Most people have experienced fleeting symptoms associated with anxiety disorders at some point in their life. Such feelings — such as having a shortness of breath, feeling your heart pounding for no apparent reason, experiencing dizziness or tunnel vision — usually pass as quickly as they come and don’t readily return. But when they do return time and time again, that can be a sign that the fleeting feelings of anxiety have turned into an anxiety disorder.
An anxiety attack can be described as a sudden attack of fear, terror, or feelings of impending doom that strike without warning and for no apparent reason. This strong sensation or feeling can also be accompanied by a number of other symptoms, including pounding heart, rapid heart rate, sweating, lightheadedness, nausea, hot or cold flashes, chest pain, hands and feet may feel numb, tingly skin sensations, burning skin sensations, irrational thoughts, fear of losing control, and a number of other symptoms. (While other symptoms often do accompany anxiety attacks, they don’t necessarily have to.)
Characterized by a preoccupation with the belief that one's body or appearance are unattractive, ugly, abnormal or deformed. This preoccupation can be directed towards one or many physical attributes (e.g., acne, hair loss, facial features). Muscle dysmorphia is a subtype of this disorder that is characterized by belief that one's body is too small or insufficiently muscular.
These attacks are a symptom of panic disorder, a type of anxiety disorder that affects some 2.4 million U.S. adults. The disorder most often begins during the late teens and early adulthood and strikes twice as many American women as men. No one knows what causes panic disorder, though researchers suspect a combination of biological and environmental factors, including family history (panic disorder seems to run in families), stressful life events, drug and alcohol abuse, and thinking patterns that exaggerate normal physical reactions.
Paula had her first panic attack six months ago. She was in her office preparing for an important work presentation when, suddenly, she felt an intense wave of fear. Then the room started spinning and she felt like she was going to throw up. Her whole body was shaking, she couldn’t catch her breath, and her heart was pounding out of her chest. She gripped her desk until the episode passed, but it left her deeply shaken.
The symptoms of a panic attack may cause the person to feel that their body is failing. The symptoms can be understood as follows. First, there is frequently the sudden onset of fear with little provoking stimulus. This leads to a release of adrenaline (epinephrine) which brings about the fight-or-flight response when the body prepares for strenuous physical activity. This leads to an increased heart rate (tachycardia), rapid breathing (hyperventilation) which may be perceived as shortness of breath (dyspnea), and sweating. Because strenuous activity rarely ensues, the hyperventilation leads to a drop in carbon dioxide levels in the lungs and then in the blood. This leads to shifts in blood pH (respiratory alkalosis or hypocapnia), causing compensatory metabolic acidosis activating chemosensing mechanisms which translate this pH shift into autonomic and respiratory responses. The person him/herself may overlook the hyperventilation, having become preoccupied with the associated somatic symptoms.
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.
