In most cases Wild Pig Syndrome will run its course, and no treatment is needed. In severe cases the individual will return to the village in the wild state, in which the individual is captured and a ceremony is held where the individual is restrained over a smoking fire until he returns to his normal state. Then the individual is rubbed down with liquefied pig fat; a small pig is killed in his name by a person of high status in the village, then afterward the individual is presented with a collection of cooked tubers and roots.

The wild man syndrome also known as wild pig syndrome is a culture-bound syndrome that affects the mental health of New Guinean males in which they become hyperactive, clumsy, kleptomaniacal, and conveniently amnesic." It is known in various languages of New Guinea as "guria", "longlong", or "lulu".

"Wild-pig syndrome is a socially constructed disorder with an emotion classification of the Gururumba tribe. The illness is characterized by involuntary antisocial behavior, followed by situational amnesia and the resumption of normal life. After looting neighbors’ homes, the tribesman (usually a recently married male) ventures into the forest for several days, returning without the stolen articles. Wild-pig attacks seem to occur when a man is unable to meet his financial obligations. Those who have undergone the episodes later receive special consideration from creditors. The Gururumba people insist the illness is transmitted by the ghosts of recently deceased tribe members."

Wild pig syndrome is limited by age and sex. It only occurs in males and only men who are 25 to 35 years of age. The syndrome is treated as a disease. The behavior is an action; however, it is not acknowledged as such by society or the individual that is experiencing the condition.

Some research suggests there is a genetic basis for greed. It is possible people who have a shorter version of the ruthlessness gene (AVPR1a) may behave more selfishly.

Greed is an inordinate or insatiable longing for unneeded excess, especially for excess wealth, status, power, or food.

As secular psychological concept, greed is an inordinate desire to acquire or possess more than one needs. The degree of inordinance is related to the inability to control the reformulation of "wants" once desired "needs" are eliminated. Erich Fromm described greed as "a bottomless pit which exhausts the person in an endless effort to satisfy the need without ever reaching satisfaction." It is typically used to criticize those who seek excessive material wealth, although it may apply to the need to feel more excessively moral, social, or otherwise better than someone else.

The purpose for greed, and any actions associated with it, is possibly to deprive others of potential means (perhaps, of basic survival and comfort) or future opportunities accordingly, or to obstruct them therefrom, thus insidious and tyrannical or otherwise having negative connotation. Alternately, the purpose could be defense or counteraction from such dangerous, potential negotiation in matters of questionable agreeability. A consequence of greedy activity may be inability to sustain any of the costs or burdens associated with that which has been or is being accumulated, leading to a backfire or destruction, whether of self or more generally. So, the level of "inordinance" of greed pertains to the amount of vanity, malice or burden associated with it.

The diagnostic criteria for Dorian Gray syndrome are:

- Signs of dysmorphophobia

- Arrested development (inability to mature)

- Using at least two different medical-lifestyle products and services:

- Hair-growth restoration (e.g. finasteride)

- Antiadiposita to lose weight (e.g. orlistat)

- Anti-impotence drugs (e.g. sildenafil)

- Anti-depressant drugs (e.g. fluoxetine)

- Cosmetic dermatology (e.g. laser resurfacing)

- Cosmetic surgery (e.g. a face-lift, liposuction)

Foerster's syndrome is the name used by Arthur Koestler in his account of the compulsive punning first described by the German neurosurgeon Otfrid Foerster.

In 1929, Foerster was operating on a patient suffering from a tumor in the third ventricle – a small cavity deep down in the phylogenetically ancient regions of the midbrain, adjacent to structures intimately concerned with the arousal of emotions. When the surgeon began to manipulate the tumor, affecting those sensitive structures, the (conscious) patient burst into a manic flight of puns. He exhibited typical sound associations, and with every word of the operator broke into a flight of ideas. The sound of one word swiftly echoed in the sound of the next, and all of the words had something to do with knives and butchery. This gruesome humour, Koestler noted, all came "from a man tied face down to the operating table with his skull open".

