Generalized Anxiety Disorder (Causes)

Extreme, unfounded worry that can interfere with sleep is usually accompanied by body symptoms ranging from tiredness to headaches to nausea. Treatment with antidepressants or other medications and psychotherapy, alone or combined, may alleviate the condition.

Like heart disease and diabetes, anxiety disorders are complex and probably result from a combination of genetic, behavioral, developmental and other factors.

Using brain imaging technologies and neurochemical techniques, scientists are finding that a network of interacting structures is responsible for these emotions. Much research centers on the amygdala, an almond-shaped structure deep within the brain. The amygdala is believed to serve as a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret them. It can signal that a threat is present, thus triggering a fear response (anxiety). It appears that emotional memories stored in the central part of the amygdala may play a role in disorders involving very distinct fears, like phobias, while different parts may be involved in other forms of anxiety.

By learning more about brain circuitry involved in fear and anxiety, scientists may be able to devise more specific treatments for anxiety disorders. It someday may be possible to increase the influence of the thinking parts of the brain on the amygdala, thus placing the fear and anxiety response under conscious control. In addition, with new findings about neurogenesis (birth of new brain cells) throughout life, perhaps a method will be found to stimulate growth of new neurons in the hippocampus in people with severe anxiety.
