まとめ
ハンチントン病 (HD) の初期段階には アノソグノシア つまり病気に対する意識の欠如が表れます この発見は,HDの臨床研究で自己報告データを使用する際の注意を促しています.
科学分野:
- 神経科学
- 神経学
- 臨床研究
背景:
- ハンチントン病 (HD) は しばしばアノソグノシア つまり 障害に対する自己認識の欠如を伴います
- HDの進行中のアノソグノシアの正確な発症はよく理解されていません.
研究 の 目的:
- ハンチントン病の患者に アノソグノシアが出現する時期を 判断するためです
- HDの異なる段階におけるアノソグノシアの存在と欠如を評価する.
主な方法:
- アノソグノシアスケールは60人のハンチントン病の遺伝子キャリアとその研究パートナーに投与されました.
- 参加者は,HD統合ステージシステム (HD-ISS),総機能能力 (TFC),CAG-Age-Product (CAP),複合統合ハンチントン病評価スケール (cUHDRS) を用いて層分かれました.
- アノソグノシアは,患者と情報提供者の報告のスコア差 ≥6点で特定されました.
主要な成果:
- HD- ISS ステージ0/1の参加者の18%でアノソグノシアが観察されました.
- 13のTFCスコアを持つ患者の22%がアノソグノシアを示した.
- 臨床試験の適格者の37% (CAPスコア400- 500) とcUHDRS≥14の23%がアノソグノシアの兆候を示した.
結論:
- アノソグノシアは ハンチントン病の初期症状です
- アノソグノシアの早期発症は,HDの臨床試験における自己報告測定値への依存を制限する必要があることを示しています.

Prosopagnosia
251
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...

Visual Agnosia
298
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...

Alzheimer's Disease: Overview
666
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...

Parkinson's Disease: Treatment
376
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.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Parkinson's Disease: Overview
702
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...

Alzheimer's Disease: Treatment
260
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
