Flight experience with the use of anti-anxiety medications like benzodiazepines or other relaxant/depressant drugs varies from person to person. Medication decreases the person's reflective function. Though this may reduce anxiety caused by inner conflict, reduced reflective function can cause the anxious flier to believe what they are afraid will happen is actually happening.
A double-blind clinical study at the Stanford University School of Medicine suggests that anti-anxiety medication can keep a person from becoming accustomed to flight. In the research, two flights were conducted. In the first flight, though patients given alprazolam (Xanax) reported less anxiety than those receiving a placebo, their measurable stress increased. The heart rate in the alprazolam group was 114 versus 105 beats per minute in the placebo group. Those who received alprazolam also had increased respiration rates (22.7 vs 18.3 breaths/min).
On the second flight, no medication was given. Seventy-one percent of those who received alprazolam on the first flight experienced panic as compared with only 29% of those who received a placebo on the first flight. This suggests that the participants who were not medicated on the first flight benefited from the experience via some degree of desensitization.
Typical pharmacologic therapy is 0.5 or 1.0 mg of alprazolam about an hour before every flight, with an additional 0.5-1.0 mg if anxiety remains high during the flight. The alternative is to advise patients not to take medication, but encourage them to fly without it, instructing them in the principles of self-exposure.
Timed light exposure can be effective to help people match their circadian rhythms with the expected cycle at their destination; it requires strict adherence to timing. Light therapy is a popular method used by professional athletes to reduce jet lag. Special glasses, usually battery-driven, provide light to the eyes, thus inhibiting the production of melatonin in the brain. Timed correctly, the light may contribute to an advance or delay of the circadian phase to that which will be needed at the destination. The glasses may be used on the plane or even before users leave their departure city.
Timed melatonin administration may be effective in reducing jet lag symptoms. The benefit of using melatonin is likely to be greater for eastward flights than for westward ones because for most people it is easier to delay than to advance the circadian rhythm. There remain issues regarding the appropriate timing of melatonin use in addition to the legality of the substance in certain countries. How effective it may actually be is also questionable. For athletes, anti-doping agencies may prohibit or limit its use.
Timing of exercise and food consumption have also been suggested as remedies, though their applicability in humans and practicality for most travellers are not certain, and no firm guidelines exist. There are very little data supporting the use of diet to adjust to jet lag. While there are data supporting the use of exercise, the intensity of exercise that may be required is significant, and possibly difficult to maintain for non-athletes. These strategies may be used both before departure and after landing. Individuals may differ in their susceptibility to jet lag and in how quickly they can adjust to new sleep-wake schedules.
Short-acting sleep medications can be used to improve sleep quality and timing, and stimulating substances such as caffeine can be used to promote wakefulness, though research results on their success at adapting to jet lag are inconsistent.
For time changes of fewer than three hours, jet lag is unlikely to be a concern, and if travel is for short periods (three days or fewer) retaining a "home schedule" may be better for most people. Sleeping on the plane is only advised if it is within the destination's normal sleep time.
Training courses in public speaking and/or organizations such as Australian Rostrum, Toastmasters International, POWERtalk International, and Association of Speakers Clubs can help people to reduce their fear of public speaking to manageable levels. Self-help materials that address public speaking are among the best selling self-help topics. To temporarily treat their phobia, some affected people have turned to certain types of medications, typically beta blockers.
In some cases, anxiety can be mitigated by a speaker not attempting to resist their anxiety, thus fortifying the anxiety/fight-or-flight loop. Other strategies involve using one's nervousness to enliven an otherwise fearful speech presentation.
A speaker's anxiety can also be reduced if they know their topic well and believe in it. It has been suggested that people should practice speaking in front of smaller, less intimidating groups when they're getting started in public speaking. Additionally, focusing on friendly, attentive people in the audience has been found to help.
Traditional advice has been to urge fearful speakers not to take themselves too seriously, and to be reminded that mistakes are often unnoticed by audiences. Gaining experience in public speaking often results in it becoming less anxiety-provoking over time. Recent studies suggest that there is a close link between fear of public speaking and self-efficacy and that attempts to help presenters improve their self-efficacy will also reduce this fear.
Loosening up a "tough crowd" by asking questions promotes audience participation. A speaker may also find this exercise to be helpful when their mind "goes blank", as it gives them time to regain their train of thought.
