There are several major types of
anxiety disorders, each with its own characteristics.
•
People
with generalized anxiety disorder have recurring fears
or worries, for example about health or finances, and
they often have a persistent sense that something bad
is just about to happen. The reason for the intense feelings
ofanxiety may
be difficult to identify. But the fears and worries are
very real and often keep individuals from concentrating
on daily tasks.
•
Panic
disorder involves sudden, intense and unprovoked feelings
of terror and dread. People who suffer from this disorder
generally develop strong fears about when and where their
next panic attack will occur, and they often restrict
their activities as a result.
•
Phobic
disorder involves intense fear about certain objects or
situations. Specific phobias may involve things such as
encountering certain animals or flying in airplanes, whereas
social phobias involve fear of social settings or public
places.
•
Obsessive-compulsive
disorder is characterized by persistent, uncontrollable
and unwanted feelings or thoughts (obsessions) and routines
or rituals in which individuals engage to try to prevent
or rid themselves of these thoughts (compulsions). Examples
of common compulsions include washing hands or cleaning
house excessively for fear of germs, or checking over
and over that things are in order and that there are no
errors.
•
Post-traumatic
stress disorder arises from a severe and shocking physical
or emotional trauma, such as a serious accident or violent
crime or a natural disaster. Thoughts, feelings and behavior
patterns become seriously affected by reminders of the
event and whereas most people regain their composure within
a few weeks, some may suffer from these reactions for
months or even years after the traumatic experience.
Symptoms such as shortness of breathe,
racing heartbeat; trembling and dizziness often accompany certain
anxiety disorders such as panic and generalized anxiety disorders.
Although they may begin at any time, anxiety disorders often
surface in adolescence or early adulthood. There is some evidence
of a genetic or family predisposition to certain anxiety disorders.
