Psychological And Neurobiological Models Of Anxiety

Today anxiety disorders are recognized as one of the most common mental health disorders. Anxiety has been around since human’s worried about being eaten by saber tooth tigers. “It’s important to note that at its core level, anxiety is a part of evolution. Anxiety is the activation of the fight or flight system the system your body uses to keep you safe from harm (Calm Clinic)”. Oddly, anxiety is a normal part of life; you may feel anxious when having to make a significant decision or taking a test, for most people these normal feelings usually fade, however for those who suffer from an anxiety disorder, these feels never subsides. They can cause such distress that it interferes with an individual’s ability to lead a normal healthy life.

Anxiety disorders is the most common psychiatric disorder characterized by unrealistic, unfounded fear, and anxiety in which perhaps possible related to the thoughts and concerns about the current or future events. Long episodic attacks of acute anxiety can cause a panic attack and eventually lead to a panic disorder. This paper examines the panic disorder and its biological foundation that relates with the disorder and symptoms.

Alternatively Hadley (1995) puts forward the view that contrary to popular belief, anxiety actually arises out of thoughts of potential danger and not the actual danger that produces the symptoms of anxiety. In support of this view the document by Chrysalis states that “feelings of anxiety come from apprehension or fear, the source of which is not always recognisable”. Feeling anxious at certain times in our life is a normal instinctual response that serves as a protection to aid survival. It teaches us to avoid dangerous situations and in this way is a learning process however the subconscious can sometimes work overtime resulting in response to all situations that feel remotely similar to the one that has made us feel anxious in the first instance (Chrysalis 2010 1-5 pp7). This document describes how anxiety will affect our whole being, our emotions, our behaviour and our physical health. Anxiety becomes a problem when its level rises above normal and interfere with a person’s life, associated physical symptoms include, trembling, tense muscles, churning stomach, nausea, diarrhoea, headache, heart palpitations, pins and needles, sweating or flushing (Chrysalis 2010 1-5 pp7). These feelings coupled with the physical symptoms experienced make a person want

The first major controversy concerning classifications of mental disorders is the debate over dimensions vs. categories. According to the APA (2000), DSM–IV is a categorical classification that divides mental disorders into types based on criterion sets with defining features. Categories have been utilized in the past DSMs, however there has been much debate on changing to the dimensional model. The debate stems from the notion that in order for a categorical diagnosis to relate specifically to a disorder, the pathology would have to have been largely resilient to the influence of many other genetic and environmental influences (Widiger & Sankis, 2000). On the contrast, utilizing the dimensional model for a diagnosis would utilize a wide variety of neurochemical, interpersonal, cognitive, and other mediating and moderating variables that help to develop, shape, and form a particular individual’s psychopathology profile (Andreasen, 1997).

To experience any form of anxiety, such as interviews, a drive in traffic, or even a first date is a natural- human experience. For instance, one begins to undergo a feeling of failure regarding specific class. Nevertheless, sometimes, the emotion, keeps us motivated and school work-orientated. Yet, now and then, anxiety can take a hold on one when intense fear and distress becomes too overwhelming; it can prevent one from doing everyday thing. As a result, anxiety disorder can be the cause (B. T. Anxiety Disorders, 2016). According to National Alliance of Mental Illness, known as NAMI (2016), anxiety disorders are a common mental health concern in the United States. Roughly, forty million adults in the United States, and eight percent of children and teenagers face some sort of a negative impact of an anxiety disorder. Consequently, people develop symptoms of anxiety disorder before the age twenty-one.

