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). A meta-analysis showed that a high level of neuroticism is a risk factor for development of anxiety symptoms and disorders. Such anxiety may be conscious or unconscious.
Psychologically, people who develop panic attacks or another anxiety disorder are more likely to have a history of what is called anxiety sensitivity. Anxiety sensitivity is the tendency for a person to fear that anxiety-related bodily sensations (like brief chest pain or stomach upset) have dire personal consequences (for example, believing that it automatically means their heart will stop or they will throw up, respectively). From a social standpoint, a risk factor for developing panic disorder as an adolescent or adult is a history of being physically or sexually abused as a child. This is even more the case for panic disorder when compared to other anxiety disorders. Often, the first attacks are triggered by physical illnesses, another major life stress, or perhaps medications that increase activity in the part of the brain involved in fear reactions.
Certain traumatic events can eventually cause someone to develop panic disorder. For example, therapist Shannon Nuñez, who is also the Clinical Director at the Pathway to Hope addiction treatment center, has worked with clients who developed panic disorder after witnessing sudden deaths. Witnessing a sudden death can make people feel like they could die in a moment and at any time, causing panic attacks.
With regard to environmental factors within the family, parenting behavior can also impact risk for anxiety disorders. Parents who demonstrate high levels of control (versus granting the child autonomy) while interacting with their children has been associated with development of anxiety disorders. Parental modeling of anxious behaviors and parental rejection of the child has also been shown to potentially relate to greater risk for anxiety. Experiencing stressful life events or chronic stress is also related to the development of anxiety disorders. Stressful life events in childhood, including experiencing adversity, sexual, physical, or emotional abuse, or parental loss or separation may increase risk for experiencing an anxiety disorder later in life. Having recently experienced a traumatic event or very stressful event can be a risk factor for the development of anxiety across different age groups. Consistent with the notion of chronic life stress resulting in increased anxiety risk, having lower access to socioeconomic resources or being a member of a minority group has also been suggested to relate to greater risk.
Signs of mental health difficulty can be different in the workplace than in other settings. The Harvard Mental Health Letter outlines signs that you may notice in your co-workers, which could indicate a significant problem. For anxiety disorders, these can include restlessness, fatigue, difficulty concentrating, excess worrying, and a general impairment in quality of work.
Anxiety disorders are associated with chronic life stress. Unpredictable, unrelenting, unresolvable stressors chronically stimulate the stress hormone system and cardiovascular system, and lead to states of constant increased activity. Biologically, the body has evolved to deal with imminent and concrete danger in the environment, rather than continuous stressors. Under normal conditions where chronic stress is low, exposure to a sudden threat activates the autonomic nervous system, i.e. increased levels of adrenaline and faster breathing, and racing heart rate. These reactions in turn trigger activation of stress hormones, such as cortisol. One of the effects of these stress hormones is to increase glucose levels in the bloodstream in order to respond to the imminent threat, so that muscles can be activated for the flight or fight response. Another effect of stress hormones is to supress the immune system, since processes such as healing and repair can wait until after the threat subsides. However, in someone with an anxiety disorder, where there is constant activation of these responses to everyday stressors, the stress hormone system loses its ability to control immune function, thus contributing to heightened systemic inflammation that increases risk for cardiovascular and even autoimmune disorders. Neuroscience and clinical research continues to investigate how anxiety disorders increase individual risk for developing physical health co-morbidities in hopes of identifying new treatments that may alleviate suffering from and prevent the development of these whole-body disorders.
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.
