Persistent auditory hallucinations in out-patients with schizophrenia
La Tunisie Medicale
|November 2, 2016
Summary
Approximately 40% of schizophrenia patients experience persistent auditory hallucinations (AHs). These symptoms, characterized by number, influence, and reality, are linked to poor prognosis and require enhanced therapeutic strategies.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Auditory hallucinations (AHs) are a core symptom of schizophrenia.
- Understanding the prevalence, dimensions, and clinical correlates of persistent AHs is crucial for effective treatment.
Purpose of the Study:
- To estimate the prevalence of persistent AHs in schizophrenia patients.
- To evaluate the dimensions of these hallucinations.
- To identify clinical factors associated with persistent AHs.
Main Methods:
- Cross-sectional study of 144 out-patients diagnosed with schizophrenia (DSM-IV-TR).
- Data collection included epidemiological, clinical, and therapeutic information.
- Utilized Hoffman's Auditory Hallucinations Rating Scale (AHRS) and the Positive and Negative Symptoms Scale (PANSS).
Main Results:
- The prevalence of persistent AHs (AHRS score ≥ 5) was 40.3%.
- Higher AHRS scores were observed in patients with persistent AHs (19.4±7.7) compared to all patients (10.7±7.8).
- Key associated factors included absence of tobacco use, hallucinatory onset, prior hospitalization, and continuous illness course.
Conclusions:
- Auditory hallucinations are multidimensional, with significant inter-individual differences.
- Persistent AHs are associated with a poorer prognosis in schizophrenia.
- More effective therapeutic strategies are needed for persistent AHs.

868
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.

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...

01:29Psychological and Sociocultural Causes of Schizophrenia
756
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...

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.

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...
