Treatment including addressing the cause, such as improving the diet, treating diarrhea, or stopping an offending medication. People without a significant source of potassium loss and who show no symptoms of hypokalemia may not require treatment.

Mild hypokalemia (>3.0 meq/l) may be treated with oral potassium chloride supplements (Klor-Con, Sando-K, Slow-K). As this is often part of a poor nutritional intake, potassium-containing foods may be recommended, such as leafy green vegetables, avocados, tomatoes, coconut water, citrus fruits, oranges, or bananas. Both dietary and pharmaceutical supplements are used for people taking diuretic medications.

Severe hypokalemia (<3.0 meq/l) may require intravenous supplementation. Typically, a saline solution is used, with 20–40 meq/l KCl per liter over 3–4 hours. Giving IV potassium at faster rates (20–25 meq/hr) may predispose to ventricular tachycardias and requires intensive monitoring. A generally safe rate is 10 meq/hr. Even in severe hypokalemia, oral supplementation is preferred given its safety profile. Sustained-release formulations should be avoided in acute settings.

Difficult or resistant cases of hypokalemia may be amenable to a potassium-sparing diuretic, such as amiloride, triamterene, spironolactone, or eplerenone. Concomitant hypomagnesemia will inhibit potassium replacement, as magnesium is a cofactor for potassium uptake.

When replacing potassium intravenously, infusion by a central line is encouraged to avoid the frequent occurrence of a burning sensation at the site of a peripheral infusion, or the rare occurrence of damage to the vein. When peripheral infusions are necessary, the burning can be reduced by diluting the potassium in larger amounts of fluid, or mixing 3 ml of 1% lidocaine to each 10 meq of KCl per 50 ml of fluid. The practice of adding lidocaine, however, raises the likelihood of serious medical errors.

Treatments for autoimmune disease have traditionally been immunosuppressive, anti-inflammatory, or palliative. Managing inflammation is critical in autoimmune diseases. Non-immunological therapies, such as hormone replacement in Hashimoto's thyroiditis or Type 1 diabetes mellitus treat outcomes of the autoaggressive response, thus these are palliative treatments. Dietary manipulation limits the severity of celiac disease. Steroidal or NSAID treatment limits inflammatory symptoms of many diseases. IVIG is used for CIDP and GBS. Specific immunomodulatory therapies, such as the TNFα antagonists (e.g. etanercept), the B cell depleting agent rituximab, the anti-IL-6 receptor tocilizumab and the costimulation blocker abatacept have been shown to be useful in treating RA. Some of these immunotherapies may be associated with increased risk of adverse effects, such as susceptibility to infection.

Helminthic therapy is an experimental approach that involves inoculation of the patient with specific parasitic intestinal nematodes (helminths). There are currently two closely related treatments available, inoculation with either Necator americanus, commonly known as hookworms, or Trichuris Suis Ova, commonly known as Pig Whipworm Eggs.

T cell vaccination is also being explored as a possible future therapy for autoimmune disorders.

The recommended treatment of new-onset pulmonary tuberculosis, as of 2010, is six months of a combination of antibiotics containing rifampicin, isoniazid, pyrazinamide, and ethambutol for the first two months, and only rifampicin and isoniazid for the last four months. Where resistance to isoniazid is high, ethambutol may be added for the last four months as an alternative.

If tuberculosis recurs, testing to determine which antibiotics it is sensitive to is important before determining treatment. If multiple drug-resistant TB (MDR-TB) is detected, treatment with at least four effective antibiotics for 18 to 24 months is recommended.

The amount of potassium deficit can be calculated using the following formula:

Meanwhile, the daily body requirement of potassium is calculated by multiplying 1 mmol to body weight in kilogrammes. Adding potassium deficit and daily potassium requirement would give the total amount of potassium need to be corrected in mmol. Dividing mmol by 13.4 will give the potassium in grams.

The medications most frequently used are the selective serotonin reuptake inhibitors (SSRIs). Clomipramine, a medication belonging to the class of tricyclic antidepressants, appears to work as well as SSRIs but has a higher rate of side effects.

