Dynamics of Anxiety

Anxiety is a complex condition with psychological, biological and environmental factors causing predisposition to stress.

Psychological Factors

psychodynamic theories

Anxiety is a central concept in psychoanalytic conceptions of abnormal behaviour. According to Sigmund Freud, anxiety-based disorders, or neurotic disorders, are called neuroses. Psychodynamic Theory is a concept that explains a person's personality in terms of conscious and unconscious ways such as unconscious desires and beliefs.

Freud said our personality develops from the interactions of three fundamental structures of the human mind: the id, ego, and superego. Our efforts to find balance among the conflicts and desires of these structures determine our behaviour and approach of the world. The way we balance any situation determines our manner of resolving a conflict between two overreaching behavioural tendencies: our biological aggressive and pleasure-seeking drives vs. our socialised internal control over those drives.

Psychoanalysts believe obsessions and compulsions as ways of handling anxiety. According to Freud, obsessions are symbolically related to, but not as terrifying, as the underlying impulses. A compulsion is a way of taking back or undoing one's unacceptable urges, as with obsessive thoughts of dirt and compulsive handwashing are used to deal with one's dirty sexual impulses. Generalized anxiety and panic attacks are believed to occur when one's defences are too weak to control or contain neurotic anxiety, but strong enough to hide the underlying conflict.



The Id
The id is the most primitive form of the three structures; its only concern is of instant gratifications of its physical urges and needs. Its behaviour is entirely unconscious; outside of unconscious thought, for example; if it saw someone having something it likes, it would grab it for itself without knowing or caring that it's being rude. Its only concern would be of itself.

The Superego
The superego cares about social rules and morals, similar to what some people call a moral compass or conscience. This develops as a child considers right and wrong according to its cultural background. For this reason, unlike the id, the superego wouldn't take what's not belonging to it even if it needs it as it would be rude.

On the other hand, if both the id and the superego were involved and the id was strong enough to override the super ego's moral compass, it would take what it wants with no knowledge or concern about being rude but would feel shame and regret in the aftermath.

The Ego
The ego; in contrast to the id, who is all instinctual and superego, who is all about morals; is the rational pragmatic part of our personality. It's less primitive than the id and is partly conscious and unconscious. This is what Freud considered to be the 'Self'.

The ego's job is to balance the superego's and id's demands in a practical sense of reality. In the sense of the conflict between taking or not taking another person's thing, the ego would decide to buy what he needs instead. While this takes more time, the ego decides to make the sacrifice as an effort of compromise, which is satisfying your need for the thing you desire without taking part in an unpleasant social situation that could make you feel regret and shame in the aftermath.

Freud believed that the ego, superego, and id were constantly in conflict, resulting in adult personality and behaviour being rooted as a result of these internal struggles throughout childhood. Freud believed that a person with a strong ego has a healthy personalityand that imbalances in this system can cause neurosis (now thought as anxiety and depression, as well as certain unhealthy behaviours).

Cognitive Factors

Cognitive theorists stress that maladaptive thought patterns and beliefs associated with anxiety tend to magnify a situation worse than it is, causing people with anxiety to anticipate the worst outcome and making them powerless to cope effectively. Invasive thoughts about previous traumatic events are the main feature of posttraumatic stress disorder (PTSD). The presence of these thoughts after a traumatic event predicts later development of PTSD.

Cognitive processes play an important role in panic disorders. According to David Barlow, panic attacks are triggered by exaggerated normal misinterpretations of normal anxiety symptoms such as dizziness, heart palpitations, and breathlessness. A person misinterprets these as signs as a pending heart attack or psychological loss of control, creating more anxiety which spirals out of control, causing a full-blown panic attack. Helping panic-attack patients realize that it's just a bit of anxiety and not a heart attack can reduce the patient's anxiety and in turn, reduce panic-attacks.



The Role of Learning

From a behavioural perspective, classical conditioning observational learning or operant conditioning can contribute to the development of an anxiety disorder. Some fears are associated with traumatic experiences, which is a classical fear of response for a person who has had a traumatic experience like a fall from a height or almost drowning, which could cause fear of heights, or getting into a pool or other source of water.

However, classical conditioning cannot be the only case; there are people who have never been in a plane crash that are afraid of flying and people who have never had a bad fall, but fear heights (observational phobia). Seeing a random plane crash could trigger a fear in some people like some are afraid of spiders although they have never been bitten or there aren't any poisonous spiders in their counties. 

Yet, most people don't develop phobias through observation. It could be a biological and cognitive fact that causes some to develop phobias from observing or hearing while others don't. Once anxiety is learnt classically or vicariously, it could be triggered by cues from the environment or internal cues such as thoughts and images. In phobic reactions, the cues tend to be external, relating to feared objects or situations; whereas in panic disorders, the cues to the arousal of anxiety are internal bodily sensations such as one's heart rate, mental images of collapsing, and having a seizure in a public place.

In addition to classical conditioning and learning, operant conditions also play a role in motivating people with anxiety to avoid or escape it due to the unpleasant emotional state behaviour successful in reducing anxiety such as compulsions, or phobic avoidance responses become stronger through negative reinforcement.