Uniform fetishism is a sexual fetishism where an individual is sexually aroused by uniforms.

Erotomania is a type of delusional disorder where the affected person believes that another person is in love with him or her. This belief is usually applied to someone with higher status or a famous person, but can also be applied to a complete stranger. Erotomanic delusions often occur in patients with schizophrenia and other psychotic disorders, but can also occur during a manic episode in the context of bipolar I disorder. During an erotomanic delusion, the patient believes that a secret admirer is declaring his or her affection for the patient, often by special glances, signals, telepathy, or messages through the media. Usually the patient then returns the perceived affection by means of letters, phone calls, gifts, and visits to the unwitting recipient. Even though these advances are unexpected and often unwanted, any denial of affection by the object of this delusional love is dismissed by the patient as a ploy to conceal the forbidden love from the rest of the world.

Erotomania is also called de Clérambault's syndrome, after French psychiatrist Gaëtan Gatian de Clérambault (1872–1934), who published a comprehensive review paper on the subject ("Les Psychoses Passionnelles") in 1921. Erotomania should not be confused with obsessive love or obsession with unrequited love, neither of which involves delusion.

Yunnan sudden death syndrome is a label used to define unexplained cases of cardiac arrest, which afflicted significant numbers of rural villagers in Yunnan province, in southwest China. Cases occurred almost always during the midsummer rainy season (from June to August), at an altitude of . The cause turned out to be a mushroom now blamed for an estimated 400 deaths in the past three decades.

The mysterious fatalities were recorded for decades before researchers from the Chinese Center for Disease Control and Prevention isolated a significant factor common in every case: a tiny unknown mushroom which was unintentionally gathered and consumed during wild mushroom harvests in the region. Previously the syndrome was thought to be caused by Keshan disease, caused by the Coxsackie virus.

The mushroom, "Trogia venenata", is also known as 'Little White'. It has been determined that families collecting fungi to sell have been eating these Little White mushrooms as they have no commercial value. Three amino acids present in the mushrooms have been shown to be toxic. The mushrooms have also been shown to contain very high quantities of barium, and it may be that some of the deaths are simply from barium poisoning.

In the hours before death, about two-thirds of the victims had such symptoms as nausea, dizziness, heart palpitations, seizures and fatigue.

However, in December 2012 it was announced that Dr Xu Jianping (徐建平) has been collecting samples of "Trogia venenata" in Yunnan for the past three years, and his research now shows that barium levels in the wild mushroom are no higher than those of common foods such as poultry and fish. Nonetheless, it appears the mushroom will still likely play a role. Since publication of the widely circulated 2010 "Science" article, no instances of Yunnan sudden death syndrome have been reported.

Don Juanism or Don Juan syndrome is a non-clinical term for the desire, in a man, to have sex with many different female partners.

The name derives from the Don Juan of opera and fiction. The term satyriasis is sometimes used as a synonym for Don Juanism. The term has also been referred to as the male equivalent of nymphomania in women. These terms no longer apply with any accuracy as psychological or legal categories of psychological disorder.

The Dorian Gray syndrome arises from the concurring and overlapping clinical concepts of the narcissistic personality, dysmorphophobia, and paraphilia. Psychodynamically, the man afflicted with DGS presents an interplay among his narcissistic tendencies ("timeless beauty"), his arrested development (inability to psychologically mature), and his use of "medical lifestyle" products and services — hair restoration, drugs (for impotence, weight-loss, and mood modification), laser dermatology, and plastic surgery — in order to remain young.

Although the DGS patient displays diagnostic features of said mental disorders, the syndrome describes a common, underlying psychodynamics of mental illness, which is characterized by narcissistic defences against time-dependent maturation, expressed by actively seeking the timeless beauty of youth. The article "Das Dorian Gray syndrom" (2005) reported that approximately 3.0 per cent of the population of Germany present features of the Dorian Gray syndrome.

