Anxiety is an unpleasant state of inner turmoil, often accompanied by nervous behavior, such as pacing back and forth,
somatic complaints and
rumination. It is the subjectively unpleasant feelings of dread over something unlikely to happen, such as
the feeling of imminent death Anxiety is not the same as
fear, which is felt about something realistically intimidating or dangerous and is an appropriate response to a perceived threat;
anxiety is a feeling of fear, worry, and uneasiness, usually
generalized and unfocused as an overreaction to a situation that is only
subjectively seen as menacing.
It is often accompanied by restlessness, fatigue, problems in
concentration, and muscular tension. Anxiety is not considered to be a
normal reaction to a perceived
stressor although many feel it occasionally.
Causes
Anxiety risk factors include family history (e.g. of anxiety)
and parenting factors including parental rejection, lack of parental
warmth, high hostility, harsh discipline, high maternal negative affect,
anxious childrearing, modelling of dysfunctional and drug-abusing
behaviour, and child abuse (emotional, physical and sexual).
Other contextual factors that are thought to contribute to anxiety
include gender socialization and learning experiences. In particular,
learning mastery (the degree to which people perceive their lives to be
under their own control) and instrumentality, which includes such traits
as self-confidence, independence, and competitiveness fully mediate the
relation between gender and anxiety. That is, though gender differences
in anxiety exist, with higher levels of anxiety in women compared to
men, gender socialization and learning mastery explain these gender
differences

Research has demonstrated the ways in which facial prominence in
photographic images differs between men and women. More specifically, in
official online photographs of politicians around the world, women's
faces are less prominent than men's. Interestingly enough, the
difference in these images actually tended to be greater in cultures
with greater institutional gender equality.
An
evolutionary psychology explanation is that increased anxiety serves the purpose of increased
vigilance
regarding potential threats in the environment as well as increased
tendency to take proactive actions regarding such possible threats. This
may cause
false positive
reactions but an individual suffering from anxiety may also avoid real
threats. This may explain why anxious people are less likely to die due
to accidents.
Neural circuitry involving the
amygdala and
hippocampus is thought to underlie anxiety.
When people are confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes,
PET-scans show increased bloodflow in the
amygdala
In these studies, the participants also reported moderate anxiety. This
might indicate that anxiety is a protective mechanism designed to
prevent the organism from engaging in potentially harmful behaviors
Treatments
There are many ways to treat anxiety. Cognitive behavioral therapy and medication are two principal forms of anxiety treatment.
Stopping smoking has benefits in anxiety as large as or larger than those of medications.
Cognitive behavioral therapy
The most notable treatment for anxiety is
cognitive behavioral therapy (CBT).
Cognitive behavioral therapy involves the changing of one's thought by
the therapist. Patients are asked to explain their feelings towards
certain things or incidents that cause their anxious behavior.
One study found that
computerized CBT was equally effective as face-to-face CBT in adolescent anxiety.
Herbal treatments
Traditional herbal remedies
have been used for centuries to treat anxiety but many lack strong
evidence of efficacy. There is some limited promising data supporting
the use of
kava and, to some extent,
inositol, but the limited evidence available for
St John's wort,
valerian, and
omega-3 fatty acids demonstrates little efficacy in anxiety and these remedies should not be recommended in place of more effective treatments.
Caffeine elimination
For some people, anxiety may be reduced by eliminating
caffeine consumption.
Anxiety can temporarily increase during caffeine withdrawal.
Other treatments
Other methods used in treating anxiety include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and
psychosurgery. Psychosurgery is used in very extreme cases, when other treatment techniques do not work.
Evidence is insufficient regarding
meditation to make any conclusions.
