Introduction

Fear is an alarm response to current or impending danger (actual or perceived), while anxiety is a future-focused mood state linked to preparing for potential, upcoming bad occurrences. This perspective compares the animal predatory imminence continuum to human fear and anxiety. In other words, fear relates to an animal’s state during predator contact or impending contact, while anxiety relates to an animal’s state during a possible predatory attack.

According to the definitions of anxiety and fear, Lang categorized the symptoms of fear and anxiety into three responses: verbal-subjective, overt motor acts, and somato-visceral activity. Within this system, the symptoms of anxiety include worry (verbal-subjective), avoidance (overt motor acts), and muscle tension (somato-visceral activity), while the symptoms of fear include thoughts of impending danger (verbal-subjective), escape (overt motor), and a strong autonomic surge that causes physical symptoms like sweating, shaking, palpitations, and nausea (somato-visceral).

Anxiety disorder prevalence was gathered from 87 studies conducted in 44 different countries. Prevalence estimates for the previous year ranged from 2.4% to 29.8%, while current prevalence estimates ranged from 0.9% to 28.3%. The largest percentage of variability was explained by substantive characteristics, such as gender, age, culture, conflict and economic status, and urbanicity. An extra 13% of the variation between studies was explained by methodological factors (prevalence period, number of illnesses, and diagnostic tool) in the final multivariate model. After accounting for methodological variations, the current prevalence of anxiety disorders worldwide was 7.3% (4.8–10.9%), with the range being 5.3% (3.5–8.1%) in African cultures and 10.4% (7.0–15.5%) in Euro/Anglo cultures.

Global Prevalence of Anxiety Disorders and Regional variation

Geographical differences in the point prevalence of anxiety disorders ranged from 2.1% (1.8–2.5%) in East Asia to 6.1% (5.1–7.4%) in North Africa/Middle East, a threefold difference. Latin America, high-income areas, and areas with a recent history of conflict have higher rates of anxiety. Estimates were highly questionable, especially for regions for which no data were available. To determine if geographical disparities in the prevalence of anxiety disorders are significant or the result of methodological or cultural differences, more study is needed.

Although there was a 36% increase in the crude number of cases, this was explained by shifting age patterns and population growth. In 1990, the estimated point prevalence of anxiety disorders was 3.8% (3.6–4.1%), and in 2010, it was 4.0% (3.7–4.2%). In 1990 (4.2–4.7%) and 2010, the prevalence of MDD remained constant at 4.4% (4.1–4.7%). But according to eight out of the eleven GHQ trials, psychological discomfort significantly increased over time.

Influence of culture on anxiety

The experience and expression of emotions are influenced by a person’s cultural background. After reviewing the recent literature on cross-cultural aspects of anxiety disorders, we identified some culturally related ethnopsychology/ethnophysiology factors (the culture’s conceptualizations of how the mind and body function) and contextual factors that influence anxiety disorders. While contextual factors are linked to the social norms and rules that may contribute to anxiety, such as self-construals and individualism vs. collectivism, we will discuss “khyâl cap” (“wind attacks”), taijin kyofusho, and ataques de nervios, three well-known examples of culturally specific expressions of anxiety disorders that have all been included in the DSM-5 list of cultural concepts of distress.

Due to linguistic, evaluation, political, geographic, and sociodemographic variations, it is challenging to directly compare prevalence rates between cultures. Comparing several cultural groups within the same multicultural nation may yield a more accurate estimate of the differences in prevalence rates between them. one such study evaluated the prevalence rates of anxiety disorders within a large representative sample of the US population, oversampling Hispanic Americans (N = 3,615), Asian Americans (N = 1,628), and African Americans (N = 4,598) [4]. The findings demonstrated that compared to all other racial groups, Asian Americans consistently endorsed symptoms of all four main anxiety disorders—social anxiety disorder, panic disorder, generalized anxiety disorder, and post-traumatic stress disorder—less frequently. Compared to African Americans (8.6%, 4.9%, 3.8%, respectively), Hispanic Americans (8.2%, 5.8%, 4.1%, respectively), and Asian Americans (5.3%, 2.4%, 2.1%, respectively), White Americans (N = 6,870) consistently supported symptoms of social anxiety disorder (12.6%), generalized anxiety disorder (8.6%), and panic disorder (5.1%). Compared to the White American subgroup (6.5%), Hispanic Americans (5.6%), and Asian Americans (1.6%), African Americans were more likely to meet the criteria for post-traumatic stress disorder (PTSD) (8.6%).

Cultural Perceptions of anxiety and Stigma with it

A meaningful and statistical relationship between these variables was hypothesized, and Asians and Westerners would differ in this relationship. The study included 287 British Asian, western European, and Pakistani individuals. Method: Participants completed the Orientations to Seeking Professional Help (Fischer and Turner 1970), Mental Distress Explanatory Model Questionnaire (Eisenbruch 1990), and demographic data sheet. Results: Similar positive opinions toward obtaining professional treatment for psychological distress were found in British Asians, Westerners, and Pakistanis. The three groups’ mental anguish causation attributions differed significantly. Culture did not predict a positive attitude to seeking professional help, but causal views of mental suffering did for British Asian and Pakistani populations. Western attitudes to requesting aid were not predicted by beliefs. Conclusion: Culturally influenced mental distress causation beliefs influence Asians’ attitudes toward obtaining professional care for psychological issues. The implications for research and better health services for the British Asian minority community are highlighted.