Over-the-counter and prescription medications are readily available, such as dimenhydrinate, scopolamine, meclizine, promethazine, cyclizine, and cinnarizine. Cinnarizine is not available in the United States, as it is not approved by the FDA. As these medications often have side effects, anyone involved in high-risk activities while at sea (such as SCUBA divers) must evaluate the risks versus the benefits. Promethazine is especially known to cause drowsiness, which is often counteracted by ephedrine in a combination known as "the Coast Guard cocktail.". There are special considerations to be aware of when the common anti-motion sickness medications are used in the military setting where performance must be maintained at a high level.
Scopolamine is effective and is sometimes used in the form of transdermal patches (1.5 mg) or as a newer tablet form (0.4 mg). The selection of a transdermal patch or scopolamine tablet is determined by a doctor after consideration of the patient's age, weight, and length of treatment time required.
Many pharmacological treatments which are effective for nausea and vomiting in some medical conditions may not be effective for motion sickness. For example, metoclopramide and prochlorperazine, although widely used for nausea, are ineffective for motion-sickness prevention and treatment. This is due to the physiology of the CNS vomiting centre and its inputs from the chemoreceptor trigger zone versus the inner ear. Sedating anti-histamine medications such as promethazine work quite well for motion sickness, although they can cause significant drowsiness.
Ginger root is commonly thought to be an effective anti-emetic, but it is ineffective in treating motion sickness.
Cognitive therapy is a widely accepted form of treatment for most anxiety disorders. It is also thought to be particularly effective in combating disorders where the patient doesn't actually fear a situation but, rather, fears what could result from being in such a situation. The ultimate goal of cognitive therapy is to modify distorted thoughts or misconceptions associated with whatever is being feared; the theory is that modifying these thoughts will decrease anxiety and avoidance of certain situations. For example, cognitive therapy would attempt to convince a claustrophobic patient that elevators are not dangerous but are, in fact, very useful in getting you where you would like to go faster. A study conducted by S.J. Rachman shows that cognitive therapy decreased fear and negative thoughts/connotations by an average of around 30% in claustrophobic patients tested, proving it to be a reasonably effective method.
Many people report stress-induced speech disorders which are only present during public speech. Some individuals with glossophobia have been able to dance, perform in public, or even to speak (such as in a play), or sing if they cannot see the audience, or if they feel that they are presenting a character or stage persona other than themselves. Being able to blend in a group (as in a choir or band) has been reported to also alleviate some anxiety caused by glossophobia.
It has been estimated that 75% of all people experience some degree of anxiety/nervousness when it comes to public speaking. In fact, surveys have shown that most people fear public speaking more than they fear death. If untreated, public speaking anxiety can lead to serious detrimental effects on one's quality of life, career goals and other areas. For example, educational goals requiring public speaking might be left unaccomplished. However, not all persons with public speaking anxiety are necessarily unable to achieve work goals, though this disorder becomes problematic when it prevents an individual from attaining or pursuing a goal they might otherwise have - were it not for their anxiety.
A recent study conducted by Garcia-Lopez, Diez-Bedmar, and Almansa-Moreno (2013) has reported that previously trained students could act as trainers to other students and help them to improve their public speaking skills.
This method forces patients to face their fears by complete exposure to whatever fear they are experiencing. This is usually done in a progressive manner starting with lesser exposures and moving upward towards severe exposures. For example, a claustrophobic patient would start by going into an elevator and work up to an MRI. Several studies have proven this to be an effective method in combating various phobias, claustrophobia included. S.J. Rachman has also tested the effectiveness of this method in treating claustrophobia and found it to decrease fear and negative thoughts/connotations by an average of nearly 75% in his patients. Of the methods he tested in this particular study, this was by far the most significant reduction.
In some cases, education can considerably diminish concern about physical safety. Learning how aircraft fly, how airliners are flown in practice, and other aspects of aviation can reduce anxiety. Many people have dealt with the problem by learning to fly or skydive, effectively removing their fear of the unknown. Some educate themselves; others attend courses offered by pilots or airlines.
