Researchers have conducted both animal and human studies to pinpoint the particular parts of the brain that are involved in anxiety and fear. Because fear evolved to deal with danger, it sets off an immediate protective response without conscious thought. This fear response is believed to be coordinated by the amygdala, a structure deep inside the brain. Although relatively small, the amygdala is quite complex, and recent studies suggest that anxiety disorders may be associated with abnormal activity within it.
This disorder is characterized by panic attacks and sudden feelings of terror sometimes striking repeatedly and without warning. Often mistaken for a heart attack, a panic attack causes powerful physical symptoms including chest pain, heart palpitations, dizziness, shortness of breath and stomach upset. Many people will go to desperate measures to avoid an attack, including social isolation.
Mitral valve prolapse (MVP), also called "click murmur syndrome" and "Barlow's syndrome," is the most common type of heart valve abnormality. Usually, people with mitral valve prolapse have no signs and symptoms; however, if the prolapsed valve is severe, symptoms may appear. When symptoms of severe mitral valve prolapse do appear, they may include, fatigue, palpitations, chest pain, anxiety, migraine headaches, and pulmonary edema. Echocardiography is the most useful test for mitral valve prolapse. Most people with mitral valve need no treatment. However, if the valve prolapse is severe, treatment medications or surgery may be necessary to repair the heart valve.
Had my first panic attack today and wanted to be sure about what I was experiencing. I sat there crying hysterically, hyperventilating, chest shaking, my hands went very numb. Took me about 10 minutes to get sort of calm, sat in the shower for about half an hour afterwards to fully calm myself down. Every time I tried to focus on my breathing and taking longer breaths I would start hyperventilating again. Felt like I was choking, awful awful experience.
If you are greatly afraid, however, such as being terrified that there is a burglar in your home that is about to harm you, the body produces a high degree stress response. We generally experience high degree stress responses as being anxiety attacks: where the changes are so profound they get our full attention. The greater the degree of anxiety and stress response, the more changes the body experiences.
In people with anxiety disorders, the brain circuitry that controls the threat response goes awry. At the heart of the circuit is the amygdala, a structure that flags incoming signals as worrisome and communicates with other parts of the brain to put the body on alert for danger. Early life events, especially traumatic ones, can program the circuitry so that it is oversensitive and sends out alarms too frequently and with only minor provocations. Survival mandates a system for perceiving threats and taking quick, automatic action, but those with anxiety see threats where there are none, perhaps because emotional memories color their perceptions.
Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external stimuli will trigger its onset or exacerbation. Genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder. Although single genes are neither necessary nor sufficient for anxiety by themselves, several gene polymorphisms have been found to correlate with anxiety: PLXNA2, SERT, CRH, COMT and BDNF. Several of these genes influence neurotransmitters (such as serotonin and norepinephrine) and hormones (such as cortisol) which are implicated in anxiety. The epigenetic signature of at least one of these genes BDNF has also been associated with anxiety and specific patterns of neural activity.
Panic attacks are extremely unpleasant and can be very frightening. As a result, people who experience repeated panic attacks often become very worried about having another attack and may make changes to their lifestyle so as to avoid having panic attacks. For example, avoiding exercise so as to keep their heart rate low, or avoiding certain places.
Panic attacks are common among all anxiety disorders but what sets panic disorder apart is that panic attacks are unexpected and occur "out of the blue" without an obvious trigger (American Psychiatric Association, 2013; Craske & Barlow, 2007). These unexpected panic attacks must be associated with a significant change in behavior or be followed by at least one month of persistent worry about having another attack or about what will happen if you have another panic attack.
