Test anxiety is the uneasiness, apprehension, or nervousness felt by students who have a fear of failing an exam. Students who have test anxiety may experience any of the following: the association of grades with personal worth; fear of embarrassment by a teacher; fear of alienation from parents or friends; time pressures; or feeling a loss of control. Sweating, dizziness, headaches, racing heartbeats, nausea, fidgeting, uncontrollable crying or laughing and drumming on a desk are all common. Because test anxiety hinges on fear of negative evaluation, debate exists as to whether test anxiety is itself a unique anxiety disorder or whether it is a specific type of social phobia. The DSM-IV classifies test anxiety as a type of social phobia.
Furthermore, certain organic diseases may present with anxiety or symptoms that mimic anxiety. These disorders include certain endocrine diseases (hypo- and hyperthyroidism, hyperprolactinemia), metabolic disorders (diabetes), deficiency states (low levels of vitamin D, B2, B12, folic acid), gastrointestinal diseases (celiac disease, non-celiac gluten sensitivity, inflammatory bowel disease), heart diseases, blood diseases (anemia), cerebral vascular accidents (transient ischemic attack, stroke), and brain degenerative diseases (Parkinson's disease, dementia, multiple sclerosis, Huntington's disease), among others.
Heredity, other biological factors, stressful life events, and thinking in a way that exaggerates relatively normal bodily reactions are all believed to play a role in the onset of panic disorder. Some research suggests panic attacks occur when a “suffocation alarm mechanism” in the brain is activated, falsely reporting that death is imminent. The exact cause or causes of panic disorder are unknown and are the subject of intense scientific investigation.
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. 
Anxiety attacks usually peak within 10 minutes, and they rarely last more than 30 minutes. But during that short time, the terror can be so severe that you feel as if you’re about to die or totally lose control. The physical symptoms of anxiety attacks are themselves so frightening that many people believe they’re having a heart attack. After an anxiety attack is over, you may be worried about having another one, particularly in a public place where help isn’t available or you can’t easily escape.
Research is inconsistent as to whether nutritional deficiencies (for example, zinc or magnesium deficiency) may be risk factors for panic disorder. While food additives like aspartame, alone or in combination with food dyes, are suspected to play a role in the development of panic attacks in some people, it has not been confirmed by research so far.
ACT is a type of CBT that encourages patients to again in positive behaviors even in the presence of negative thoughts and behaviors. The goal is to improve daily functioning despire having the disorder. It is particularly useful for treatment-resistant Generalized Anxiety Disorder and Depression. The length of treatment varies depending on the severity of symptoms.
CBT is a short-term treatment designed to help patients identify inaccurate and negative thinking in situations that cause anxiety like panic attacks. CBT can be used in one-on-one therapy or in a group therapy session with people facing similar problems. CBT primarily focuses on the ongoing problems in a patient's life and helps them develop new ways of processing their feelings, thoughts and behaviors to develop more effective ways of coping with their life. In patients who suffer from PTSD, CBT can take on a trauma-focused approach, where the goal is to process and reframe the traumatic experience that lead to the symptoms. On average, the length of treatment is around 10-15 weekly one-hour sessions depending on the type and severity of symptoms.
Additionally, there is some evidence that Acceptance and Commitment Therapy (ACT), Mindfulness-based Stress Reduction treatment (MBSR), as well as online and computerized treatments are effective in treating panic disorder (Arch et al., 2017). However, the overwhelming majority of research supports the long-term success of CBT for treating panic disorder. More research is needed to explore the extent to which MBSR and ACT work when compared to CBT and other treatments, but preliminary results are positive. In general, empirically-supported treatments that are founded on the basis of research within the psychological and medical fields are recommended for treating panic disorder.
Learn how to control your breathing. Hyperventilation brings on many sensations (such as lightheadedness and tightness of the chest) that occur during a panic attack. Deep breathing, on the other hand, can relieve the symptoms of panic. By learning to control your breathing, you can calm yourself down when you begin to feel anxious. And if you know how to control your breathing, you’re also less likely to create the very sensations that you’re afraid of.
Cognitive distortions such as overgeneralizing, catastrophizing, mind reading, emotional reasoning, binocular trick, and mental filter can result in anxiety. For example, an overgeneralized belief that something bad "always" happens may lead someone to have excessive fears of even minimally risky situations and to avoid benign social situations due to anticipatory anxiety of embarrassment. In addition, those who have high anxiety can also create future stressful life events. Together, these findings suggest that anxious thoughts can lead to anticipatory anxiety as well stressful events, which in turn cause more anxiety. Such unhealthy thoughts can be targets for successful treatment with cognitive therapy.
Anxiety cannot increase forever and you cannot experience peak levels of anxiety forever. Physiologically there is a point at which our anxiety cannot become any higher and our bodies will not maintain that peak level of anxiety indefinitely. At that point, there is nowhere for anxiety to go but down. It is uncomfortable to reach that peak but it is important to remember this anxiety will even out and then go down with time.
After a number of panic episodes, the individual can become afraid of being a helpless victim of panic. He or she may hesitate to be alone, to venture far from home, or to be in public places. Even when not experiencing an anxiety attack, the person with panic attacks often becomes increasingly nervous and apprehensive. He or she attempts to remain physically and psychologically tense in preparation for the next attack.
Seeing a friend or loved one suffering a panic attack can be frightening. Their breathing may become abnormally fast and shallow, they could become dizzy or light-headed, tremble, sweat, feel nauseous, or think they’re having a heart attack. No matter how irrational you think their panicked response to a situation is, it’s important to remember that the danger seems very real to your loved one. Simply telling them to calm down or minimizing their fear won’t help. But by helping your loved one ride out a panic attack, you can help them feel less fearful of any future attacks.
Panic attacks and panic disorder are treatable once the underlying cause of is identified. “Usually medical conditions and other factors (substance use or withdrawal from substances) are ruled out before making the diagnosis,” says Flo Leighton, psychiatric nurse practitioner, and therapist with Union Square Practice in Manhattan. Getting to the root cause typically takes a couple of sessions, says Leighton. Here are some options that may be recommended to you :
The emotional effects of anxiety may include "feelings of apprehension or dread, trouble concentrating, feeling tense or jumpy, anticipating the worst, irritability, restlessness, watching (and waiting) for signs (and occurrences) of danger, and, feeling like your mind's gone blank" as well as "nightmares/bad dreams, obsessions about sensations, déjà vu, a trapped-in-your-mind feeling, and feeling like everything is scary."
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.)
