Generalised Anxiety Disorder
What is Generalised Anxiety Disorder?
Generalized Anxiety Disorder (GAD) is one of the more common anxiety disorders. Women are more than twice as likely to be affected as men. GAD typically begins between the ages of 20 and 40. Patients often experience uncontrollable worry about various aspects of life for most of the time, with the following specific symptoms:
1. Excessive worry or distress about daily matters or future events, leading to constant agitation
Patients often have a sense of impending panic, feeling restless and anxious throughout the day, as if something bad is about to happen. Some patients have clearer worries, while others cannot specify what exactly they are concerned about.Physical Symptoms
2. Physical Symptoms
Persistent anxiety can affect the autonomic nervous system, leading to various physical symptoms, including restlessness, rapid heartbeat, chest discomfort, difficulty breathing, trembling hands, excessive sweating, dizziness, abdominal cramps and diarrhea, frequent urination, neck and shoulder pain, and limb numbness. Symptoms can vary among patients with generalized anxiety disorder.
3. Heightened State of Alertness
Patients may be overly sensitive to external stimuli and more easily agitated by minor issues. They often find it difficult to concentrate at work, as worrying thoughts can be distracting, and their memory may be weaker. Sleep is also often affected, making it harder to fall asleep or causing frequent awakenings during the night.
What is Anxiety?
Anxiety is a basic human emotion that has developed in response to the struggle and adaptation to the environment. When people face potential or real dangers or threats, they experience emotional responses of anxiety. This is an innate defense mechanism that prompts individuals to respond promptly to avoid danger. However, suppose anxiety becomes excessive relative to the stressor or persists even after the stressor has disappeared, leading to impacts on daily life, social interactions, work, or relationships. In that case, it may indicate an anxiety disorder.
How is Anxiety Disorder Different from Depression?
Both are common emotional disorders. Patients with depression often experience prolonged periods of low mood, accompanied by a loss of interest in things or activities, and may have various negative thoughts, such as feeling worthless, believing that life has no future, or frequently regretting past actions. In contrast, patients with anxiety disorder often worry excessively about events that have not yet occurred and find themselves in a state of constant agitation.
A common saying summarizes the difference: patients with depression live in the past, while those with anxiety live in the future. However, the symptoms of anxiety and depression often occur together in clinical settings, and the diagnosis usually depends on which condition is more severe.
What Causes Anxiety Disorders?
The causes of anxiety disorders are multifaceted. In addition to psychological stress, significant life events, excessive self-demanding personality traits, and a tendency to doubt oneself can increase the likelihood of developing generalized anxiety disorder. On a physiological level, factors primarily related to genetics and imbalances in neurotransmitters in the brain also play a significant role.
Treatment Options
Currently, the treatment methods for generalized anxiety disorder primarily include medication and psychotherapy. Depending on the severity of the condition, both approaches can be used simultaneously or just one may be employed.
In terms of medication, sedatives and anti-anxiety medications are commonly prescribed. The benefit of sedatives is that they can quickly alleviate symptoms in a short period, but patients may develop a dependence on them, so long-term use is not recommended. Anti-anxiety medications, on the other hand, work by adjusting the levels of neurotransmitters in the brain (such as serotonin and norepinephrine) to address the underlying causes of anxiety. However, these medications may take longer to show effects, and patients may not notice significant improvement in the early stages of treatment. Some patients may experience increased tension and loss of appetite when starting medication, but these side effects typically diminish over time. Therefore, it is common to use a combination of sedatives and anti-anxiety medications during the initial treatment phase.
Clinical studies have shown that Cognitive Behavioral Therapy (CBT) can effectively improve the condition of patients with anxiety disorders. This treatment method helps patients gain a better understanding of the interplay between their emotions, physical reactions, thoughts, and behaviors, assisting them in facing and addressing troubling issues while alleviating feelings of anxiety.
When managed properly, most patients can begin to see improvements within a few weeks. Generally, patients with a shorter duration of illness and milder symptoms tend to recover more quickly.
