Fear - Causes, Symptoms, and Diagnosis

What Is Fear?

Fear is a natural, unpleasant emotional response that alerts us against physical or psychological danger. Although fear can be from a real threat or imagined danger, it can also present in mental health disorders like anxiety, phobias, and post-traumatic stress disorder. The amygdala is part of the brain that reacts to danger and tries to overcome it. A fearful response produces a biochemical and emotional reaction.

1) Biochemical Reaction: This reaction is the mechanism to prepare our bodies for the perceived or presumed threat; it can also be termed as a fight or flight mechanism of the body where a body prepares to either deal with the danger or run away to be at a safer place. The biochemical reaction can be visualized as sweating, increased heart rate, tremors, dilated pupils, increased respiratory rate, and tensed muscles. Adrenaline and cortisol are the hormones responsible for fear-fight reactions; these hormones are regulated and secreted by the hypothalamus and adrenal cortex. Biochemical reactions of everybody to fear are similar with varying intensities, unlike emotional reactions.

2) Emotional Reaction: Emotional response varies depending on every individual, as every person can react differently to the same stimuli. To describe this, one can consider a roller coaster ride an adventurous experience to some, whereas, for others, it can be a deadly fearful moment; so one can state that the adrenaline rush is enjoyable to few, whereas others try to avoid such situations.

What Are the Symptoms of Fear?

A fearful person would present with both physical and emotional symptoms, and these symptoms or reactions to fear would differ from person to person; some of the most likely symptoms are listed below.

What Are the Five Most Fundamental Fears?

• Extinction: Fear of death, or more simply, the fear of extinction or ceasing to exist. The fear stems from a concern for one's potential manner of passing away. Fear of heights, flying, the dark, and deadly illnesses are a few instances of extinction.

• Mutilation or Invasion of the Body: Fear of losing a body component or of pushing past the physical limits. Anxiety over becoming wounded or in any potentially fatal situation might result from this.

• Loss of Autonomy: Fear of being choked, suffocated, imprisoned, or trapped. This may be related to anxieties that are mental or physical, such as feeling suffocated, confined, overpowered, or imprisoned, or it may be related to situations that are out of one's control.

• Rejection, Abandonment, or Separation: Since humans are social animals, one of the greatest fears is often being alone. Examples include the inability to maintain a relationship or, in the event that one has lost the other, a variety of relationships, such as friendships, failed marriages, or the loss of a loved one.

• Shame, Humiliation, or Worthlessness: Also referred to as Ego-death, this fear is related to social settings and arises when a person feels ashamed of their actions in front of close friends and family. Events such as victimization, bullying, failure, criticism, or blunders made when public speaking might serve as the catalyst.

What Physical Effects Does Fear Have?

Despite being an emotional response to specific circumstances, fear can cause physical modifications in the body. The first thing the human body does is send a hypothalamic-pituitary-adrenal (HPA) alarm to alert the entire body to the threat. Cortisol, adrenaline, and noradrenaline are released, and the autonomic nervous system is activated, getting ready for the next phase. The second stage, resistance, restores damage from the brief period of stress and terror. It then aids in regaining energy. The third stage, tiredness, may occur if the issue is not resolved quickly.

What Are the Drawbacks of Having Fear?

Along with impairing the mental and physical faculties, fear also taints the psychology. In terms of physical well-being, fear can compromise immunity. When faced with fear, the majority of the bodily organs receive signals from the nervous system telling them to shut down and use all of their stored energy to deal with the situation.

Additionally, fear disrupts the brain's normal functions and reactivity. Additionally, it distorts judgment and thought processes, making a person more prone to impulsive and strong emotional reactions.

How Is Fear Diagnosed?

Fear, like other mental disorders, can be diagnosed and treated after reporting a detailed history. A patient must report to the psychiatrist if he is having repeated episodes of fear; a patient with repeated fear can also suffer panic attacks, which can be life-threatening; therefore, timely medical advice and attention are important. On consulting, a psychiatrist would thoroughly understand the history and conduct a physical examination and lab tests to rule out any interlinked underlying medical disorder.

During the investigation, a psychiatrist might question the incidents, situations, and places that trigger anxiety. The diagnosis can be made based on the information gathered, and further steps can be planned to prevent and combat the fear. Phobias are mostly correlated with fear and can be considered a differential diagnosis.

What Are Phobias?

A Phobia can be defined as a fear of fear; it is commonly seen in individuals who suffer from Lexan anxiety disorder. These people are often scared and think that some of the incidents would occur, which would be fearful, though it keeps them alert and anxious every time. Phobias often develop through repeated fearful experiences.

What Are the Causes of Fear?

Causes of fear differ from person to person, as some fear heights while others could fear a dark room. Fear in a broader spectrum can be termed as a perception of the event rather than an actual act, as people can fear closed spaces, heights, snakes, spiders, lizards, imagined events or objects, future events, etc. Fears are often developed over time and are mainly the result of traumatic experiences.

What Are the Types of Fear Disorders?

Various anxiety disorders are characterized by fear, some of which are listed below:

• Agoraphobia.

• Generalized anxiety disorder.

• Panic disorder.

• Post-traumatic stress disorder (PTSD).

• Separation anxiety disorder.

• Social anxiety disorder.

• Specific phobia.

How Is Fear Treated?

The treatment of fear is mainly based on the theory of familiarizing the fearful object. A person is repeatedly exposed to similar situations so that he is familiar with them, gets resistance, and does not fear.

Various techniques used in the treatment of fear include:

• Systematic presentation.

• Flooding.

These techniques function with the body’s physiological and psychological responses to overcome fear.

Systematic Desensitization:

This therapy aims to gradually expose one to a series of similar situations that are fearful. The objective of the therapy is to familiarize an individual with fearful objects to reduce the intensity of anxiety. For example, in this method, if a person fears the dark during the first appointment, the therapist discusses the dark and the fearful situation; during the second appointment, pictures of the same are shown to the person, and then the person is taken into dark rooms or on dark roads during consecutive appointments till he gets used to being alone in the dark.

Flooding:

It is a very effective treatment method that helps to overcome fear as an individual is repeatedly exposed to multiple fearful situations or objects for a prolonged time in a safe and monitored environment until the fear is overcome.

This treatment modality believes fear is a learned phenomenon that one can overcome. Though this is the most effective treatment method, it is advised to always carry out therapy under the guidance of a trained professional with the advice of a psychotherapist.

• Healthy eating habits.

• Regular exercising.

• Meditations.

• Seeking support and discussing concerns with the family and friends.

• Practice mindfulness.

• Replace fearful thoughts with positive ones.
