Morgellons is poorly understood but the general medical consensus is that it is a form of delusional parasitosis in which individuals have some form of actual skin condition that they believe contains some kind of fibers.

The following are some of the common symptoms of RHS:

- Depression

- Skin rash

- Asthma

- Ulcers

- High blood pressure

This syndrome was identified and coined by Nobuo Kurokawa and first appeared in a presentation of his to the Japanese Society of Psychosomatic Medicine in 1991. It is a condition where a woman begins to exhibit signs of physical illness and depression as her husband reaches, or approaches, retirement.

Kurokawa has theorized that RHS is a result of the fact that many of Japan's citizens who are reaching retirement age, 60, are members of the Baby Boomer generation of Japan. The members of this generation were expected to meet certain social requirements: that the man should be the breadwinner and work to support his family, and the woman was to be not only a homemaker but also to show a level of adoration for her salaryman husband as reward for his bringing in the money she used to look after their children and socialize with her friends.

As the husband's career as a salaryman can demand long hours away from home, both working and socializing with other salarymen and their bosses as is expected, a husband may leave home in the early hours of the morning and return home late at night. This could mean that a husband and wife may not interact extensively and when a husband retires both members of the couple can feel they are living together with someone who is a virtual stranger.

This can be a particularly stressful experience for the woman who, as society dictated in her youth, is expected to attend to her husband's every need and can find this a very large demand indeed. The stress this change in life style brings can lead not only to the above listed symptoms, but also to a level of resentment felt toward her husband. Some couples have been known to separate over RHS, however divorce is uncommon as it is not considered an acceptable option for that generation of Japanese. Also currently an ex-wife has no rights to a portion of her husband's pension should they divorce, and therefore may be unable to survive financially (though this was set to change in 2007). Despite this, the divorce rate among older Japanese couples has soared in recent decades, as more of the baby boomer population have retired, increasing by 26.5% in 10 years according to the health ministry. The number of divorces among couples married for 20 years or more hit 42,000 in 2004, double those recorded in 1985. Divorces among those married for more than 30 years quadrupled during the same period. In 2006, these figures were projected to rise further as more Japanese people were expected to retire in the subsequent five years than at any other point in Japanese history.

Some women deal with RHS by focusing their energy on obsessions such as collecting teddy bears, or following a celebrity, which they say can help them psychologically. They may also ask their husbands to stay on at work past retirement age. Many wives do not tell their husbands what is happening and this can worsen the stress as their husbands may not understand or even realize their wives are RHS sufferers.

Morgellons (/mɔː(ɹ)ˈdʒɛlənz/) is the informal name of a self-diagnosed skin condition in which individuals have sores that they believe contain some kind of fibers. Morgellons is poorly understood but the general medical consensus is that it is a form of delusional parasitosis; the sores are the result of compulsive scratching, and the fibers, when analysed, turn out to originate from textiles.

The name was coined in 2002 by Mary Leitao, a mother who rejected the medical diagnosis of her son's delusional parasitosis. She revived it from a letter written by a physician in the mid-17th century. Leitao and others involved in her Morgellons Research Foundation successfully lobbied members of the U.S. Congress and the U.S. Centers for Disease Control and Prevention (CDC) to investigate the condition in 2006. CDC researchers issued the results of their multi-year study in January 2012, indicating that there were no disease organisms present in people with Morgellons and that the fibers found were likely cotton, and concluded that the condition was "similar to more commonly recognized conditions such as delusional infestation".

The 2007 Tour de France was affected by a series of scandals and speculations related to doping. By the end of the Tour, two cyclists were dismissed for failing tests and the wearer of the yellow jersey was voluntarily retired by his team for lying about his whereabouts and missing doping tests. A fourth rider was confirmed to having used doping while in a training session prior to the 2007 Tour and a fifth rider failed tests late in the race, with his result being officially announced just after the end of the Tour. During the competition, two teams were asked to withdraw after at least one member was found to have doped.

