Anxiety can be either a short-term 'state' or a long-term personality "trait". Trait anxiety reflects a stable tendency across the lifespan of responding with acute, state anxiety in the anticipation of threatening situations (whether they are actually deemed threatening or not).[40] A meta-analysis showed that a high level of neuroticism is a risk factor for development of anxiety symptoms and disorders.[41] Such anxiety may be conscious or unconscious.[42]
Since panic attacks are caused by overly apprehensive behavior or chronic stress, addressing our overly apprehensive behavior and stress can stop and prevent panic attacks, and eventually, panic disorder. The combination of good self-help information and therapy is the most effective way of addressing overly apprehensive behavior.[2] Accessing good self-help information and applying it is a good way to reduce stress.
Contextual factors that are thought to contribute to anxiety include gender socialization and learning experiences. In particular, learning mastery (the degree to which people perceive their lives to be under their own control) and instrumentality, which includes such traits as self-confidence, independence, and competitiveness fully mediate the relation between gender and anxiety. That is, though gender differences in anxiety exist, with higher levels of anxiety in women compared to men, gender socialization and learning mastery explain these gender differences.[90][medical citation needed] Research has demonstrated the ways in which facial prominence in photographic images differs between men and women. More specifically, in official online photographs of politicians around the world, women's faces are less prominent than men's. The difference in these images actually tended to be greater in cultures with greater institutional gender equality.[91]

"Anxiety" is a general term that describes a variety of experiences, including nervousness, fear, apprehension, and worry, that are common in several mental health disorders. While most of us have anxiety at some time, this is completely different from an anxiety attack or anxiety disorder. Normal feelings of nervousness, worry, and fear often have a known trigger (a major exam, money issues, or seeing a bug). But when you're having a full blown panic attack or anxiety attack, the symptoms — chest pain, flushing skin, racing heart, and difficulty breathing — can make you feel as though you're going to faint, lose your mind, or die. The reality is, you won’t. The key to surviving is to learn all you can about anxiety attacks and practice the skills you need to get through them.
Biological causes may include obsessive compulsive disorder, Postural Orthostatic Tachycardia Syndrome, post traumatic stress disorder, hypoglycemia, hyperthyroidism, Wilson's disease, mitral valve prolapse, pheochromocytoma, and inner ear disturbances (labyrinthitis). Dysregulation of the norepinephrine system in the locus ceruleus, an area of the brain stem, has been linked to panic attacks.[13]
In people with anxiety disorders, the brain circuitry that controls the threat response goes awry. At the heart of the circuit is the amygdala, a structure that flags incoming signals as worrisome and communicates with other parts of the brain to put the body on alert for danger. Early life events, especially traumatic ones, can program the circuitry so that it is oversensitive and sends out alarms too frequently and with only minor provocations. Survival mandates a system for perceiving threats and taking quick, automatic action, but those with anxiety see threats where there are none, perhaps because emotional memories color their perceptions.
Occasional anxiety is an expected part of life. You might feel anxious when faced with a problem at work, before taking a test, or before making an important decision. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, school work, and relationships.
