Psychiatry similarities to ti symptoms

• Leon Festinger

  Leon Festinger (8 May 1919 – 11 February 1989) was an American social psychologist who originated the theory of cognitive dissonance and social comparison theory. The rejection of the previously dominant behaviorist view of social psychology by demonstrating the inadequacy of stimulus-response conditioning accounts of human behavior is largely attributed to his theories and research.[1] Festinger is also credited with advancing the use of laboratory experimentation in social psychology,[2] although he simultaneously stressed the importance of studying real-life situations,[3] a principle he practiced when personally infiltrating a doomsday cult. He is also known in social network theory for the proximity effect (or propinquity).[4]

• New maps reveal the individual brain changes linked to different mental illness: Mapping brain changes in nearly 1,300 people different types of mental illness reveals diversity across conditions

  A breakthrough project mapping brain changes in nearly 1,300 people diagnosed with six different types of mental illness has revealed the extraordinary diversity of brain changes found in people with conditions like major depression and schizophrenia. The study used brain imaging to measure the size, or volume, of over 1000 different brain regions.

• Location of strong sense of discomfort in brain found

  Researchers have identified a new neural circuit in the brain which produces a strong sense of discomfort when activated. The discovery also allows them to show for the first time that the subthalamic nucleus, a structure in the brain that controls voluntary movements, may also play a role in the development of depression. The results could lead to better treatments for Parkinson's disease.

• The Neurobiology Shaping Affective Touch: Expectation, Motivation, and Meaning in the Multisensory Context

  Inter-individual touch can be a desirable reward that can both relieve negative affect and evoke strong feelings of pleasure. However, if other sensory cues indicate it is undesirable to interact with the toucher, the affective experience of the same ...

• Delusion

  A delusion is a false fixed belief that is not amenable to change in light of conflicting evidence.[1] As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs are able to change or readjust their beliefs upon reviewing the evidence. However:

• Thought withdrawal

  In psychiatry, thought withdrawal is the delusional belief that thoughts have been 'taken out' of the patient's mind, and the patient has no power over this.[1] It often accompanies thought blocking. The patient may experience a break in the flow of their thoughts, believing that the missing thoughts have been withdrawn from their mind by some outside agency. This delusion is one of Schneider's first rank symptoms for schizophrenia. Because thought withdrawal is characterized as a delusion, according to the DSM-IV TR it represents a positive symptom of schizophrenia.[2]

• Thought broadcasting

  Thought broadcasting is a type of delusional condition in which the affected person believes that others can hear their inner thoughts, despite a clear lack of evidence. The person may believe that either those nearby can perceive their thoughts or that they are being transmitted via mediums such as television, radio or the internet. Different people can experience thought broadcasting in different ways. Thought broadcasting is most commonly found among people that have a psychotic disorder, specifically schizophrenia.

• Thought insertion

  Thought insertion is defined by the ICD-10 as the delusion that one's thoughts are not one's own, but rather belong to someone else and have been inserted into one's mind.[1][2][3][4] The person experiencing the thought insertion delusion will not necessarily know where the thought is coming from, but makes a distinction between their own thoughts and those inserted into their minds.[5] However, patients do not experience all thoughts as inserted; only certain ones, normally following a similar content or pattern.[1] A person with this delusional belief is convinced of the veracity of their beliefs and is unwilling to accept such diagnosis.[6]

• Anomalous experiences

  Anomalous experiences, such as so-called benign hallucinations, may occur in a person in a state of good mental and physical health, even in the apparent absence of a transient trigger factor such as fatigue, intoxication or sensory deprivation.[1]

• Third man factor

  The third man factor or third man syndrome refers to the reported situations where an unseen presence, such as a spirit, provides comfort or support during traumatic experiences.

• Magnetophosphene

  Magnetophosphenes are flashes of light (phosphenes) that are seen when one is subjected to a changing magnetic field such as when in an MRI. This changing field causes current within the retina or visual cortex resulting in the illusion of light.[1] In one series, 8 out of 1023 people having an MRI experienced flashing lights.[2]

• Cenesthopathy

  Cenesthopathy (from French: cénestopathie,[1] formed from the Ancient Greek κοινός (koinós) "common", αἴσθησῐς (aísthēsis) "feeling", "perception" + πᾰ́θος (páthos) "feeling, suffering, condition"), also known as coenesthesiopathy,[2] is a rare psychiatric term used to refer to the feeling of being ill and this feeling is not localized to one region of the body.[3] Most notably, cenesthopathies are characterized by aberrant and strange bodily sensations (for example, a feeling of wires or coils being present within the oral region; tightening, burning, pressure, tickling etc. occurring in various parts of the body, and so on).[4]

• Tactile hallucination

  Tactile hallucination is the false perception of tactile sensory input that creates a hallucinatory sensation of physical contact with an imaginary object.[1] It is caused by the faulty integration of the tactile sensory neural signals generated in the spinal cord and the thalamus and sent to the primary somatosensory cortex (SI) and secondary somatosensory cortex (SII).[2] Tactile hallucinations are recurrent symptoms of neurological diseases such as schizophrenia, Parkinson's disease, Ekbom's syndrome and delirum tremens. Patients who experience phantom limb pains also experience a type of tactile hallucination. Tactile hallucinations are also caused by drugs such as cocaine and alcohol.[1]

• Somatosensory system

  In physiology, the somatosensory system is the network of neural structures in the brain and body that produce the perception of touch (haptic perception), as well as temperature (thermoception), body position (proprioception), and pain.[1] It is a subset of the sensory nervous system, which also represents visual, auditory, olfactory, and gustatory stimuli.

• Cenesthopathy

  Cenesthopathy (from French: cénestopathie,[1] formed from the Ancient Greek κοινός (koinós) "common", αἴσθησῐς (aísthēsis) "feeling", "perception" + πᾰ́θος (páthos) "feeling, suffering, condition"), also known as coenesthesiopathy,[2] is a rare psychiatric term used to refer to the feeling of being ill and this feeling is not localized to one region of the body.[3] Most notably, cenesthopathies are characterized by aberrant and strange bodily sensations (for example, a feeling of wires or coils being present within the oral region; tightening, burning, pressure, tickling etc. occurring in various parts of the body, and so on).[4]

• On the Origin of the "Influencing Machine" in Schizophrenia

  "On the Origin of the 'Influencing Machine' in Schizophrenia" (German: Über die Entstehung des „Beeinflussungsapparates“ in der Schizo­phrenie) is an article written by Austrian psychoanalyst Victor Tausk. He read it to and discussed it with the Vienna Psychoanalytic Society in January 1918.[1] It was first published in 1919 in the German-language journal Internationale Zeitschrift für Psychoanalyse and, after translation into English by Dorian Feigenbaum, in The Psychoanalytic Quarterly in 1933.[1]