The events generated criticism and a general distrustful attitude toward the sport of professional cycling from media and public opinion. The doping allegations also resulted in several team sponsors threatening to retire their support if events advanced further. Some media such as German TV channels ARD and ZDF left the Tour once the first scandals broke. Following the Tour's conclusion, the sport's governing bodies spoke out about ways to combat the prevalence of doping in cycling and key team sponsors elected to withdraw their support due to the reputational damage caused by the scandals. The 2007 Tour de France has been referred to as one of the most controversial Tours. After the end of the Tour, "The Times" of London ranked it 4th in its list of the top 50 sporting scandals.

When the Malays were asked why they thought that women were more likely to suffer from latah, they responded with the cultural explanation that women have less 'semangat' or soul substance. They also said women are simply easier to tease than men, and coupling these two together: latah becomes more readily observable and developed throughout recurrent provocation in women than in men. This also accounts for the higher prevalence of latah in lower status persons, as they are more vulnerable to abuse than others. The Malay also believe women are more susceptible because they lose more blood than men, through menstruation. Some Malay believe that excess tickling of a child will predispose them to latah later in life.

Western doctors are more likely to diagnose it as a kind of stress or depression. The "Diagnostic and Statistical Manual of Mental Disorders" currently lists "hwabyeong" among its culture-bound illnesses. Outside of Korea, informally "hwabyeong" may be mistaken as a reference to a psychological profile marked by a short temper, or explosive, generally bellicose behavior. To the contrary, "hwabyeong" is a traditional psychological term used to refer to a condition characterized by passive suffering, is roughly comparable to depression, and is typically associated with older women. It is important that when diagnosing Hwabyeong, the culture of the patient is well understood. Since Hwabyeong can often be misdiagnosed as depression, the symptoms and culture need to be clearly and thoroughly looked into. Once Hwabyeong has been diagnosed, past treatments need to be reviewed. The treatments for the patient can then be a combination of pharmacological, and therapy-based interventions.

The treatment methods used to combat hwabyung include psychotherapy, drug treatment, family therapy, and community approaches. To be more successful psychiatrists might need to incorporate the teachings from traditional and religious healing methods or the use of han-puri, which is the sentiment of resolving, loosening, unraveling and appeasing negative emotions with positive ones. One example of hann-puri would be a mother who has suffered from poverty, less education, a violent husband, or a harsh mother-in-law, can be solved many years later by the success of her son for which she had endured hardships and sacrifices.

The onset of Latah is often associated with stress. In a study done by Tanner and Chamberland in 2001, a significant number of research participants had experienced a life stressor (such as a child or husband dying) just before becoming latah. Additionally, a large number of participants from many research studies have reported strange dreams occurring just before the onset of latah. These dreams usually had a sexual element to them, often involving penises or enlarged penises. According to Tanner and Chamberland, perhaps the dreams, although with variation, indicate some sort of dysfunction in a specific anatomical area. Exploring this further might lead to more insights as to the cause and/or cure of latah.

Osborne (2001) states that latah is a possible emotional outlet in a stifling culture. Winzeler’s believes that latah is less demeaning for women than it is for men, and that women actually have more freedom in society because they are not held to as strict of standards as men are. He argues that as men age, they become more concerned with personal dignity and poise while women become less so. Because of this, women feel more freedom to engage in latah behavior, while men do not.

The Frontier Middle School shooting was a school shooting that occurred on February 2, 1996, at Frontier Middle School in Moses Lake, Washington, United States. The gunman, 14-year-old Barry Dale Loukaitis (born February 26, 1981), killed his algebra teacher and two students, and held his classmates hostage for over an hour before a gym coach subdued Loukaitis.

Hwabyeong or Hwabyung is a Korean somatization disorder, a mental illness which arises when people are unable to confront their anger as a result of conditions which they perceive to be unfair.

Hwabyung is a colloquial and somewhat inaccurate name, as it refers to the etiology of the disorder rather than its symptoms or apparent characteristics. Hwabyung is known as a culture-bound syndrome. The word hwabyung is composed of "hwa" (the Sino-Korean word for "fire" which can also contextually mean "anger") and "byung" (the Sino-Korean word for "syndrome" or "illness"). In South Korea, it may also be called "ulhwabyeong" (), literally "depression anger illness". In one survey, 4.1% of the general population in a rural area in Korea were reported as having hwabyung. Another survey shows that about 35% of Korean workers are affected by this condition at some time.

