Study Notes

Schizophrenia Spectrum and Other Psychotic Disorders: Symptoms, Prevalence, and Historical Conceptualizations

Psychosis can refer to a variety of disorders or syndromes, or a range of symptoms.
Psychotic disorders are distinguished from one another in terms of symptom configuration and duration.
Psychotic symptoms include delusions, hallucinations, disorganized thinking (speech), grossly disorganized or abnormal motor behavior, and negative symptoms.
Delusions can be categorized into six types based on their content and focus.
Hallucinations are perception-like experiences that occur without an external stimulus and may occur in any sensory modality.
Disorganized thinking or speech is typically inferred from the individual's speech pattern.
Grossly disorganized or abnormal motor behavior may manifest itself in a variety of ways, ranging from childlike "silliness" to unpredictable agitation.
Negative symptoms include reductions in the expression of emotions, decrease in motivated self-initiated purposeful activities, diminished speech output, decreased ability to experience pleasure, and lack of interest in social interactions.
Psychotic symptoms are present in about 5% of the general population who are not seeking help, 25% of people with common mental disorders, and around 80% of patients with psychotic disorders.
Schizophrenia has a lifetime prevalence of 1-2%, with a 3:2 male-to-female ratio and a peak age of onset in late adolescence/early adulthood.
Individuals with schizophrenia spectrum disorders have an increased risk of perpetrating violent outcomes, but most individuals experiencing psychosis are not violent and do not display aggressive or dangerous behavior.
Historical conceptualizations of schizophrenia include "demence precoce," "dementia praecox," "schizophrenia," and the neo-Kraepelinian view.
The DSM-III, published in 1980, introduced narrow diagnostic criteria for schizophrenia and five subtypes: paranoid, disorganized, catatonia, undifferentiated, and residual.Understanding Schizophrenia and Psychosis: Biological and Psychological Factors, Risk Factors, and Treatment
Current conceptualizations of schizophrenia and psychosis call for prospective studies of first-episode patients and prodromal patients.
Richard Bentall argues for studying psychotic symptoms individually rather than schizophrenia as a construct.
At least 100 genes are involved in psychosis, and epigenetic approaches are being explored, such as the COMT gene's interaction with cannabis.
Biological factors involved in schizophrenia and psychosis include excessive dopamine function in the CNS, reduced brain tissue, and impaired cognitive function.
Social cognition plays a role in schizophrenia and psychosis, affecting the ability to comprehend emotional and communicative cues.
Childhood trauma is a significant risk factor for psychosis, with negative personal evaluations and low self-esteem mediating associations between trauma and psychotic symptoms.
Cannabis use is associated with an increased risk of developing schizophrenia, with daily cannabis users having rates of psychotic symptoms that are between 1.6 and 17 times higher.
Substance use, medication non-adherence, and poor family interactions are risk factors for relapse in schizophrenia and psychosis.
The impact of relapse and chronic illness includes unemployment, housing difficulties, poor physical health, and premature death.
Pharmacological treatment is the primary approach in the acute phase of illness, with best practices advocating for a low-dose approach and the use of atypical antipsychotics.
Psychological treatments, such as cognitive-behavioral therapy, family education, and psychoeducation, are also effective in treating schizophrenia and psychosis.
Ongoing issues in understanding schizophrenia and psychosis include the lack of biological markers or physiological tests for diagnosis, uncertain etiology, and ongoing debate about the validity of the diagnosis.
Stigma surrounding schizophrenia and psychosis is damaging, as it limits opportunities for recovery and increases stress for individuals with the disorder.
