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.
Panic attacks, on the other hand, are short bursts of intense fear often marked by increased heart rate, brief chest pain or shortness of breath. Typically lasting fewer than 30 minutes, they could occur once or repeatedly — sometimes without reason. These episodes can send patients to the emergency room, as they are sometimes mistaken for a heart attack.
Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety. Anxiety disorders are the most common of mental disorders and affect more than 25 million Americans. But anxiety disorders are treatable and a number of effective treatments are available. Treatment helps most people lead normal productive lives.
What happens, exactly? "We all physically respond to stress," says Barbara O. Rothbaum, PhD, psychiatry professor and director, Trauma and Anxiety Recovery Program, at Atlanta's Emory University School of Medicine. "You might feel anxious about work-related problems, taking a big exam, or making an important decision. But someone who suffers from panic disorder may react to those same moderate pressures with an exaggerated physical reaction-as if he or she were about to be attacked by a wild tiger or fall from a great height. It's full-on, adrenaline-pumping, fight-or-flight response."
Secondly, the psychobiological conceptualization of panic disorder emphasizes the influence of psychological factors (Meuret, White, Ritz, Roth, Hofmann, & Brown, 2006). This psychological factor refers to a fear of bodily sensations, or a certain set of beliefs that lead individuals to be especially afraid of physical symptoms, such as believing that a racing heart could mean heart disease. Sometimes this is discussed as anxiety sensitivity or a belief that anxiety is harmful. Again, having the belief that physical symptoms are harmful may increase the likelihood of experiencing a panic attack, but it does not make having a panic attack inevitable. Instead, panic attacks can seem abnormal if they occur at the wrong time, when there is no real reason to be afraid. It is important to consider, however, that anxiety can also be adaptive or helpful in contexts where there is true threat.
Research upon adolescents who as infants had been highly apprehensive, vigilant, and fearful finds that their nucleus accumbens is more sensitive than that in other people when deciding to make an action that determined whether they received a reward. This suggests a link between circuits responsible for fear and also reward in anxious people. As researchers note, "a sense of 'responsibility', or self-agency, in a context of uncertainty (probabilistic outcomes) drives the neural system underlying appetitive motivation (i.e., nucleus accumbens) more strongly in temperamentally inhibited than noninhibited adolescents".
If you’ve been experiencing panic attacks or think you may have panic disorder, we encourage you to seek diagnosis and treatment from your doctor and a mental health professional. Although panic attacks can feel like a debilitating and embarrassing condition, it is important to remember that you aren’t alone and your mental health is nothing to be embarrassed about. There are a variety of resources available to you for advice and support, both online and in the form of support groups. For more information, ask your healthcare provider about what is available in your area and check out the links below:
A person with separation anxiety disorder is excessively fearful or anxious about separation from those with whom he or she is attached. The feeling is beyond what is appropriate for the person’s age, persists (at least four weeks in children and six months in adults) and causes problems functioning. A person with separation anxiety disorder may be persistently worried about losing the person closest to him or her, may be reluctant or refuse to go out or sleep away from home or without that person, or may experience nightmares about separation. Physical symptoms of distress often develop in childhood, but symptoms can carry though adulthood.
Anxiety disorders are associated with chronic life stress. Unpredictable, unrelenting, unresolvable stressors chronically stimulate the stress hormone system and cardiovascular system, and lead to states of constant increased activity. Biologically, the body has evolved to deal with imminent and concrete danger in the environment, rather than continuous stressors. Under normal conditions where chronic stress is low, exposure to a sudden threat activates the autonomic nervous system, i.e. increased levels of adrenaline and faster breathing, and racing heart rate. These reactions in turn trigger activation of stress hormones, such as cortisol. One of the effects of these stress hormones is to increase glucose levels in the bloodstream in order to respond to the imminent threat, so that muscles can be activated for the flight or fight response. Another effect of stress hormones is to supress the immune system, since processes such as healing and repair can wait until after the threat subsides. However, in someone with an anxiety disorder, where there is constant activation of these responses to everyday stressors, the stress hormone system loses its ability to control immune function, thus contributing to heightened systemic inflammation that increases risk for cardiovascular and even autoimmune disorders. Neuroscience and clinical research continues to investigate how anxiety disorders increase individual risk for developing physical health co-morbidities in hopes of identifying new treatments that may alleviate suffering from and prevent the development of these whole-body disorders.
Panic disorder is characterized by uncontrollable, recurrent episodes of panic and fear that peak within minutes. Panic attacks are accompanied by physical manifestations, such as heart palpitations, sweating, and dizziness as well as the fear of dying or becoming insane. Worry about having an attack may lead to additional anxiety and avoidance behaviors or to other problems in functioning.
Beta Blockers, also known as beta-adrenergic blocking agents, work by blocking the neurotransmitter epinephrine (adrenaline). Blocking adrenaline slows down and reduces the force of heart muscle contraction resulting in decreased blood pressure. Beta blockers also increase the diameter of blood vessels resulting in increased blood flow. Historically, beta blockers have been prescribed to treat the somatic symptoms of anxiety (heart rate and tremors) but they are not very effective at treating the generalized anxiety, panic attacks or phobias. Lopressor and Inderal are some of the brand names with which you might be familiar.
Fortunately, panic disorder is a treatable condition. Psychotherapy and medications have both been used, either singly or in combination, for successful treatment of panic disorder. If medication is necessary, your doctor may prescribe anti-anxiety medications, certain antidepressants or sometimes certain anticonvulsant drugs that also have anti-anxiety properties, or a class of heart medications known as beta-blockers to help prevent or control the episodes in panic disorder.
Specialized coils that targetes deeper brain regions than rTMS. A patient wears a cushioned helmet (similar to the type of helmet worn during an fMRI). The coil used in dTMS was approved by the FDA in 2013 for treating depression but is currently being studied for the treatment of anxiety disorders such as OCD. The procedue is administered for 20 minutes for 4-6 weeks. Patients can resume their daily lives right after each treatment.
A panic attack begins suddenly and unexpectedly and most often peaks within 10 to 20 minutes. At times, the resulting anxiety may last a couple of hours. Panic attacks can occur whether the person is calm or anxious. Recalling a past attack may trigger a new one. The frequency of panic attacks can vary, and for some people the fear of having an additional attack may lead them to avoid situations where escape may be difficult, such as being in a crowd or traveling in a car or bus.
Cognitive Behavioral Therapy (CBT) is an example of one type of psychotherapy that can help people with anxiety disorders. It teaches people different ways of thinking, behaving, and reacting to anxiety-producing and fearful objects and situations. CBT can also help people learn and practice social skills, which is vital for treating social anxiety disorder.
