Main body- The Neurobiology of Anxiety Disorders Essay 

What is neurobiology?

The term “neurobiology” consists of two different worlds, which are “Neuro” and “biology“. Where the “neuro” refers to nerves and the nervous system. Whereas,  biology means the study of living organisms.

Consequently, the concept of “Neurobiology” concerns itself with the study of nerves and their organization in form of functional channels. These neurological channels enable information processing and meditation behavior. Thus, we can say that it is the study of the nervous system and the functioning of the brain.

Furthermore, it also concerns nerves’ function, the function of the brain, spinal cord, and so on. However, this field of study should not be confused with that of neuroscience. The reason being that “Neurobiology” is considered to be a sub-discipline or subset of neuroscience as well as physiology.

Moving on, we shall be looking at the definition and different forms of anxiety disorder in the next section of the sample essay.

What are anxiety disorders and types?

“Anxiety Disorders” are a specific disorder of psychiatric nature that usually involves severe fear, worry, stress, and so on. Meanwhile, anxiety is a normal human emotion and reaction to different stimuli. The scope of Anxiety Disorder is much larger. Reason being that it differs from the usual feeling of anxiety and involves extreme fear or anxiety.

Moreover, it is quite a common mental disorder that affects as much as 30% of all adults at one point in their lives. Apart from this, there are also several different types and forms of the same. These are:

• Generalized Anxiety Disorder
• Panic Disorder
• Specific Phobia
• Agoraphobia
• Social Anxiety Disorder
• Separation Anxiety Disorder

Despite the complex nature and severity of the disorder,  anxiety disorders are very much treatable. Regardless, we shall be moving on and looking at the causes of vulnerability to anxiety disorder in the next section of the sample essay.

What causes vulnerability to Anxiety Disorder?

Various clinical researches and observational studies through the stretch of time have found that anxiety disorder could possibly be hereditary in nature. In addition to this, multiple studies have shown that people have as much as double or triple time the risk of developing anxiety disorder if the same has been observed before in the family.

Moreover, there are several other internal contributing factors to this. For instance, personality traits may also cause vulnerability to anxiety disorder. Apart from this, external factors can affect can also be a leading cause. Thus, environmental factors also lead to anxiety in some cases. Plus, these factors also include exposure to stressful situations. This includes the use of drugs and alcohol, style of parenting, as well as another stressful event in one’s life.

Neuroanatomy of Anxiety

Here, we shall be looking at the “Neuroanatomy” of anxiety disorder. The term can again be divided into two separated words. Namely, “Neuro” and”Anatomy”. We already know the meaning of the former one, whereas the latter refers to the study of an organism’s structural organization. Thus, we can say that Neuroanatomy means the study of the brain’s and nervous systems’ biological structure.

Moreover, this system is hippocampus playing a crucial role in responding to stress. In addition to this, Hippocampal growth, as well as neurogenesis, are important in developing resilience against stress and anxiety.

Nevertheless, the most important part of this system which deals with the regulation of emotions is termed as “amygdala“. It is the point of focus for feelings of fear and anxiety-related memories. Hence, this part is shown to be hyperactive during anxiety disorders.

Furthermore, there are several Neuroanatomical changes related to anxiety disorder. We shall be discussing these changes in the next section of the sample essay.

Neuroanatomical changes in anxiety disorder

Anxiety disorders usually developed during childhood. These are caused by a long and continual feeling of anxiety and also cause changes in the brain’s structures of a person’s brain.

Moreover, there are higher levels of activity in the ventrolateral prefrontal cortex of the brain during generalized anxiety disorder. In addition, people who are asked to focus on stress show a high level of activity in the amygdala as well as significant changes in the cingular cortex and insular cortex.

Moving on,  there is extensive physical growth as well as behavioral, cognitive, and emotional changes during adolescence. Thus, changes in brain structure following psychiatric disorders have a tendency to become permanent. For the same reason, it is easier to correct the brain’s biochemical structure using therapeutic agents.

Conclusion: 

Anxiety disorders are common mental illnesses, but they can be treated. There is no need to suffer in silence. If you experience any of the symptoms listed above or have a loved one who does, please contact your physician for help today. Hope this essay example may beneficial for you.