Though education plays an important role, the knowledge that turbulence will not destroy the aircraft does not stop the amygdala - the part of the brain responsible for generating most emotional responses, and via the Hypothalamic–pituitary–adrenal axis, the release of stress hormones - from reacting. In turbulence, repeated downward movements of the plane trigger one release of stress hormones after another. A build-up of stress hormones can cause a person to be terrified despite having every reason to know logically that the plane is not in danger. In such cases, therapy — in addition to education — is needed to prevent the release of stress hormones so that the anxious flier may gain relief.
Behavioral therapies such as systematic desensitization developed by Joseph Wolpe and cognitive behavior therapy developed by Aaron Beck rest on the theory that an initial sensitizing event (ISE) has created the phobia. The gradually increased exposure needed for systematic desensitization is difficult to produce in actual flight. Desensitization using virtual flight has been disappointing. Clients report that simulated flight using computer-generated images does not desensitize them to risk because throughout the virtual flight they were aware they were in an office. Research shows Virtual Reality Exposure Therapy (VRET) to be no more effective than sitting on a parked airplane. As a practical substitute for systematic desensitization, the amygdala can be taught to regard a stimulus as benign by linking it to an experience already regarded by the amygdala as benign. This alternative has been termed systematic inhibition of the amygdala.
Hypnotherapy generally involves regression to the ISE, uncovering the event, the emotions around the event, and helping the client understand the source of their fear. It is sometimes the case that the ISE has nothing to do with flying at all.
Neurological research by Allan Schore and others using EEG-fMRI neuroimaging suggests that though it may first be manifest following a turbulent flight, fear of flying is not the result of a sensitizing event. The underlying problem is inadequate development of ability to regulate emotion when facing uncertainty, except through feeling in control or able to escape. According to Schore, the ability to adequately regulate emotion fails to develop when relationship with caregivers is not characterized by attunement and empathy. "Because these mothers are unable to regulate their own distress, they cannot regulate their infant's distress." Chronic stress and emotional dysregulation during the first two years of life inhibits development of the right prefrontal orbito cortex, and hinders the integration of the emotional control system. This renders the right prefrontal orbito cortex incapable of carrying out its executive role in the regulation of emotion. Some who disagree with the importance of early experience regard this view point as contentious. However, Harvard University and the National Scientific Council on the Developing Child state, "Genes provide the basic blueprint, but experiences influence how or whether genes are expressed. Together, they shape the quality of brain architecture and establish either a sturdy or a fragile foundation for all of the learning, health, and behavior that follow."
When it senses anything unfamiliar or unexpected, the amygdala releases stress hormones. In humans, stress hormones activate both the sympathetic nervous system and executive function. The sympathetic nervous system produces an urge to mobilize. Initially, to assess the situation, executive function overrides the urge to mobilize. If assessment reveals no threat, executive function dismisses the matter, and signals the amygdala to end stress hormone release. If risk is apparent, executive function considers what can be done to deal with the risk. Upon commitment to a plan, either of action or of inaction, executive function signals the amygdala to end stress hormone release.
In a non-phobic person, the arousal caused by the release of stress hormones results in a sense of curiosity, not a sense of emergency. Phobic response is significantly different. The phobic person equates arousal with fear, and fear as proof that there is danger. Upon arousal, the person's executive function is called upon not merely to assess the situation, but - if stress hormones are to be regulated - to prove no danger exists. If danger cannot be ruled out, executive function can no longer inhibit the urge to mobilize. Though phobics regard control as the antidote to fear, it is commitment to a plan - not control alone that ends the release of stress hormones. If a person has control but cannot commit to a plan, fear persists. It is interesting to note that commitment to any action - even unwise action - provides relief, and signals the amygdala to terminate stress hormone release.
If a phobic flier were able to fly in the cockpit, the pilot's facial response to an unexpected noise or motion would adequately prove the absence of danger. But with information in the cabin limited, it is impossible to prove no danger exists. Stress hormones continue to be released. As levels rise, anxiety increases and the urge to escape becomes paramount. Since physical escape is impossible, panic may result unless the person can escape psychologically through denial, dissociation, or distraction.
In the cognitive approach, the passenger learns to separate arousal from fear, and fear from danger. Cognitive therapy is most useful when there is no history of panic. But since in-flight panic develops rapidly, often through processes which the person has no awareness of, conscious measures may neither connect with - nor match the speed of - the unconscious processes that cause panic.
