Anxiety disorders are the most common mental health problem worldwide, affecting approximately 301 million people in 2019, according to the Global Burden of Disease Study (2021 update). These disorders are characterized by excessive fear, anxiety, and a variety of physical and behavioral reactions. They can make it difficult to go about daily life, relate to people, be productive at work, and generally enjoy life. Anxiety disorders are conditions in which people experience persistent, intense and often irrational fears that disrupt their daily lives. It is normal to feel anxiety from time to time.
Description and Basic Features
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR, 2022) and the International Classification of Diseases (ICD-11) define anxiety disorders as conditions characterized by excessive fear, anxiety and accompanying behavioral disturbances.
Fearis the emotional response to a real or imagined threat that is about to occur.
Anxiety (anxiety)It is the concern about a threat that may occur in the future.
Common physical symptoms include: heart palpitations, sweating, tremors, difficulty breathing, muscle tension, gastrointestinal issues, and sleep problems. Catastrophizing thoughts, hypervigilance, and difficulty concentrating are common cognitive impairments.
Most Common Types of Anxiety Disorders
Generalized Anxiety Disorder (GAD/GAD)
Approximately 6.8 million adults in the United States have GAD; This corresponds to approximately 3.1% of the population. About many areas of life such as work, health, finances and relationshipsfor at least six months, lasting most daysexcessive and uncontrollableIt is characterized by anxiety. Anxiety is accompanied by at least three of the following symptoms: restlessness, easy fatigue, difficulty focusing, irritability, muscle tension, and sleep disturbance. GAD usually begins in childhood or adolescence; but it can occur at any age. It is twice as common in women than in men.
Panic Disorder
In panic disorder, the person experiences unexpected and recurring panic attacks. Panic attacks are sudden and intense bouts of fear or discomfort that last several minutes. At least four symptoms occur during an attack: palpitations, sweating, tremors, feeling of shortness of breath, chest pain, nausea, dizziness, chills or hot flushes, numbness-tingling, feeling of unreality (derealization), fear of losing control or fear of dying. One of the most prominent features is the fear of having a new attack or making drastic changes in behavior to prevent it (e.g. avoiding exercise or new environments). The lifetime incidence rate is approximately 4.7%.
Social Anxiety Disorder (Social Phobia)
It is characterized by intense fear and anxiety about social environments where the person may be evaluated by others. It is evident in situations such as talking to people, meeting new people, speaking in public, eating and drinking in front of others, or performing. The person is afraid of humiliation, embarrassment or rejection. When exposed, intense anxiety almost always occurs, and the person either avoids these situations or endures them with great distress. The lifetime incidence is between 7% and 13% and it usually begins in late childhood or early adolescence.
Specific Phobias
It is intense fear or anxiety towards a specific object or situation (airplane, height, animals, blood-needle-injury, closed spaces, etc.). The phobic stimulus almost always produces immediate fear, the person actively avoids it, and the fear is disproportionate to the actual danger. The duration is at least six months. Specific phobias are the most common type of anxiety disorder, with a lifetime rate of 7–9%.
Agoraphobia (Fear of Open Spaces)
It is the fear and anxiety about environments where escape may be difficult or help cannot be received when panic-like symptoms occur. Situations such as using public transportation, being in open or closed spaces, waiting in a crowd or in a queue, and being outside alone are typical. The person avoids these situations, cannot enter them without someone, or endures them with intense fear. Since DSM-5, it has been considered a separate diagnosis from panic disorder. The incidence is approximately 1.4%.
Separation Anxiety Disorder
This disorder, which was once considered specific only to childhood, can now be seen at all ages. It is characterized by extreme fear and anxiety about separation from attached people. During or thinking about the separation, intense distress, concerns that something will happen to loved ones, refusal to leave home or sleep elsewhere, and separation-related nightmares may occur. The incidence rate in adults is thought to be between 0.9-1.9%.
Selective Mutism
It is a rare but serious disorder that usually begins in early childhood. While the person cannot speak continuously in some social environments (for example, at school), he or she speaks normally in other environments. Today, it is included in the class of anxiety disorders because the main problem is anxiety about speech, not oppositional behavior.