The core symptom of the disorder is that the sufferer holds an unshakable belief that another person is secretly in love with them. In some cases, the sufferer may believe several people at once are "secret admirers". The sufferer may also experience other types of delusions concurrently with erotomania, such as delusions of reference, wherein the perceived admirer secretly communicates his or her love by subtle methods such as body posture, arrangement of household objects, and other seemingly innocuous acts (or, if the person is a public figure, through clues in the media). Erotomanic delusions are typically found as the primary symptom of a delusional disorder or in the context of schizophrenia and may be treated with atypical antipsychotics.

Coturnism is an illness featuring muscle tenderness and rhabdomyolysis (muscle cell breakdown) after consuming quail (usually common quail, "Coturnix coturnix", from which the name derives) that have fed on poisonous plants.

According to the WHO, a probable case is

- a person with a fever, respiratory infection, and evidence of pneumonia or acute respiratory distress syndromeandtesting for MERS-CoV is unavailable or negative on a single inadequate specimenandthe person has a direct link with a confirmed case.

- A person with an acute febrile respiratory illness with clinical, radiological, or histopathological evidence of pulmonary parenchymal disease (e.g. pneumonia or acute respiratory distress Syndrome)and an inconclusive MERS-CoV laboratory test (that is, a positive screening test without confirmation)anda resident of or traveler to Middle Eastern countries where MERS-CoV virus is believed to be circulating in the 14 days before onset of illness.

- A person with an acute febrile respiratory illness of any severity andan inconclusive MERS-CoV laboratory test (that is, a positive screening test without confirmation) andthe person has a direct epidemiologic link with a confirmed MERS-CoV case.

MERS cases have been reported to have low white blood cell count, and in particular low lymphocytes.

For PCR testing, the WHO recommends obtaining samples from the lower respiratory tract via bronchoalveolar lavage (BAL), sputum sample or tracheal aspirate as these have the highest viral loads. There have also been studies utilizing upper respiratory sampling via nasopharyngeal swab.

Several highly sensitive, confirmatory real-time RT-PCR assays exist for rapid identification of MERS-CoV from patient-derived samples. These assays attempt to amplify upE (targets elements upstream of the E gene), open reading frame 1B (targets the ORF1b gene) and open reading frame 1A (targets the ORF1a gene). The WHO recommends the upE target for screening assays as it is highly sensitive. In addition, hemi-nested sequencing amplicons targeting RdRp (present in all coronaviruses) and nucleocapsid (N) gene (specific to MERS-CoV) fragments can be generated for confirmation via sequencing. Reports of potential polymorphisms in the N gene between isolates highlight the necessity for sequence-based characterization.

The WHO recommended testing algorithm is to start with an upE RT-PCR and if positive confirm with ORF 1A assay or RdRp or N gene sequence assay for confirmation. If both an upE and secondary assay are positive it is considered a confirmed case.

Protocols for biologically safe immunofluorescence assays (IFA) have also been developed; however, antibodies against betacoronaviruses are known to cross-react within the genus. This effectively limits their use to confirmatory applications. A more specific protein-microarray based assay has also been developed that did not show any cross-reactivity against population samples and serum known to be positive for other betacoronaviruses. Due to the limited validation done so far with serological assays, WHO guidance is that "cases where the testing laboratory has reported positive serological test results in the absence of PCR testing or sequencing, are considered probable cases of MERS-CoV infection, if they meet the other conditions of that case definition."

Intermetamorphosis is a delusional misidentification syndrome, related to agnosia. The main symptoms consist of patients believing that they can see others change into someone else in both external appearance and internal personality. The disorder is usually comorbid with neurological disorders or mental disorders.

An example from medical literature is a man who was diagnosed with Alzheimer's disease. After some time he mistook his wife for his deceased mother and later for his sister. As an explanation, he stated that he had never been married or that his wife had left him. Later he mistook his son for his brother and his daughter for another sister. Visual agnosia or prosopagnosia were not diagnosed, as the misidentification also took place during phone calls. On several occasions he mistook the hospital for the church he used to go to.

