精神スペクトラム障害における認知機能:現状と臨床的意義
Tijdschrift voor psychiatrie
|January 20, 2026
まとめ
精神スペクトラム障害(PSS)における認知機能障害は一般的であるが、見過ごされがちである。認知リハビリテーション(CR)は、PSS患者の認知機能と日常生活の改善に効果を示す。
科学分野:
- 神経科学
- 精神医学
- 認知心理学
背景:
- 認知機能障害は、精神スペクトラム障害(PSS)の約70%の人々に影響を与え、日常生活に著しい影響を与えます。
- これらの障害は臨床的に見過ごされがちであり、DSM分類に特異性がありません。
- 認知障害は、歴史的に早発性痴呆の概念の中心でした。
研究 の 目的:
- 精神スペクトラム障害における認知機能に関する包括的な文献レビューを提供すること。
- PSSにおける認知機能障害の有病率、経過、および影響を強調すること。
- 現在の治療戦略とその有効性をレビューすること。
主な方法:
- PSSにおける認知に関する既存の文献の体系的なレビューと要約。
- 認知機能障害に関連する神経画像および遺伝子研究の結果の分析。
- 薬理学的治療および認知リハビリテーションの有効性の評価。
主要な成果:
- PSS患者は、一般人口と比較して、ほとんどの認知領域で低いスコアを示し、患者間にはかなりのばらつきがあります。
- PSSに特有の単一の認知障害はありません。最初の精神病エピソード後のスクリーニング(例:MATRICSバッテリー)が推奨されます。
- 認知リハビリテーション(CR)は有益な効果を示しますが、薬理学的治療はわずかな改善しか提供しません。
結論:
- 体系的な認知スクリーニングとCRをPSS治療計画に統合することで、患者の機能と生活の質を向上させることができます。
- 推奨にもかかわらず、認知リハビリテーションの実際的な利用可能性は依然として限られています。
- PSSにおける認知障害に対処するためには、さらなる研究と実装戦略が必要です。

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...

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

The Electromagnetic Spectrum

The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

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...

IR Spectrum

When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...
