Summary
Attenuated Psychosis Syndrome (APS) is often misdiagnosed. Most clinicians view APS symptoms as a full psychotic disorder, suggesting a need for better diagnostic criteria in DSM-5.
Area of Science:
- Psychiatry
- Clinical Psychology
- Mental Health Diagnostics
Background:
- Attenuated Psychosis Syndrome (APS), or schizophrenia prodrome, involves subthreshold psychotic symptoms and functional decline.
- These symptoms are linked to significant disability and predict future psychosis.
- Current diagnostic systems lack clear criteria for APS, leading to conceptual ambiguity among professionals.
Purpose of the Study:
- To investigate how clinical psychologists, psychiatrists, and general practitioners conceptualize and appraise Attenuated Psychosis Syndrome (APS).
- To assess clinicians' diagnostic practices concerning subthreshold psychotic symptoms.
- To inform potential diagnostic revisions for APS in the upcoming DSM-5.
Main Methods:
- A national survey of 303 mental health practitioners (psychologists, psychiatrists, general practitioners).
- Participants responded to vignettes depicting psychosis, subthreshold psychosis (APS), and no psychotic symptoms.
- Analysis focused on clinicians' appraisal and diagnostic tendencies for each vignette.
Main Results:
- Practitioners' responses indicated that APS is frequently viewed as a distinct mental disorder.
- A majority of clinicians may diagnose APS as a full threshold psychotic disorder.
- Findings suggest inconsistent conceptualization and potential over-pathologization of APS.
Conclusions:
- The inclusion of an APS category in DSM-5 could enhance diagnostic reliability.
- Standardized criteria for APS may improve clinical practice and reduce diagnostic ambiguity.
- Further research is needed to refine diagnostic approaches for individuals at risk for psychosis.

01:28Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
01:22Personality Disorders: Paranoid and Schizoid
Personality disorders represent enduring cognition, affect, and behavior patterns that significantly deviate from societal norms. These maladaptive traits often lead to difficulties in various domains, including interpersonal relationships, occupational settings, and overall psychological well-being. Paranoid personality disorder and schizoid personality disorder are two distinct conditions marked by odd or eccentric behavior.

01:26Positive Symptoms Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

01:29Psychological and Sociocultural Causes of Schizophrenia
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...
