimes whereas a person is seating, lying down, or changing.
People with vertigo can also have nausea, to times with
vomiting, and abnormal unequal movements del eye (nistagma).
Dysequilibrium is a sense of unsteadiness or the loss of
balance that implies the legs or the trunk. Dysequilibrium can
happen whereas a person is being stopped or is walking.
I am annoying is a sensation that desmayar itself can
happen at the next moments. I am annoying happens generally when
a person rises quickly after seating or to lie down by awhile.
The mixed vertigos are a miscelánea category. They
refer the vertigos that do not fit carefully in one of the other three
categories.
The categories look like to work enough or for the
vertigos that last less than a month (temporary or acute vertigos).
But for the vertigos that last more than a month (persistent or
chronic vertigos), the categories begin to guard meetings. For
example, the vertigos can look like as I am annoying and vertigo in
the same time. Or the vertigos can look like to change from a
category to another one in a certain term. Older people have
chronic vertigos generally, so the categories are less beneficial.
See the problems of the table that can contribute to the
vertigos.
Causes
The vertigos can happen when the brain obtains
incorrect information or that it is in conflict on the position of the
body with respect to the environs and to the movements of the body.
Several parts of the body provide this information. They
include the eyes, a structure in the internal oido one (called the
labyrinth to vestibular), and the nerves that take the information of
great joints (in the neck, the hips, the knees, and the ankles) to the
brain. The brain constantly uses the information of these pieces
of body to direct to the muscle activities and the joints to maintain
balance and the stability. When the body cannot maintain the
balance and the stability, the vertigos happen sometimes.
To age can cause some of the implied pieces of body in
balance less well to the function. But the effect is not enough
to cause vertigos unless a person also has a disorder or takes a drug
that adds to the effect. To have problems with several of the
implied pieces of body in balance is a cause common of the vertigos in
older people. For example, a person can have problems of the
vision, the problems (vestibulares) of the internal oido one, and the
damages or arthritis (that of the nerve can interfere with the
information sent of the joints to the brain). In such cases, the
brain is not able enough information to maintain the balance and the
stability.
Many disorders can cause vertigos. Between older
people the common causes include two disorders of the internal oido
one: benign positional vertigo and disease of Meniere.
- Benign positional vertigo: The vertigo
happens when the head moves—for example, when a person
lies down, rises, it upsets in bed, or it watches for above. The
benign positional vertigo becomes when the particles that are
distributed normally uniformly in the full channels of flowed of the
oido group of internal the meetings.
- Disease of Meniere: The vertigo is
accompanied generally loss of low ear and rugiendo or sounding in the
ears (humming). The disease of Meniere is caused by excess of
liquid in the internal oido one.
Some disorders cause I am only annoying during or after
certain activities. For example, an excessive fall in the
arterial pressure after being unemployed upon quickly (hypotension
orthostatic) or after eating a food (postprandial hypotension) can do
that people feel light-headed after those activities. In both
cases, the brain does not obtain enough blood because the arterial
pressure is too low.
Some disorders tend to cause temporary vertigos. For
example, a person who has an attack of the heart can feel been
annoying (generally light-headed) and to suddenly continue feeling
that way by some days to some weeks. Whereas the heart cures,
the sensation leaves. With other disorders, how long the
vertigos will last is uncertain. For example, if a person with
diabetes develops dysequilibrium, they can enter a month far, or can
last for a course of the life (although its severity can vary).
The depression causes vertigos sometimes. People press
themselves that she can lose confidence in his legal capacity
reciprocally with his environs. It can then feel unstable or
light-headed.
A number under the cells of red blood (anemia), a low or
high level of the sugar (glucose), or a level under vitamin B12 can contribute to the vertigos.
A thyroid gland underactive (hipotiroidismo) can cause vertigos.
The vertigos can also be a temporary drug indirect effect
certain, including many taken for high the arterial tension.
This type of vertigos often leaves after a person takes the drug
for one week or two. Antihistamine and the aids of the dream,
including nonprescription, can contribute to the vertigos.
Certain situations can cause temporary vertigos in healthy
people. For example, giving return around or being unemployed
for above can very quickly cause a brief period of the vertigos.
Bifocals that uses can cause vertigos when a person goes under
the stairs or watches down.