SSRIs are a second line treatment of adult obsessive compulsive disorder (OCD) with mild functional impairment and as first line treatment for those with moderate or severe impairment. In children, SSRIs can be considered as a second line therapy in those with moderate-to-severe impairment, with close monitoring for psychiatric adverse effects. SSRIs are efficacious in the treatment of OCD; people treated with SSRIs are about twice as likely to respond to treatment as those treated with placebo. Efficacy has been demonstrated both in short-term (6–24 weeks) treatment trials and in discontinuation trials with durations of 28–52 weeks.

In 2006, the National Institute of Clinical and Health Excellence (NICE) guidelines recommended antipsychotics for OCD that does not improve with SSRI treatment. For OCD the evidence for the atypical antipsychotic drugs risperidone and quetiapine is tentative with insufficient evidence for olanzapine. A 2014 review article found two studies that indicated that aripiprazole was "effective in the short-term" and found that "[t]here was a small effect-size for risperidone or anti-psychotics in general in the short-term"; however, the study authors found "no evidence for the effectiveness of quetiapine or olanzapine in comparison to placebo." While quetiapine may be useful when used in addition to an SSRI in treatment-resistant OCD, these drugs are often poorly tolerated, and have metabolic side effects that limit their use. None of the atypical antipsychotics appear to be useful when used alone. Another review reported that no evidence supports the use of first generation antipsychotics in OCD.

A guideline by the APA suggested that dextroamphetamine may be considered by itself after more well supported treatments have been tried.

Electroconvulsive therapy (ECT) has been found to have effectiveness in some severe and refractory cases.

Surgery may be used as a last resort in people who do not improve with other treatments. In this procedure, a surgical lesion is made in an area of the brain (the cingulate cortex). In one study, 30% of participants benefitted significantly from this procedure. Deep-brain stimulation and vagus nerve stimulation are possible surgical options that do not require destruction of brain tissue. In the United States, the Food and Drug Administration approved deep-brain stimulation for the treatment of OCD under a humanitarian device exemption requiring that the procedure be performed only in a hospital with specialist qualifications to do so.

In the United States, psychosurgery for OCD is a treatment of last resort and will not be performed until the person has failed several attempts at medication (at the full dosage) with augmentation, and many months of intensive cognitive–behavioral therapy with exposure and ritual/response prevention. Likewise, in the United Kingdom, psychosurgery cannot be performed unless a course of treatment from a suitably qualified cognitive–behavioral therapist has been carried out.

Stress-reduction strategies can be helpful to many stressed/anxious person. However, many anxious persons cannot concentrate enough to use such strategies effectively for acute relief. (Most stress-reduction techniques have their greatest utility as elements of a prevention plan that attempts to raise one's threshold to anxiety-provoking experiences.)

Because there is uncertainty in treating suspected factitious disorder imposed on self, some advocate that health care providers first explicitly rule out the possibility that the person has another early-stage disease. Then they may take a careful history and seek medical records to look for early deprivation, childhood abuse, or mental illness. If a person is at risk to themself, psychiatric hospitalization may be initiated.

Healthcare providers may consider working with mental health specialists to help treat the underlying mood or disorder as well as to avoid countertransference. Therapeutic and medical treatment may center on the underlying psychiatric disorder: a mood disorder, an anxiety disorder, or borderline personality disorder. The patient's prognosis depends upon the category under which the underlying disorder falls; depression and anxiety, for example, generally respond well to medication and/or cognitive behavioral therapy, whereas borderline personality disorder, like all personality disorders, is presumed to be pervasive and more stable over time, and thus offers a worse prognosis.

People affected may have multiple scars on their abdomen due to repeated "emergency" operations.

Psychiatric consultation: Exploration of memories of the traumatic event, relief of associated symptoms and counseling.

Anisocoria is a condition characterized by an unequal size of the eyes' pupils. Affecting 20% of the population, it can be an entirely harmless condition or a symptom of more serious medical problems.

