Schizophrenia01:17

Schizophrenia

863
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...

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

572
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.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Psychological and Sociocultural Causes of Schizophrenia

532
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...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

532
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,...

Hybrid Zones02:29

Hybrid Zones

21.8K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Positive Symptoms Schizophrenia: Hallucinations and Delusions

542
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.

Area of Science:

  • Neuroscience
  • Artificial Intelligence
  • Medical Diagnostics

Background:

  • Schizophrenia (SCZ) is a severe mental health condition with increasing incidence and overlapping symptoms, necessitating early diagnosis for effective intervention.
  • Traditional machine learning methods for SCZ detection require extensive feature engineering, limiting their efficiency and objectivity.
  • Deep learning (DL) offers advanced capabilities for analyzing complex patterns in neurophysiological data, paving the way for objective diagnostic tools.

Purpose of the Study:

  • To propose a novel hybrid deep learning approach for the early diagnosis of schizophrenia using electroencephalogram (EEG) data.
  • To enhance EEG signal preprocessing and clarity through the Mutation-enhanced Archimedes Optimization (MAO) algorithm.
  • To develop an integrated deep learning framework (CNN-GRU-MAO) for improved schizophrenia detection accuracy.

Main Methods:

  • Developed a hybrid deep learning model combining Convolutional Neural Network (CNN) and Gated Recurrent Unit (GRU) for analyzing spatial and temporal EEG features.
  • Integrated the Mutation-enhanced Archimedes Optimization (MAO) algorithm into the CNN-GRU architecture (CNN-GRU-MAO) for enhanced preprocessing and optimization.
  • Employed a dual-objective optimization strategy focusing on detection accuracy and noise reduction to improve overall model performance.

Main Results:

  • The proposed CNN-GRU-MAO model achieved high performance metrics: 98.41% accuracy, 98.13% precision, 98.87% recall, 98.49% F1-score, and 97.78% specificity.
  • The MAO technique significantly improved EEG signal integrity, enhancing Signal-to-Noise Ratio (SNR) and Signal-to-Interference Ratio (SIR) while reducing artifact contamination.
  • The hybrid deep learning approach demonstrated superior performance compared to traditional methods in schizophrenia detection.

Conclusions:

  • The Mutation-enhanced Archimedes Optimization (MAO) method is highly effective for EEG preprocessing in schizophrenia detection.
  • Integrating deep learning frameworks with advanced optimization techniques offers a transformative approach to mental health diagnostics through neurophysiological signal analysis.
  • The developed CNN-GRU-MAO model represents a significant advancement in achieving precise and objective early diagnosis of schizophrenia.
