Anxiety is usually caused by an interaction of a number of factors, ranging from genetic predispositions, environmental factors, psychological states, to neurological factors. Genetics can play a major role in predisposing some people to developing anxiety disorders, while environmental factors, such as experiences of trauma, financial struggles, or work-related stress, can play a role in triggering or worsening the symptoms that people present. In addition, chemical imbalances in the brain, especially involving primary neurotransmitters like serotonin and dopamine, play a role in contributing to determining the setting of mood and how the body responds to stress. Along with these factors, some personalities, like perfectionism tendencies or excessive worry patterns, can also play roles in contributing to developing heightened levels of anxiety in a person. Repeated episodes of anxiety are therefore caused by complex interactions of such diverse factors and therefore are not uniform from person to person, illustrating the complex and intricate nature of the condition.
