But over time, you may find yourself experiencing more panic attacks, in a variety of circumstances. Most of these will not be entirely unexpected. Most subsequent attacks occur in response to various cues such as entering a crowded area; a traffic jam; or simply worrying about having a panic attack. But there may still be some surprises: for instance, you might have a nocturnal panic attack, which wakes you out of a sound sleep. Or you might find yourself experiencing odd feelings of depersonalization as you kill some time with friends or colleagues.
In the central nervous system (CNS), the major mediators of the symptoms of anxiety disorders appear to be norepinephrine, serotonin, dopamine, and gamma-aminobutyric acid (GABA). Other neurotransmitters and peptides, such as corticotropin-releasing factor, may be involved. Peripherally, the autonomic nervous system, especially the sympathetic nervous system, mediates many of the symptoms. Increased flow in the right parahippocampal region and reduced serotonin type 1A receptor binding in the anterior and posterior cingulate and raphe of patients are the diagnostic factors for prevalence of anxiety disorder.
While a single panic attack may only last a few minutes, the effects of the experience can leave a lasting imprint. If you have panic disorder, the recurrent panic attacks take an emotional toll. The memory of the intense fear and terror that you felt during the attacks can negatively impact your self-confidence and cause serious disruption to your everyday life. Eventually, this leads to the following panic disorder symptoms:
“Panic disorder is diagnosed if the individual has recurrent panic attacks (minimum four in a four-week period), and at least one of the attacks is accompanied by one or more physical symptoms, including persistent concern about having another attack, worry about the implication or consequences of the attack (i.e., having a heart attack), and/or a significant change in behaviour due to the attacks, such as quitting a job.7 In addition, the panic attacks cannot be due to the physiological effects of a substance or another general medical condition.”[1]

Agoraphobia is often comorbid with panic disorder — meaning people often suffer from both conditions at the same time. It's an intense fear of not being able to escape whatever place you're in, and can often lead to an avoidance of leaving the house. People with agoraphobia can fear situations where this anxiety might flare up, and typically don't feel comfortable or safe in public, crowded places. 
There are two very important guidelines to think about, aside from symptoms. These are duration of symptoms and level of impairment. Anxiety is a normal reaction to stressful situations, and even high levels of anxiety can be healthy and beneficial at times. Disorders are only present when anxiety symptoms last for several weeks to months and significantly interfere with every day function or cause long-lasting distress.
I had the biggest panic attack to date today, managed to get into the car with my friends to take my son for a hospital appointment, felt very unsafe and thought I was going to fall out of the car when it went around a corner. Talked to myself all through the journey telling myself I’d been round hundreds of corners and never fallen out out a car yet…got the hospital, got out the car, got half way across the carpark and had what I can only describe as the most hysterical panic/anxiety attack I have ever had. I,d dropped to the floor by now as I was with my friend Kay and I knew she wouldnt be able to run after me….I was screaming, pleading for help for what felt like forever, 2 paramedics came over and it took them a good 10 minutes to convince me I should stand up and go into A&E, I can only explain the whole thing as being hysterical, a Crisis nurse and doctor came to see my and gave me 4 diazepam, even after taking one – 5mg – I was hysterical and wouldnt then leave the hospital…I,m now at home and a lot calmer, the Crisis team are coming to see me between 10am and 1pm tomorrow to discuss meds, even the nurse said to the doctor ‘this isnt depression, this is severe anxiety..’ all I need is a tiny pinprick of light to look at to keep me hopeful. I honestly thought I could handle today but I didnt, I,m angry and disappointed with myself as this time a month ago I was fine
Panic disorder is a separate but related diagnosis to panic attacks. People experiencing repeated panic attacks and who meet other diagnostic criteria may be diagnosed with this illness. Panic disorder is thought to have more of an inherited component than panic attacks that are not a part of panic disorder. Certain medical conditions, like asthma and heart disease, as well as certain medications, like steroids and some asthma medications, can cause anxiety attacks as a symptom or side effect. As individuals with panic disorder are at higher risk of having a heart-valve abnormality called mitral valve prolapse (MVP), that should be evaluated by a doctor since MVP may indicate that specific precautions be taken when the person is treated for a dental problem.
Anxiety disorders are characterized by a general feature of excessive fear (i.e. emotional response to perceived or real threat) and/or anxiety (i.e. worrying about a future threat) and can have negative behavioral and emotional consequences. Obsessive-compulsive and related disorders are characterized by obsessive, intrusive thoughts (e.g., constantly worrying about staying clean, or about one's body size) that trigger related, compulsive behaviors (e.g. repeated hand-washing, or excessive exercise). These behaviors are performed to alleviate the anxiety associated with the obsessive thoughts. Trauma- and stressor- related anxiety disorders are related to the experience of a trauma (e.g., unexpected death of a loved one, a car accident, or a violent incident) or stressor (e.g., divorce, beginning college, moving).
Fortunately, panic disorder is one of the most treatable of the anxiety disorders. Psychotherapy (sometimes called talk therapy), cognitive, or biofeedback therapy can all help alter a person's response to stimuli. Medications, such as antidepressants and beta-blockers, are another option. And certain lifestyle changes, such as limiting caffeine and sticking to a daily exercise plan, can decrease symptoms as well.

Anxiety disorders are the most commonly diagnosed mental disorders in the United States. The most common type of anxiety disorder are called “simple phobias,” which includes phobias of things like snakes or being in a high place. Up to 9 percent of the population could be diagnosed with this disorder in any given year. Also common are social anxiety disorder (social phobia, about 7 percent) — being fearful and avoiding social situations — and generalized anxiety disorder (about 3 percent).