There is a huge difference between the help seeking behaviors of the different communities. The decision of whether or not an individual will seek professional assistance or rely on traditional healing practices is influenced by cultural norms. For instance, due to cultural beliefs and a lack of trust in established healthcare institutions, some Latino populations may seek the advice of folk healers rather than professional medical professionals.

Impact of Acculturation

Acculturation is defined as the process by which a person accepts, learns, and adapts to a new cultural setting as a result of being immersed in a different culture or when someone is introduced to another culture. The phrase “culture change” is used in workplaces and public policymaking to highlight how cultural capital affects both individual and collective behavior. The reconstruction of a society’s cultural concept has been referred to as “repositioning of culture”. It emphasizes how social and cultural capital influence decision-making and how they combine with other elements, such as information accessibility or the financial incentives people face to influence their behavior.

The first psychological theory of acculturation was proposed in W.I. Thomas and Florian Znaniecki‘s 1918 study, The Polish Peasant in Europe and America found that Polish immigrants in Chicago showed three types of acculturation that match three personality types: the Bohemian type adopted the host culture and gave up their own culture, the Philistine type failed to adopt the host culture but kept their own culture, and the creative type was able to adapt to the host culture while keeping their own culture.

Getting used to a new society can be stressful for immigrants and refugees, which can make their anxiety symptoms worse. Language barriers, discrimination, and losing social support are some of the things that make this worry worse. It can vary with different generations depending on how much they adopt new culture and how much they hold on to traditional values, first-generation immigrants may feel different amounts of anxiety than later generations. This can also apply to the new workplace when they change their working environment, they experience different symptoms of anxiety or stress that is associated with the unable to adapt with the new culture a process explained as marginalization (sidelined in new culture) in the literature.

Contributing Factors to Anxiety

There are a lot of biological, psychological, environmental, and lifestyle factors that can lead to anxiety conditions. To manage and avoid problems well, you need to know about these factors that affect them. Here’s a thorough look at the things that can cause anxiety.

1.Biofactors

Genetic: A genetic susceptibility to anxiety is often found in families.
Research Source: According to Smoller et al. (2009) in Nature Reviews

Neurotransmitter Imbalances: Neuroscience, genetic differences in neurotransmitter pathways are associated to anxiety disorders. Increased anxiety can result from dysregulation of neurotransmitters such as serotonin, dopamine, and GABA.
Example: Low GABA levels enhance brain excitability, a hallmark of anxiety.

2.Psychological Factors

Negative Thought Patterns: People who have low self-esteem, perfectionism, and persistently negative thoughts are more likely to experience anxiety.
Catastrophizing is one cognitive distortion that makes anxiety symptoms worse.

Trauma and Adverse Experiences: Anxiety is more likely to develop in those who have experienced trauma, particularly as children.
Citation for Research: The effect of Adverse Childhood Experiences (ACEs) on mental health outcomes was covered by Felitti et al. (1998).

3.Environmental Factors

Stressful Life Events: Anxiety can be triggered by situations like losing one’s job, being divorced, or losing a loved one.

Social and Economic Stressors: Unemployment, social inequality, and financial instability all play a big role. (The Lancet Psychiatry)

4.Lifestyle Factors

Absence of Physical Activity: Since exercise is known to lower stress and elevate mood, sedentary behavior might make anxiety worse.
For instance, endorphins, which are released during aerobic activities like swimming or running, can help reduce anxiety.

Poor Diet: Processed foods and sugar-rich diets can have an impact on mood and brain function. (Nutritional Neuroscience)

Chronic sleep deprivation impairs emotional control and makes people more susceptible to worry.
For instance, the body’s stress reaction is heightened when restorative sleep is not possible.

5.Cultural and Social Influences

Cultural Norms and Expectations: Anxiety can result from social pressure to fit in or achieve.
For instance, social anxiety may arise in collectivist cultures as a result of the dread of disappointing family members.

Digital Overload: Stress and anxiety levels might rise as a result of the continuous barrage of information and social comparisons on digital platforms. (JMIR)

6.Physical Health Conditions

Chronic Illnesses: Because of ongoing health problems, conditions including diabetes, heart disease, and asthma are frequently linked to increased anxiety levels.

Substance Abuse: Reliance on drugs, alcohol, or caffeine can exacerbate or cause anxiety symptoms.(Journal of Anxiety Disorders)

7.Environmental Toxins and Climate Factors

Pollution and Toxins: Neurotoxic chemicals and air pollution can alter brain function, raising the risk of anxiety.
Climate Change Anxiety: Chronic concern is exacerbated by growing awareness of environmental crises around the world, especially among younger generations. (American Psychologist)

Targeted prevention and treatment efforts are made possible by an understanding of the complex elements that contribute to anxiety. Understanding how biology, environment, and lifestyle interact is crucial to creating comprehensive strategies for successfully managing anxiety.

