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.
Great questions. Unfortunately, there is usually no clear cut answer – and like many mental health disorders – it is likely caused by a combination of genetic, behavioral, and developmental factors. Anatomically speaking, Generalized Anxiety Disorder is most closely related to a disruption in the functional connectivity of the amygdala – the “emotional control center” of the brain – and how it processes feelings of fear and anxiety. Genetics also play a role in Generalized Anxiety Disorder. If you have a family member that also suffers from this disorder, your chances of suffering from it are increased, especially in the presence of a life stressor. Interestingly, long-term substance abuse also increases your chances of Generalized Anxiety Disorder, as the use of benzodiazepines can worsen your anxiety levels, as can excessive alcohol use. Tobacco use and caffeine are also both associated with increased levels of anxiety.
Social Anxiety Disorder;Fear of social situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be embarrassing and humiliating, often times leading to avoidance of social situations and severe distress when participation in social situations can't be avoided. 
Panic disorder is thought to have a psychobiological conceptualization (Craske & Barlow, 2007). This does not mean that panic attacks are due to a biological disease. What this does mean is that there are certain biological factors that may be inherited or passed on through genes, and thus may lead some people to be more likely than others to experience panic disorder symptoms. This is likely why panic disorder seems to run in families. In other words, if one family member has panic disorder, the other family members are more likely to experience panic symptoms or panic disorder compared to people without a family history of panic disorder. It is very important to note that just inheriting these vulnerabilities to panic does not make the onset of panic attacks inevitable or unalterable. In fact, it is possible to think and act in ways that prevent panic attacks.
When we’re anxious, the body produces a stress response. The stress response is designed to give us an extra ‘boost’ of awareness and energy when we think we could be in danger. The stress response causes a number of physiological, psychological, and emotional changes in the body that enhance the body’s ability to deal with a perceived threat – to either fight or flee, which is the reason the stress response is often referred to as the ‘fight or flight response.’
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.

Palpitations are uncomfortable sensations of the heart beating hard, rapidly, or irregularly. Some types of palpitations are benign, while others are more serious. Palpitations are diagnosed by taking the patient history and by performing an EKG or heart monitoring along with blood tests. An electrophysiology study may also be performed. Treatment of palpitations may include lifestyle changes, medication, ablation, or implantation of a pacemaker. The prognosis if palpitations depends on the underlying cause.
