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.

There are also motor activity disturbances such as hyperactivity, spontaneous attacks, shouting, scattering objects, and disrupting individuals gathered in groups. Someone suffering from this disorder may not always appear to be in control of their body. The individual may fall down, bump into things inadvertently, and have difficulty making movements with arms and legs. It has been noted that loss of bowel and bladder control can also be present.

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".

Episodes of major depressive disorder and of suicidal crisis occur in the man afflicted with Dorian Gray syndrome when the defense mechanism activities, the pursuit of eternal youth, fail to indefinitely preserve his handsome face and sculpted physique; usually, anti-depressant drugs and psychotherapy are prescribed and applied to counter his feelings of failure.

Furthermore, if the man misunderstands the self-defensive character of "acting out" the DGS, and continues pursuing the timeless beauty of male youth, without being aware of the psychodynamics of narcissism, then he, as a psychiatric patient, establishes a cycle of chronic psychological depression. In extreme cases of DGS, the man seeks self-destruction, by means either of drugs or with plastic surgery, or both, in order to fill the narcissistic emptiness that is the Dorian Gray syndrome.

Currently there is no specific treatment for this condition. Management is supportive.

Several treatments have been tested for treating premature ejaculation. A combination of medication and non-medication treatments is often the most effective method.

Neither the combination of antivirals and interferons (ribavirin + interferon alfa-2a or interferon alfa-2b) nor corticosteroids improved outcomes.

When rhesus macaques were given interferon-α2b and ribavirin and exposed to MERS, they developed less pneumonia than control animals. Five critically ill people with MERS in Saudi Arabia with ARDS and on ventilators were given interferon-α2b and ribavirin but all ended up dying of the disease. The treatment was started late in their disease (a mean of 19 days after hospital admission) and they had already failed trials of steroids so it remains to be seen whether it may have benefit earlier in the course of disease. Another proposed therapy is inhibition of viral protease or kinase enzymes. Researchers are investigating a number of ways to combat the outbreak of Middle East respiratory syndrome coronavirus, including using interferon, chloroquine, chlorpromazine, loperamide, and lopinavir, as well as other agents such as mycophenolic acid and camostat.

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.

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

Drugs that increase serotonin signalling in the brain slow ejaculation and have been used successfully to treat PE. These include selective serotonin reuptake inhibitors (SSRIs), such as paroxetine or dapoxetine, as well as clomipramine. Ejaculatory delay typically begins within a week of beginning medication. The treatments increase the ejaculatory delay to 6–20 times greater than before medication. Men often report satisfaction with treatment by medication, and many discontinue it within a year. However, SSRIs can cause various types of sexual dysfunction such as anorgasmia, erectile dysfunction, and diminished libido.

Dapoxetine is a short-acting SSRI which appears to work when taken as needed for PE. It is generally well tolerated. Tramadol, an atypical oral analgesic, appears to be effective.

Desensitizing topical medications like lidocaine that are applied to the tip and shaft of the penis can also be used. These are applied "as needed", 10–15 minutes before sexual activity and have fewer potential systemic side effects as compared to pills. Use of topicals is sometimes disliked due to the reduction of sensation in the penis as well as for the partner (due to the medication rubbing onto the partner).

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.

There is no evidence-based criteria for treating SPS, and there have been no large controlled trials of treatments for the condition. The rarity of the disease complicates efforts to establish guidelines.

GABA agonists, usually diazepam but sometimes other benzodiazepines, are the primary treatment for SPS. Drugs that increase GABA activity alleviate muscle stiffness caused by a lack of GABAergic tone. They increase pathways that are dependent upon GABA and have muscle relaxant and anticonvulsant effects, often providing symptom relief. Because the condition worsens over time, patients generally require increased dosages, leading to more side effects. For this reason, gradual increase in dosage of benzodiazepines is indicated. Baclofen, a GABA agonist, is generally used when individuals taking high doses of benzodiazepines have high side effects. In some cases it has shown improvements in electrophysiological and muscle stiffness when administered intravenously. Intrathecal baclofen administration may not have long-term benefits though, and there are potential serious side effects.

