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.
Obsessive-compulsive Disorder (OCD): In OCD, a person becomes trapped in a pattern of repetitive thoughts and behaviors that are senseless and distressing but extremely difficult to overcome. Such rituals as counting, prolonged handwashing, and repeatedly checking for danger may occupy much of the person’s time and interfere with other activities. Like panic disorder, OCD can be treated effectively with medication and/or psychotherapy.
The cause of anxiety disorders is a combination of genetic and environmental factors. Anxiety can stem itself from certain factors: genetics, medicinal side-effects, shortness of oxygen. Risk factors include a history of child abuse, family history of mental disorders, and poverty. Anxiety disorders often occur with other mental disorders, particularly major depressive disorder, personality disorder, and substance use disorder. To be diagnosed symptoms typically need to be present at least six months, be more than would be expected for the situation, and decrease functioning. Other problems that may result in similar symptoms including hyperthyroidism, heart disease, caffeine, alcohol, or cannabis use, and withdrawal from certain drugs, among others.
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.
People generally can overcome panic attacks faster if they seek help after the first one or two, says psychologist Cheryl Carmin, PhD, director of clinical psychology training at the Wexner Medical Center and a professor at Ohio State University in Columbus. When you do seek help, your doctor or therapist will ask about your symptoms and the situations in which they arise, and might also recommend additional medical testing to rule out other health concerns.
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.
There are many highly effective treatment options available for anxiety and anxiety-related disorders. These treatments can be broadly categorized as: 1) Psychotherapy; 2) Medications; and 3) Complementary and Alternative Therapies. Patients diagnosed with anxiety can benefit from one or a combination of these various therapies. Discussions of emerging therapies and types of care providers are also included.
Agoraphobia: This is a fear and avoidance of places, events, or situations from which it may be difficult to escape or in which help would not be available if a person becomes trapped. People often misunderstand this condition as a phobia of open spaces and the outdoors, but it is not so simple. A person with agoraphobia may have a fear of leaving home or using elevators and public transport.
A number of medical conditions can cause anxiety symptoms. These include an overactive thyroid, hypoglycemia, mitral valve prolapse, anemia, asthma, COPD, inflammatory bowel disease, Parkinson's disease, and dementia among others. Your physician may perform certain tests to rule out these conditions. But it is important to remember that anxiety is more often due to poor coping skills or substance abuse than any medical condition.
Warren: So if you’re walking down a dark alley, you are probably thinking that there could be potential danger; that anxiety of anticipation, the feeling in your stomach, the elevated heart rate. But if you’re walking down that alley and somebody jumps out with a knife, then you’re likely to have a panic attack — an overwhelming urge to escape a situation that is dangerous.
Although individual participants may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future. Decisions about whether to apply for a clinical trial and which ones are best suited for a given individual are best made in collaboration with a licensed health professional.