In another approach, emotion is regulated by what neuroscientist Stephen Porges calls neuroception. In social situations, arousal is powerfully regulated by signals people unconsciously send, receive, and process. For example, when encountering a stranger, stress hormone release increases the heart rate. But if the stranger's signals indicate trustworthiness, these signals override the effect of stress hormones, slow the heart, calm the person, and allow social interaction to take place. Because neuroception can completely override the effect of stress hormones, can be controlled by linking the noises and motions of flight to neuroceptive signals that calm the person.
Lastly, frequent flyer experts at Flightfox suggest that fear of flying is a reaction caused by the panic and tension of so many travellers in close quarters - once one person is uneasy the rest soon feel uncomfortable as well. Their solution, odd as it may seem, is to fly in premium class to experience flying in a comfortable and relaxed setting, so as to avoid the tension and anxiety of coach.
Travelling west causes fewer problems than travelling east, and it is usually sufficient to seek exposure to light during the day and avoid it at night.
Involutional melancholia is classically treated with antidepressants and mood elevators.
Electroconvulsive therapy may also be used. Mid-century, there was a consensus that the technique indeed 'yields the best results in the long-lasting depressions of the change of life, the so-called "involutional melancholias", which before this form of treatment was introduced often required years of hospitalization'. The 21st century also records 'an excellent and rapid clinical response found in melancholia of recent onset...in older rather than younger patients' with ECT
When someone starts to feel the sensation of being scared or nervous they start to experience anxiety. According to a Harvard Mental Health Letter, "Anxiety usually has physical symptoms that may include a racing heart, a dry mouth, a shaky voice, blushing, trembling, sweating, lightheadedness, and nausea". It triggers the body to activate its sympathetic nervous system. This process takes place when the body releases adrenaline into the blood stream causing a chain of reactions to occur. This bodily response is known as the "fight or flight" syndrome, a naturally occurring process in the body done to protect itself from harm. "The neck muscles contract, bringing the head down and shoulders up, while the back muscles draw the spine into a curve. This, in turn, pushes the pelvis forward and pulls the genitals up, slumping the body into a classic fetal position".
In trying to resist this position, the body will begin to shake in places such as the legs and hands. Several other things happen besides this. Muscles in the body contract, causing them to be tense and ready to attack. Second, "blood vessels in the extremities constrict". This can leave a person with the feeling of cold fingers, toes, nose, and ears. Constricted blood vessels also gives the body extra blood flow to the vital organs.
In addition, those experiencing stage fright will have an increase in blood pressure, which supplies the body with more nutrients and oxygen in response to the "fight or flight" instincts. This, in return, causes the body to overheat and sweat. Breathing will increase so that the body can obtain the desired amount of oxygen for the muscles and organs. Pupils will dilate giving someone the inability to view any notes they have in close proximity; however, long range vision is improved making the speaker more aware of their audience's facial expressions and nonverbal cues in response to the speaker's performance. Lastly, the digestive system shuts down to prepare for producing energy for an immediate emergency response. This can leave the body with the effects of dry mouth, nausea, or butterflies.
Special education classes are the primary treatment. These classes focus on activities that sustain growth in language skills. The foundation of this treatment is repetition of oral, reading and writing activities. Usually the SLP, psychologist and the teacher work together with the children in small groups in the class room.
Another treatment is looking at a child's needs through the Individual Education Plan (IEP). In this program teachers and parents work together to monitor the progress of the child's comprehensive, verbal, written, social, and motor skills in school and in the home. Then the child goes through different assessments to determine his/her level. The level that the child is placed in will determine the class size, number of teachers, and the need for therapy.
Stage fright or performance anxiety is the anxiety, fear, or persistent phobia which may be aroused in an individual by the requirement to perform in front of an audience, whether actually or potentially (for example, when performing before a camera). In the context of public speaking, this may precede or accompany participation in any activity involving public self-presentation. In some cases stage fright may be a part of a larger pattern of social phobia (social anxiety disorder), but many people experience stage fright without any wider problems. Quite often, stage fright arises in a mere anticipation of a performance, often a long time ahead. It has numerous manifestations: stuttering, tachycardia, tremor in the hands and legs, sweaty hands, facial nerve tics, dry mouth, and dizziness.
