Summary
Neuroimaging reveals brain changes in schizophrenia, showing impairments in executive functions and memory. Cognitive remediation interventions may improve brain function and offer neuroprotection.
Area of Science:
- Neuroimaging
- Cognitive Neuroscience
- Psychiatry
Background:
- Schizophrenia is characterized by significant cognitive impairments, particularly in executive functions and episodic memory.
- These deficits substantially impact daily functioning.
- Neuroimaging techniques are crucial for understanding the underlying brain alterations.
Purpose of the Study:
- To review neuroimaging findings on the brain correlates of cognitive impairments in schizophrenia.
- To explore how cognitive remediation interventions affect brain structure and function.
- To highlight the potential of neuroimaging in tracking treatment-induced changes.
Main Methods:
- Review of neuroimaging studies (structural, functional, connectivity) in schizophrenia.
- Analysis of brain regions associated with executive function and memory deficits.
- Examination of changes observed after cognitive remediation.
Main Results:
- Executive function deficits linked to prefrontal cortex alterations and anterior cingulate cortex activity.
- Episodic memory impairments associated with hippocampal changes.
- Cognitive remediation shows improvements in prefrontal and thalamic regions, suggesting neural reorganization.
Conclusions:
- Neuroimaging provides insights into brain mechanisms of cognitive dysfunction in schizophrenia.
- Cognitive remediation may induce structural and functional brain changes, potentially offering neuroprotection.
- Multimodal neuroimaging and advanced models are needed for future research.

546
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,...

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...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:29Biological Causes of Schizophrenia
596
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.

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...

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...
