Anxiety Signs, Symptoms & Effects

Generalized anxiety disorder (also referred to as GAD) is a mental disorder that is characterized by extreme, pervasive, and unrealistic worries about everyday life.

Understanding Anxiety

Learn about anxiety

A small amount of anxiety or stress can be helpful because it may allow an individual to perform better on an important exam or get more tasks done during the day. However, individuals with GAD or another type of anxiety disorder have feelings of worry more often than not, which can cause them to have difficulty with daily life.

Typically, the presence of an individual’s extreme worry cannot be pinpointed; yet, they have persistent feelings of dread and fear. Anxiety disorders can affect thinking and productivity at work, as well as sleep patterns, causing one to sleep too much or not at all. Often, one cannot stop this endless cycle of worry.

The severity of anxiety symptoms will vary, and some people who have generalized anxiety disorder can function socially and remain employed or in school. Others may avoid certain situations that trigger anxiety or face challenges performing the most ordinary daily activities when anxiety levels are high. Generalized anxiety disorder and other types of anxiety disorders can be chronic illnesses that require long-term treatment, which typically includes therapy and medication.


Anxiety statistics

Generalized anxiety disorder is a very common issue for many people and is the most common anxiety disorder diagnosed by clinicians. GAD affects about 3.1% of the U.S. population (or 6.8 million adults) each year, with women being twice as likely to be affected as men. While it most often develops in the early 20s, generalized anxiety disorder can impact children as well – over the span of childhood, about 20% of children will be impacted by GAD or panic disorder.
