Capgras Delusion
Capgras delusion or Capgras syndrome is a psychiatric disorder in which a person holds a delusion that a friend, spouse, parent, other close family member, or pet has been replaced by an identical impostor. It is named after Joseph Capgras (1873–1950), the French psychiatrist who first described the disorder. The Capgras delusion is classified as a delusional misidentification syndrome, a class of beliefs that involves the misidentification of people, places, or objects. It can occur in acute (medical), acute, transient state, transient, or chronic (medicine), chronic forms. Cases in which patients hold the belief that time has been "warped" or "substituted" have also been reported. The delusion most commonly occurs in individuals diagnosed with a Psychosis, psychotic disorder, usually schizophrenia; it has also been seen in Acquired brain injury, brain injury, dementia with Lewy bodies, and other forms of dementia. It presents often in individuals with a neurodegenerative dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental disorder, mental conditions. These include matters related to cognition, perceptions, Mood (psychology), mood, emotion, and behavior. Initial psychiatric assessment of a person begins with creating a Medical history, case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological tests may be conducted. On occasion, neuroimaging or neurophysiological studies are performed. Mental disorders are diagnosed in accordance with diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited by the World Health Organization (WHO), and the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013. Treatment may include psychotropics (psychiatric medicines), psychotherapy, su ...

Chronic (medicine)
A chronic condition (also known as chronic disease or chronic illness) is a health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that comes with time. The term ''chronic'' is often applied when the course of the disease lasts for more than three months. Common chronic diseases include diabetes, functional gastrointestinal disorder, eczema, arthritis, asthma, chronic obstructive pulmonary disease, autoimmune diseases, genetic disorders and some viral diseases such as hepatitis C and acquired immunodeficiency syndrome. An illness which is lifelong because it ends in death is a terminal illness. It is possible and not unexpected for an illness to change in definition from terminal to chronic as medicine progresses. Diabetes and HIV for example were once terminal yet are now considered chronic, due to the availability of insulin for diabetics and daily drug treatment for individuals with HIV, which allow these individuals to ...

Delusional Misidentification Syndrome
Delusional misidentification syndrome is an umbrella term, introduced by Christodoulou (in his book ''The Delusional Misidentification Syndromes'', Karger, Basel, 1986) for a group of four delusional disorders that occur in the context of mental illness, mental and neurological illness. They are grouped together as they often occur simultaneously or interchange, and they display the common concept of the Doppelgänger, double (sosie). They all involve a belief that the identity of a person, object, or place has somehow changed or has been altered. Christodoulu further categorized these disorders into those including hypo (or under)-identification of a well-known person (Capgras delusion), and hyper (or over)-identification of an unknown person (the remaining three). As these delusions typically only concern one particular topic, they also fall under the category called monothematic delusions. Variants This psychopathological syndrome is usually considered to include four main var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychoanalysis
PsychoanalysisFrom Greek language, Greek: and is a set of theories and techniques of research to discover unconscious mind, unconscious processes and their influence on conscious mind, conscious thought, emotion and behaviour. Based on The Interpretation of Dreams, dream interpretation, psychoanalysis is also a talk therapy method for treating of mental disorders."All psychoanalytic theories include the idea that unconscious thoughts and feelings are central in mental functioning." Milton, Jane, Caroline Polmear, and Julia Fabricius. 2011. ''A Short Introduction to Psychoanalysis''. Sage Group, SAGE. p. 27."What is psychoanalysis? Of course, one is supposed to answer that it is many things — a theory, a research method, a therapy, a body of knowledge. In what might be considered an unfortunately abbreviated description, Freud said that anyone who recognizes transference and resistance is a psychoanalyst, even if he comes to conclusions other than his own. … I prefer to think ...

