Anxiety Type

Each person experiences a vague, obnoxious diffuse sense of apprehension, often accompanied by headache, palpitation, sweating, stomach discomfort, chest tightness, and even irritability. This is called anxiety, an alerting reaction to an unknown and internal threat. Serving as a warning sign for an external or internal threat, it aids a person for survival thus, preventing one from pain, damage to organs, punishment/sanctions, and frustrating situations like separation from relatives and loved ones, and decline in social status. This brings about the necessary action to avoid or diminish the possible outcomes. Therefore, anxiety helps a person from damage and further dangers.


Anxiety disorders are the most prevalent group of psychiatric cases. Women are reported to have higher prevalence compared to men and overall prevalence is noted to be lower in higher socioeconomic status.


Several explanations contribute on the causes of anxiety. Psychological theories like the Psychoanalytic, Behavioral and Existential theories, the Biological theories on the Nervous System and Neurotransmitters (Norepinephrine, Serotonin and Gamma Amino-Butyric Acid). Genetic studies also have contributed information on gene components that contribute in developing anxiety disorders which just supports the association of anxiety patients having at least one relative with anxiety disorder.  Based on modern brain imaging procedures such as the MRI, the Limbic System and the Cerebral Cortex are the specific sites of the Nervous System where much of the studies on anxiety were focused.


There are different kinds of anxiety disorders which will be discussed below.
