What cam cause anxiety ?

What are the reasons that cause anxiety disorders?

Cognition or the way of thinking:

Cognition or the way of thinking is playing an extremely important role in the formation of the anxiety disorders. The study found that patients with anxiety disorders tend to treat the ambiguous or even the benign events as harbinger of the crisis. They are more inclined to think that bad things will fall into them, more inclined to believe that the failure awaits them and more inclined to underestimate their own ability to control the negative events than the average people.
Unexpected events:

It is more likely to cause anxiety disorder in the case of stress events. Thyroid hormone and noradrenaline and these tensions -related hormone secretion disorder (excess) amplified the above process.

Biological factors:

Although Somatic diseases or biological dysfunction are not the only reason which causes anxiety disorders, in some rare cases, the patient's anxiety disorders can be caused by physical factors, for example, hyperthyroidism , adrenal tumors. Many researchers have tried to find if the central nervous system, especially some kind of neurotransmitter is the chief culprit which causes the anxiety disorders.

Many studies have focused on the two neurotransmitters: norepinephrine and serotonin. Many studies have found that the levels of norepinephrine and serotonin in patients' brains are dramatic changing when they are in the state of anxiety. But the changes are the reason or result of the anxiety disorders is not confirmed.