As astronauts frequently have motion sickness, NASA has done extensive research on the causes and treatments for motion sickness. One very promising looking treatment is for the person suffering from motion sickness to wear LCD shutter glasses that create a stroboscopic vision of 4 Hz with a dwell of 10 milliseconds.
Pressured speech may also lead to the development of a stutter. The person's need or pressure to speak causes them to involuntarily stutter. Therefore, the person's need to express themselves is greater than their ability to vocalise their thoughts.
Medications that may alleviate the symptoms of airsickness include:
- meclozine
- dimenhydrinate
- diphenhydramine
- scopolamine (available in both patch and oral form).
Pilots who are susceptible to airsickness should not take anti-motion sickness medications (prescription or over-the-counter). These medications can make one drowsy or affect brain functions in other ways.
There are numerous alternative remedies for motion sickness. One such is ginger, but it is ineffective.
The standard approach to treatment is the same as with other phobias - cognitive-behavioral therapy, desensitization, and possibly medications to help with the anxiety and discomfort. In recent years, the technique known as "applied tension", applying tension to the muscles in an effort to increase blood pressure, has increasingly gained favor as an often effective treatment for blood phobia associated with drops in blood pressure and fainting.
Because the fear of blood is extremely common, it is frequently exploited in popular culture. Horror movies and Halloween events prey on our natural aversion to blood, often featuring large quantities of fake blood.
Mood stabilizers are often used as part of the treatment process.
1. Lithium is the mainstay in the management of bipolar disorder but it has a narrow therapeutic range and typically requires monitoring
2. Anticonvulsants, such as sodium valproate, carbamazepine or lamotrigine
3. Antipsychotics, such as quetiapine, risperidone, olanzapine or aripiprazole
4. Electroconvulsive therapy, a psychiatric treatment in which seizures are electrically induced in anesthetized patients for therapeutic effect
Some antidepressants, like venlafaxine, have been found to precipitate a manic episode.
CSC should be done as soon as possible when operations permit. Intervention is provided as soon as symptoms appear.
LBLD can be an enduring problem. Some people might experience overlapping learning disabilities that make improvement problematic. Others with single disabilities often show more improvement. Most subjects can achieve literacy via coping mechanisms and education.
Psychostimulants such as cocaine, amphetamines may cause speech resembling pressured speech in individuals with pre-existing psychopathology and produce hypomanic or manic symptoms in general, owing both to the substance's own qualities and the underlying nature of an individual's psyche. In many psychotic disorders, use of certain drugs amplifies certain expressions of symptoms, and stimulant-induced pressured speech is among them.
Word salad can be generated by a computer program for entertainment purposes by inserting randomly chosen words of the same type (nouns, adjectives, etc.) into template sentences with missing words, a game similar to Mad Libs. The video game company Maxis, in their seminal SimCity 2000, used this technique to create an in-game "newspaper" for entertainment; the columns were composed by taking a vague story-structure, and using randomization, inserted various nouns, adjectives, and verbs to generate seemingly unique stories.
Another way of generating meaningless text is mojibake, also called "Buchstabensalat" ("letter salad") in German, in which an assortment of seemingly random text is generated through character encoding incompatibility in which one set of characters are replaced by another, though the effect is more effective in languages where each character represents a word, such as Chinese, than a letter.
More serious attempts to produce nonsense automatically stem from Claude Shannon's seminal paper "A Mathematical Theory of Communication" from 1948
where progressively more convincing nonsense is generated first by choosing letters and spaces randomly, then according to the frequency with which each character appears in some sample of text, then respecting the likelihood that the chosen letter appears after the preceding one or two in the sample text, and then applying similar techniques to whole words. Its most convincing nonsense is generated by second-order word approximation, in which words are chosen by a random function weighted to the likeliness that each word follows the preceding one in normal text:
THE HEAD AND IN FRONTAL ATTACK ON AN ENGLISH WRITER THAT THE CHAR-
ACTER OF THIS POINT IS THEREFORE ANOTHER METHOD FOR THE LETTERS THAT
THE TIME OF WHO EVER TOLD THE PROBLEM FOR AN UNEXPECTED.
Markov chains can be used to generate random but somewhat human-looking sentences. This is used in some chat-bots, especially on IRC-networks.