Psychopathy has often been considered untreatable. Its unique characteristics makes it among the most of personality disorders, a class of mental illnesses that are already traditionally considered difficult to treat. People afflicted with psychopathy are generally unmotivated to seek treatment for their condition, and can be uncooperative in therapy. Attempts to treat psychopathy with the current tools available to psychiatry have been disappointing. Harris and Rice's "Handbook of Psychopathy" says that there is currently little evidence for a cure or effective treatment for psychopathy; as of yet, no pharmacological therapies are known to or have been trialed for alleviating the emotional, interpersonal and moral deficits of psychopathy, and patients with psychopathy who undergo psychotherapy might gain the skills to become more adept at the manipulation and deception of others and be more likely to commit crime. Some studies suggest that punishment and behavior modification techniques are ineffective at modifying the behavior of psychopathic individuals as they are insensitive to punishment or threat. These failures have led to a widely pessimistic view on its treatment prospects, a view that is exacerbated by the little research being done into this disorder compared to the efforts committed to other mental illnesses, which makes it more difficult to gain the understanding of this condition that is necessary to develop effective therapies.

Although the core character deficits of highly psychopathic individuals are likely to be highly incorrigible to the currently available treatment methods, the antisocial and criminal behavior associated with it may be more amenable to management, the management of which being the main aim of therapy programs in correctional settings. It has been suggested that the treatments that may be most likely to be effective at reducing overt antisocial and criminal behavior are those that focus on self-interest, emphasizing the tangible, material value of prosocial behavior, with interventions that develop skills to obtain what the patient wants out of life in prosocial rather than antisocial ways. To this end, various therapies have been tried with the aim of reducing the criminal activity of incarcerated offenders with psychopathy, with mixed success. As psychopathic individuals are insensitive to sanction, reward-based management, in which small privileges are granted in exchange for good behavior, has been suggested and used to manage their behavior in institutional settings.

Psychiatric medications may also alleviate co-occurring conditions sometimes associated with the disorder or with symptoms such as aggression or impulsivity, including antipsychotic, antidepressant or mood-stabilizing medications, although none have yet been approved by the FDA for this purpose. For example, a study found that the antipsychotic clozapine may be effective in reducing various behavioral dysfunctions in a sample of high-security hospital inpatients with antisocial personality disorder and psychopathic traits. However, research into the pharmacological treatment of psychopathy and the related condition antisocial personality disorder is minimal, with much of the knowledge in this area being extrapolations based on what is known about pharmacology in other mental disorders.

Anisocoria is a common condition, defined by a difference of 0.4 mm or more between the sizes of the pupils of the eyes.

Anisocoria has various causes:

- Physiological anisocoria: About 20% of normal people have a slight difference in pupil size which is known as physiological anisocoria. In this condition, the difference between pupils is usually less than 1 mm.

- Horner's syndrome

- Mechanical anisocoria: Occasionally previous trauma, eye surgery, or inflammation (uveitis, angle closure glaucoma) can lead to adhesions between the iris and the lens.

- Adie tonic pupil: Tonic pupil is usually an isolated benign entity, presenting in young women. It may be associated with loss of deep tendon reflex (Adie's syndrome). Tonic pupil is characterized by delayed dilation of iris especially after near stimulus, segmental iris constriction, and sensitivity of pupil to a weak solution of pilocarpine.

- Oculomotor nerve palsy: Ischemia, intracranial aneurysm, demyelinating diseases (e.g., multiple sclerosis), head trauma, and brain tumors are the most common causes of oculomotor nerve palsy in adults. In ischemic lesions of the oculomotor nerve, pupillary function is usually spared whereas in compressive lesions the pupil is involved.

- Pharmacological agents with anticholinergic or sympathomimetic properties will cause anisocoria, particularly if instilled in one eye. Some examples of pharmacological agents which may affect the pupils include pilocarpine, cocaine, tropicamide, MDMA, dextromethorphan, and ergolines. Alkaloids present in plants of the genera "Brugmansia" and "Datura", such as scopolamine, may also induce anisocoria.

Deaf-mute is a term which was used historically to identify a person who was either deaf using a sign language or both deaf and could not speak. The term continues to be used to refer to deaf people who cannot speak an oral language or have some degree of speaking ability, but choose not to speak because of the negative or unwanted attention atypical voices sometimes attract. Such people communicate using sign language. Some consider it to be a derogatory term if used outside its historical context; the preferred term today is simply "deaf".

