Types (Matussek) – Verbal variety and perceptual variety
  1. Delusional atmosphere(Delusional mood) – Patient knows that something funny is going on aroud him which concerns him but he cannot tell what it is. Patient feels profoundly uncomfortable , perplexed and apprehensive. When a delusional perception or sudden delusional idea arises it becomes obvious and he accepts that with a feeling of relief
        4    Delusional memories


SECONDARY DELUSIONS (DELUSION LIKE IDEAS)
False belief is understandable as arising from some other morbid experience like because of the mood state
Systematization
One basic delusion
Remainder of the system is logically built on this error
 BELIEF
 Is something thought to be true because of observation or evidence. It can often be subjected to empirical testing or logic to derive facts, which tend to be objective and universally agreed


VALUE
Is something thought to be good or important to an individual. Hence strongly held values are the principles on which one will not yield and are not subject to empirical testing

OVERVALUED IDEAS
A thought that because of its associated feeling tone takes precedence over all other ideas & maintains this precedence permanently or for long period of time.

OBSESSION
Recurrent intrusive ideas ,impulses,urges,thoughts, which enter into conscious awareness of individual inspite of efforts to resist it & recognize it as his own which is excessive & unreasonable with efforts to resist it leading to anxiety
An obsession) is a thought that persists and dominates an individual’s thinking despite the individual’s awareness that the thought is either entirely without purpose or else has persisted and dominated their thinking beyond the point of relevance or usefulness.

THINKING
Is a goal directed flow of ideas ,symbols,& associations initiated by a problem /task, characterized by a rational  connection between successive ideas /thoughts & leading towards a reality oriented conclusion  (AHUJA)
THINKING
 1) Undirected fantasy thinking: ‘autistic’ or ‘dereistic’ thinking.
 2) Imaginative thinking: This does not go beyond the rational and the

LOOSENNING OF-ASSOCIATION
 Often thinking stops in the middle of a thought instead of continuing the thought, new ideas crop up which neither the patient nor the observer can bring into any connection with the previous stream of thought

3 features of healthy thinking:
 1) Constancy: the characteristic persistence of a completed thought whether or not it is simple or complicated in its content.
2) Organization: the contents of the thoughts are related to each other in consciousness and do not blend with each other, but are separated in an organized way.
 3) Continuity: even the most heterogeneous thoughts, sudden ideas or observations which emerge are arranged in order in the whole content of the consciousness.

FLIGHT OF IDEAS
quick succession of ideas
There is no general direction of thinking.
connection btwn thoughts is by chance
diverted easily to external stimuli& internal superficial associations
verbal &clang associations
Clang associations are linked by the sound of the words more than their meaning

PROLIXITY
Ordered flight,despite several irrelevances pt returns to the task in hand.verbal & clang associations not so prominent ,thought emergence not very fast
CIRCUMSTANTIALITY:
 Thinking proceeds slowly with many unnecessary trivial details but finally the point is reached. The goal of thought is never completely lost and thinking proceeds towards it by an intricate and devious path

3) A distortion of another word.
4) An ordinary word used in a special way.

        MANNERISMS (BIZARRIES):
      “Unusual repeated performances of a goal-directed motor action or the maintenance of an unusual modification of an adaptive posture”.
        STEREOTYPIES: 
       Repetitive non-goal directed actions carried out in a uniform way

        PERSEVERATION:
      Is a senseless repetition of a goal-directed action/Speech which has already served its purpose beyond relevance
    . Compulsive repetition: the act is repeated unless the pt. receives another instruction – is more frequent in schizophrenics
       Impairment of switching: the repetition continues after the pt. has been given a new task – more common among dements.
   § Ideational perseveration: the pt. repeats words and phrases during his reply to a question – equally common in both groups.
         Palilalia: the pt. repeats the perseverated word with increasing frequency.
          Logoclonia: the last syllable of the last word is repeated.


Recent Definitions of Bizarre delusion
  1. apparent physical or logical impossibility (implying extreme implausibility)
  2. presence of a belief that is not consensually shared in a given social or cultural context
  3. absence of historical or  genetic understanding: this refers to an inability to understand how a given state of mind could emerge from relevant biographical antecedents
  4. incomprehensibility, in the sense of a lack of "static understanding": this refers to the capacity to empathize with, to imaginatively identify with, a given state of mind
  5. notion of "not being derived from ordinary life situations."

TANGENTIALITY
Oblique, disgressive, irrelevant manner of speech in which the central idea is not
communicated at all. . It refers only to questions and not to transitions in spontaneous speech

 Incoherent, essentially incomprehensible mixture of words and phrases
         .

PRESSURE OF SPEECH

         More than 150 words / minute
         Increase in amount of spontaneous speech
         Sentences left incomplete with new ideas coming up
         Absence of social stimuli
         Difficult to interrupt
         Loud and emphatic
POVERTY OF SPEECH
   Decreased amount of spontaneous speech
   Monosyllables

DERAILMENT  (loose associations, flight of ideas) –
 A pattern of spontaneous speech, in which the ideas slip off the track onto another one.
a.   Flight of ideas is a derailment that occurs rapidly in the context of pressured speech.
b.   In circumstantiality, the speaker realizes that he has gotten off the track and return to his original subject
INCOHERENCE (WORD SALAD, JARGON APHASIA, SCHIZOPHASIA) –
 Pattern of speech that is essentially incomprehensible at times.
Mechanisms
                                                               i.      Rules of grammar and syntax are ignored
                                                             ii.      Portions of coherent sentences may be observed in the midst of a sentence that is incoherent as a whole
                                                            iii.      Semantic level – words are substituted in a sentence so that the meaning of the sentence is lost
Diff from derailment – Abnormality occurs at the level of the sentence, with in which words or phrases are joined incoherently while in derailment unclear or confusing connections between larger units like ideas or sentences is seen





ATHETOSIS

AKATHISIA
Subjective feeling of psychological restlessness associated with
motor restlessness manifested by a compelling need to be in constant

medications and SSRIs. Akathisia has to be differentiated from psychotic
agitation. Motor restlessness in the absence of psychological restlessness is
referred to as pseudoakathisia.

stimuli, which cannot be explained by a defect in sensory pathways or cerebral
lesion. The term has also been used to refer to the selective loss or disuse of
knowledge of specific objects because of emotional circumstances, as seen in certain
schizophrenic, anxious, and depressed patients.
(1) Astereognosis (tactile agnosia) is defined by the inability to recognize
objects based on touch, although the primary somatosensory modalities—light
touch, pressure, pain, temperature, vibration, and proprioception—are intact The lesion in Astereognosis is, localized at the border of the somatosensory and association areas in the posterior parietal lobe.
(2) Visual Agnosia –
i. Apperceptive visual agnosia is the inability to identify and draw items
using visual cues, with preservation of other sensory modalities.
ii. Associative visual agnosia is the inability to name or use objects despite
the ability to draw them.
iii. Color agnosia is the inability to recognize a color despite being able to
match it.
(3) Auditory sound agnosia, is defined as the inability to recognize nonverbal sounds,
