Some research suggests that your body's natural fight-or-flight response to danger is involved in panic attacks. For example, if a grizzly bear came after you, your body would react instinctively. Your heart rate and breathing would speed up as your body prepared for a life-threatening situation. Many of the same reactions occur in a panic attack. But it's unknown why a panic attack occurs when there's no obvious danger present.
Medications are also a common form of treatment for Generalized Anxiety Disorder. The most common types of medications prescribed to individuals living with this form of anxiety include anti-depressants, anti-anxiety drugs, and in some cases, sedatives. Antidepressants are used to treat depression, but have been found effective in the treatment of anxiety as well. They commonly take a couple of weeks to start taking effect and may cause some mild side effects, including headache, nausea, or difficulty sleeping. Most of the side effects are mild and tend to subside within a few weeks. Anti-anxiety medication is also often prescribed to help individuals cope with Generalized Anxiety Disorder. These types of drugs are powerful in their treatment of this type of anxiety; one of the most commonly prescribed types is a drug called buspirone often under the brand nane Buspar.
But flashbacks may occur with other types of anxiety as well. Some research, including a 2006 study in the Journal of Anxiety Disorders, suggests that some people with social anxiety have PTSD-like flashbacks of experiences that might not seem obviously traumatic, such as being publicly ridiculed. These people may even avoid reminders of the experience—another symptom reminiscent of PTSD.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
