History
Emil Kraepelin
1856–1926 German
Psychiatrist developed
The concept of dementia
Praecox (premature dementia)
![Page 55: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/55.jpg)
History
Paul Eugen Bleuler
1857 –1939
Swiss psychiatrist
coined the term
Schizophrenia.
![Page 56: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/56.jpg)
HistorySimilar signs and symptoms are traced from ancient
documents by the Egyptians as far back as 2000 B.C.
Mental disturbances were associated with demons and
Evil spirits.
Spirits could be excised through such varied
means as music therapy or dangerous and deadly
means of drilling holes in patients skulls.
To let the demons out, other signs and symptoms
have been described in ancient writings by the
Greeks, Romans, and Chinese.
![Page 57: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/57.jpg)
History of Diagnosis• “Associative splitting: separation among
basic functions of human personality (cognition, emotions, perception) that was seen by some as the defining characteristics of Schizophrenia.
• Bleuler split the divided symptoms into either positive or negative in 1911 and divided the illness into four categories:• The four A’s: (autism, ambivalence, blunted
affect, and loosening of associations).”
![Page 58: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/58.jpg)
Four A’s: Fundamental symptoms
1. Autism: unresponsive to the world2. Ambivalence: presence of
contradictory drives, tendencies, emotions or thoughts
3. Affective disturbances: problems in feeling or expressing full range of emotions
4. Associative disturbances: thinking & ideas are not connected.

– If symptoms persist beyond 6 months a diagnosis of Schizophrenia is needed
– 1/3 recover within 6 months, 2/3 progress to Schizophrenia or Schizoaffective Disorder.

295.10 Disorganized Type
“The essential feature of the disorganized
type of Schizophrenia are disorganized
speech, disorganized behavior, and flat or
inappropriate affect. The disorganized
speech may be accompanied by silliness and
laughter that are not closely related to the content of
the speech. The behavioral disorganization (i.e.,
lack of goal orientation) may lead to severe
disruption in the ability to perform activities of daily
living…” DSM-IV-TR (2000) p. 314

295.30 Paranoid Type
“The presence of prominent delusions or
auditory hallucinations in the context of a
relative preservation of cognitive functioning
and affect.” DSM-IV-TR (2000) p. 313
“Delusions are typically persecutory or
grandiose, or both, but delusions with other
themes (e.g., Jealousy, religiosity, or
somatization) may occur.” (Ibid) p. 313

295.60 Residual Type
“The residual type of Schizophrenia should
be used when there has been at least one
episode of Schizophrenia, but the current
clinical picture is without prominent positive
psychotic symptoms (e.g., delusions,
hallucinations, disorganized speech or
behavior).” DSM-IV-TR (2000) p. 316

295.90 Undifferentiated Type
“The essential feature of undifferentiated
type of Schizophrenia is the presence of
symptoms that meet Criterion A of
Schizophrenia but that do not meet criteria
for the paranoid, disorganized, or catatonic
type.” DSM-IV-TR (2000) p. 316

Associated Features
• Poor insight into acknowledgement of the disease.
• Poor insight is a symptom of disease, not a failure to cope with diagnosis.
• Controversy exists whether persons diagnosed with Schizophrenia exhibit greater incidences' of violence.

EtiologySchizophrenia is one
of the most serious,
and most mysterious
of all mental illnesses.
It has been described
as a monster, a
chimera and a
disaster for those who
get it.
What is it’s source?
![Page 76: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/76.jpg)
EtiologyMany theories stress unfavorable social and emotional experiences as the probable cause. Harmful family influences or faulty child-rearing practices are blamed during the formative years. Some theorists claim the “double-bind” (no-win) situation as critical: “…the patient’s mother was always ready to criticize him for doing one thing and rejecting him for doing the opposite, resulting in constant frustration.”

Etiology• Other researchers see Schizophrenia as a
physical disease of the nervous system. For example, the patient may be “intoxicated” by some chemical (possibly similar to LSD, DMT, or mescaline) which his body may be producing due to a genetically inherited error in metabolism.
• Recently, advances in technology (supported by brain imaging ) and research findings suggest that Schizophrenia is a biologically based disease of the brain.

Diathesis – Stress Model
The diathesis-stress model is a model that combines interaction of biological and genetic factors to explain disorders. Diathesis refers to a hereditary predisposition toward disease or disorder.

Diathesis Stress – Model
• “Figure 1 illustrates a contemporary version of the diathesis-stress model that encompasses all of the factors that are currently considered to play a significant etiologic role in Schizophrenia. This model postulates that constitutional vulnerability to Schizophrenia (i.e., The diathesis) can result from both inherited and acquired constitutional factors.” p. 422 walker et. al.

Diathesis Stress - Model
• “The picture that has emerged from research on Schizophrenia, as well as other psychotic disorders, is best described in an expansion of the diathesis stress model that has dominated the field for several decades.” P.422 walker et.al.,

Preschizophrenic Children • Premorbid Development
– Schizophrenia is diagnosed in late adolescence or early childhood (normally)
– Signs are usually present before diagnosis, subtle but can be seen when compared to adolescence with healthy outcomes
• Cognitive Functioning of children who later develop Schizophrenia– Perform below age level– Poor grades– Has hard time interpreting information and able to use
that information– Inability to sustain attention
![Page 84: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/84.jpg)
Preschizophrenic Children• Social Situations
– Less responsive– Less positive emotion– Poor social adjustment– More negative facial expressions during first year
of life
• Motor Development– Delays and abnormalities– Late walkers
*Early and middle childhood aged children
are rarely diagnosed with Schizophrenia.
![Page 85: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/85.jpg)
Adolescence
• Symptoms– Major adjustment problems– Depression– Social withdrawal– Irritability– Noncompliance
*The problem is these symptoms do not go along with just Schizophrenia they are present in mood disorders, substance abuse, and some other behavioral disorders
![Page 86: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/86.jpg)
Schizotypal Personality Disorder (SPD) • Sometimes preschizophrenic adolescents have sings
of psychotic symptoms, the DSM IV defines these as SPD
• Diagnostic Criteria for SPD – Social anxiety/withdrawal– Affective abnormalities– Eccentric behavior– Unusual ideas
• Persistent beliefs in extrasensory phenomena
– Unusual sensory experiences• Repeated experiences with confusing noises with peoples voices• Seeing objects move
*(All of these symptoms are recurring) *Schizotypal Personality Disorder patient’s symptoms are not as severe as
having delusions or hallucinations
![Page 87: Schizophrenia](https://reader033.fdocuments.net/reader033/viewer/2022060107/55496691b4c9056e598b4890/html5/thumbnails/87.jpg)
Schizotypal Personality Disorder Schizophrenia
• The transition from SPD to Schizophrenia usually happens in young adulthood
• Studies show that 10% to 40% of youth with SPD signs eventually show an Axis I Schizophrenia spectrum disorder
• The others with SPD either end up with adjustment problems or a complete decrease of symptoms in young adulthood
*Research is being done to see if prevention programs could be used with youth with SPD to prevent Schizophrenia from developing

SPD and Schizophrenia have some similar functional
abnormalities• Motor abnormalities
• Cognitive deficits
• Increase in cortisol (stress hormone)
