まとめ
進行性超核性麻痺 (PSP) の患者は,パーキンソン病よりも大きな実行アノソグノシアを示します.
科学分野:
- 神経科学は神経科学である.
- 認知心理学とは,認知心理学である.
- 神経学 神経学とは
背景:
- エグゼクティブ機能の欠陥は,パーキンソン病 (PD) と進行性超核性麻痺 (PSP) で一般的です.
- エグゼクティブ・アノソグノシア,すなわち,エグゼクティブ・機能の欠陥を認識したり報告したりできない状態は,これらの状態を有する一部の患者に影響を及ぼします.
- エグゼクティブアノソグノシアの理解は,神経変性疾患の正確な評価と治療に不可欠です.
研究 の 目的:
- PSPとPDと診断された患者のエグゼクティブアノソグノシアを比較的に分析する.
- 客観的な実行機能の評価と主観的な患者/情報提供者の報告の間の不一致を評価する.
主な方法:
- 執行機能の客観的な神経心理学的評価 (ONA-CEF) と,患者および情報提供者によって報告されたスケール (DEX-R,AAPI-CP) の比較.
- 客観的な業績と主観的な認識の間のギャップを定量化するために計算された不一致指数.
- ONA-CEFのセマンティック/フォネミック・ヴェルバルの流暢性とウィスコンシン・カードソートテストのサブスコアを活用した.
主要な成果:
- PSPの患者は,PDの患者と比較して,エグゼクティブアノソグノシア (より大きな負の不一致) が著しく増加した.
- 情報提供者の報告は不一致を部分的に軽減したが,PSPにおける報告不足を排除することはできなかった.
- 患者によって報告された困難 (DEX-R) は,うつ病の症状と相関しており,客観的な執行機能ではありません.
結論:
- エグゼクティブアノソグノシアはPSPのマーカーとして機能し,臨床試験における客観的な評価の必要性を強調しています.
- PSPにおける患者による報告結果は,実際の障害ではなく,気分の影響を受け,その妥当性に異議を唱える.
- 客観的な神経心理学的テストは,PSPおよび同様の神経学的状態における執行機能の正確な評価に不可欠です.

Parkinson's Disease: Overview
2.1K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment
1.2K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Alzheimer's Disease: Overview
1.8K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Visual Agnosia
1.3K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