Diagnosis
Populate who must disclose the vertigos to him of
the experience to their doctor. A doctor tries to identify what
is causing the vertigos and if the vertigos fit in a specific
category, as vertigo. In order to do therefore, the doctor
requests that the person describes the vertigos. For example,
the doctor asks if the vertigos are accompanied by other symptoms,
such as nausea. The doctor also asks how long the vertigos have
been present. If the vertigos have been present for less than a
month, the doctor can ask if the person began to take some new
prescription or drugs nonprescription and if the meterings of some
drugs have changed recently. If the vertigos have lasted more
than a month, the doctor verifies to know if there are certain
disorders that can cause the vertigos.
The doctor makes a physical examinación. The
hearing test to help itself to determine if an ear is working
incorrectly. If an ear hears better than the other, the person
can have a disorder of the internal oido one, that can contribute to
the vertigos. The vision is proven, and the eyes are verified to
know if there are specific problems that can limit the vision, as
cataracts.
Sometimes the doctor observes the eyes for the abnormal
movements that move of a pull (nistagma), which they can indicate a
disorder of the internal oido one. The doctor can make a simple
maneuver, call the maneuver of Hallpike. For this maneuver, the
person feels in a table. The doctor puts quickly to person down
with the head of the person who hangs on the edge of the table.
In the same movement, the doctor gives to return to the main
person the a the left right or. If the vertigos are caused by a
disorder of the internal oido one, the maneuver of Hallpike can
produce nistagma and vertigos quickly.
The doctor uses estetoscopio to verify the index, the
rate, and the sound of the beat of the heart. The arterial
pressure is moderate after the person has itself been laying down by
near 5 minutes and immediately after the person she is stopped for
above. One is moderate sometimes again after 3 minutes.
These measures help to determine if the cause of the vertigos is
hypotension orthostatic.
The doctor verifies some aspects of the function of the
brain and the nerve, particularly of the senses of the position and
the balance. For example, a person can still be requested to be
shutdown with the been on awares, then with the closed eyes. If
the person shakes itself more than awaited, the vertigos can be caused
by a disorder of the internal oido one, a disorder of the brain, or a
problem with the capacity of the body to send the information of the
great joints to the brain.
The blood analyses can be done. Typically, the
number of the cells of red blood and the levels of the sugar, vitamin
B12, and hormones of thyroid is
moderate.
If the evidence suggests a disorder of the heart,
specially an abnormal rate of the heart, electrocardiography (ECG) can
be made to register the electrical activity of the heart. The
person can be requested to use a small device, with batteries of ECG
(monitor of Holter) by 1 or 2 days. If the evidence suggests a
disorder of the brain, tomography computed (CT) or the projection of
image of magnetic resonance (MRI) can be made to obtain the images of
the brain.
Treatment and prevention
The goals of the treatment are that they correct
or that they control possible causes of the vertigos and that they
allow people to prevent or to control vertigos so that they can make
activities surely daily.
The vertigos can sometimes be cured. For example, if
a drug is causing them, the drug can be stopped and be changed to the
something more. If the cause is benign positional vertigo, the
maneuver of Epley can provide a treatment. The maneuver of Epley
is resembled the maneuver of Hallpike, that is used for the diagnosis.
If I am annoying persistent it relates to the episodes of the
arterial tension loss that happen when a person is stopped for above
or after a person eats, to use the averages of the aid (average of the
compression) can help. The drugs such as fludrocortisone and
midodrine can be used.
The maneuver of Epley sees the figure: A possible
treatment for the vertigo?
The people who have experienced vertigos do not have to
take the drugs nonprescription that can contribute to the vertigos,
such as antihistamine or aids of the dream. The antihistamine
ones can make worse vertigos in older people, although the low doses
of these drugs help some adults younger than they have persistent
vertigo.
If the vertigos persist in spite of the treatment, the
people can learn how to avoid the movements that tend to drive
vertigos. The examples are watching for above, they are reaching
after above, or they are bending down. A form to avoid these
movements is to store to articles of the house between the waist and
the level of the eye. Rising slowly after seating or to lie down
by awhile can help. The squeeze of the hands and to double the
feet helps sometimes, specially if the vertigos feel as I am annoying.
Perspective
For some people, the vertigos leave or diminish
without the treatment. For others, the vertigos only leave or
diminish after the cause is corrected. For other immovable ones,
the vertigos, equal when they are treated, last per months or years.
Nevertheless, most of this people it can do in front and
continue daily activities, specially when the treatment controls the
vertigos to a certain degree.