Etiology: A Biopsychosocial Framework
Anxiety disorders; It occurs through the complex interaction of biological, psychological and environmental factors:
-
Genetic:Twin and family studies show that hereditary transmission is between 0 and 50. Genome-wide studies have identified many risk regions, especially those related to neurotransmitter systems such as serotonin, GABA and noradrenaline, and stress response pathways (HPA axis, CRH).
-
Neurobiology:The amygdala (fear perception), prefrontal cortex (fear regulation), hippocampus (contextual memory), and stria terminalis nucleus bed (chronic anxiety) are basic brain circuits. fMRI studies generally show overactivity of the amygdala and underactivity of prefrontal regulatory regions.
-
Temperament:Behavioral inhibition (shyness and timidity) seen in early childhood is an important predictor.
-
Environmental factors:Childhood trauma, abuse, excessive parental control, modeling of anxious behavior, chronic stress, and major life events significantly increase risk.
-
Cognitive factors:Selective attention to threats, negative interpretation of ambiguous situations, and the tendency to exaggerate danger contribute to the perpetuation of disorders.
Comorbidities and the Course of the Disease
Anxiety disorders rarely occur alone. More than half of patients have at least one additional mood or anxiety disorder. Major depression (lifetime risk), substance use disorders, post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (a separate class in DSM-5), and somatic symptom disorders are the most common comorbidities. Ongoing sympathetic nervous system activation; It may increase the risk of heart disease, diabetes and digestive diseases.
If left untreated, most anxiety disorders are chronic and symptoms may come and go. Early onset (childhood/adolescence) is associated with worse prognosis and more comorbidities.
Treatment Methods
Psychotherapy
Cognitive Behavioral Therapy (CBT) is the psychological treatment with the strongest evidence (effect size 0.8–1.2). Psychoeducation, cognitive restructuring, exposure (gradual or internal), and relapse prevention are essential components.
Exposure and Response Prevention (ERP) is particularly effective for specific phobias and agoraphobia.
Acceptance and Commitment Therapy (ACT) and Mindfulness-Based approaches offer promising results, especially for Generalized Anxiety Disorder.
Pharmacotherapy
First-line drugs:
-
SSRIs: escitalopram, sertraline, paroxetine
-
SNRIs: venlafaxine, duloxetine
Second digit:
Benzodiazepines (short-term only, due to risk of addiction), buspirone, pregabalin, hydroxyzine or beta-blockers (for performance anxiety).
Once symptoms have resolved, treatment is usually administered to prevent recurrence.at least 12 monthsis continued.
Co-treatment
Meta-analyses have shown that the combination of CBT and medication provides slightly superior results in the short term compared to either method alone; However, it shows that psychotherapy alone is more powerful in terms of long-term protection.
New and Supportive Treatments
-
Transcranial Magnetic Stimulation (TMS) and Deep Brain Stimulation in treatment-resistant cases
-
Clinical studies conducted with psychedelic-assisted therapies (MDMA, psilocybin)
-
Digital CBT programs found to be as effective as face-to-face therapy
-
Exercise as an evidence-based improvement strategy
Impact on Public Health and Stigma
According to Global Burden of Disease data (GBD 2019), anxiety disorders are the sixth most common cause of disability in the world. Its economic burden is extremely high; In the USA alone, the annual cost is over $40 billion. Although effective treatments are available, only 5–40 of the individuals who need help can access treatment; The proportion receiving evidence-based care is even lower. Stigma, low mental health literacy, and barriers to accessing services remain major problems.
Conclusion
Anxiety disorders are very common, serious, but alsohighly treatableare mental illnesses. Advances in neuroscience, genetics, and psychotherapy allow us to better understand and effectively treat these disorders. Early diagnosis, reducing stigma and increasing access to evidence-based treatments are of great importance for public health. With the right treatment, most people can regain their life and health; Significant reduction in symptoms and even complete recovery can be achieved.
