Benzodiazepines are often used to provide short-term relief of panic symptoms. Clonazepam (Klonopin) and lorazepam (Ativan) are examples of this group of medications. Although another benzodiazepine, alprazolam (Xanax), is often used to treat panic attacks, the short period of time that it works can cause the panic sufferer to have to take it multiple times each day. Benzodiazepines tend to be effective in decreasing panic attacks by up to 70%-75% almost immediately; however, this class of medications has a strong addiction potential and should be used with caution. Additional drawbacks include sedation, memory loss, and after several weeks, tolerance to their effects and withdrawal symptoms may occur.
In contrast, the term anxiety attack is not a specifier outlined in the DSM-5. Rather, anxiety is used to describe a core feature of multiple different anxiety disorders. The culmination of symptoms that result from being in a state of anxiety—such as restlessness, shortness of breath, increased heart rate, and difficulty concentrating—may feel like an “attack,” but are generally less intense than those experienced at the height of a panic attack.
So, if anxiety has so many negative effects, why is it relatively common? Many scientists who study anxiety disorders believe that many of the symptoms of anxiety (e.g., being easily startled, worrying about having enough resources) helped humans survive under harsh and dangerous conditions. For instance, being afraid of a snake and having a "fight or flight" response is most likely a good idea! It can keep you from being injured or even killed. When humans lived in hunter-gatherer societies and couldn't pick up their next meal at a grocery store or drive-through, it was useful to worry about where the next meal, or food for the winter, would come from. Similarly avoiding an area because you know there might be a bear would keep you alive —worry can serve to motivate behaviors that help you survive. But in modern society, these anxiety-related responses often occur in response to events or concerns that are not linked to survival. For example, seeing a bear in the zoo does not put you at any physical risk, and how well-liked you are at work does not impact your health or safety. In short, most experts believe that anxiety works by taking responses that are appropriate when there are real risks to your physical wellbeing (e.g., a predator or a gun), and then activating those responses when there is no imminent physical risk (e.g., when you are safe at home or work).
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.
