Glossary of psychiatry
In this Glossary of Psychiatric Terms, mostly Greek, secondly French and German and some English terms, as used in psychiatric literature, were defined.  We have included many other terms with the passage of time and  aim to broaden this article to include most of the psychopathological terms in use.
There are many psychiatric terms that are of foreign-language, mostly Greek, origin; and are thus not easily understood by many English speakers. Most of these terms refer to expressions dating from the early days of psychiatry in Europe. This glossary aims to make the meaning of these terms clearer.

# List of Terms

## Abreaction
Abreaction is an emotional release or discharge following recall of a painful experience. Used sometimes by police, forensics after administering amobarbital.

## Abulia
Aboulia or Abulia, in neurology, refers to a lack of will or initiative. The patient is unable to act or make decisions independently. It may range from subtle to overwhelming in severity.

## Achromatopsia

## Affect illusion
Illusions (Misperceptions) associated with and/or based on changes with mood for example at midnight a person may take a shadow as a ghost, but in the early part of night this may not be the case.

## Akataphasia
Akataphasia (Kraepelin 1896) refers to disorder  of thought expression in speech and results due to  dissolution of logical ordering of trains of thought.

## Akathisia
Is a feeling of 'inner restlessness' often brought on as a side effect of anti-psychotic medication. People with akathisia have a desire to keep moving and are unable to keep still even though their movements are voluntary (as opposed to other movement disorders such as tardive dyskinesia which is involuntary). It most often affects the legs. When mild it is usually worse at night.

## Alexithymia
The term was coined by Dr Peter Sifneos to describe a condition where the person is unable to put into words the emotions he feels.

## Alice in Wonderland Experience
In Alice in Wonderland Experience Subjects perceive objects (including animals and other humans, or parts of humans, animals, or objects) as appearing substantially smaller than in reality. Generally, the object appears far away or extremely close at the same time. Alternate term for this is somaesthetic aura. Also see #Lilliputian hallucinations

## Alliteration
Alliteration refers to the repetition of initial consonant sounds in neighbouring words. For example, "When I struck and slapped my humble horse, he began to run rapidly."

## Alogia
Literally, this term means "not having words". This refers to poverty of speech generally seen in chronic psychotic disorders such as schizophrenia. This may be seen in advanced dementia too.

## Amok
Amok, or mata galap: The term comes from Malaysia in its origin. The phrase "running amok" also comes from this syndrome. This is a rare culture bound syndrome in which the subject (known as a pengamok) suddenly withdraws from his peers and family and gets violent towards people around him and may also use whatever weapon available to him. He is very difficult to be stopped at that stage. Ultimately he falls into a sleep or stupor and when wakes up having little knowledge of his violent behaviour.

## Anhedonia
Anhedonia refers to a state of mind in which the subject finds no pleasure in anything. This is seen in severe depressive states and schizoid personality disorder.

## Anosognosia
Anosognosia is a phenomenon in which a patient usually suffering from stroke is unaware and indifferent towards his disability. #Hemiasomatognosia is a subtype of anosognosia in which the person suffering from hemiplegia neglects one half of his body.

## Anton's syndrome
Anton syndrome, occasionally known as Anton-Babinski syndrome, is a form of cortical blindness in which the patient denies the visual impairment. The patient may attempt to walk, bumping into objects and injuring himself.
Anton syndrome is caused by damaging the occipital lobes bilaterally or from disrupting the pathway from the primary visual cortex into the visual association cortex.

## Anwesenheit
Anwesenheit refers to the feeling of presence of something or some person. It can be seen in normal grief reaction, schizophrenia and some emotionally arousing situations.

## Apophanous perception
This is an alternate term for delusional perception. It is one of the Schneiderian first rank symptoms and is defined as a true perception, to which a patient attributes a false meaning. For example, a person may see written "No Trespassing" on a board and may infer from this that intelligence agencies are spying on him.

