For individuals
suffering from a panic attack or anxiety attack, brief episodes of
intense fear are accompanied by multiple physical symptoms (such
as heart palpitations and dizziness) that occur repeatedly and
unexpectedly in the absence of any external threat. These "panic
attacks," which are the hallmark of panic disorder, are believed
to occur when the brain's normal mechanism for reacting to a
threat – the so-called "fight or flight" response – becomes
inappropriately aroused. Most people with panic disorder also
feel anxious about the possibility of having another panic
attack and avoid situations in which they believe these attacks
are likely to occur. Anxiety about another attack, and the
avoidance it causes, can lead to disability. If left untreated,
you may actually begin to have anxiety about having a panic or
anxiety attack in public. This may lead to an even more severe
condition known as
agoraphobia.
One in four
individuals will experience an anxiety attack or panic attack at some
time in their lives. In the United States, 1.6 percent of the
adult population, or more than 3 million people, will go on to
develop a panic disorder. The disorder typically begins in young
adulthood, but older people and children can be affected. Women
are affected with anxiety attacks twice as frequently as men. While people of all
races and social classes can have panic disorder, there appear
to be cultural differences in how individual symptoms are
expressed.