Female Hysteria
Female hysteria was once a common medical diagnosis for women. It was described as exhibiting a wide array of symptoms, including anxiety, shortness of breath, fainting, nervousness, exaggerated and impulsive sexual desire, insomnia, fluid retention, heaviness in the abdomen, irritability, loss of appetite for food or sex, sexually impulsive behavior, 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. In extreme cases, the woman may have been forced to enter an insane asylum or to undergo surgical hysterectomy. In Western medicine, hysteria was considered both common and chronic among women. Though it was categorized as a disease at the time, modern day analyses suggest that hysteria's symptoms can be explained by the normal fluctuations of women's sexuality. Early history The history of hysteria diagnoses can be traced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ketamine
Ketamine is a cyclohexanone-derived general anesthetic and NMDA receptor antagonist with analgesic and hallucinogenic properties, used medically for anesthesia, depression, and pain management. Ketamine exists as its S- (esketamine) and R- (arketamine) two enantiomers and has antidepressant action likely involving additional mechanisms than NMDA antagonism. At anesthetic doses, ketamine induces a state of dissociative anesthesia, a trance-like state providing pain relief, sedation, and amnesia. Its distinguishing features as an anesthestic are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. As an anesthetic, it is used especially in trauma, Emergency medical services, emergency, and Pediatrics, pediatric cases. At lower, sub-anesthetic doses, it is used as a treatment for pain and treatment-resistant depression. Ketamine is legally used in medicine but is also tightly controlled due to ...

Migraine
Migraine (, ) is a complex neurological disorder characterized by episodes of moderate-to-severe headache, most often unilateral and generally associated with nausea, and light and sound sensitivity. Other characterizing symptoms may include vomiting, cognitive dysfunction, allodynia, and dizziness. Exacerbation or worsening of headache symptoms during physical activity is another distinguishing feature. Up to one-third of people with migraine experience aura, a premonitory period of sensory disturbance widely accepted to be caused by cortical spreading depression at the onset of a migraine attack. Although primarily considered to be a headache disorder, migraine is highly heterogenous in its clinical presentation and is better thought of as a spectrum disease rather than a distinct clinical entity. Disease burden can range from episodic discrete attacks to chronic disease. Migraine is believed to be caused by a mixture of environmental and genetic factors that influe ...

Hypothyroidism
Hypothyroidism is an endocrine disease in which the thyroid gland does not produce enough thyroid hormones. It can cause a number of symptoms, such as cold intolerance, poor ability to tolerate cold, fatigue, extreme fatigue, muscle aches, constipation, slow heart rate, Depression (mood), depression, and weight gain. Occasionally there may be swelling of the front part of the neck due to goiter. Untreated cases of hypothyroidism during pregnancy can lead to delays in child development, growth and intellectual development in the baby or congenital iodine deficiency syndrome. Worldwide, iodine deficiency, too little iodine in the diet is the most common cause of hypothyroidism. Hashimoto's thyroiditis, an autoimmune disease where the body's immune system reacts to the thyroid gland, is the most common cause of hypothyroidism in countries with sufficient dietary iodine. Less common causes include previous treatment with iodine-131, radioactive iodine, injury to the hypothalamus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diabetes
Diabetes mellitus, commonly known as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. Diabetes is due to either the pancreas not producing enough of the hormone insulin, or the cells of the body becoming unresponsive to insulin's effects. Classic symptoms include polydipsia (excessive thirst), polyuria (excessive urination), polyphagia (excessive hunger), weight loss, and blurred vision. If left untreated, the disease can lead to various health complications, including disorders of the cardiovascular system, eye, kidney, and nerves. Diabetes accounts for approximately 4.2 million deaths every year, with an estimated 1.5 million caused by either untreated or poorly treated diabetes. The major types of diabetes are type 1 and type 2. The most common treatment for type 1 is insulin replacement therapy (insulin injections), while anti-diabetic medications (such as metformin and semaglutide) and lifestyle modificatio ...

Neurodegenerative Disease
A neurodegenerative disease is caused by the progressive loss of neurons, in the process known as neurodegeneration. Neuronal damage may also ultimately result in their death. Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, tauopathies, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. Because there is no known way to reverse the progressive degeneration of neurons, these diseases are considered to be incurable; however research has shown that the two major contributing factors to neurodegeneration are oxidative stress and inflammation. Biomedical research has revealed many similarities between these diseases at the subcellular level, including atypical protein assemblies (like proteinopathy) and induced cell death. These similarities suggest that therap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dementia
Dementia is a syndrome associated with many neurodegenerative diseases, characterized by a general decline in cognitive abilities that affects a person's ability to perform activities of daily living, everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a thought disorder, disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum (measurement), continuum over several stages. Dementia is a life-limiting condition, having a significant effect on the individual, their caregivers, and their social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process.
