Study Notes
Psychosis
- Extreme reality distortion
- Characterized by delusions and hallucinations
- Delusions: fixed beliefs despite contradictory evidence (e.g., persecution, reference, influence, Cotard's, Capgras)
- Hallucinations: sensory experiences without external stimuli (e.g., auditory, visual, olfactory, gustatory)
- Diagnosed when delusions and thought processes are extremely bizarre and excessive.
Schizophrenic Spectrum Disorders
- A range of conditions, including:
- Schizotypal personality disorder
- Delusional disorder
- Brief psychotic episode
- Schizophreniform disorder
- Schizophrenia (most prevalent), also called schizoaffective disorder
Schizophrenia
-
Diagnosis Criteria:
- Presence of both positive and negative symptoms of psychosis, for at least 6 months.
- Florid symptoms (hallucinations and delusions) for at least one month.
- Onset typically in teens and young adulthood.
- Heterogeneity: Varied symptoms and levels of functioning in individuals.
-
Positive Symptoms:
- Delusions: Fixed false beliefs resistant to counterarguments; types include persecution, reference, influence, Cotard's, and Capgras
- Hallucinations: Sensory experiences without external cause (auditory most common, followed by visual, olfactory, and gustatory)
- Disorganized speech: Derailment, tangential thinking, incoherence, neologisms (new words), and clang associations (rhyming words)
- Disorganized behavior: Childlike silliness, unpredictable agitation, catatonic motor behavior (waxy flexibility, inability to move)
-
Negative Symptoms (Criterion A):
- Flat affect: Lack of emotional expression
- Avolition: Lack of motivation
- Alogia: Poor speech or lack of content
- Anhedonia: Inability to experience pleasure
- Asociality: Reduced social interaction
- Criterion B: Social/occupational impairment (education, employment, social relationships)
- Criterion C: Symptoms persisting for at least 6 months.
Clinical Picture of Schizophrenia
- Prevalence: Relatively low (approximately 1%)
- Onset: Often gradual (prodromal period)
- Gender Differences: Men tend to develop it earlier (late teens), and women in their mid-20's.
- Course: Variable, ranging from single episode and recovery to multiple episodes and remissions, and chronic progressive worsening.
- Insight: Variable levels of understanding of their illness
- Cultural Influences: The rates may vary across different cultures
- Prognosis: Reduced life expectancy (approximately 10 years less), higher risk of suicide and co-occurring conditions (such as cardiovascular disease, metabolic issues, and diabetes) and substance abuse (especially cannabis)
