まとめ
脂質異常症や高血圧などの代謝症候群の構成要素は、統合失調症患者の認知的欠陥と関連しています。高血圧の管理は、この集団における認知機能と社会的転帰を改善する可能性があります。
科学分野:
- 神経科学
- 精神医学
- 代謝性疾患
背景:
- 認知機能障害は、統合失調症患者(PWS)によく見られる。
- 代謝症候群(MetS)は、PWSにおける認知機能障害を悪化させる可能性がある。
- MetS構成要素と認知機能障害との正確な関連を明確にする必要がある。
研究 の 目的:
- 個々のMetS構成要素とPWSにおける多次元的認知機能障害との関連を調査する。
- 臨床症状と認知機能の関係における代謝指標の媒介的役割を探る。
- 機械学習を用いて、認知転帰に対するMetS構成要素の予測有用性を検証する。
主な方法:
- 臨床的に安定した727人のPWS患者を対象とした多施設共同研究。
- 中国版簡易認知テスト(C-BCT)を用いて認知機能を評価。
- ネットワーク分析、構造方程式モデリング(SEM)、および機械学習を採用した。
主要な成果:
- 脂質異常症(DL)および高血圧(HT)は、認知機能障害と有意な関連があった。
- 2つ以上のMetS構成要素(MetS-2+)を持つ患者は、異なるネットワークパターンを示した。
- DLおよびHTは、臨床症状と認知機能の関係を媒介した。
- 機械学習モデルは、MetS構成要素に基づいて認知次元を効果的に予測した。
結論:
- 特定のMetS構成要素、特にDLおよびHTは、安定したPWSにおける認知機能と複雑に関連している。
- HTの管理は、PWSにおける認知機能の向上と社会的機能の改善のための戦略を提供する可能性がある。
- MetS構成要素は、統合失調症における多次元的認知転帰の重要な予測因子である。

Negative and Cognitive Symptoms of Schizophrenia
564
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,...

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Schizophrenia
957
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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism
227
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Biological Causes of Schizophrenia
601
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.

Abnormal Proliferation
5.2K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
