  • Severity – more wore in men sue to more negative symptoms and less able to function in society
  • Hebephrenic = DisorganisedThe DSM-IV-TR contains five sub-classifications of schizophrenia, although the developers of DSM-5 are recommending they be dropped from the new classificationThe ICD-10 defines two additional subtypes.Post-schizophrenic depression: A depressive episode arising in the aftermath of a schizophrenic illness where some low-level schizophrenic symptoms may still be present. (ICD code F20.4)Simple schizophrenia: Insidious and progressive development of prominent negative symptoms with no history of psychotic episodes.

    2. 2. To Know Schizophrenia is to know Psychiatry<br />The most devastating illness that psychiatrist treat.<br />One of the most challenging disease in medicine<br />1% of population has schizo.<br />An enormous economic burden<br />? A major health concern<br />
    3. 3. Stories of Schizophrenia<br />
    4. 4. History<br />Emil Kraepelin- original term-dementia praecox-early age, chronic deteriorating course.<br />EugenBleuler- coined the term schizophrenia (split mind)  affective blunting, loosening of associations, autism (withdrawal) and ambivalence (coexisting conflicting ideas) - 4 As- earned acceptance in USA<br />Kurt Schneider  first rank symptom<br />
    5. 5. Psychotic mental disorder of unknown aetiology characterized by disturbances in<br />Thinking (e.g. distortion of reality, delusions and hallucinations)<br />Mood (e.g. ambivalence, inappropriate affect)<br />Behaviour(e.g. Apathetic withdrawal, bizarre activity)<br />at least 6 months<br />Definition <br />
    6. 6. Epidemiology<br />
    7. 7. Epidemiology: Sex<br />
    9. 9. Aetiology<br />Uncertain; however there is evidence for several risk factors.<br />Several models which can be grouped into….<br />
    10. 10. Aetiology – Bio<br />Genetics Consideration<br />1st degree & 2nd degree relative<br />Environmental<br />Abnormalities of pregnancy and delivery [2%]<br />Maternal Influenza – 2nd trimester [2%]<br />Fetal Malnutrition [2%]<br />Winter & Low Social Class birth [1.1%]<br />
    11. 11.
    12. 12. Social<br />Studies have shown an excess of schizophrenic patients in lower socioeconomic groups and in urbanised areas. This used to be attributed to “social drift”<br />Cannabis abusers [2%]<br />
    13. 13. Psychological<br />abnormalities in processing sensory information, in separating “signal from background noise”, or in manipulating abstract information<br />Excess life traumas against controls at first presentation<br />
    14. 14. Pathophysiology<br />disorder of dopaminergic function:<br />related to increased dopamine activity in certain neuronal tracts.<br />Other neurotransmitter abnormalities implicated in schizophrenia:<br />elevated serotonin.<br />elevated norepinephrine.<br />decreased gamma- aminobutyric acid (GABA).<br />
    15. 15. Schizophrenia Subtypes<br />Classically divided into five subtypes<br />Paranoid[stable, often persecutory delusion/hallucinations only]<br />Hebephrenic[thought/affective changes + -ve symptoms]<br />Undifferentiated [psychosis w/out clear predominance]<br />Catatonic[prominent psychomotor disturbances]<br />Residual [low intensity +vesymtoms]<br />

    18. 18. DIAGNOSIS CRITERIA OF SCHIZOPHRENIA<br />The diagnosis of schizophrenia is based entirely on the clinical presentation – history and examination.<br />
