Generalized Anxiety Disorder: Symptoms, Causes & Treatment
Generalized Anxiety Disorder (GAD) is a mental health condition characterized by persistent, excessive worry that can be difficult to control. Unlike occasional anxiety in response to a stressful situation, GAD can cause worry even when there isn't an obvious reason for concern. Over time, it can affect work, school, relationships, sleep, and overall well-being.
Generalized Anxiety Disorder is one of the most common anxiety disorders, affecting millions of adults each year. Understanding the signs and symptoms of GAD can help you determine if what you’re experiencing is more than everyday stress.
In this article, we’ll explore:
What Is Generalized Anxiety Disorder?
Generalized Anxiety Disorder (GAD) is a common anxiety disorder characterized by persistent and excessive worry that lasts for at least six months and is difficult to control. GAD has an annual prevalence of approximately 2.7% to 3% in the United States among adults. GAD is twice as common in women as in men. People with GAD often worry excessively about work, school, finances, health, family, and everyday responsibilities, even when there is no specific reason for concern.
While everyday stress usually comes and goes, symptoms associated with GAD are ongoing and can feel overwhelming. It may interfere with your ability to concentrate, relax, sleep, or enjoy daily activities.
GAD is a treatable mental health condition, and many people experience significant improvement with the right support.

What Causes Generalized Anxiety Disorder?
There is no single cause of Generalized Anxiety Disorder. Research suggests that GAD can develop through a combination of genetic, biological, psychological, and environmental factors. Different factors may contribute to anxiety for different people.
Factors that may increase the likelihood of developing GAD include:
Family history: Having a family history of anxiety or other mental health conditions may increase vulnerability to GAD.
Brain and biological factors: Differences in how the brain responds to stress and perceived threats may contribute to persistent anxiety.
Stressful life experiences: Trauma, major life changes, or periods of significant stress may contribute to the development or worsening of anxiety symptoms.
Ongoing stress: Difficulties involving work, finances, relationships, health, or caregiving can contribute to persistent worry.
Individual differences: Certain patterns of thinking or responding to uncertainty and stress may also play a role.
GAD does not always have an obvious cause, and experiencing one or more of these factors does not necessarily mean someone will develop an anxiety disorder. A mental health professional can help you better understand what may be contributing to your symptoms.
How Is GAD Diagnosed?
There is no single test that can diagnose GAD. Instead, a qualified mental health professional conducts a comprehensive evaluation to better understand your symptoms, history, and how anxiety is affecting your daily life.
During an evaluation, a clinician will ask about your current concerns, how long you have been experiencing your symptoms, and how anxiety is affecting your daily life. They may also ask about your medical and family history, and any important life changes or experiences.
Anxiety symptoms often overlap with other conditions, and a thorough evaluation is important to understand if GAD or a different condition may be contributing to your symptoms. Receiving a diagnosis can provide valuable context for what you’ve been experiencing and help guide an effective treatment plan.
Treatment for Generalized Anxiety Disorder
Generalized Anxiety Disorder is highly treatable, and many people see meaningful improvements with the right support. Treatment is personalized based on your symptoms, goals, and needs.
Therapy is one of the most effective treatments for GAD because it can help you better understand anxious thought patterns, develop healthy coping strategies, and reduce the effect of excessive worry on your daily life. For some, medication may also be an effective part of treatment. A psychiatric provider can help determine if medication is appropriate based on your symptoms and medical history.
Lifestyle habits such as physical activity, sleep, mindfulness practices, and stress management can support overall well-being and complement treatment. At Kendall Psychological Associates, our clinicians use a range of evidence-based approaches tailored to your specific needs, including Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), mindfulness-based approaches, and more.