Factitious disorder imposed on self, also known as Munchausen syndrome, is a factitious disorder wherein those affected feign disease, illness, or psychological trauma to draw attention, sympathy, or reassurance to themselves. Munchausen syndrome fits within the subclass of factitious disorder with predominantly physical signs and symptoms, but patients also have a history of recurrent hospitalization, travelling, and dramatic, extremely improbable tales of their past experiences. The condition derives its name from Baron Munchausen.

Factitious disorder imposed on self is related to factitious disorder imposed on another, which refers to the abuse of another person, typically a child, in order to seek attention or sympathy for the abuser. This drive to create symptoms for the victim can result in unnecessary and costly diagnostic or corrective procedures.

Factitious disorder imposed on another, also known as Munchausen syndrome by proxy (MSbP), is a condition where a caregiver or spouse fabricates, exaggerates, or induces mental or physical health problems in those who are in their care, with the primary motive of gaining attention or sympathy from others. The name is derived from the term Munchausen syndrome, a psychiatric factitious disorder wherein those affected feign disease, illness, or psychological trauma to draw attention, sympathy, or reassurance to themselves. However, unlike Munchausen syndrome, in MSbP, the deception involves not themselves, but rather someone under the person's care. MSbP is primarily distinguished from other forms of abuse or neglect by the motives of the perpetrator. Some experts consider it to be an elusive, potentially lethal, and frequently misunderstood form of child abuse or medical neglect. However, others consider the concept to be problematic, since it is based largely on supposition regarding a person's motives, which can be open to radically different interpretations.

Factitious disorder imposed on another has also spawned much heated controversy within the legal and social services communities. In a handful of high-profile cases, mothers who have had several children die from sudden infant death syndrome have been declared to have MSbP. Based on MSbP testimony of an expert witness, they were tried for murder, convicted, and imprisoned for several years. In some cases, that testimony was later impeached, resulting in exoneration of those defendants.

The PCL-R, the PCL:SV, and the PCL:YV are highly regarded and widely used in criminal justice settings, particularly in North America. They may be used for risk assessment and for assessing treatment potential and be used as part of the decisions regarding bail, sentence, which prison to use, parole, and regarding whether a youth should be tried as a juvenile or as an adult. There have been several criticisms against its use in legal settings. They include the general criticisms against the PCL-R, the availability of other risk assessment tools which may have advantages, and the excessive pessimism surrounding the prognosis and treatment possibilities of those who are diagnosed with psychopathy.

The interrater reliability of the PCL-R can be high when used carefully in research but tend to be poor in applied settings. In particular Factor 1 items are somewhat subjective. In sexually violent predator cases the PCL-R scores given by prosecution experts were consistently higher than those given by defense experts in one study. The scoring may also be influenced by other differences between raters. In one study it was estimated that of the PCL-R variance, about 45% was due to true offender differences, 20% was due to which side the rater testified for, and 30% was due to other rater differences.

To aid a criminal investigation, certain interrogation approaches may be used to exploit and leverage the personality traits of suspects thought to have psychopathy and make them more likely to divulge information.

In factitious disorder imposed on another, a caregiver makes a dependent person appear mentally or physically ill in order to gain attention. To perpetuate the medical relationship, the caregiver systematically misrepresents symptoms, fabricates signs, manipulates laboratory tests, or even purposely harms the dependent (e.g. by poisoning, suffocation, infection, physical injury). Studies have shown a mortality rate of between 6% and 10%, making it perhaps the most lethal form of abuse.

At the time of diagnosis, the average age of the persons affected was 4 years. Slightly over 50% were aged 24 months or younger, and 75% were under 6 years old. The average duration from onset of symptoms to diagnosis was 22 months. By the time of diagnosis, 6% of the affected persons were dead, mostly from apnea (a common result of smothering) or starvation, and 7% suffered long-term or permanent injury. About half of the affected had siblings; 25% of the known siblings were dead, and 61% of siblings had symptoms similar to the affected or that was otherwise suspicious. The mother was the perpetrator in 76.5% of the cases, the father in 6.7%.