Treatments that target the autoimmune response are also used. Intravenous immunoglobin is the best second-line treatment for SPS. It often decreases stiffness and improves quality of life and startle reflex. It is generally safe, but there are possible serious side effects and it is expensive. The European Federation of Neurological Societies suggests it be used when disabled patients do not respond well to diazepam and baclofen. Steroids, rituximab, and plasma exchange have been used to suppress the immune system in SPS patients, but the efficacy of these treatments is unclear. Botulinum toxin has been used to treat SPS, but it does not appear to have long-term benefits and has potential serious side effects. In paraneoplastic cases, tumors must be managed for the condition to be contained. Opiates are sometimes used to treat severe pain, but in some cases they exacerbate symptoms.

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.

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.

"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.

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.

Meditation has demonstrated effectiveness in case studies.

There is yet no reliable medication for delayed ejaculation. PDE5 inhibitors such as Viagra have little effect. In fact, Viagra has a delaying effect on ejaculation, possibly through additional effect in the brain or decrease of sensitivity in the head of the penis.

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.

For secondary erythromelalgia, treatment of the underlying primary disorder is the most primary method of treatment. Although aspirin has been thought to reduce symptoms of erythromelalgia, it is rare to find evidence that this is effective. Mechanical cooling of the limbs by elevating them can help or managing the ambient environment frequently is often necessary constantly as flares occur due to sympathetic autonomic dysfunction of the capillaries. The pain that accompanies it is severe and treated separately (the pain is similar to CRPS, phantom limb or thalamic pain syndrome). Patients are strongly advised "not" to place the affected limbs in cold water to relieve symptoms when flaring occurs. It may seem a good idea, but it precipitates problems further down the line causing damage to the skin and ulceration often intractable due to the damaged skin. A possible reduction in skin damage may be accomplished by enclosing the flaring limb in a commonly available, thin, heat transparent, water impermeable, plastic food storage bag. The advice of a physician is advised depending on specific circumstances.

Primary erythromelalgia management is symptomatic, i.e. treating painful symptoms only. Specific management tactics include avoidance of attack triggers such as: heat, change in temperature, exercise or over exertion, alcohol and spicy foods. This list is by no means comprehensive as there are many triggers to set off a 'flaring' episode that are inexplicable. Whilst a cool environment is helpful in keeping the symptoms in control, the use of cold water baths is strongly discouraged. In pursuit of added relief sufferers can inadvertently cause tissue damage or death, i.e. necrosis. See comments at the end of the preceding paragraph regarding possible effectiveness of plastic food storage bags to avoid/reduce negative effects of submersion in cold water baths.

One clinical study has demonstrated the efficacy of IV lidocaine or oral mexilitine, though it should be noted that differences between the primary and secondary forms were not studied. Another trial has shown promise for misoprostol, while other have shown that gabapentin, venlafaxine and oral magnesium may also be effective, but no further testing was carried out as newer research superseded this combination.

Strong anecdotal evidence from EM patients shows that a combination of drugs such as duloxetine and pregabalin is an effective way of reducing the stabbing pains and burning sensation symptoms of erythromelalgia in conjunction with the appropriate analgesia. In some cases, antihistamines may give some relief. Most people with erythromelalgia never go into remission and the symptoms are ever present at some level, whilst others get worse, or the EM is eventually a symptom of another disease such as systemic scleroderma.

Some suffering with EM are prescribed ketamine topical creams as a way of managing pain on a long term basis. Feedback from some EM patients has led to reduction in usage as they believe it is only effective for short periods.

Living with erythromelalgia can result in a deterioration in quality of life resulting in the inability to function in a work place, lack of mobility, depression, and is socially alienating; much greater education of medical practitioners is needed. As with many rare diseases, many people with EM end up taking years to get a diagnosis and to receive appropriate treatment.

Research into the genetic mutations continues but there is a paucity of clinical studies focusing on living with erythromelalgia. There is much urgency within pharmaceutical companies to provide a solution to those who suffer with pain such as that with erythromelalgia.

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%.

Currently, antibiotic drugs such as penicillin or tetracycline are the only effective methods for disease treatment. Within wild populations, disease control consists of reducing the amount of bacterial spores present in the environment. This can be done by removing contaminated carcasses and scat.

The drug tafamidis has completed a phase II/III 18-month-long placebo controlled clinical trial

and these results in combination with an 18-month follow-on study demonstrated that Tafamidis or Vyndaqel slowed progression of FAP, particularly when administered to patients early in the course of FAP. This drug is now approved by the European Medicines Agency.

The US Food and Drug Administration's Peripheral and Central Nervous System Drugs Advisory Committee rejected the drug in June 2012, in a 13-4 vote. The committee stated that there was not enough evidence supporting efficacy of the drug, and requested additional clinical trials.