Nonsensical phrasing can also be generated for more malicious reasons, such as the Bayesian poisoning used to counter Bayesian spam filters by using a string of words which have a high probability of being collocated in English, but with no concern for whether the sentence makes sense grammatically or logically.
Before beginning treatment for mania, careful differential diagnosis must be performed to rule out secondary causes.
The acute treatment of a manic episode of bipolar disorder involves the utilization of either a mood stabilizer (valproate, lithium, or carbamazepine) or an atypical antipsychotic (olanzapine, quetiapine, risperidone, or aripiprazole). Although hypomanic episodes may respond to a mood stabilizer alone, full-blown episodes are treated with an atypical antipsychotic (often in conjunction with a mood stabilizer, as these tend to produce the most rapid improvement).
When the manic behaviours have gone, long-term treatment then focuses on prophylactic treatment to try to stabilize the patient's mood, typically through a combination of pharmacotherapy and psychotherapy. The likelihood of having a relapse is very high for those who have experienced two or more episodes of mania or depression. While medication for bipolar disorder is important to manage symptoms of mania and depression, studies show relying on medications alone is not the most effective method of treatment. Medication is most effective when used in combination with other bipolar disorder treatments, including psychotherapy, self-help coping strategies, and healthy lifestyle choices.
Lithium is the classic mood stabilizer to prevent further manic and depressive episodes. A systematic review found that long term lithium treatment substantially reduces the risk of bipolar manic relapse, by 42%. Anticonvulsants such as valproate, oxcarbazepine and carbamazepine are also used for prophylaxis. More recent drug solutions include lamotrigine, which is another anticonvulsant. Clonazepam (Klonopin) is also used. Sometimes atypical antipsychotics are used in combination with the previous mentioned medications as well, including olanzapine (Zyprexa) which helps treat hallucinations or delusions, Asenapine (Saphris, Sycrest), aripiprazole (Abilify), risperidone, ziprasidone, and clozapine which is often used for people who do not respond to lithium or anticonvulsants.
Verapamil, a calcium-channel blocker, is useful in the treatment of hypomania and in those cases where lithium and mood stabilizers are contraindicated or ineffective. Verapamil is effective for both short-term and long-term treatment.
Antidepressant monotherapy is not recommended for the treatment of depression in patients with bipolar disorders I or II, and no benefit has been demonstrated by combining antidepressants with mood stabilizers in these patients.
Nyctophobia is a phobia characterized by a severe fear of the dark. It is triggered by the brain’s disfigured perception of what would, or could happen when in a dark environment. It can also be temporarily triggered if the mind is unsteady or scared about recent events or ideas, or a partaking in content the brain considers a threat (examples could include indulging in horror content, witnessing vulgar actions, or having linked dark environments to prior events or ideas that disturb the mind). Normally, since humans are not nocturnal by nature, humans are usually a bit more cautious or alert at night than in the day, since the dark is a vastly different environment. Nyctophobia produces symptoms beyond the normal instinctive parameters, such as breathlessness, excessive sweating, nausea, dry mouth, feeling sick, shaking, heart palpitations, inability to speak or think clearly or sensation of detachment from reality and death. Nyctophobia can be severely detrimental physically and mentally if these symptoms are not resolved. There are many types of therapies to help manage Nyctophobia. Exposure therapy can be very effective when exposing the person to darkness. With this method a therapist can help with relaxation strategies such as meditation. Another form of therapy is Cognitive Behavioral Therapy. Therapists can help guide patients with behavior routines that are performed daily and nightly to reduce the symptoms associated with Nyctophobia. In severe cases anti-depressants and anti-anxiety medication drugs can be effective to those dealing with symptoms that may not be manageable if therapy could not reduce the symptoms of Nyctophobia.
Despite its pervasive nature, there has been a lack of etiological research on the subject. Nyctophobia is generally observed in children but, according to J. Adrian Williams’ article titled, "Indirect Hypnotic Therapy of Nyctophobia: A Case Report", many clinics with pediatric patients have a great chance of having adults who have nyctophobia. The same article states that “the phobia has been known to be extremely disruptive to adult patients and… incapacitating”.
The word "nyctophobia" comes from the Greek νυκτός, "nyktos", genitive of νύξ, "nyx", "night" and φόβος, "phobos", "fear". The fear of darkness or night has several non-clinical terminologies—"lygophobia", "scotophobia" and "achluophobia".