The disorder was first described in 1932 by P. Courbon and J. Tusques ("Illusions d'intermétamorphose et de la charme"), in the Journal: Annales Medico-Psychologiques issue 14, page 401-406.

Protein poisoning (also referred to colloquially as rabbit starvation, mal de caribou, or fat starvation) is a rare form of acute malnutrition thought to be caused by a complete absence of fat in the diet.

Excess protein is sometimes cited as the cause of this issue; when meat and fat are consumed in the correct ratio, such as that found in pemmican (which is 50% fat by volume), the diet is considered nutritionally complete and can support humans for months or more. Other stressors, such as severe cold or a dry environment, may intensify symptoms or decrease time to onset. Symptoms include diarrhea, headache, fatigue, low blood pressure, slow heart rate, and a vague discomfort and hunger (very similar to a food craving) that can be satisfied only by the consumption of fat.

Protein poisoning was first noted as a consequence of eating rabbit meat exclusively, hence the term, "rabbit starvation". Rabbit meat is very lean; commercial rabbit meat has 50–100 g dissectable fat per 2 kg (live weight). Based on a carcass yield of 60%, rabbit meat is around 8.3% fat while beef and pork are 32% fat and lamb 28%.

From case histories it is known that the toxin is stable as four-month-old pickled quail have been poisonous. Humans vary in their susceptibility; only one in four people who consumed quail soup containing the toxin fell ill. The toxin is apparently fat-soluble as potatoes fried in quail fat have proved poisonous.

Coniine from hemlock consumed by quail has been suggested as the cause, though quail resist eating hemlock. Hellebore has also been suggested as the source of the toxin. It has also been asserted that this evidence points to the seeds of the annual woundwort ("Stachys annua") being the causal agent. It has been suggested that "Galeopsis ladanum" seeds are not responsible.

"Sex reassignment therapy" (SRT) is an umbrella term for all medical treatments related to sex reassignment of both transgender and intersex people.

Individuals make different choices regarding sex reassignment therapy, which may include female-to-male or male-to-female hormone replacement therapy (HRT) to modify secondary sex characteristics, sex reassignment surgery (such as orchiectomy) to alter primary sex characteristics, chest surgery such as top surgery or breast augmentation, or, in the case of trans women, a trachea shave, facial feminization surgery or permanent hair removal.

To obtain sex reassignment therapy, transsexual people are generally required to undergo a psychological evaluation and receive a diagnosis of gender identity disorder in accordance with the Standards of Care (SOC) as published by the World Professional Association for Transgender Health. This assessment is usually accompanied by counseling on issues of adjustment to the desired gender role, effects and risks of medical treatments, and sometimes also by psychological therapy. The SOC are intended as guidelines, not inflexible rules, and are intended to ensure that clients are properly informed and in sound psychological health, and to discourage people from transitioning based on unrealistic expectations.

Transsexual people experience a gender identity that is inconsistent with, or not culturally associated with, their assigned sex, and desire to permanently transition to the gender with which they identify, usually seeking medical assistance (including hormone replacement therapy and other sex reassignment therapies) to help them align their body with their identified sex or gender.

"Transsexual" is generally considered a subset of "transgender", but some transsexual people reject the label of "transgender". A medical diagnosis of gender dysphoria can be made if a person expresses a desire to live and be accepted as a member of their identified sex, and if a person experiences impaired functioning or distress as a result of their gender identity.

Among the most common uniforms in uniform fetish are those of a police officer, prison officer, soldier, schoolgirl, nurse, French maid, waitress, cheerleader, and Playboy Bunny. Some people also regard nuns' habits or even aprons as uniforms. The uniforms may be genuine, realistic, or they may be sexualized through the use of a very short miniskirt, a very long hobble skirt or a corset, through the use of stockings, fishnet tights, or high heels, or by being made of leather or latex, according to preference. Sometimes uniforms are used according to what activity is being done. For example, someone may wear a nurse's uniform to administer an enema or a police uniform to handcuff and cage someone. Two people may dress as inmates for cell mate-on-cell mate activities in a prison setting or as a submissive to a third (prison guard) roleplayer. This may add a sense of authenticity to the game play. A stripper dressed as a police officer is a popular fixture at birthday and bachelor parties. The "officer" begins with a mock "arrest", often using handcuffs, of the guest of honor before going into a dance routine.

