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.
