まとめ
早期発症した統合失調症 (EOS) は,異なる皮質の再編成パターンを示し,結合領域の厚さが減少し,感覚運動領域は増加する. これらの変化は特定の遺伝子発現に関連しており,他の神経発達障害との共通の起源を示唆しています.
科学分野:
- 神経科学
- 発達精神科
- 遺伝学
背景:
- 統合失調症の病理的な障害は 脳のコネクトームに広がる可能性があります
- 統合失調症の発症における 早期の皮質の再編成を理解することは 原因を特定するのに不可欠です
研究 の 目的:
- 神経発達モデルとして早期発症性統合失調症 (EOS) を用いて統合失調症の早期病理的起源を調査する.
- 機能的・構造的なコネクトームがEOSにおける早期の皮質の再編成をどのように導いているかを探求する.
主な方法:
- 前例の抗精神病患者95人 (7~17歳) と,典型的に発達した99人の対照群を比較した.
- 皮質の厚さを分析し,変化のエピセンターを特定するために,規範的なコネクトミクスモデルを使用しました.
- 死亡後の6人の献血者からのトランスクリプトミックのデータを エピセンターの発見と相関させました
主要な成果:
- EOSの患者は,特にアソシエーション領域 (言語,感情,認知) で,広範囲に広がった皮質の厚さの減少を示し,主皮質領域 (感覚運動) で増加した.
- トランスクリプトミア分析では,オリゴデンドロサイトに関連した変化がセンソモーター中心部で,刺激/阻害性ニューロン発現がアソシエーション中心部で明らかになった.
- 震源地図は神経発達障害と人間の加速領域遺伝子との相関関係がある.
結論:
- 統合失調症の病理的起源は 神経発達に根ざし 早期発症の症例では 皮質の再編成の明確なパターンがあります
- 発見は統合失調症と 他の神経発達障害の間の 共通の遺伝的決定因子を示唆しています
- この研究は統合失調症の早期病理的増殖を誘導する コネクトームの役割を強調しています

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...

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.

01:21Association Areas of the Cortex
6.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

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...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms

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...