## Aphemia
Aphemia is the alternate term for mutism. Mutism is absence of speech with apparently normal level of consciousness. Mutism can be dissociative (hysterical) in which an individual (commonly a child or adolescent) stops speaking at once without involvement of any neurological or physical contributing factor; or it can be elective (selective) in which a child does not speak at all in certain situations (such as in school) but speaks well in other conditions (like at home or at play). A rare cause of mutism is akinetic mutism which results due to a lesion around 3rd ventricle of brain.

## Apperception
Apperception is a normal phenomenon and refers to the ability to understand sensory inputs in their context, to interpret them and to incorporate them into experience. Failure of apperception is seen in delirious states.

## Astasia-abasia
Astasia abasia is a form of psychogenic gait disturbance in which gait becomes impaired in the absence of any neurological or physical pathology. The person usually walks in a bizarre manner. He staggers and appears as if going to fall but always manages to catch hold of something in time. Sometimes these people cannot even stand but on the other hand they are well able to move their legs while lying down or sitting. Often associated with conversion disorder or somatization disorder.

## Asyndesis
Alternate term for Loosening of association. A milder form of derailment of thought, in which a person goes on jumping  from one topic to another and there is little connection among the topics. This is in contrast to flight of ideas where a person jumps from one topic to another and there is a connection among the topics.
See also #Entgleisen term introduced by (Cameron).

## Autistic thinking
Autistic thinking  is a term used to refer to thinking not in accordance with the facts of reality and emphasizes preoccupation with inner experience. See also #Dereistic thinking.

## Autokabalesis
An uncommonly used term used for suicide committed by jumping from a very high place.

## Automatic obedience
Automatic obedience is an exaggerated co-operation with an examiner's request, as if the patient were an 'automaton' robotically obeying a command. It is usually a sign of catatonia.

## Automatism
Automatisms are sequences of activity that occur without conscious control. They may be simple and repetitive (tic-like) or complex, and are usually natural-looking but purposeless; for example, repeatedly going through the motions of buttering a piece of bread when there is no bread there. Automatic behaviour is not usually recalled afterwards.

## Autoscopy
Autoscopy is the reduplicative hallucination of "seeing one's own body at a distance" and the person sees it from the place where he or she is located. Autoscopy is sometimes used synonymously with out of body experience.

## Belle Indifference (La belle indifference)

## Bouffee delirante
Bouffee delirante is a French term used in the past for acute and transient psychotic disorders (F23 in ICD-10). In DSM-IV, it is described as "Brief Psychotic Disorder" (298.8). The symptoms usually have an acute onset and reach their peak within two weeks. The symptoms start resolving in a few weeks and complete recovery usually occurs within 2-3 months.

## Brain Fag
Brain fag is an example of a culture-bound syndrome. Once a common term for mental exhaustion, it is now encountered almost exclusively in West Africa. Seen predominantly in male students, it generally manifests as vague somatic symptoms, depression, and difficulty concentrating. Read the article   for details.

## Capgras' syndrome or Illusion des sosies
In Capgras syndrome, the patient feels that  a person familiar to him, usually a family member has been replaced by a double i.e. an identical looking imposter. Capgras Syndrome and Fregoli syndrome along with some other conditions are classified as delusional misidentification syndrome.
It is named after Joseph Capgras (1873-1950), a French psychiatrist who first described the disorder in a paper by Capgras and Reboul-Lachaux1,2 in 1923. They used the term l'illusion des sosies (the illusion of doubles) to describe the case of a French woman who complained that various doubles had taken the place of people she knew. However, the term illusion has a subtly different meaning from delusion in psychiatry so Capgras delusion is used as a more suitable name.

## Catalepsy
Catalepsy is the term for catatonic rigidity of the limbs which often results in abnormal posturing for long intervals.

## Cataplexy
Cataplexy is an attack of muscular flaccidity especially in response to extreme emotional stimuli. It has to be differentiated from  syncope  where consciousness is lost and heart rate goes slow.

This occurs in catatonic schizophrenia, and a person suffering from this condition can have his limbs placed in fixed positions as if the person were in fact made from wax.

## Chorea
Chorea is manifest by abnormal voluntary movements. The term comes from Greek word choreia, since large groups of muscles are usually involved which leads to writhing dancing movement.