Sociocultural Factors

Social and cultural factors can play a role in anxiety disorder development. The role of culture is not shown in culture-bound disorders that only occur in certain locales. One such phobia is found in Japan called 'Tianjin Kyofushu'. People affected by this disorder are pathologically frightened of offending others by emitting offensive odours, staring inappropriately, blushing or having a blemish, or improper facial expressions. This condition has been attributed to the Japanese cultural value of extreme interpersonal sensitivity and cultural prohibitions against expressing negative emotions or causing discomfort in others.

Another culture-bound disorder is 'koro'; a South-east Asian anxiety disorder in which a man thinks that his penis will retract into his abdomen and kill him. Western culture has culture-specific anxiety reactions too. Formally classified as an eating disorder, anorexia nervosa has a strong phobic component (fear of weight gain) and so also obsessive-compulsive elements. 

This eating disorder is mostly found in Western countries due to the cultural obsession of being thin. Causes of anxiety are complex and often interact with each other. These conditions can be viewed at biological, psychological, and environmental levels.

Anxiety Disorders

The anxious mind

Anxiety is a psychological disorder. We all tend to get anxious at some point in our lives; waiting for a test result of an underlying health condition, results from a college examination or job interview; any number of things can make us anxious, which is normal in stressful situations.
However, people with anxiety disorders tend to worry about everything. The slightest issue makes them anxious. People who do not understand this condition may ridicule the person who suffers from the disorder, causing them even more anguish.



For a person with anxiety, the frequency and intensity of response to problems are magnified. A person with anxiety gets emotional and tense easily. They tend to have worrying thoughts which make them unable to cope with life. It results in increased heart rate, the rise of blood pressure, rapid breathing, muscle tension, nausea, dry mouth, frequent urination and diarrhoea. There are behavioural changes too; they tend to avoid certain situations and lack task performance. Anxiety disorders come in so many different forms, and they are as follows:

  • Post-traumatic Stress Disorder (PTSD)
  • Obsessive-compulsive Disorder (OCD)
  • Panic Disorder
  • Generalised Anxiety Disorder (GAD)
  • Phobic disorders



The most common psychological disorder is GAD. People with anxiety disorders are affected throughout their life, while women are more likely to develop anxiety disorders than men. In many cases, anxiety disorders are considered clinically significant, which means that they interfere in a person's life, or cause them to seek medical or psychological treatment. Phobias are also a part of anxiety disorders.

What's a phobia?

phobias are irrational fears; be it a fear of an object or situation. People with phobias understand that their fears aren't natural, but their condition still makes them helpless, making it impossible for them to do anything about it. It's like knowing what to do yet being forced to do the opposite. All they can do is try their best to avoid the said object or situation.



The most common phobia is agoraphobia, which is the fear of public places where escape is improbable. Social phobia, which is a fear of being evaluated and embarrassed by others.
Specific phobias are fear of spiders, snakes, dogs, enclosed spaces, water, germs, injections, and heights. Phobias are mostly developed during childhood, adolescence, and early adulthood, but there is a chance of phobias arising later in life as well. According to the situation experienced, phobias rarely subside.

GAD


In most cases of phobia, they intensify with time. With frequent encounters of the said situation or object, the phobia tends to intensify, which is the reason they avoid such situations and objects. GAD is a chronic state of anxiety not attached to a specific situation or object. This anxiety can continue from weeks to months without any symptoms present. When affected by this disorder, it makes the person unable to concentrate, as well as make decisions and commitments.

Panic Disorder


Panic Disorder is unpredictable. Even when there is no identifiable danger, the patients can have panic attacks. This makes it terrifying as it can make them feel that they are on the verge of death. A panic attack can occur when the said person is asleep or wide awake. When it happens when the person is asleep, he or she can wake up, but find themselves unable to move or even speak. This is called sleep paralysis; the person is not actually paralysed but feels so. They fear that death has come to take them. This can be infuriating to the sufferer.

The fear of such panic attacks occurring keep them from leaving familiar surroundings; they often isolate themselves at home. Panic Disorder is diagnosed when recurrent attacks are not tied to any stimuli followed by psychological or behavioural issues caused by a persistent fear of future attacks or agoraphobic response. Panic Disorder emerges during adolescence or early adulthood, which may or may not accompany agoraphobia.



OCD

Obsessions, or unwelcome thoughts, images or impulses, often invade a person's consciousness and are hard to dismiss or control. This could make a person compulsive. As a result, this person will often repeat the same things; such as washing and cleaning, rechecking if the door was locked, or the stove was switched off over and over.
This helps relieve the anxiety caused by the obsessive-compulsion for a while, but not indefinitely. Being unable to perform this compulsive act can aggravate the person's anxiety, which can result in a panic attack. Therefore, it's best not to interfere and let this person carry on with their rituals. The onset of OCD starts when a person is in their 20's.

PTSD


PTSD is a severe anxiety disorder which occurs when a person is exposed to severe trauma. The symptoms are anxiety, distress and arousal that wasn't present before being exposed to trauma. This person tends to relive the trauma recurrently as dreams and flashbacks. The victim tries to avoid situations that stimulate anxiety by numbing themselves to the world.

This person tends to suffer from survivor's guilt, where he survived while others were killed. PTSD was first diagnosed in soldiers who survived the horrors of war; who had either been injured and or had lost their comrades. Civilians who had been subjected to war could be affected by PTSD as well. Compared to men, women's levels of PTSD is higher when exposed to traumatic events. The psychological issues caused by PTSD can result in other psychological disorders as well. Women have a higher chance than men to develop depressive disorders and alcoholism when suffering from PTSD.