A cuckold is the husband of an adulterous wife. In evolutionary biology, the term is also applied to males who are unwittingly investing parental effort in offspring that are not genetically their own.

Ordinal-linguistic personification (OLP, or personification for short) is a form of synesthesia in which ordered sequences, such as ordinal numbers, days, months and letters are associated with personalities and/or genders (). Although this form of synesthesia was documented as early as the 1890s (; ) researchers have, until recently, paid little attention to this form (see History of synesthesia research).

Munchausen by Internet is a pattern of behavior akin to Munchausen syndrome (renamed factitious disorder imposed on self), a psychiatric disorder, wherein those affected feign disease, illness, or psychological trauma to draw attention, sympathy, or reassurance to themselves. In Munchausen by internet, users seek attention by feigning illnesses in online venues such as chat rooms, message boards, and Internet Relay Chat (IRC). It has been described in medical literature as a manifestation of factitious disorder imposed on self, or if claiming illness of a child or other family member, factitious disorder imposed on another. Reports of users who deceive Internet forum participants by portraying themselves as gravely ill or as victims of violence first appeared in the 1990s due to the relative newness of Internet communications. The pattern was identified in 1998 by psychiatrist Marc Feldman, who created the term "Münchausen by Internet" in 2000. It is not included in the fifth revision of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-5).

The development of factitious disorders in online venues is made easier by the availability of medical literature on the Internet, the anonymous and malleable nature of online identities, and the existence of communication forums established for the sole purpose of giving support to members facing significant health or psychological problems. Several high-profile cases have demonstrated behavior patterns which are common among those who pose as gravely ill or as victims of violence, or whose deaths are announced to online forums. The virtual communities that were created to give support, as well as general non-medical communities, often express genuine sympathy and grief for the purported victims. When fabrications are suspected or confirmed, the ensuing discussion can create schisms in online communities, destroying some and altering the trusting nature of individual members in others.

The term "Munchausen by Internet" was first used in an article published in the "Southern Medical Journal" written by Marc Feldman in 2000. Feldman, a clinical professor of psychiatry at the University of Alabama at Birmingham, gave a name to the phenomenon in 2000, but he co-authored an article on the topic two years earlier in the "Western Journal of Medicine", using the description "virtual factitious disorder". Factitious disorders are described in the "Diagnostic and Statistical Manual of Mental Disorders: DSM-IV-TR" (DSM) as psychological disorders involving the production of non-existent physical or psychological ailments to earn sympathy. These illnesses are feigned not for monetary gain or to avoid inconvenient situations, but to attract compassion or to control others. Chronic manifestation of factitious disorder is often called Munchausen syndrome, after a book about the exaggerated accounts of the adventures of Baron Munchausen, a German cavalry officer in the Russian Army, that was written by Rudolf Erich Raspe. When the symptoms of another person, such as a child or an elderly parent, are purposely induced by the caregiver, it is called factitious disorder imposed on another, or Munchausen syndrome by proxy.

Feldman noted that the advent of online support groups, combined with access to vast stores of medical information, enabled individuals seeking to gain sympathy by relating a series of harrowing medical or psychological problems that defy comprehension to misuse the groups. Communication forums specializing in medical or psychological recovery were established to give lay users support in navigating often confusing and frustrating medical processes and bureaucracy. Communities often formed on those forums, with the goal of sharing information to help other members. Medical websites also became common, giving lay users access to literature in a way that was accessible to those without specific medical training. As Internet communication grew in popularity, users began to forgo the doctors and hospitals often consulted for medical advice. Frequenting virtual communities that have experience with a medical problem, Feldman notes, is easier than going through the physical pain or illness that would be necessary before visiting a doctor to get the attention sought. By pretending to be gravely ill, Internet users can gain sympathy from a group whose sole reason for existence is support. Health care professionals, with their limited time, greater medical knowledge, and tendency to be more skeptical in their diagnoses, may be less likely to provide that support.

Anorexia mirabilis literally means "miraculous lack of appetite". It refers almost exclusively to women and girls of the Middle Ages who would starve themselves, sometimes to the point of death, in the name of God. The phenomenon is also known by the name inedia prodigiosa ("prodigious fasting").

