Understanding Anxiety

Learn about anxiety

Generalized anxiety disorder (GAD) is a type of anxiety disorder characterized by excessive anxiety and fear over everyday events and activities. While some amount of anxiety can be helpful, allowing a person to meet deadlines or cram for an exam, a person who has an anxiety disorder experiences anxiety that is much more excessive and far less helpful. Symptoms of anxiety disorders are pronounced, distressing, and pervasive; people with GAD worry even when there is little to no reason to worry. Also referred to as “free-floating anxiety,” people with GAD report that anxiety often comes out of nowhere without any precipitating event. They have a difficult time controlling their anxiety and worry; attempts to do so often make the problem worse. They often develop a sense of helplessness since it seems like nothing they do can decrease their worries, leading to the development of other psychosocial problems. Fortunately, with the help of certain types of medication and ongoing therapies, people who have anxiety disorders are able to reclaim their lives.

Statistics

Anxiety statistics

In the United States, it is estimated that 0.9% of adolescents and 2.9% of adults suffer from GAD in a given year. The lifetime risk for developing anxiety disorders is 9% with the average age of onset at age 30. Females are twice as likely to experience this disorder, however this may be the result of women being more apt to report their symptoms than men. The younger the person is when the disorder develops, the more likely there will be co-occurring disorders and the greater the impairment.

Causes and Risk Factors

Causes and risk factors for anxiety

It’s unlikely that a person will develop an anxiety disorder for a single reason. It’s widely accepted that most people develop anxiety disorders as a result of the complex interplay of a variety of causes and risks factors. Some of the causes for anxiety disorders include:

GeneticPeople who have first-degree relatives, such as a parent or sibling, with anxiety disorders are at higher risk for developing these disorders themselves. It’s worth noting that while many people have a genetic predisposition to the disorder, a number of people who develop anxiety disorders do not have a family history.

Brain ChemistryAbnormal levels of certain neurotransmitters, the chemical messengers of the brain, are thought to play a role in the developmental of anxiety disorders. Neurotransmitters such as serotonin, dopamine, and norepinephrine play a role in anxiety control and low levels of these neurotransmitters may incorrectly signal that danger is near. Additionally, parts of the brain that regulate fear, memory and emotion are highly sensitive to unfamiliar or unpredictable situation, which can lead to the development of an anxiety disorder.

Environmental: Individuals who have experienced numerous and severe stressors including traumatic events, multiple deaths of loved ones, being placed in dangerous situations, divorce, sudden illness, moves, job loss etc., are more likely to develop generalized anxiety.
