For example: bride feels anxious before her wedding,athletes feel anxious before important competition.Unlike this temporary feeling, anxiety disorder does not go away easily. Biological theory about Anxiety Disorder Every child has different temperament from birth. It remains as an adult, whether a baby is sensitive to stress or not. People that has a sensitive temperament are most likely to develop Anxiety Disorders due to their poor nervous system. There are genetic characteristic that determines one’s personality. One such characteristic is neuroticism. It defines person’s stability of emotion. For instance, a people that has high neuroticism could take bad test score as the reason of their failure in life. People that has low neuroticism, in the other hand, would feel disappointed if they got a bad grade, which will encourage them to study harder for the next test. Simply stated, people with high neuroticism are more sensitive to stress comparing to the people with low neuroticism.The human body physiology consists of 10 inter-related organ systems. More than half of these 10 systems are involved in production of anxiety and fear. 1.The nervous system; 2.The cardiovascular system; 3.The respiratory system; 4.The digestive system; 5.Endocrine system; 6.The excretory system, These six systems are responsible for the physiological, electrical, and chemical changes that causes anxiety in human body. The nervous system controls the whole body. Before we study more about anxiety disorder it is important to know that actions of the other systems are all controlled by nervous system. When a brain sends a signal to other systems to do an action, the signal passes all the connections of the neuron in just a few seconds.When the brain receives the information that the body is in danger, it automatically sends the anxiety, fear signals through the body and prepares the body for protective action.The part of the brain Hippocampus is responsible for memory function. During anxious arousal, the hippocampus is activated. The hippocampus involvement suggests that previous experiences and memories of those experiences, can initiate or increase anxiety symptoms.The cardiovascular system: When anxiety occurs in human body, the body requires oxygen to fuel muscle. To pump blood through the body, the heart needs to work more faster.  The anxiety symptoms that people describe include chest pain as if they were having a heart attack. However, some parts of the body needs more oxygen than other parts. Human body is efficient with fuel. Therefore, it reacts by restricting blood flow to areas that do not need it as much . Blood flow is redirected to areas where it is needed the most. Because of these actions, our extremities can become cold, or feel tingly. This is because they are not getting the usual amount of blood flow.The respiratory system: Since the heart is working harder to increase blood flow to carry more oxygen, the respiratory system must do its part by working harder to increase the amount of available oxygen. Respiration must increase. The additional oxygen provides the necessary energy to fuel the muscle cells. The increased respiration gets extra energy to those muscles fast! It produces a feeling of being out-of-breath, or being unable to get enough air. It can also cause tightness in the chest, and contributes to feelings of lightheadedness.The excretory system: In addition to increasing respiration and heart rate, the SNS also causes the body to perspire. Believe it or not, perspiration has several very protective functions. First and foremost, it operates as the body’s air conditioning system. It cools the body down so that it does not overheat. The by-product of muscles working very hard (including the heart muscle) is the generation of heat. Perspiration allows this additional heat to dissipate.Classification of Anxiety Disorder1.Generalized Anxiety DisorderPhysical symptoms:-Fatigue -Trouble sleeping-Muscle tension or muscle aches-Trembling, feeling twitchy-Nervousness or being easily startled-Sweating-Nausea, diarrhea or irritable bowel syndrome-IrritabilityPsychological symptoms:-Persistent worrying or anxiety about a number of areas that are out of proportion to the impact of the events-Overthinking plans and solutions to all possible worst-case outcomes-Perceiving situations and events as threatening, even when they aren’t-Difficulty handling uncertainty-Indecisiveness and fear of making the wrong decision-Inability to set aside or let go of a worry-Inability to relax, feeling restless, and feeling keyed up or on edge-Difficulty concentrating, 2. Panic disorderPanic disorder is diagnosed in people who experiences unexpected panic panic attacks and are very aware of up-coming attacks. Panic attacks are often unforeseen. It can hit anytime. Panic disorder commonly, occurs young adults, but little children can also be diagnosed with panic disorder.Approximately 2-3% of Americans goes through panic disorder in some part of their lives. According to the survey, women are more in risk to occur panic disorder than men.Physical symptoms: -Shortness of breath-Heart palpitations-Chest pain or discomfort-Trembling or shaking-Sweating -Feeling dizzy, light headed3.Social Anxiety DisorderSocial Anxiety Disorder, or Social Phobia is extreme anxiety or awareness of what people would think. People with Social Anxiety Disorder, often times avoid not to get into a social situations. Even though they know their fear about social life is complete unreasonable, they feel weak against their anxiety. In America, there are 15 million adults who diagnosed with Social Anxiety Disorder. Social Anxiety Disorder often times starts at early teenage years. People with Social Anxiety Disorder ignores the opportunities. For example: Individuals may not attend college, because if they attend they will need to communicate with people. They may avoid going to grocery store due to a fear that they will have to interact with cashier.