Science with all its marvels and wonders continues to press forward making extraordinary breakthroughs. Psychology plays a key role in many of sciences steps forward, each branch of psychology focusing on a specific techniques and theories. In the document the center of attention is surrounding the application of clinical psychology, this branch of psychology is unique as it all realms of an individual’s issue. Specifically speaking, anxiety is the psychological disorder that is under review through the processes of a clinical

In 2013, the National Institute of Mental Health (NIMH) broadly launched the Research Domain Criteria project (RDoC). The purpose of RDoC is to provide a working framework to advance dimensional approaches of classifying psychopathology on the basis of observable behaviors and neurobiological measures (National Institute of Mental Health, 2013). Reflecting on the last thirty years, incredible progress has been made in understanding brain-behavior relationships in numerous mental disorders. The continued interdisciplinary work of geneticists, cognitive and affective neuroscientists, and behavioral researchers has not only expanded our knowledge of biological causal and maintenance factors, but has also provided the field with a strong

Many people have anxiety. Anxiety disorders are the most common of all mental disorders. There are many different types of anxiety: Generalized, Panic, Social Phobia, Obsessive Compulsive, Post-Traumatic, and Acute Stress. When facing a problem like this, first, we must understand the repressed feeling. Any of these types of anxiety can destroy any thought of preforming an action properly, speaking in public, a deadline, or running into someone. These actions may seem simple, but have a major impact on a person. Experiences of anxiety can come in many ways. When trying to overcome anxiety, we need to decide the cause, when the origin is known, the preparation can begin. I chose to refurbish a AR-15, and to fire the

A recent article from BigThink, written by Philip Perry, discusses a group of researchers who have found the source of anxiety within the brain. Mazen Kheirbek, Ph.D, the head researcher of this study, stuck a miniature microscope in the brains of mice in order to find what he is now calling “anxiety cells”. Kheirbek put the mice in strenuous situations that would cause them to have anxiety, he then looked for the part of the brain that had the most activity; thus he was able to find the location of the cells. This new discovery is a big step in creating better medications for anxiety sufferers. Current anxiety medication prescribed by physicians are only partially effective at controlling anxiety; Kheirbek states that medication that can

Anxiety Disorder is a sudden feeling of qualms, uneasiness, nervousness, and anxiousness. Symptoms vary for each person. In the adolescent years anxiety shines the most. With school work, and social interaction. In our society, many people diagnose themselves with anxiety, because they are nervous, they believe they have an anxiety disorder. In the adolescent years anxiety is there, but usually mild, in today’s society, because studies show that anxiety has increased over the years. The denotation of anxiety is a sudden feeling of sickness, apprehension, paranoia. Eager and anxious are often used incorrectly, using the opposing one as the other. Anxiety means anticipation of an impending event. However, eager implies that the person looks

What makes the anxiety vary from fear is that it is not focused on a specific event or object, and the person is not aware of the cause of unpleasant emotions. Depressing feeling, mood state, helplessness, hopelessness, followed by feelings of guilt, sadness, inadequacy is also affective reactions. Similarly anxiety that is experienced as a feeling of fear, but without an objective danger, depression is most easily be understood as a feeling of sadness, grief, for no apparent reason.

Most psychopathology research to date is guided by the conceptualization of psychopathology adopted by the current nosological systems, the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD). These nosological systems conceptualize mental disorders as discrete categorical entities. In these diagnostic manuals, several categories of mental disorder are listed, the membership in which depends on whether an individual meets a number of suggested criteria (APA, 2013; WHO, 2016). Thus, an individual is either a member or nonmember of these categories (Krueger & Markon, 2006a). The DSM-5 acknowledged the limitations of this approach and provided several assumptions that needed to be

When someone is under-anxious they cannot respond accordingly to ensure survival in a stressful event. On the other hand, when over-anxious, there may be a false alarm, but this would ensure survival. Signal-detection theory has noted that even though anxiety can come about from harmless stimuli and lead to wasted resources, the times when something is harmful need not to be missed in order to ensure survival (Stirling, Greskovich, & Johnson, 2014). It is important to analyze the basic premise of this theory. It suggests that people are prone to be anxious of harmless stimuli. Even though there are advantages to this, it can lead to “disorders that share features of excessive fear and anxiety and related behavioral disturbances,” otherwise called anxiety disorders by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association,

The theorist Karen Horney was the first person to develop the idea of basic anxiety. Having her own personal struggles with being rejected of affection aided her thought of social development, yet paving the way for new developmental theories of personality. The impact Horney had on the discipline of psychology was enormous. Horney not only inspired women psychologists, but also created a new place in the world where women had the right to their own ideas.
