まとめ
若者における最初のエピソード統合失調症 (FES) は,血管内皮成長因子 (VEGF) の低値と関連しています. これらのVEGFレベルは 統合失調症の特定の症状である 組織的混乱や感情的苦痛を示唆する可能性があります
科学分野:
- 神経科学
- 精神科
- 生物化学
背景:
- 青春期と成人期は 脳の発達に不可欠です
- 青年期における最初のエピソード統合失調症 (FES) はあまり研究されていない.
- 血管内皮成長因子 (VEGF) がFESの精神病理と認知において果たす役割については,さらなる調査が必要である.
研究 の 目的:
- FESを持つ若者の血清のVEGFレベルを調査する.
- FESにおけるVEGFレベルと臨床症状 (PANSS) と執行機能 (WCST) の関連性を調査する.
- VEGFがFESのバイオマーカーとして機能するかどうかを判断する.
主な方法:
- FESを持つ32人の若者と35人の健康な対照群を登録した.
- 酵素関連免疫吸収検査 (ELISA) を用いてVEGFを測定した.
- 臨床症状はポジティブ・ネガティブ・シンドローム・スケール (PANSS) で,実行機能はウィスコンシン・カード・ソートリング・テスト (WCST) で評価された.
主要な成果:
- FESを患った若者は,対照群と比較して血清のVEGF濃度が著しく低下した (p=0. 002).
- VEGFレベルは,PANSSの組織不整のスコアと負の相関関係にある (B=-0.12,p=0.002).
- VEGFレベルは,PANSSの感情的苦痛スコアと正の相関関係にある (B=0.17,p=0.035).
- VEGF濃度とWCSTのパフォーマンスとの間に有意な関連性は見つかりませんでした.
結論:
- 血清VEGFの低下は,若者におけるFESの潜在的なバイオマーカーである可能性があります.
- VEGFレベルは統合失調症の病理学的側面を反映しているようで, 組織的混乱や感情的苦痛を含む.
- FESにおけるVEGFのメカニズム的役割とその治療的可能性を明らかにするために,さらなる研究が必要である.

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.

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...

Negative and Cognitive Symptoms of Schizophrenia
118
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

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...
