まとめ
健康データと組み合わせた網膜画像は,精神病スペクトル障害 (PSD) の異なるサブグループを特定することができます. このアプローチは網膜の構造と社会経済的要因の違いを明らかにし,精密精神医学を助けます.
科学分野:
- 神経科学
- 眼科について
- 精神科
背景:
- 精神病スペクトル障害 (PSD) は網膜の変異と健康/認知プロファイルに関連しています.
- 網膜と生体心理学的データを組み合わせて,異なるPSDサブグループを定義できるかどうかは不明である.
研究 の 目的:
- 網膜構造と生体心理社会的要因の多変量共変が,精神病スペクトル障害内の生物学的に異なるサブグループを特定できるかどうかを調査する.
- 精密精神医学における網膜微細構造分析の可能性を調査する.
主な方法:
- 英国バイオバンクからのPSDとPSDのない成人の間では,光学コヒーレンストモグラフィー (OCT) を用いて層分別網膜の厚さを測定した.
- カノニカル・コレレーション・アナリスト (CCA) は,網膜測定値と生体心理社会的データ (社会統計学,心代謝,眼,認知) のコヴァリエーションを調査した.
- 階層的なクラスタリングは,特定された共変パターンに基づいてサブグループを導出するために使用され,その後,FDR補正による一般的な線形モデルを使用した比較が行われました.
主要な成果:
- 有意な多変量関連パターンは,より薄い網膜 (特に外層) と社会経済的欠乏,より高いBMI,より低い視力,およびより低い認知能力 (r=0. 468,p<.0001) を関連付けました.
- 2つの安定したサブグループが出現した. "網膜保存" (より多くのコントロール,より厚いRNFL) と"網膜障害" (より多くのPSD,より薄い斑点/RNFL/光受容体層,より低い社会経済的地位).
- "網膜障害"のグループは"網膜保存"のグループと比較して,複数の層にわたる網膜の厚さが著しく低下し,社会経済的要因が低下しました.
結論:
- PSDを生物学的意味のあるサブグループに分類するための非侵襲的な方法として,層解析されたOCTをバイオサイコ社会的データと統合します.
- 網膜の微細構造分析は,従来の症状に基づく分類を超えて精密精神医学を前進させるための翻訳的可能性を秘めています.

Psychological and Sociocultural Causes of Schizophrenia
185
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, 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.

Theoretical Approaches to Psychological Disorder
326
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
