    2. 2. ThoughtThought Thought generally refers to any mental or intellectual activity involving an individuals subjective consciousness.  Act of thinking Thought Thought underlies almost all human action and interactions, Understanding its physical and meta physical origins, process and effects has been a longstanding goal of many academic disciplines – biology, philosophy, psychology and sociology.
    3. 3. Types of thinkingTypes of thinking Thinking allows us to make sense of or model the world in different ways and to represent or interpret it in ways that are significant to us. Fantasy – escape from reality , short duration , to move the mind from poverty to riches. eg day dream Imaginative – creative, novel out puts , usually with a end in mind .Artists, Rationale / conceptual – scientist
    4. 4. Disorder of content of thinkingDisorder of content of thinking Content :The color of thought.What is the person ‘thinking’? DISORDER in content is interpreted with respect to the general assumptions about normality and abnormality, as it is most often done by an external observer.
    5. 5. From ‘delude’, derived from a Latin word which means to mock Presence of delusion A loss of touch with reality, = Psychosis Phenominologically/ subjectively indistinguishable form a true belief Definitions Types of Delusions The origin of Delusions Types of Primary Delusions The Content of Delusions
    6. 6. DEFINITIONSDEFINITIONS “A false unshakeable belief which arises from internal morbid processes. It is easily unrecognizable when it is out of keeping with the person’s educational and cultural background” -Max Hamilton False unshakeable belief Morbid origin Out of keeping with the cultural and social background
    7. 7. JasperJasper According to Jaspers -They are held with unusual conviction -They are not amenable to logic/external influences -The absurdity of their content is manifest to other people
    8. 8. ExampleExample A man believed that his wife was unfaithful to him because the fifth lamp- post along on the left was unlit. Here belief may be culturally acceptable or even true but clearly delusional because of evidence evinced for holding the belief.
    9. 9. OVERVALUED IDEASOVERVALUED IDEAS Thought which, because of associated feeling tone, takes precedence over all ideas and maintains this precedence permanently or for a long period of time. Overvalued ideas are deeply held personal convictions that are understandable when the patient's background is known. For example, if a patient has two family members who have just developed cancer then the patient may have the belief that cancer is an illness that is contagious.

    11. 11. According to Conrad….According to Conrad…. The 5 stages in the development of delusions: 1) Trema: Delusional mood representing a change in perception 2) Apophany: A search for, and finding of new meanings to psychological events 3) Anastrophy: Heightening of psychosis 4) Consolidation: Formation of a new world based on new meanings 5) Residuum: Remaining autistic deficit.
    12. 12. Primary DelusionPrimary Delusion -New meaning arises in connection with some other psychological event -Ultimately un-understandable -diagnostic of schizophrenia, -may occur in epileptic psychosis
    13. 13.

A new symbolic meaning is attached to percept, intuition, memory Delusional perception Sudden delusional idea Delusional mood Delusional memory
    14. 14. DELUSIONAL MOODDELUSIONAL MOOD Person has the knowledge that there is something going on around him which concerns him, but does not know what it is. DELUSIONAL PERCEPTIONDELUSIONAL PERCEPTION Delusional perception is the attribution of a new meaning usually in the sense of self reference,to a normally perceived object. Important feature of this symptom is its two- memberedness. memory + delusional significance Eg: person says that he is of royal descent because he remembers that the spoon he used as a boy had a crown on it
    15. 15. SUDDEN DELUSIONAL IDEASUDDEN DELUSIONAL IDEA Delusion appears fully formed in the person’s mind. Autochthonous delusion Eg: person says that he is of royal descent because when he was taken to a military parade as a little boy the king saluted him. (Delusion is contained within the memory and there is no two-memberedness.)
    16. 16. Primary Delusional experiences – reported more in acute schizophrenia Less common in chronic schizophrenia
    17. 17. Secondary DelusionSecondary Delusion Those that arise from some other morbid experience Can be understood from the person’s cultural/emotional background Often transient Can occur in Schizophrenia, other psychotic conditions NOT an overvalued idea
    18. 18. Understandable with respect to the mood state or after viewing psychiatric history and MSE Originates in response to: other psychopathology -  Mood  Cultural contents  Personality traits  Primary delusions  Hallucinations  Formal thought disorder SECONDARY DELUSIONSECONDARY DELUSION
    19. 19. Secondary DelusionSecondary Delusion  In schizophrenia once primary delusional experience have occurred they are commonly integrated into some sort of delusional system.  This Elaboration  Ie .The story a deluded person builds around the delusion ‘delusional work’. Where apparently logical consequences and inferences are made around the delusion.  Systematization & Non Systematized  There is one basic delusion. The rest of the delusional beliefs are related to that, being systematically built over it. Systematization is seen as more or less. The degree depends upon the retention of integrity in the deluded person.
    20. 20. ORIGIN OF DELUSION The ultimate alteration from normal : Reality Perception Pre-morbid personality Social constraints Superego Poor communication A key experience Impaired cognition + Impaired attribution Delusion! Adaptive New identity/ purpose Freedom and protection

    47. 47. SchneiderSchneider Five features of FTD: Derailment- slides on to a subsidiary Substitution- major thought substituted Omission- senseless omission Fusion- heterogeneous elements are interwoven Drivelling- disordered intermixture
    48. 48. SchneiderSchneider Features of healthy thinking Constancy : Persistence of completed thought Organization :Thoughts related to each other & do not blend with each other but separated in organized way. Continuity: Thoughts are arranged in order and are in continuum
    49. 49. Three objective thought disordersThree objective thought disorders Transitory thinking Drivelling thinking- muddled parts Desultory thinking- sudden ideas force their way
    50. 50. Transitory thinking : - Grammatical & syntactical structures are both disturbed. - Continuity is not loosened. - Intention itself is affected. Drivelling thinking - Pt has - a preliminary outline of a - - complicated thought but - - looses preliminary organization of the thought so that all the constituent parts get muddled together Desultory thinking : - Grammatically & syntactically correct - Sudden ideas force their way time to time - Each idea – simple & suitable thought.
    51. 51. Healthy FTD Schizophrenic Constancy Derailment Transitory Substitution Omission Organization Drivelling Drivelling Continuity Fusion Desultory  Scheider claims that individual with Schizo complained of 3 diff disorders of thinking that corresspond to these 3 features of normal / non disordered thinking