I experienced my first panic attack this year around February! I was at work, checking people bags and etc.. then all of a sudden a big strong rush hit my whole entire body ! So I walked over to my desk to relax and calm down for about 15 mins, I was so scared my hands and feet were tingling , my head was spinning, too many people was around me I was getting irritated! My heart was beating so fast! My body wouldn’t stop shaking! My hands was getting clams! I didn’t know what to do! Ever since my girlfriend moved to another city , I didn’t have no one anymore , so I had car problems and kept losing jobs !!! So then I been stressing about everything thinking she’s gonna leave me and I won’t be able to see her again, or I won’t ever get a car or have a stable job! But once I figured out it was a panic attack I calmed down! I seriously thought something was wrong with me. It felt like I was about to pass out on the floor or something ! This is something I would never thought I would experienced !! So now on everyday to day basis, I have anxiety from time to time ! But I’m trying not to make medication for it because I do not want to take any pills to calm me down or put me to sleep! If I can do before without pills than I can do it again. Some days I couldn’t control it but I always say “ hey it’s okay, just relax your tripping ain’t nothing wrong”. Some days I have headaches that come and go but people tell me it’s anxiety and I’m like do anxiety really give me headaches? Because my head feels like it’s so tight , then I have pain in my neck. So by me getting irritated by the headache and neck pain I get to thinking something wrong but I know it’s stress. But since I got a stable job, and a car and a roof over my head now I feel a little better but I still have anxiety attacks from time to time. Hopefully it will go away soon. But until then ima fight it like I never had and ima try to ignore it by meditating and listening to music !! I also made a Facebook page for people who going through the same thing as me !
It is not unusual to experience only one or two symptoms at a time, such as vibrations in their legs, shortness of breath, or an intense wave of heat traveling up their bodies, which is not similar to hot flashes due to estrogen shortage. Some symptoms, such as vibrations in the legs, are sufficiently different from any normal sensation that they clearly indicate panic disorder. Other symptoms on the list can occur in people who may or may not have panic disorder. Panic disorder does not require four or more symptoms to all be present at the same time. Causeless panic and racing heartbeat are sufficient to indicate a panic attack.
Paula had her next panic attack three weeks later, and since then, they’ve been occurring with increasing frequency. She never knows when or where she’ll suffer an attack, but she’s afraid of having one in public. Consequently, she’s been staying home after work, rather than going out with friends. She also refuses to ride the elevator up to her 12th floor office out of fear of being trapped if she has a panic attack.
2) If you suddenly feel your heart pounding or experience other physical clues that a panic attack is barreling for you, try this distraction suggested by Rob Cole, LHMC, clinical director of mental health services at Banyan Treatment Centers. Start counting backward from 100 by 3s. The act of counting at random intervals helps you to focus and override the anxious thoughts that are trying to sneak into your psyche. Better still keep loose change in your pocket. Add a dime to a nickel, then add two pennies and so on. By controlling your thoughts and focusing on something outside yourself you will being to feel calmer.
Exercise regularly. Exercise is a natural stress buster and anxiety reliever. To achieve the maximum benefit, aim for at least 30 minutes of aerobic exercise on most days (broken up into short periods if that’s easier). Rhythmic activities that require moving both your arms and legs are especially effective. Try walking, running, swimming, martial arts, or dancing.
Exposure therapy for panic disorder with agoraphobia includes exposure to the situations you fear and avoid is also included in treatment. As in exposure therapy for specific phobias, you face the feared situation until the panic begins to go away. Through this experience, you learn that the situation isn’t harmful and that you have control over your emotions.
Nevertheless, if you are struggling with symptoms of an anxiety disorder it is not uncommon to feel alone and misunderstood. Because the fear that people with an anxiety disorder have is not experienced by others, they may not understand why, for example, being in a crowd of people, not being able to wash your hands after meeting a new person, or driving through the street where you got in a car accident can be really anxiety-provoking for someone with an anxiety disorder. People may comment that "there is no reason to worry about it" or that you "should just let it go".
Medication does not cure anxiety disorders but can help relieve symptoms. Medication for anxiety is prescribed by doctors, such as a psychiatrist or primary care provider. Some states also allow psychologists who have received specialized training to prescribe psychiatric medications. The most common classes of medications used to combat anxiety disorders are anti-anxiety drugs (such as benzodiazepines), antidepressants, and beta-blockers.