Ronnie and Donnie Galyon (born October 28, 1951) are two American conjoined twins. According to the 2009 "Guinness World Records", the Galyons are the oldest living set of conjoined twins in the world, and, as of 29 October 2014, possess the world record for the longest-lived conjoined twins in history.

They were born at St. Elizabeth Hospital in Dayton, Ohio, on 28 October 1951, to Wesley and Eileen Galyon; Eileen was not expecting twins. They were joined from the sternum to the groin and shared a set of organs, so they could not be separated. Local schools deemed the twins a distraction and they were subsequently never formally educated, resulting in their lifelong functional illiteracy.

With nine children to support, their father Wesley decided to take the twins on the road as a sideshow attraction. The boys were exhibited in sideshows throughout the US and later in Latin America. Their tours made them celebrities and provided an income with which they supported their family. The twins also tried to join the Army, but were ranked 4F.

In 1991, after three decades in entertainment, the pair retired and moved into their first independent home in Dayton, Ohio, in a house purchased with sideshow earnings. They were active in the community and lived a largely normal life by means of a custom double wheelchair. Although retired from show business, the twins made numerous television appearances. They appeared on "The Jerry Springer Show" in 1997, a Discovery Channel documentary in 1998 and a Channel Five documentary in 2009.

In 2009, Ronnie suffered a life-threatening infection in his lungs, which quickly endangered both twins. After their hospitalization, they required round-the-clock care. Their younger brother Jim and his wife Mary, who lived in the same town, were unable to bring the twins into their home as it was not handicap accessible, until an outpouring of donations and volunteers from the local community assisted in building a special addition to the home. On December 22, 2010, TLC premiered "The World's Oldest Conjoined Twins Move Home," which documented the building process as well as the twins' recovery and their return to the community.

Foot binding was the custom of applying tight binding to the feet of young girls to modify the shape of their feet. The practice possibly originated among upper class court dancers during the Five Dynasties and Ten Kingdoms period in 10th century China, then became popular among the elite during the Song dynasty and eventually spread to all social classes by the Qing dynasty. Foot binding became popular as a means of displaying status (women from wealthy families, who did not need their feet to work, could afford to have them bound) and was correspondingly adopted as a symbol of beauty in Chinese culture. Foot binding limited the mobility of women, resulting in them walking in a swaying unsteady gait, although some women with bound feet working outdoor had also been reported. The prevalence and practice of foot binding varied in different parts of the country. Feet altered by binding were called lotus feet.

It has been estimated that by the 19th century, 40–50% of all Chinese women may have had bound feet, and up to almost 100% among upper class Han Chinese women. The Manchu Kangxi Emperor tried to ban foot binding in 1664 but failed. In the later part of the 19th century, Chinese reformers challenged the practice but it was not until the early 20th century that foot binding began to die out as a result of anti-foot-binding campaigns. Foot-binding resulted in lifelong disabilities for most of its subjects, and a few elderly Chinese women still survive today with disabilities related to their bound feet.

Hoplophobia is a political neologism coined by retired American military officer Jeff Cooper as a pejorative to describe an "irrational aversion to weapons." It is also used to describe the "fear of firearms" or the "fear of armed citizens." Hoplophobia is a political term and not a recognized medical phobia.

The Hungerford massacre was a series of random shootings in Hungerford, England, United Kingdom, on 19 August 1987, when Michael Robert Ryan, an unemployed antique dealer and handyman, fatally shot 16 people, including a police officer, before taking his own life. The shootings, committed using a handgun and two semi-automatic rifles, occurred at several locations, including a school he had once attended. 15 other people were also shot but survived. No firm motive for the killings has ever been established, although one psychologist has theorised Ryan's motive for the massacre had been a form of "anger and contempt for the ordinary life" around him, which he himself was not a tangible part of.

A report was commissioned by Home Secretary Douglas Hurd. The Firearms (Amendment) Act 1988 was passed in the wake of the massacre, which bans the ownership of semi-automatic centre-fire rifles and restricts the use of shotguns with a capacity of more than three cartridges. The shootings remain one of the deadliest firearms incidents in British history.