## Circumstantiality
Refers to a thought disorder wherein thinking takes a roundabout manner to get to an answer.  Differentiable from tangentiality by the speaker eventually getting back to the point.  For example: "My mother's job? She used to sit around the house doing nothing but drinking, she'd just sit there and stew, making noises, chugging her drinks.  She threw my dad out of the house.  I'll never forget that, the way she did it. Anyways, my mom was a waitress."

## Clang association
Thought disorder wherein words are chosen or repeated based on similar sounds, instead of semantic meaning.  "The train rain brained me.  He ate the skate, inflated yesterdays gate toward the cheese grater."

## Claparede's paradox
This refers to retention of non-verbal and implicit memory in sufferers of Korsakov's syndrome. 11

## Clouding of consciousness
Clouding of consciousness is a global impairment in higher central nervous functioning. All aspects of cognitive functioning are affected. On mental status examination it is manifest by disorientation in time, place and person, memory difficulties caused by failure to register and recall, aphasia, dyspraxia, and agnosia. Impaired perception functioning leads to illusions and hallucinations often in the visual sensory modality. This then causes agitation and distress and secondary delusions. The term 'confusion state' is sometimes used to mean clouding of consciousness, but should be avoided if at all possible because it is ambiguous.

## Coenestopathic state

## Dementia praecox
Psychiatrist Emil Kraepelin was the first to draw a distinction between what he termed dementia praecox ("premature dementia") and other psychotic illnesses. In 1911, dementia praecox was renamed schizophrenia by psychiatrist Eugen Bleuler, who found Kraepelin's term to be misleading, as the disorder is not a form of dementia, premature or otherwise.

## Dementia pugilistica
Dementia pugilistica, also called "chronic traumatic encephalopathy", "pugilistic Parkinson's syndrome", "boxer's syndrome", and "punch-drunk syndrome", is a neurological disorder which affects career boxers and others who receive multiple dazing blows to the head.

## Dereistic thinking
Dereistic thinking  is an old descriptive term used to refer to thinking not in accordance with the facts of reality and experience and following illogical, idiosyncratic reasoning.

## Folie a deux
Also called induced psychosis, folie a deux is a delusional disorder shared by two or more people who are closely related emotionally. One has real psychosis while the symptoms of psychosis are induced in the other or others due to close attachment to the one with psychosis. Separation usually results in symptomatic improvement in the one who is not psychotic.
Folie communiquee,  folie imposee, folie induite, and folie simultanee are the four subtypes of folie a deux.

### Folie communiquee
Folie communiquee, or subtype C of folie a deux, occurs when a normal person suffers a contagion of his ideas after resisting them for a long time. Once he acquires these beliefs he maintains them despite separation.

### Folie imposee
Folie imposee, or subtype A of folie a deux, is the most common form in which the dominant person imposes a delusion into a person who was not previously mentally ill. Separation of the two results in improvement of the non-dominant person.

### Folie induite
In folie induite, or subtype D of folie a deux, a person who is already psychotic adds the delusions of a closely associated person to his own.

### Folie simultanee
In folie simultanee, or subtype B of folie a deux, a delusional system emerges simultaneously and independently in two closely related persons, and the separation of the two would not be beneficial in the resolution of psychopathology.

## Fregoli's syndrome
In Fregoli syndrome,  the  person  feels  that a person not known to him previously gets changed to a familiar person or one of his close family members. This is in contrast to Capgras syndrome in which he feels that his family member has changed into an unknown person or an impostor.

## Gedankenlautwerden

## Zoofagus
Zoofagus is a ficticious condition that was diagnosed by Dr. John Seward in Bram Stoker's novel, Dracula. Renfield, the mentally insane character who is diagnosed with the illness, is said to collect small animals at first, such as flies. Then, the flies attract spiders, and the spiders attract sparrows (the pattern is in a food chain, and each of the next largest animal eats the last of the smallest). In theory, it appears that Renfield desires to get the largest animal possible (perhaps even a human) so that he may eat it himself and collect all of the "life force" that the animal had consumed before him. After Dr. Seward's observations, he gives the proper title "zoofagus" to Renfield. Dr. Seward explains that this term that he created literally means "life eater".
