What Causes Anxiety Disorders
to Develop?
New technologies are enabling researchers and scientists to learn more
about the biological, psychological, and social factors that influence the
development of an anxiety disorder. With a better understanding of underlying
causes, better treatment and even prevention measures will be possible.
The following are all believed to play a role in the occurrence of anxiety
disorders:
- heredity
- brain chemistry
- personality
- life experiences
Heredity and anxiety disorders:
There is clear evidence that anxiety disorders run in families. Studies show
that if one identical twin has an anxiety disorder, the second twin is more
likely to have an anxiety disorder than non-identical (fraternal) twins. These
findings suggest that a genetic factor, possibly activated in combination with
life experiences, predisposes some people to these disorders.
Brain chemistry and anxiety
disorders:
Because symptoms of anxiety disorders are often relieved by medications that
alter levels of chemicals in the brain, scientists believe that brain chemistry
appears to play a role in the onset of anxiety disorders.
Personality and anxiety disorders:
Researchers believe that personality may play a role in the development of an
anxiety disorder, noting that people who have low self-esteem and poor coping
skills may be more prone. Conversely, an anxiety disorder that begins in
childhood may itself contribute to the development of low self-esteem.
Life experiences and anxiety disorders:
Researchers believe that the relationship between anxiety disorders and
long-term exposure to abuse, violence, or poverty is an important area for
further study, as life experiences may affect an individual's susceptibility to
these disorders.
Sometimes anxiety may be caused by using street drugs like amphetamines, LSD
or Ecstasy. Even the caffeine in coffee can be enough to make some of us feel
uncomfortably anxious!