Treatment of Anxiety

1.Pharmacological Treatment

The main factor influencing the choice of a specific medicine class or combination that is appropriate for treating anxiety is the patient’s level of bravery. In the behavioral modification and treatment, the level of anxiety experienced by the patient, the knowledge of the doctors, and the behavioral therapist. Other factors include comorbid diseases and the way the patient reacts to treatment.

First-Line Drugs

(i). Selective Serotonin Reuptake Inhibitors (SSRIs) : When SSRIs are insufficient, the patient should switch to clomipramine; augmentation can be achieved with low-dose antipsychotics (aripiprazole, risperidone) and low-dose anticonvulsants (pregabalin, lamotrigine). These medications increase the amount of serotonin in the synapses by blocking the reuptake of serotonin (5HT) by presynaptic neurons. When SSRIs are insufficient, the patient should switch to clomipramine; low-dose antipsychotics (risperidone, aripiprazole) and low-dose anticonvulsants (pregabalin, lamotrigine) might be used for augmentation.

(ii). Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): They work by preventing the presynaptic neuron from reabsorbing serotonin and norepinephrine, which raises their concentration at the junction. In patients with panic disorder, the anxiolytic effects of this class of medications may manifest in 2-4 weeks.

Second-Line Drugs

(iii). Tricyclic Antidepressants (TCAs): They work by blocking the transporters of serotonin and norepinephrine, which stops them from being reabsorbed and raises their concentration at the synapse. This increases neurotransmission. Effectiveness: Tricyclic antidepressants work well for agoraphobia and panic disorder. When treating OCD, clomipramine is the medication of choice when SSRIs or SNRIs didn’t work.

(iv). Benzodiazepines (BDZ): They work by attaching to and turning on the GABAA receptor, which causes GABA to attach to its receptor, the chloride ion channel opening, and the chloride ion entrance that results in cellular inhibition. Their effects can be observed within 1-2 minutes of ingestion because they have a far shorter onset than all other kinds of antianxiety medications.

Third-Line Drugs

v). Monoamine Oxidase Inhibitors (MAOIs): Effective in treating social anxiety disorders and panic disorder

(vi). Reversible Inhibitors of Monoamine Oxidase (RIMA): Moclobemide
is helpful in treating social anxiety disorder.

(vii). Atypical Antipsychotics (Second-generation antipsychotic): Quetiapine, Olanzapine, Risperidone,
Aripiprazole. Quetiapine is helpful in treating GAD at the dose of 50 to 300mg/day, panic disorder, and OCD, while risperidone is given at a dose of 0.5-2mg/day.

(viii). Azapirones: The buspirone work activates the 5-HT1A-serotonergic receptor or blocks the D2-dopaminergic receptor.

(ix). Anticonvulsants: OCD, panic disorder, Patients taking these drugs may be relieved of anxiety symptoms within 24hours.

(x). Antihistamines: Treatment of GAD.

Medicinal Plants Available to us Used in the Treatment of Anxiety

(i). Valeriana Officinalis (Valerian Extract): Previously used to treat anxiety, this plant had negative side effects such as headaches and GIT disturbances.

(ii). Lavandula angustifolia (Lavender Oil): This oil has been used to treat GAD with equivalent efficacy to lorazepam.

(iii). Hypericum Perforatum (St John’s Warts): This plant’s extract was once used to cure anxiety, but it didn’t work; side effects include weight gain, impotence, and suicide.

(iv). Passiflora Incarnata (Passionflower): It treats anxiety with similar effectiveness to BDZ; side effects include drowsiness, sleepiness, can raise the blood pressure.

(v). Galphimia Glauca (Extract): Another helpful phytomedicine for GAD is this extract, which has been shown to be just as successful in treating the condition as lorazepam in a randomized controlled clinical trial.

(vi). Piper Methysticum (KAVA): Originally used to cure anxiety, this herb was eventually removed because of its hepatotoxic sedative properties.

Non-Pharmacological Treatment: Strategies to beat anxiety: How to calm anxiety

1.Electroconvulsive Therapy: This entails placing a tiny electrode while using stereotactic MRI monitoring. Brief electrical shocks will induce neuronal firing and be used to treat mood disorders, panic attacks, and agoraphobia.

2.Vagal Nerve Stimulation: In order to treat panic disorder and agoraphobia, this entails stimulating fear control regions like the amygdala, hippocampus, insula, and frontal cortex via afferent vagal nerves to produce an inhibitory neurotransmitter.

3.Surgery: This is true for social phobia and resistant GAD. These consist of limbic leucotomy, anterior capsulotomy, subcaudate tractotomy, and anterior cingulotomy.

4. Cognitive Behavioral Therapy (CBT): CBT is generally a very important part of treating anxiety; in the case of panic disorder, it is more crucial than medication. The cognitive behavioral therapy (CBT) component used to treat panic disorder consists of coping mechanisms, exposure to the panic-inducing environment, altering negative thinking, and psychoeducation. CBT can be done once a week for a few hours for up to 12 to 16 weeks, however daily one-hour sessions were more successful.
