Generalized Anxiety Disorder: Causes and Diagnosis


Generalized anxiety disorder (GAD) is characterized by exaggerated and persistent anxiety and worry about a number of different things. People with GAD, worry about common occurrences and situations with no obvious reasons. However, if people with mild to moderate anxiety level receive proper treatment, they can function socially, have full and meaningful lives, and be gainfully employed.

GAD affects 6.8 million adults, or 3.1% of the U.S. population in any given year. Women are twice as likely to be affected than men.


The exact cause of GAD is not fully known, but a few factors appear to contribute to its development.

  • Genetics

Some research suggests that family history and possible child abuse play a part in increasing the likelihood for a person to develop GAD.

  • Environmental factors

Recent or prolonged exposure to stressful situations, such as abuse, the death of a loved one, divorce, changing jobs or schools may be reasons too.

  • Brain chemistry

GAD has been associated with abnormal functioning of certain nerve cell pathways that connect particular brain regions involved in thinking and emotion.

  • Substances

The use of and withdrawal from addictive substances can also worsen anxiety.


People with GAD don’t know how to stop the worry cycle and feel it is beyond their control, even though they usually realize that their anxiety is more intense than the situation warrants.

Psychological and physical symptoms may include:

  • Persistent worrying or anxiety about a number of areas that are out of proportion to the impact of the events
  • Overthinking plans and solutions to all possible worst-case outcomes
  • Perceiving situations and events as threatening
  • Inability to set aside or let go of worry
  • Inability to relax or feeling restless
  • Irritability, fatigue and exhaustion

GAD is diagnosed when a person finds it difficult to control worry on more days than not for at least six months.