According to the American Psychological Association, "most specialists agree that a combination of cognitive and behavioral therapies are the best treatment for panic disorder. Medication might also be appropriate in some cases."[50] The first part of therapy is largely informational; many people are greatly helped by simply understanding exactly what panic disorder is and how many others suffer from it. Many people who suffer from panic disorder are worried that their panic attacks mean they are "going crazy" or that the panic might induce a heart attack. Cognitive restructuring helps people replace those thoughts with more realistic, positive ways of viewing the attacks.[51] Avoidance behavior is one of the key aspects that prevent people with frequent panic attacks from functioning healthily.[14] Exposure therapy,[52] which includes repeated and prolonged confrontation with feared situations and body sensations, helps weaken anxiety responses to these external and internal stimuli and reinforce realistic ways of viewing panic symptoms.
A first panic attack is usually unexpected, and comes "out of the blue." It may scare you so much that you start taking steps to protect yourself from future attacks. Maybe you start avoiding places that remind you of your first attack. Maybe you only go out after making sure you have your cell phone, a bottle of water, and other objects you hope will keep you safe. Maybe you try hard to "stop thinking about it." You work hard to keep the panic at bay.
Anyone who’s ever had a panic attack can tell you what a rollercoaster-of-a-ride it can be. It comes on suddenly, gripping its victims in extreme fear and heart-thumping, breathtaking physical distress. Minutes later, it’s over. When panic attacks occur repeatedly and people’s lives are gripped by fear of having the next panic episode, they may be diagnosed with panic disorder.
I don’t know if I’m having anxiety attacks but every time I face a minor problem in my life, even if it us really stupid, I feel like I want to cry, to scream, and it’s like something is blocking my throat. I can’t control my anger during those moments, so I usually turn off my phone so I don’t say things I don’t mean to my friends or my family when I’m panicking and overthinking about any minor situation.

When people are confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes, PET-scans show increased bloodflow in the amygdala.[87][88] In these studies, the participants also reported moderate anxiety. This might indicate that anxiety is a protective mechanism designed to prevent the organism from engaging in potentially harmful behaviors.

As is the case the more generalized forms of social anxiety, intergroup anxiety has behavioral, cognitive, and affective effects. For instance, increases in schematic processing and simplified information processing can occur when anxiety is high. Indeed, such is consistent with related work on attentional bias in implicit memory.[35][36][37] Additionally recent research has found that implicit racial evaluations (i.e. automatic prejudiced attitudes) can be amplified during intergroup interaction.[38] Negative experiences have been illustrated in producing not only negative expectations, but also avoidant, or antagonistic, behavior such as hostility.[39] Furthermore, when compared to anxiety levels and cognitive effort (e.g., impression management and self-presentation) in intragroup contexts, levels and depletion of resources may be exacerbated in the intergroup situation.

From a cardiac standpoint, unless coincident heart disease is also present, the prognosis after having chest pain due to an anxiety attack is very good. However, all too often—especially in an emergency room setting where people who have chest pain due to anxiety attacks often wind up—doctors who rule out a cardiac emergency are likely to brush the patient off as having a minor problem of no significance; but panic attacks should not be brushed off.
Here’s another way to differentiate those feelings. Let’s say you’re someone who suffers from panic attacks. If you’re worried about having the next panic attack, that’s “anticipatory anxiety—the worry of, Oh, no, I’m going to have a panic attack,” says Brown. On the other hand, “The emotion I’m feeling when I’m having a panic attack we would think of as fear.”
Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:

No matter what your plan is, having one in place is the most important thing. You can think of your plan as your go-to set of instructions for yourself when you feel a panic attack coming on. One plan might be to take yourself out of your current environment, sit down, and call a friend or family member that can help distract you from your symptoms and help you to calm down. Then you can incorporate the following techniques.
Exposure therapy for panic disorder allows you to experience the physical sensations of panic in a safe and controlled environment, giving you the opportunity to learn healthier ways of coping. You may be asked to hyperventilate, shake your head from side to side, or hold your breath. These different exercises cause sensations similar to the symptoms of panic. With each exposure, you become less afraid of these internal bodily sensations and feel a greater sense of control over your panic.
Complementary and Alternative Therapies can be used in conjunction with conventional therapies to reduce the symptoms of anxiety. There is a growing interest in these types of alternative therapies, since they are non-invasive and can be useful to patients. They are typically not intended to replace conventional therapies but rather can be an adjunct therapy that can improve the overall quality of life of patients.
I think I suffered an anxiety/panic attack a few days ago. I was sitting down and something just came over me. My throat started to feel uncomfortable, like I couldn’t swallow. It scared me so I went outside to get fresh air. I was hoping that this feeling would go away in a few hours but it didn’t. I was very irritable and I would freak out if I got too hot. Later that night, I couldn’t sleep at all. My chest felt heavy and I was dreaming so I kept waking up. The feeling finally started to ease up about three days later. I’ve always dealt with anxiety but I’ve never experienced a panic attack and boy was it scary. I’m learning how to breathe and using Lavender Essential Oil to help me relax and stay calm.

Selective mutism: A somewhat rare disorder associated with anxiety is selective mutism. Selective mutism occurs when people fail to speak in specific social situations despite having normal language skills. Selective mutism usually occurs before the age of 5 and is often associated with extreme shyness, fear of social embarrassment, compulsive traits, withdrawal, clinging behavior, and temper tantrums. People diagnosed with selective mutism are often also diagnosed with other anxiety disorders.
