is anxiety?
Anxiety is an unpleasant state of
fear that manifests externally through various symptoms and signs, and can be a
normal or exaggerated response to certain stressful world we live in, but can
also be a pathological response and produced by abnormal variety of medical and
/ or psychiatric.

and distress as equivalent terms, are not really the same, so that the first is
related more to the psychological inner feeling of discomfort and distress with
bodily outward manifestations that accompany anxiety.
How
does it manifest anxiety and what causes it?
Anxiety can occur chronically, as
a personality trait present for most of the individual's life ("GAD")
or as cut-intensive episodes. These episodes that cause feelings of impending
doom ("thanatophobia"), or fear of going crazy ("manifobia")
are the "panic attacks", "panic" or "panic attacks"
and are the "panic disorder or panic. "
The difference, therefore, between
the "generalized anxiety disorder" and "anxiety or panic" is
based on that in the first patient continually unwell, whereas panic disorder, the
subject is perfectly fine between crises. In addition, many people who suffer panic
attacks often develop a fear or dread a repetition progressive, appearing then
called "anticipatory anxiety".
As for the causes, we speak of
primary and secondary anxiety.

attacks have been unexpected, namely that have not been displayed immediately
before or during exposure to a situation that almost always causes anxiety, and
have not been triggered by situations in which the individual has been the
focus of attention of others.

of other pathology or organic factor explaining the picture.

women and usually begins between 20 and 30 years.
Some patients develop secondary
dependencies to alcohol or anxiolytic drugs.
It is often associated with
agoraphobia (fear of being in places or situations where escape is difficult
and many people concentrate.

hyperventilation (the subject breathes a very fast), it may be helpful to place
a plastic bag or glove over your nose and mouth to breathe in an atmosphere
rich in CO2. This operation will occur all over the head uncovered and provided
with plastic bag to observe and see the patient's face (may vomit or acquire a
bluish hue that can indicate a more serious).
Anxiolytic medication is useful
for cutting the crisis. Benzodiazepines are commonly used orally at low doses, Diazepam
or Clorazepam type.
