22. Schizophrenia/Psychotic Disorders Flashcards
named the disorder schizophrenia and identified a group of schizophrenias
Eugen Bleuler
differentiated behaviors of schizophrenia and categories them into ranks
Kurt Schneider
risk factors of schizophrenia
genetics and environment
- first-degree biologic relatives w/ greater risk (parents/siblings)
- unstable family/chaotic household
- homeless/poverty
- extreme stress
- maternal/prenatal factors
- early life cannabis use
age of onset of schizophrenia
usually late adolescence or early adulthood
gender differences in schizophrenia
earlier diagnosis and poorer prognosis in men
neuroanatomic findings w/ schizophrenia
- larger lateral and third ventricles
- smaller total brain volume
comorbidities associated w/ schizophrenia
- substance abuse and depression
- DM and obesity
- disturbed water balance (polydipsia and disturbed electrolyte imbalances)
Why is it necessary to assess for depression in patients w/ schizophrenia
- may suggest a mood disorder diagnosis is more appropriate
- common in chronic stages of schizophrenia and deserves attention
- suicide rate among people w/ schizophrenia is higher than general population (want voices to stop or may have voices telling them to do it)
risk factors for suicide among pts w/ schizophrenia
- untreated psychosis
- under 28 y/o
- Hx of suicide attempts
- severity of depression and substance abuse
social stressors that contribute to changes in brain function
- social stigma
- absence of good, affordable, and supportive housing
- fragmented mental health care delivery system
clinical course of schizophrenia
- prodromal period
- acute illness (schizophrenia)
- stabilization (residual phase)
- maintenance and recovery
- relapse
T/F: a person’s prognosis w/ schizophrenia is worse if their first episode of psychosis occurs at an earlier age
True
factors associated w/ having a good prognosis
- having a good premorbid period (sxs not severe)
- later onset in life
- good healthy coping skills
- psychotic outbreak brief
phase w/ decline in overal function; pt is withdrawn, irritable, may have physical complaints; newfound interest in religion
prodromal period
phase w/ prominent positive and negative sxs; person unable to work, social relationships deteriorate, and hygiene is severely neglected; unable to care for basic needs; common to engage in substance use during this phase
acute illness (schizophrenia)
phase where person is on medication that should help; sxs become less acute but still lingering; negative sxs hardest to treat
stabilization (residual phase)
phase where you make sure pt is compliant w/ meds and removing stress from life; assess their support system and protective factors
maintenance and recovery
phase can occur at any time and for any reason; pt may stop taking their meds (main cause)
relapse
symptoms that are added to or not present in healthy individuals
positive sxs
examples of positive sxs
- hallucinations
