Generalised Anxiety Disorder: Causes, Risk Factors, Symptoms, Treatment

Generalised Anxiety Disorder

Generalized Anxiety Disorder (GAD) is a chronic psychological condition characterized by excessive, uncontrollable worry about everyday issues. It is different from normal feelings of anxiety, providing it persists for a longer time (at least six months), causing significant distress and impairment in social, occupational, or other important areas of functioning. The exact causes are unknown but are believed to be a combination of biological factors, family background, and life experiences, particularly stressful ones. Statistics suggest that about 3.1% of the U.S. population is affected by GAD, with a higher prevalence in females. Treatment typically involves psychotherapy, medication, or a combination of both.

Risk Factors of Generalized Anxiety Disorder

If you suspect you or someone else is experiencing Generalized Anxiety Disorder, it is crucial to seek immediate medical attention by calling emergency services or consult with a Psychologist.



While the exact causes of GAD are not fully understood, several factors may contribute to its development: • Genetic Factors: There is evidence to suggest that GAD can run in families, and individuals who have family members with anxiety disorders are at a higher risk of developing GAD themselves. • Brain Chemistry: Neurotransmitters are natural substances that serve as communication agents between nerve cells and are critical for normal brain functions. Imbalances in neurotransmitters like serotonin, dopamine, and norepinephrine are often associated with anxiety disorders. • Personality Factors: Certain personality traits, such as being a perfectionist, having low self-esteem, or the tendency to be easily overwhelmed by stress, can contribute to GAD. • Life Experiences: Prolonged exposure to stressful or traumatic events, such as abuse, the death of a loved one, or significant life changes, can trigger GAD. Chronic medical illnesses or other mental health disorders also increase the risk of developing GAD. • Environmental Stressors: Ongoing stressful situations, like work stress, family or relationship issues, or financial concerns, can contribute to the chronic worry characteristic of GAD.

Risk Factors

• Family History: As with many mental health conditions, having a family member with an anxiety disorder can increase the risk. • Gender: Women are diagnosed with GAD at roughly twice the rate of men. • Age: GAD can develop at any age, but it is most commonly diagnosed in adolescents and adults. • Personality: Individuals with certain personality types, such as those with a tendency toward nervousness or negative affect, are at greater risk. • Traumatic Experiences: People who have experienced trauma, especially in childhood, are at higher risk for developing GAD. • Other Mental Health Disorders: Those with a history of other mental health disorders, such as depression, are at increased risk for GAD. • Substance Abuse: Use of drugs and alcohol can increase anxiety levels and risk of GAD. The risk of complications from GAD can be severe, including impaired social, occupational, or personal functioning. It can lead to or exacerbate other mental health disorders, such as panic disorder or depression. Substance abuse is another significant risk, with individuals sometimes using alcohol or drugs as a form of self-medication.


GAD is characterized by chronic, exaggerated worry and tension that is unfounded or much more severe than the normal anxiety most people experience. The symptoms can be both psychological and physical. Psychological Symptoms: • Persistent worry about various aspects of daily life (work, social interactions, health, minor concerns) • Perceived inability to relax or control the worrying • Overthinking plans and solutions to all possible worst-case scenarios • Indecisiveness and fear of making the wrong decision • Difficulty handling uncertainty or indecisiveness Physical Symptoms: • Restlessness or feeling on edge • Fatigue and general tiredness not related to physical exertion or lack of sleep • Muscle tension • Irritability • Difficulty sleeping (insomnia), unsatisfying sleep, or trouble staying asleep • Sweating, nausea, or diarrhoea These symptoms can be intrusive and significantly affect an individual’s daily life, often interfering with work, school, or relationships. It’s also common for these symptoms to fluctuate, with periods where they are more severe than others.

Diagnosis of Generalized Anxiety Disorder (GAD) involves a comprehensive assessment by a mental health professional. There is no lab test to diagnose GAD, so the process typically includes the following steps: • Clinical Interview: A psychiatrist, psychologist, or other mental health professional will conduct a thorough interview to gather information about symptoms, health history, life events, relationships, and other psychological concerns. • Psychological Questionnaires: Standardized assessment tools or questionnaires may be used to help quantify the anxiety level and compare it to established criteria. One commonly used tool is the Hamilton Anxiety Rating Scale (HAM-A). • Diagnostic Criteria: The professional will refer to criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). For a diagnosis of GAD, anxiety must be present more days than not for at least six months and exhibit specific symptoms. • Ruling Out Other Conditions: It's important to rule out other possible physical or mental health conditions that could be causing the symptoms. Blood tests may be done to check for signs of an underlying medical condition, and a review of any current medications or supplements is conducted to ensure they are not contributing factors. • Assessment of Impact: A key part of diagnosing GAD is determining the impact of symptoms on an individual's ability to function in daily life.


Treatment for GAD is aimed at helping the individual manage symptoms and improve daily functioning. The main treatments are psychotherapy, medication, or a combination of both:   • Psychotherapy: • Cognitive Behavioural Therapy (CBT): CBT is highly effective for GAD. It involves cognitive restructuring to challenge and change unhelpful thoughts and behaviours, anxiety management techniques, and problem-solving skills. • Mindfulness-Based Therapy: This approach incorporates mindfulness meditation to help individuals focus on the present moment and reduce the tendency to worry about the future. • Medications: • Antidepressants: SSRIs (e.g., sertraline, escitalopram) and SNRIs (e.g., venlafaxine, duloxetine) are often first-line medications for GAD. • Buspirone: An anxiolytic that can be particularly helpful for GAD. • Benzodiazepines: These are used cautiously due to potential for dependency, but they can provide short-term relief of acute symptoms. • Lifestyle Changes and Complementary Therapies: • Regular Exercise: Cardiovascular exercise can significantly reduce symptoms of anxiety. • Relaxation Techniques: Activities such as deep breathing, progressive muscle relaxation, and yoga can help alleviate symptoms. • Nutrition: A balanced diet may have a positive impact on overall mood and energy levels.

Preventive Measures

While it may not be possible to prevent GAD, there are steps that can reduce the impact of symptoms and help prevent anxiety from escalating: • Stress Management: Learning and consistently using stress reduction techniques can mitigate the effects of stress. • Build a Strong Support Network: Maintaining close friendships and family ties can provide emotional support and reduce feelings of isolation. • Mindfulness and Relaxation: Regular practice of mindfulness meditation can increase resilience against stress. • Avoid Alcohol and Drug Use: Substances can increase anxiety levels and even trigger or worsen anxiety disorders. • Early Intervention: Addressing symptoms of anxiety early with a professional can prevent them from becoming more severe. • Educate Yourself: Understanding GAD can empower you to take the right steps to manage it effectively. • Healthy Lifestyle Choices: Regular physical activity, sufficient sleep, a balanced diet, and staying hydrated contribute to overall well-being, which can help offset the symptoms of anxiety. It is essential for individuals who suspect they may have GAD or who are experiencing symptoms of anxiety that interfere with their daily life to seek professional help. Early diagnosis and treatment improve the likelihood of successful management of the disorder.
