Great questions. Unfortunately, there is usually no clear cut answer – and like many mental health disorders – it is likely caused by a combination of genetic, behavioral, and developmental factors. Anatomically speaking, Generalized Anxiety Disorder is most closely related to a disruption in the functional connectivity of the amygdala – the “emotional control center” of the brain – and how it processes feelings of fear and anxiety. Genetics also play a role in Generalized Anxiety Disorder. If you have a family member that also suffers from this disorder, your chances of suffering from it are increased, especially in the presence of a life stressor. Interestingly, long-term substance abuse also increases your chances of Generalized Anxiety Disorder, as the use of benzodiazepines can worsen your anxiety levels, as can excessive alcohol use. Tobacco use and caffeine are also both associated with increased levels of anxiety.
Although anxiety is often accompanied by physical symptoms, such as a racing heart or knots in your stomach, what differentiates a panic attack from other anxiety symptoms is the intensity and duration of the symptoms. Panic attacks typically reach their peak level of intensity in 10 minutes or less and then begin to subside. Due to the intensity of the symptoms and their tendency to mimic those of heart disease, thyroid problems, breathing disorders, and other illnesses, people with panic disorder often make many visits to emergency rooms or doctors' offices, convinced they have a life-threatening issue.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
Some people with anxiety disorders might benefit from joining a self-help or support group and sharing their problems and achievements with others. Internet chat rooms might also be useful, but any advice received over the internet should be used with caution, as Internet acquaintances have usually never seen each other and what has helped one person is not necessarily what is best for another. You should always check with your doctor before following any treatment advice found on the internet. Talking with a trusted friend or member of the clergy can also provide support, but it is not necessarily a sufficient alternative to care from a doctor or other health professional.
Not getting enough restful sleep can trigger anxiety. Stress and anxiety can also interfere with sleep and cause you to stay awake at night. It can be a frustrating cycle when the stressors of the day and future worries cause you stay up at night. Take some time to wind down before bed such as utilizing some of the above relaxation and meditation strategies. Also, instead of letting your mind continuously race at night, try putting your thoughts, worries, and plans for the next day on paper before bed. This will ease your anxiety about forgetting something you need to accomplish in the future and allow you to relax and rest.
When we’re anxious, the body produces a stress response. The stress response is designed to give us an extra ‘boost’ of awareness and energy when we think we could be in danger. The stress response causes a number of physiological, psychological, and emotional changes in the body that enhance the body’s ability to deal with a perceived threat – to either fight or flee, which is the reason the stress response is often referred to as the ‘fight or flight response.’