Folie à deux (; ; French for "madness of two"), or shared psychosis, is a psychiatric syndrome in which symptoms of a delusional belief and sometimes hallucinations are transmitted from one individual to another. The same syndrome shared by more than two people may be called "folie à trois", "folie à quatre", "folie en famille" ("family madness"), or even "folie à plusieurs" ("madness of many").

Recent psychiatric classifications refer to the syndrome as shared psychotic disorder (DSM-IV – 297.3) and induced delusional disorder (F24) in the ICD-10, although the research literature largely uses the original name. This disorder is not in the current DSM (DSM-5). The disorder was first conceptualized in 19th-century French psychiatry by Charles Lasègue and Jean-Pierre Falret and is also known as Lasègue-Falret syndrome.

Mme L. reports that “1, 2, 3 are children without fixed personalities; they play together. 4 is a good peaceful woman, absorbed by down-to-earth occupations and who takes pleasure in them. 5 is a young man, ordinary and common in his tastes and appearance, but extravagant and self-centered. 6 is a young man of 16 or 17, very well brought up, polite, gentle, agreeable in appearance, and with upstanding tastes; average intelligence; orphan. 7 is a bad sort, although brought up well; spiritual, extravagant, gay, likeable; capable of very good actions on occasion; very generous. 8 is a very dignified lady, who acts appropriately, and who is linked with 7 and has much influence on him. She is the wife of 9. 9 is the husband of 8. He is self-centred, maniacal, selfish, thinks only about himself, is grumpy, endlessly reproaching his wife for one thing or another; telling her, for example, that he would have been better to have married a 9, since between them they would have made 18 – as opposed to only 17 with her… 10, and the other remaining numerals, have no personifications”.

Cakins (1893) describes a case for whom “T’s are generally crabbed, ungenerous creatures. U is a soulless sort of thing. 4 is honest, but… 3 I cannot trust… 9 is dark, a gentleman, tall and graceful, but politic under his suavity” .

For synesthete MT “I [is] a bit of a worrier at times, although easy-going; J [is] male; appearing jocular, but with strength of character; K [is] female; quiet, responsible…” .

More recently AP has reported that February is “an introverted female”, while F is a “[male] dodgy geezer”. Similarly, May is reported to be “soft-spoken” and “girly” while M is an “old lady [who] natter[s] a lot”, and while August is “a boy among girls”, A is a female “mother type” (; ).

The most common problem with bound feet was infection. Despite the amount of care taken in regularly trimming the toenails, they would often in-grow, becoming infected and causing injuries to the toes. Sometimes for this reason the girl's toenails would be peeled back and removed altogether. The tightness of the binding meant that the circulation in the feet was faulty, and the circulation to the toes was almost cut off, so any injuries to the toes were unlikely to heal and were likely to gradually worsen and lead to infected toes and rotting flesh. The necrosis of the flesh would also initially give off a foul odour, and later the smell may come from various microorganisms that colonized the folds.

If the infection in the feet and toes entered the bones, it could cause them to soften, which could result in toes dropping off; although, this was seen as a benefit because the feet could then be bound even more tightly. Girls whose toes were more fleshy would sometimes have shards of glass or pieces of broken tiles inserted within the binding next to her feet and between her toes to cause injury and introduce infection deliberately. Disease inevitably followed infection, meaning that death from septic shock could result from foot-binding, and a surviving girl was more at risk for medical problems as she grew older. It is thought that as many as 10% of girls may have died from gangrene and other infections due to footbinding.

At the beginning of the binding, many of the foot bones would remain broken, often for years. However, as the girl grew older, the bones would begin to heal. Even after the foot bones had healed, they were prone to re-breaking repeatedly, especially when the girl was in her teenage years and her feet were still soft. Bones in the girls' feet would often be deliberately broken again in order to improve the size or the shape of the feet. This was especially the case with the toes, as small toes were especially desirable. Older women were more likely to break hips and other bones in falls, since they could not balance securely on their feet, and were less able to rise to their feet from a sitting position. Other issues that might arise from foot binding included paralysis and muscular atrophy.

