Classification of Illness01:17

Classification of Illness

7.6K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

103
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...

Schizophrenia

144
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...

Psychological and Sociocultural Causes of Schizophrenia

142
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...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

755
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...

Classification of Neurotransmitters

3.1K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Area of Science:

  • Neuroscience
  • Computational Psychiatry
  • Medical Informatics

Background:

  • Schizophrenia significantly impacts perception and response to stimuli.
  • Electroencephalography (EEG) is a valuable, non-invasive tool for brain disorder assessment.
  • Manual EEG analysis is time-consuming, necessitating automated methods.

Purpose of the Study:

  • To develop and evaluate a machine learning (ML) method for automated EEG analysis in schizophrenia.
  • To assess the performance of an eXtreme Gradient Boosting (XGB) algorithm for classifying schizophrenia patients.

Main Methods:

  • An ML approach utilizing the XGB algorithm was developed for analyzing EEG signals.
  • The XGB method's performance was compared against four other supervised ML algorithms.
  • Key performance metrics included Area Under the Curve (AUC) and accuracy.

Main Results:

  • The proposed XGB-based method achieved superior performance with an AUC of 0.94 and accuracy of 0.94.
  • The system demonstrated high accuracy and robustness in classifying schizophrenia patients from EEG data.
  • XGB outperformed the other four supervised ML methods evaluated in the study.

Conclusions:

  • The XGB-based ML method offers a highly accurate and robust approach for schizophrenia detection via EEG.
  • This automated system can serve as a valuable complementary tool to support clinical diagnosis in hospitals.
  • The findings suggest potential for improved efficiency and accuracy in diagnosing schizophrenia.
