Anxiety is a common psychological state in modern society, ranging from mild tension to severe health issues. According to data from the World Health Organization, over 260 million people worldwide suffer from anxiety symptoms, indicating that anxiety is not only a personal experience but also a significant public health concern. Anxiety symptoms may be accompanied by physiological reactions such as rapid heartbeat or dizziness and can impact daily life and interpersonal interactions. Therefore, understanding its causes, symptoms, and coping strategies is crucial.
There are various manifestations of anxiety, which may originate from environmental stressors, genetic predisposition, or physiological changes. The accelerated pace of modern life, information overload, and other social factors make anxiety a common challenge across all age groups. However, with proper understanding and professional assistance, the vast majority of patients can effectively alleviate symptoms and restore normal functioning. This article will explore the causes, diagnostic criteria, treatment options, and prevention strategies of anxiety to help readers grasp the key concepts of "Overview of Anxiety."
Neuroscientific research indicates that anxiety is closely related to imbalances in neurotransmitters within the brain. Changes in chemicals such as serotonin and dopamine can affect emotional regulation mechanisms, such as abnormal interactions between the prefrontal cortex and amygdala, potentially leading to hypervigilance responses. Genetic studies also show that certain familial tendencies for anxiety are 30% to 50% more prevalent than in the general population.
Hormonal system abnormalities also play a critical role. Prolonged stress can lead to excessive secretion of adrenaline and cortisol, resulting in a chronic "fight or flight" response. This physiological maladaptation may cause individuals to become overly sensitive to everyday stressors, creating a vicious cycle.
Psychological theories, such as Beck's cognitive theory, suggest that negative thought patterns act as catalysts for anxiety. Individuals who habitually hold beliefs like "must be perfect in everything" or "catastrophize" tend to perpetually stimulate anxiety responses. Social environment factors, such as tense family relationships, excessive workplace pressure, or major life changes (e.g., unemployment, relocation), are identified as high-risk triggers.
Anxiety symptoms often manifest initially through physiological signs. Common symptoms include sweating palms, muscle tension, frequent belching, or gastrointestinal discomfort. Some patients may experience symptoms similar to cardiac issues, such as chest tightness and palpitations, which are often misdiagnosed. Detailed clinical assessment is necessary to differentiate these.
Overactivity of the autonomic nervous system can lead to various physiological changes, including:
Psychologically, individuals with anxiety often fall into a cycle of "rumination," engaging in catastrophic predictions about events that have not yet occurred. This "anticipatory anxiety" can lead to insomnia, difficulty concentrating, and other issues. Behaviorally, patients may exhibit avoidance behaviors, such as avoiding social situations or specific locations, which can develop into agoraphobia and other related problems.
In clinical diagnosis, if symptoms persist for more than six months and significantly impair daily functioning, they are classified as Generalized Anxiety Disorder (GAD). Such patients often complain of "cannot stop worrying" and exhibit at least three symptoms, including anxiety, restlessness, fatigue, concentration difficulties, irritability, muscle tension, or sleep disturbances.
Diagnosing anxiety requires a comprehensive assessment process. The first step is to rule out physiological illnesses, such as thyroid dysfunction or metabolic disorders, which may cause similar symptoms. Physicians will conduct detailed medical history inquiries, including the onset time of anxiety, triggers, and exacerbating factors.
Psychological assessment tools include the Hamilton Anxiety Rating Scale (HAMA) and the Generalized Anxiety Disorder 7-item scale (GAD-7). These standardized questionnaires quantify symptom severity and assist clinicians in distinguishing normal anxiety responses from pathological conditions. Additionally, DSM-5 criteria require symptoms to persist for at least six months and exclude effects of medications or substance use.
Cognitive Behavioral Therapy (CBT) is considered a first-line treatment, focusing on helping patients identify and correct distorted thinking patterns. Therapists guide individuals in developing skills to challenge negative thoughts, such as through behavioral experiments testing catastrophic predictions. Exposure therapy is used for specific anxiety disorders, such as phobias, involving systematic exposure training.
Medication is typically used for moderate to severe symptoms. Selective Serotonin Reuptake Inhibitors (SSRIs), such as sertraline, are often first-line drugs, with an onset period of approximately 4-6 weeks. In acute episodes, benzodiazepines (e.g., alprazolam) may be used to alleviate immediate anxiety, but caution is needed due to addiction risks.
Stress management techniques such as mindfulness meditation have been shown to reduce amygdala activity. Regular aerobic exercise can promote brain-derived neurotrophic factor (BDNF) secretion, aiding neural plasticity repair. Nutritional factors, such as magnesium and B vitamins, may also influence symptoms; a balanced diet is an important adjunct to treatment.
Preventing anxiety escalation into clinical symptoms involves adopting healthy daily habits. Establishing a regular sleep cycle can stabilize prefrontal cortex function, with recommended 7-9 hours of deep sleep each night. Time management training can reduce stress from multitasking, such as using Eisenhower's matrix to prioritize urgent and important tasks.
Strengthening social support systems is a key preventive measure. Regular deep communication with family and friends or participation in support groups can reduce feelings of isolation. In workplaces, providing mental health education and stress management courses can effectively lower workplace anxiety risks.
If anxiety symptoms persist for more than two weeks and worsen gradually, interfere with daily work or social functions, or if there are tendencies toward self-harm or suicidal thoughts, professional help should be sought. For example, a sharp decline in work performance due to persistent worry or frequent sick leave caused by anxiety warrants assessment.
Emergency signs include difficulty breathing with chest pain, dissociation during panic attacks, or suicidal plans triggered by anxiety. Immediate hospital visits or contact with crisis hotlines are advised. Non-urgent cases can initially be referred by a family doctor for preliminary assessment before specialist treatment.
Regular exercise promotes the release of endorphins in the brain, helping to relieve stress and improve mood stability. Aerobic activities such as jogging and swimming can lower cortisol levels, while gentle stretching combined with deep breathing techniques can reduce palpitations and muscle tension, thereby decreasing physiological symptoms of anxiety.
How can one differentiate between normal stress responses and pathological anxiety in daily life?Normal stress responses are usually related to specific events and last for a short duration, whereas pathological anxiety may lack clear triggers, and symptoms like palpitations, cold sweats, or panic attacks persist for over six months. If these symptoms interfere with social or work functions, professional psychological evaluation is recommended.
What role does medication play in the treatment of anxiety disorders?Anti-anxiety or antidepressant medications help regulate neurotransmitters and are used for acute symptom control. However, they should be combined with psychological interventions like CBT for long-term improvement. Medications are generally short-term adjuncts, and long-term use should be carefully evaluated for side effects and dependency risks under medical supervision.
What is the scientific basis for dietary adjustments in alleviating anxiety symptoms?Foods high in magnesium and omega-3 fatty acids (such as oily fish and nuts) can help relax the nervous system, while excessive caffeine or refined sugar may trigger increased heart rate and anxiety responses. Studies indicate that B vitamin supplementation can improve the brain's stress regulation, but should be done under the guidance of a nutritionist.
How can family and friends effectively support individuals with anxiety without exacerbating their distress?Support should focus on listening rather than offering advice, avoiding dismissive phrases like "don't worry so much." Assisting in establishing regular routines and positive behaviors, such as outdoor activities, can be beneficial. During crises, maintaining a calm tone and encouraging professional treatment rather than solely offering spontaneous comfort are recommended.
