Summary
Executive function impairments in schizophrenia are linked to persistent self-disorders (SDs). Poorer baseline executive functions predicted more SDs and smaller reductions in SDs over seven years.
Area of Science:
- Psychiatry
- Neuroscience
- Clinical Psychology
Background:
- Basic self-disorders (SDs) and neurocognitive impairments are core features of schizophrenia spectrum disorders.
- Little research exists on the link between SDs and neurocognition in schizophrenia, with no prior longitudinal studies.
Purpose of the Study:
- To investigate the longitudinal association between self-disorders (SDs) and neurocognitive function in schizophrenia patients.
Main Methods:
- 35 schizophrenia patients were assessed at baseline and 7 years later.
- Self-disorders were measured using the Examination of Anomalous Self-Experience (EASE).
- Neurocognitive functions assessed included psychomotor speed, executive functions, and memory.
Main Results:
- Poorer baseline executive functions were significantly associated with higher levels of SDs at 7-year follow-up.
- Impaired executive functions predicted smaller reductions in SDs over the study period.
- No significant associations were found between other neurocognitive functions and SDs.
Conclusions:
- Executive functions are crucial for self-regulation in schizophrenia.
- Impairments in executive functions may influence the development and persistence of self-disorders over time.

111
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

01:29Psychological and Sociocultural Causes of Schizophrenia
155
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...

01:30Negative and Cognitive Symptoms of Schizophrenia
104
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

177
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

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...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