There is currently no known treatment for Aleutian virus. When evidence of ADV shows in a ferret, it is strongly recommended that a CEP (counterimmunoelectrophoresis) blood test or an IFA (immunoflourescent antibody) test be done. The CEP test is usually faster and less expensive than the IFA test, but the IFA test is more sensitive and can detect the disease in borderline cases.

Additionally modern methods such as Real-Time PCR allow for rapid and accurate detection as well as determination of the amount of viron present.

Prevention is best accomplished by stopping the spread of ADV. Any new ferret, or those who have been confirmed as serum positive for the virus should be perpetually isolated from other ferrets. All items that may have come into contact with the infected ferret should be cleaned with a 10% bleach solution.

This is a growing concern within mink producers as it is the most crucial infectious disease which affects farmed mink worldwide.

Given the lack of scientific data on the effects of high-protein diets, the US Food and Nutrition Board does not set a tolerable upper intake level nor upper acceptable macronutrient distribution range for protein.

SPS is diagnosed by evaluating clinical findings and excluding other conditions. There is no specific laboratory test that confirms its presence. Underdiagnosis and misdiagnosis are common.

The presence of antibodies against GAD is the best indication of the condition that can be detected by blood and cerebrospinal fluid (CSF) testing. Anti-GAD65 is found in about 80 percent of SPS patients. Anti-thyroid, anti-intrinsic factor, anti-nuclear, anti-RNP, and anti-gliadin are also often present in blood tests. Electromyography (EMG) demonstrates involuntary motor unit firing in SPS patients. EMG can confirm the diagnosis by noting spasms in distant muscles as a result of subnoxious stimulation of cutaneous or mixed nerves. Responsiveness to diazepam helps confirm that the patient is suffering from SPS, as this decreases stiffness and motor unit potential firing.

The same general criteria are used to diagnose paraneoplastic SPS as the normal form of the condition. Once SPS is diagnosed, poor response to conventional therapies and the presence of cancer indicate that it may be paraneoplastic. CT scans are indicated for SPS patients who respond poorly to therapy to determine if this is the case.

A variety of conditions have similar symptoms to SPS, including myelopathies, dystonias, spinocerebellar degenerations, primary lateral sclerosis, neuromyotonia, and some psychogenic disorders. Tetanus, neuroleptic malignant syndrome, malignant hyperpyrexia, chronic spinal interneuronitis, serotonin syndrome, Multiple sclerosis, Parkinson's disease, and Isaacs syndrome should also be excluded.

Patients' fears and phobias often incorrectly lead doctors to think their symptoms are psychogenic, and they are sometimes suspected of malingering. It takes an average of six years after the onset of symptoms before the disease is diagnosed.

Psychiatrist Carl Jung believed that Don Juanism was an unconscious desire of a man to seek his mother in every woman he encountered. However, he didn't see the trait as entirely negative; Jung felt that positive aspects of Don Juanism included heroism, perseverance and strength of will.

Jung argues that related to the mother-complex "are homosexuality and Don Juanism, and sometimes also impotence. In homosexuality, the son's entire heterosexuality is tied to the mother in an unconscious form; in Don Juanism, he unconsciously seeks his mother in every woman he meets...Because of the difference in sex, a son's mother-complex does not appear in pure form. This is the reason why in every masculine mother-complex, side by side with the mother archetype, a significant role is played by the image of the man's sexual counterpart, the anima."

One of Theodore Millon's five narcissist variations is the amorous narcissist which includes histrionic features. According to Millon, the Don Juan or Casanova of our times is erotic and exhibitionistic.