According to Michael First of the DSM-5 working committee the focus of a relational disorder, in contrast to other DSM-IV disorders, "is on the relationship rather than on any one individual in the relationship".

Relational disorders involve two or more individuals and a disordered "juncture", whereas typical Axis I psychopathology describes a disorder at the individual level. An additional criterion for a relational disorder is that the disorder cannot be due solely to a problem in one member of the relationship, but requires pathological interaction from each of the individuals involved in the relationship.

For example, if a parent is withdrawn from one child but not another, the could be attributed to a relational disorder. In contrast, if a parent is withdrawn from both children, the dysfunction may be more appropriately attributable to a disorder at the individual level.

First states that "relational disorders share many elements in common with other disorders: there are distinctive features for classification; they can cause clinically significant impairment; there are recognizable clinical courses and patterns of comorbidity; they respond to specific treatments; and they can be prevented with early interventions. Specific tasks in a proposed research agenda: develop assessment modules; determine the clinical utility of relational disorders; determine the role of relational disorders in the etiology and maintenance of individual disorders; and consider aspects of relational disorders that might be modulated by individual disorders."

The proposed new diagnosis defines a relational disorder as "persistent and painful patterns of feelings, behaviors, and perceptions" among two or more people in an important personal relationship, such a husband and wife, or a parent and children.

According to psychiatrist Darrel Regier, MD, some psychiatrists and other therapists involved in couples and marital counseling have recommended that the new diagnosis be considered for possible incorporation into the Diagnostic and Statistical Manual of Mental Disorders (DSM IV).

The American psychologist David P. Boder assisted in identifying the term musselman when in 1946 he conducted interviews with camp survivors in Europe. He asked them to describe, spell and pronounce the word for camp inmates so emaciated that they had lost the will to live.

Primo Levi tried to explain the term (he also uses "Musselman"), in a footnote of "If This Is a Man", his autobiographical account of his time in Auschwitz:

The psychologist and Auschwitz survivor Viktor Frankl, in his book "Man's Search for Meaning", provides the example of a prisoner who decides to use up his last cigarettes (used as currency in the concentration camps) in the evening because he is convinced he won't survive the "Appell" (roll call assembly) the next morning; his fellow captives derided him as a "Muselmann". Frankl compares this to the dehumanized behavior and attitudes of the kapos.

The testimonial of the Polish witness, Adolf Gawalewicz, "Refleksje z poczekalni do gazu: ze wspomnień muzułmana" ("Reflec­tions in the Gas Chamber's Waiting Room: From the Memoirs of a Muselmann"), published in 1968, incorporates the term in the title of the work.

Canadian Jewish author Eli Pfefferkorn published a novel in 2011 with title The Müselmann at the Water Cooler.

This syndrome is most commonly diagnosed when the two or more individuals concerned live in proximity and may be socially or physically isolated and have little interaction with other people. Various sub-classifications of "folie à deux" have been proposed to describe how the delusional belief comes to be held by more than one person :

- Folie imposée is where a dominant person (known as the 'primary', 'inducer' or 'principal') initially forms a delusional belief during a psychotic episode and imposes it on another person or persons (known as the 'secondary', 'acceptor' or 'associate') with the assumption that the secondary person might not have become deluded if left to his or her own devices. If the parties are admitted to hospital separately, then the delusions in the person with the induced beliefs usually resolve without the need of medication.

- Folie simultanée describes either the situation where two people considered to suffer independently from psychosis influence the content of each other's delusions so they become identical or strikingly similar, or one in which two people "morbidly predisposed" to delusional psychosis mutually trigger symptoms in each other.

Folie à deux and its more populous cousins are in many ways a psychiatric curiosity. The current Diagnostic and Statistical Manual of Mental Disorders states that a person cannot be diagnosed as being delusional if the belief in question is one "ordinarily accepted by other members of the person's culture or subculture" (see entry for delusion). It is not clear at what point a belief considered to be delusional escapes from the "folie à..." diagnostic category and becomes legitimate because of the number of people holding it. When a large number of people may come to believe obviously false and potentially distressing things based purely on hearsay, these beliefs are not considered to be clinical delusions by the psychiatric profession and are labelled instead as mass hysteria.
