Psychosomatic medicine is an interdisciplinary medical field exploring the relationships among social, psychological, behavioral factors on bodily processes and quality of life in humans and animals.
Factitious disorder imposed on self, also known as Munchausen syndrome, is a factitious disorder in which those affected feign or induce disease, illness, injury, abuse, 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 the fictional character Baron Munchausen.
Hysteria is a term used colloquially to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the nineteenth century, female hysteria was a commonly diagnosed physical illness in both men and women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the twentieth century, it shifted to being considered a mental illness. Many influential people such as Sigmund Freud and Jean-Martin Charcot dedicated research to hysteria patients.
Koro is a culture bound delusional disorder in which individuals have an overpowering belief that their sex organs are retracting and will disappear, despite the lack of any true longstanding changes to the genitals. Koro is also known as shrinking penis, and it is listed in the Diagnostic and Statistical Manual of Mental Disorders.
Tension myositis syndrome (TMS), also known as tension myoneural syndrome or mindbody syndrome, is a name given by John E. Sarno to a condition of psychogenic musculoskeletal and nerve symptoms, most notably back pain. Sarno described TMS in four books, and stated that the condition may be involved in other pain disorders as well. The treatment protocol for TMS includes education, writing about emotional issues, resumption of a normal lifestyle and, for some patients, support meetings and/or psychotherapy. In 2007, David Schechter published a peer-reviewed study of TMS treatment in the journal "Alternative Therapies in Health and Medicine," showing a 54% success rate for chronic back pain. In terms of statistical significance and success rate, the study outperformed similar studies of other psychological interventions for chronic back pain.
Conversion disorder (CD), or functional neurologic symptom disorder, is a diagnostic category used in some psychiatric classification systems. It is sometimes applied to patients who present with neurological symptoms, such as numbness, blindness, paralysis, or fits, which are not consistent with a well-established organic cause, which cause significant distress, and can be traced back to a psychological trigger. It is thought that these symptoms arise in response to stressful situations affecting a patient's mental health or an ongoing mental health condition such as depression. Conversion disorder was retained in DSM-5, but given the subtitle functional neurological symptom disorder. The new criteria cover the same range of symptoms, but remove the requirements for a psychological stressor to be present and for feigning to be disproved. ICD-10 classifies conversion disorder as a dissociative disorder while DSM-IV classifies it as a somatoform disorder.
Dhat syndrome is a condition found in the cultures of South Asia in which male patients report that they suffer from premature ejaculation or impotence, and believe that they are passing semen in their urine. The condition has no known organic cause.
False pregnancy is the appearance of clinical or subclinical signs and symptoms associated with pregnancy although the individual is not physically carrying a baby. The mistaken impression that one is pregnant includes signs and symptoms such as tender breasts with secretions, abdominal growth, delayed menstrual periods, and subjective feelings of a moving fetus. Examination, ultrasound, and pregnancy tests can be used to rule out false pregnancy.
Hwabyeong or Hwapyŏng 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. Hwabyeong is known as a Korean culture-bound syndrome. Hwabyeong is a colloquial name, and it refers to the etiology of the disorder rather than its symptoms or apparent characteristics. In one survey, 4.1% of the general population in a rural area in Korea were reported as having hwabyeong. Hwabyeong is similar to Amuk.
Female hysteria was once a common medical diagnosis for women, which was described as exhibiting a wide array of symptoms, including anxiety, shortness of breath, fainting, nervousness, sexual desire, insomnia, fluid retention, heaviness in the abdomen, irritability, loss of appetite for food or sex, (paradoxically) sexually forward behaviour, and a "tendency to cause trouble for others". It is no longer recognized by medical authorities as a medical disorder. Its diagnosis and treatment were routine for hundreds of years in Western Europe.
Grisi siknis is a contagious, culture-bound syndrome that occurs predominantly among the Miskito people of eastern Central America, and affects mainly young women. It is also known as "grisi munaia", "Chipil siknis", and "Nil siknis". More recently, cases occurring amongst people of Spanish descent have also been reported.
Rabies is a viral disease that causes encephalitis in humans and other mammals. It was historically referred to as hydrophobia due to the symptom of panic when presented with liquids to drink. Early symptoms can include fever and tingling at the site of exposure. These symptoms are followed by one or more of the following symptoms: nausea, vomiting, violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is virtually always death, regardless of treatment. The time period between contracting the disease and the start of symptoms is usually one to three months but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system.
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. While not painful, it can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat.
Frigophobia is a phobia pertaining to the fear of becoming too cold. Frigophobia is a condition that appears mainly in the Chinese culture. Sufferers of this problem bundle up in heavy clothes and blankets, regardless of the ambient air temperature. This disorder has been linked to other psychological disorders such as hypochondriasis and obsessive-compulsive disorder. In a 1975 study among ethnic Chinese in Taiwan, it was noted that frigophobia may be culturally linked to koro. Where that disorder causes male sufferers to feel that their penis is retracting into the body due to an insufficiency of "male element", male frigophobia sufferers correlate coldness with an over-abundance of "female element".
A somatic symptom disorder, formerly known as a somatoform disorder, is any mental disorder that manifests as physical symptoms that suggest illness or injury, but cannot be explained fully by a general medical condition or by the direct effect of a substance, and are not attributable to another mental disorder. Somatic symptom disorders, as a group, are included in a number of diagnostic schemes of mental illness, including the Diagnostic and Statistical Manual of Mental Disorders.
In the nineteenth and early twentieth century, hysteria was a common psychiatric diagnosis made primarily in women. The existence and nature of a purported male hysteria was a debated topic around the turn of the century. It was originally believed that men could not suffer from hysteria because of their lack of uterus. This belief was discarded in the 17th century when discourse identified the brain or mind, and not reproductive organs, as the root cause of hysteria. During World War I, hysterical men were diagnosed with shell shock or war neurosis, which later went on to shape modern theories on PTSD. The notion of male hysteria was initially connected to the post-traumatic disorder known as railway spine; later, it became associated with war neurosis.
In the folklore of the early United States, a madstone was a special medicinal substance that, when pressed into an animal bite, was believed to prevent rabies by drawing the "poison" out. The Encyclopedia Americana described it as "a vegetable substance or stone". Researchers publishing in 1958 reported "130 cases of healing attributed to the madstone" and "three authenticated stones in the United States today."
A functional neurologic disorder or functional neurological disorder (FND) is a condition in which patients experience neurological symptoms such as weakness, movement disorders, sensory symptoms and blackouts. Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease. The intended contrast is with an organic brain syndrome, where a physiological cause can be identified. Subsets of functional neurological disorders include functional neurological symptom disorder (FNsD), conversion disorder, and psychogenic movement disorder/non-epileptic seizures. The diagnosis is made based on positive signs and symptoms in the history and examination during consultation of a neurologist. Physiotherapy is particularly helpful for patients with motor symptoms and tailored cognitive behavioural therapy has the best evidence in patients with dissociative (non-epileptic) attacks.
