- 統合失調症に関する研究
背景:
- 最初のエピソード統合失調症 (SCZ) は,効果的な早期治療予測を必要とします.
- 抗精神病薬への反応は,患者によって著しく異なります.
- 治療結果に関する予測モデルの開発は極めて重要です.
研究 の 目的:
- 最初のエピソードSCZにおける早期の抗精神病反応を予測するために,頭蓋骨CTベースの放射学モデルを開発し,検証する.
- 治療反応に関連する放射性特徴を特定する.
- 放射線学と臨床的要因を統合して,予測の精度を向上させる.
主な方法:
- 530人の抗精神病薬未使用初発性SCZ患者の遡及的分析.
- 放射性特徴 (RF) は,頭蓋骨CT画像から抽出され,複数の段階のパイプラインを使用して選択されます.
- XGBoost分類器とロジスティック回帰は,放射線スコア (Rad-Score) と臨床予測値を組み合わせたノモグラムを含む予測モデルを構築するために使用されます.
主要な成果:
- 11のRFと1つの相互作用項,主に部とタラムスの領域から,保持されました.
- 放射線学のみのモデルは,0.86のAUCを達成し,臨床のみのモデル (AUC=0.72) を上回りました.
- Rad-Scoreと臨床的要因を統合したノモグラムは,AUC 0.92を達成し,症状の改善と相関していました (rs=0.504).

Schizophrenia
1.1K
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 Schizophrenia
671
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.

Psychological and Sociocultural Causes of Schizophrenia

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 and Antipsychotic Drugs: Overview
939
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...

Antipsychotic Drugs: Therapeutic Uses and Side Effects
864
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...
