Aygun Badalova

Anxiety disorders are one of the most wide-spread and concerning diseases around the globe. Nowadays many people suffer from different types of anxiety disorders worldwide which decreases the quality of life and productivity significantly. (Medlovic et al) According to the WHO, almost one in thirteen individuals suffer from anxiety disorders which is quite concerning statistical proportion. Generally, anxiety is a natural feeling of human beings, is a typical reaction to danger, the body’s automatic fight-or-flight response that is triggered when one feels threatened, but it becomes a disorder when it hurts, disturbs or leads to suffering. Over the past years, numerous neuroimaging studies have been carried out specially dedicated to the progress of understanding the neural circuitry of anxiety disorders (Bremner 2004). Therefore, more recently, the main focus on the diagnosis of anxiety disorders has been the usage of neuroimaging techniques that will be further discussed in more detail.
