    Study Notes

    Symptoms of Psychosis

    • Positive symptoms include hallucinations, delusions, disorganized speech, and grossly disorganized behavior.
    • Avolition is a negative symptom, characterized by lack of motivation.

    Diagnosis of Schizophrenia

    • Symptoms must persist for at least six months according to DSM-5 guidelines.
    • Coined by Eugen Bleuler, the term "schizophrenia" emphasizes its complexities.

    Types of Delusions

    • Grandiose delusions involve beliefs in possessing special powers or abilities.
    • Other types include persecutory, somatic, nihilistic, and erotomanic delusions.

    Negative Symptoms of Psychosis

    • Examples include avolition, alogia (poverty of speech), and catatonia, marked by severe emotional response reduction.

    Understanding Double Negatives

    • A double negative question implies confusion and may lead to varied interpretations; for example, "not uncommon" or "not unexpected."

    Phases of Psychosis

    • The prodromal phase is characterized by gradual deterioration, while the acute phase displays persistent severe symptoms.
    • The late recovery phase involves management of ongoing symptoms.

    Neurotransmitter Involvement

    • Dopamine is primarily associated with both the dopamine hypothesis of schizophrenia and positive symptoms.
    • Other neurotransmitters, such as serotonin or GABA, do not primarily influence schizophrenia.

    Schizoaffective Disorder

    • This disorder combines symptoms of schizophrenia and major depressive disorder or bipolar disorder.

    Prevalence and Hallucinations

    • Approximately 60-70% of patients with schizophrenia report experiencing hallucinations.
    • Schizophrenia prevalence in the general population is about 1-2%.

    Treatment Focus

    • Antipsychotic medications primarily aim to reduce psychotic symptoms, addressing both delusions and hallucinations.
    • Family therapy emphasizes reducing expressed emotion to improve treatment outcomes.

    Types of Psychotic Disorders

    • DSM-5 includes schizoaffective disorder, schizophrenia, schizophreniform disorder, and brief psychotic disorder as formal diagnoses. Delusional disorder also features persistent delusions without other schizophrenia symptoms.

    Characteristics of Hallucinations

    • Types of hallucinations can be auditory, visual, olfactory, or tactile, but not affective.

    Understanding Stigma and Therapy

    • Social stigma can significantly impact individuals with psychosis, and therapy aims to strengthen coping mechanisms and medication adherence.

    Overall Knowledge

    • The diathesis-stress model highlights the interaction between genetic predispositions and environmental stressors, contributing to the emergence of psychotic disorders.