Most present about 3 medical problems in some combination of the 103 different reported symptoms. The most frequently reported problems are apnea (26.8% of cases), anorexia / feeding problems (24.6% of cases), diarrhea (20%), seizures (17.5%), cyanosis (blue skin) (11.7%), behavior (10.4%), asthma (9.5%), allergy (9.3%), and fevers (8.6%). Other symptoms include failure to thrive, vomiting, bleeding, rash and infections. Many of these symptoms are easy to fake because they are subjective. A parent reporting that their child had a fever in the past 24 hours is making a claim that is impossible to prove or disprove. The number and variety of presented symptoms contribute to the difficulty in reaching a proper MSbP diagnosis.

Aside from the motive (which is to gain attention or sympathy), another feature that differentiates MSbP from "typical" physical child abuse is the degree of premeditation involved. Whereas most physical abuse entails lashing out at a child in response to some behavior (e.g., crying, bedwetting, spilling food), assaults on the MSbP victim tend to be unprovoked and planned.

Also unique to this form of abuse is the role that health care providers play by actively, albeit unintentionally, enabling the abuse. By reacting to the concerns and demands of perpetrators, medical professionals are manipulated into a partnership of child maltreatment. Challenging cases that defy simple medical explanations may prompt health care providers to pursue unusual or rare diagnoses, thus allocating, even more, time to the child and the abuser. Even without prompting, medical professionals may be easily seduced into prescribing diagnostic tests and therapies that are at best uncomfortable and costly, and at worst potentially injurious to the child. If the health practitioner instead resists ordering further tests, drugs, procedures, surgeries, or specialists, the MSbP abuser makes the medical system appear negligent for refusing to help a poor sick child and their selfless parent. Like those with Munchausen syndrome, MSbP perpetrators are known to switch medical providers frequently until they find one that is willing to meet their level of need; this practice is known as "doctor shopping" or "hospital hopping".

The perpetrator continues the abuse because maintaining the child in the role of patient satisfies the abuser's needs. The cure for the victim is to separate the child completely from the abuser. When parental visits are allowed, sometimes there is a disastrous outcome for the child. Even when the child is removed, the perpetrator may then abuse another child: a sibling or other child in the family.

Factitious disorder imposed on another can have many long-term emotional effects on a child. Depending on their experience of medical interventions, a percentage of children may learn that they are most likely to receive the positive maternal attention they crave when they are playing the sick role in front of health care providers. Several case reports describe Munchausen syndrome patients suspected of themselves having been MSbP victims. Seeking personal gratification through illness can thus become a lifelong and multi-generational disorder in some cases. In stark contrast, other reports suggest survivors of MSbP develop an avoidance of medical treatment with post-traumatic responses to it. This variation possibly reflects broad statistics on survivors of child abuse in general, where around 30% go on to also become abusers even though a significant percentage do not.

The adult care provider who has abused the child often seems comfortable and not upset over the child's hospitalization. While the child is hospitalized, medical professionals must monitor the caregiver's visits to prevent an attempt to worsen the child's condition. In addition, in many jurisdictions, medical professionals have a duty to report such abuse to legal authorities.

It is sometimes used to refer to other hearing people in jest, to chide, or to invoke an image of someone who refuses to employ common sense or who is unreliable. "Deaf and dumb", "semi-deaf" and "semi-mute" are other historic references to deaf people.

In the past "deaf-mute" was used to describe deaf people who used sign language, but in modern times, the term is frequently viewed as offensive and inaccurate. From antiquity (as noted in the Code of Hammurabi) until recent times, the terms "deaf-mute" and "deaf and dumb" were sometimes considered analogous to "stupid" by some hearing people.

The simple identity of "deaf" has been embraced by the community of signing deaf people since the foundations of public deaf education in the 18th century and remains the preferred term of reference or identity for many years. Within the deaf community there are some who prefer the term "Deaf" (upper-case D) to "deaf" (lower-case) as a description of their status and identity.

Classification as a deaf-mute has a particular importance in Jewish law. Because historically it was thought impossible to teach or communicate with them, deaf-mutes were not moral agents, and therefore were unable to own real estate, act as witnesses, or be punished for any crime. However, today when techniques for educating deaf people are known, they are no longer classed as such.
