Posted on 28 October, 2023 by Mariya Jason

Generalized Anxiety Disorder (GAD) is a common yet debilitating mental health condition that affects a massive portion of the population. In this comprehensive guide, we will delve into the details of GAD, covering its causes, symptoms, diagnosis, and a range of effective treatments available. Our aim is to provide you with in-depth information that surpasses existing sources, enabling you to make informed decisions about managing GAD.

Understanding GAD

What is GAD? Generalized Anxiety Disorder, often abbreviated as GAD, is a chronic condition characterized by excessive, long-term worry and fear that extends beyond a specific event. People with GAD experience anxiety on most days, and it significantly impacts their daily life.

Causes of GAD

While the exact cause of GAD remains partially elusive, research suggests that several factors may contribute to its development, including:

• Brain Activity: Overactivity in areas of the brain related to emotions and behavior.
• Neurochemical Imbalance: An imbalance in brain chemicals like serotonin and noradrenaline, which regulate mood.
• Genetic Predisposition: Individuals with close relatives affected by GAD are more likely to develop the condition.
• Traumatic Experiences: A history of stressful or traumatic events, such as domestic violence, child abuse, or bullying.
• Chronic Health Conditions: Suffering from a painful, long-term health condition, such as arthritis.
• Substance Misuse: A history of drug or alcohol misuse.

It is important to note that GAD can also manifest without a clear identifiable cause.

Who is Affected?

GAD is more common than you might think, estimated to affect about 1 in every 25 individuals in the UK. It slightly affects more women than men, with a higher prevalence in the age group of 35 to 55.

Symptoms of GAD

GAD can affect individuals both mentally and physically, with symptom severity varying from person to person. Here, we explore the psychological and physical symptoms associated with GAD.

Psychological Symptoms

• Restlessness: Individuals may experience a constant sense of unease.
• Dread: A feeling of impending doom or constant worry.
• Edginess: A pervasive sense of being on edge.
• Difficulty Concentrating: Struggles with focus and attention.
• Irritability: Increased sensitivity and irritability in response to various stressors.

These symptoms can lead to social withdrawal, difficulties in the workplace, and a decline in self-esteem.

Physical Symptoms

GAD also presents an array of physical symptoms, including but not limited to:

• Dizziness: Experiencing lightheadedness.
• Tiredness: A constant feeling of fatigue.
• Heart Palpitations: A rapid or irregular heartbeat.
• Muscle Tension: Persistent muscle aches and tension.
• Trembling: Shaking or trembling, often uncontrollable.
• Dry Mouth: A common sensation, often linked to anxiety.
• Excessive Sweating: Profuse sweating, particularly under stress.
• Shortness of Breath: Difficulty in breathing deeply.
• Stomachache: Gastrointestinal discomfort.
• Nausea: Feelings of queasiness.
• Headaches: Frequent or severe headaches.
• Pins and Needles: Tingling sensations.
• Insomnia: Difficulty falling or staying asleep.

Anxiety Triggers

For some anxiety disorders, the triggers are evident, such as specific phobias or panic disorders. However, GAD may not always have clear triggers. This lack of clarity can intensify the anxiety, as individuals worry about not finding a solution.

Diagnosis

Diagnosing GAD can be challenging, and in some cases, it may overlap with other mental health conditions like depression. When seeking diagnosis, individuals are encouraged to openly discuss their worries, fears, emotions, and physical symptoms with a healthcare provider. It is essential to communicate the duration and impact of these symptoms. Diagnosis typically considers the following criteria:

• Significant Daily Impact: Anxiety disrupts daily life, including work and social interactions.
• Stressful Worries: The worries are exceptionally distressing.
• Generalized Worries: A tendency to worry about various aspects of life.
• Uncontrollable Worries: Difficulty in managing or controlling anxiety.
• Chronic Nature: Experiencing worry on most days for at least six months.

Additionally, physical examinations or blood tests may be conducted to rule out other medical conditions contributing to the symptoms.

Treatment Options for GAD

Initial Treatment

Before delving into treatment specifics, a self-help approach is often recommended for individuals with GAD. This self-help course may involve using a book or a computer program designed to aid in anxiety management. Alternatively, group courses facilitated by therapists can provide valuable insights and coping strategies.

Psychological Treatment

For those diagnosed with GAD, psychological treatments are often the first line of intervention. Cognitive Behavioral Therapy (CBT) stands out as one of the most effective treatment methods. CBT helps individuals understand the intricate connections between thoughts, feelings, and behaviors, enabling them to challenge and manage negative thoughts.

Applied Relaxation is an alternative psychological treatment option that focuses on muscle relaxation techniques during anxiety-inducing situations. It involves learning how to relax muscles quickly, especially in response to triggers, and is typically administered in one-hour sessions with a trained therapist.

Medication

If initial treatments do not provide adequate relief or if they are not preferred, medication options are available. Selective Serotonin Reuptake Inhibitors (SSRIs) are frequently prescribed and are known for their effectiveness in GAD treatment. They work by increasing serotonin levels in the brain.

Some common SSRIs used for GAD include sertraline, escitalopram, and paroxetine. These medications may take a few weeks to show results, and side effects may include nausea, low libido, and dizziness.

Another class of medication known as Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs), which include venlafaxine and duloxetine, may be considered if SSRIs are ineffective. SNRIs can also increase blood pressure, requiring regular monitoring during treatment.

Pregabalin, an anticonvulsant medication, may be recommended if SSRIs and SNRIs are not suitable. It is less likely to cause certain side effects, such as nausea and low libido.

Benzodiazepines may be used in the short term for severe anxiety but should be employed cautiously due to the risk of addiction and diminishing effectiveness over time.

Referral to a Specialist

Individuals who do not respond to the treatments and continue to experience significant GAD symptoms may consider a referral to a mental health specialist. This specialist, often part of the community mental health team, can provide a range of services, including therapy and more targeted treatment options.

In conclusion, GAD is a complex condition that can significantly impact daily life. Effective treatment options, including psychological therapies and medication, are available to help individuals manage and overcome this disorder. Understanding the causes, symptoms, and diagnosis of GAD is crucial for making informed decisions about the most suitable treatment approach. If you suspect you may have GAD, seeking professional help is the first step towards a healthier, more anxiety-free life.
