Understanding Anxiety

Learn about anxiety

Anxiety is a normal part of the adolescent and teen years as these are some of the most stressful times in a person’s life. Some anxiety is a normal reaction to stressful situations. It can help teens deal with a tricky situation, study harder for an exam, and maintain focus on an important task. For most individuals, anxiety is often a harmless phase that lasts for a while and dissipates on its own. However, there are a variety of anxiety disorders that can impact the lives of children, leading them to experience fear, shyness, and nervousness, and can cause them to avoid certain activities and places.

Anxiety disorders, one of the most common types of mental health concerns experienced by all ages, are mental health disorders that include extreme amounts of unremitting fear, nervousness, dread, or worry. When anxiety becomes an excessive, irrational dread, it has become a disabling yet treatable mental health condition. The most common forms of adolescent anxiety disorders include:

Generalized anxiety disorder (GAD) is characterized by extreme worry about a variety of events – including past, present, and future events. Children and teens with GAD worry about a lot of issues, including past conversations or behaviors, upcoming events, school, family problems, their health, competences in academics or sports, and world events. Many teens with GAD find that they have difficulty controlling their extreme amounts of worry and that the anxiety interferes with their daily life. GAD occurs more days than not for periods of six months or longer.

Panic disorder leads to recurrent panic attacks and a persistent anxiety that an attack may lead to more panic attacks or physical or psychological harm. Teens who have panic disorder may avoid going out and engaging in activities out of fear an attack may occur. Panic attacks include feelings of intense fear and unease composed of physical symptoms and fearful thoughts. Untreated, this can lead to agoraphobia.

Separation anxiety can be caused by unwillingness to separate from major attachment figures or from home. Threat of having to separate from caregivers leads to anxiety. While separation anxiety can be seen mostly in children, it can also be experienced by teens as well.

Social phobia is the intense fear of embarrassment or humiliation in social situations, which may lead to shyness and a fear of doing or saying something in front of others that may promote embarrassment. This may include attending parties, speaking with figures in authority, or fears of speaking in public.

Specific phobias: Teens may experience specific phobias— intense, irrational fears of specific things and situations. Teens may not realize that their fears of such objects are unreasonable. Exposure to the feared object or situation leads to extreme distress.

With treatment of high-quality cognitive-behavioral therapy and medication management, many adolescents who have anxiety disorders can be effectively treated for anxiety disorders.


Anxiety statistics

A national survey discovered that approximately 8% of adolescents (or one in eight children) between the ages of 13 and 18 have an anxiety disorder; typical symptoms appear around age 6. Of these teens with anxiety disorders, only about 18% received the mental health care needed to make a recovery.

Causes and Risk Factors

Causes and risk factors for anxiety

Anxiety disorders in the teen years are thought to be the result of a number of factors working together. Some of the most common causes and risk factors for adolescent anxiety disorders may include:

Genetic: Adolescents who have a first-degree relative who has an anxiety disorder are at greater risk for developing anxiety disorders than those who do not have a similar history.

Physical: Neuroimaging studies showed that teens with anxiety disorders have atypical activity in certain areas of the brain when compared with their peers.

Environmental: Extremely stressful events, such as the death of a loved one, sudden move to a new area, or the divorce of parents, can bring about anxiety disorders. Additionally, when children grow up in a home where others are fearful, it can lead them to believe the world is a dangerous place. Other children who grow up in a dangerous home may also become fearful.

Risk Factors:

  • Being female
  • Traumatic events during childhood years
  • Stress due to chronic illness of a teen or his or her parent
  • Personalities that are prone to worrying
  • Usage of drugs or alcohol
