Dementia

482
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Alzheimer's Disease: Treatment

744
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...

Alzheimer's Disease: Overview

1.6K
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: Overview

1.7K
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...

科学分野:

  • 老年学; 神経科学; 公衆衛生

背景:

  • アルツハイマー病および関連認知症(AD/ADRD)は、ヒスパニック/ラテン系成人を含む過小評価されている集団に不均衡に影響を与える。; この人口集団における認知的および機能的変化は、十分に研究されていない。; COMPADRE-CART研究は、ヒスパニック/ラテン系成人における健康と活動を監視するために、自宅ベースのテクノロジーを利用している。

研究 の 目的:

  • 認知的に健常(CU)なヒスパニック/ラテン系成人および軽度認知障害(MCI)のあるヒスパニック/ラテン系成人における自宅ベースの活動パターンの違いを調査すること。; ベースラインにおけるCU群とMCI群間の週次デジタル調査の完了指標および回答を比較すること。

主な方法:

  • 南テキサスから募集した62歳以上のヒスパニック/ラテン系参加者。; 活動監視のために、部屋のセンサーや手首装着型アクチグラフを含む自宅ベースのテクノロジーを利用した。; 週次のデジタル調査(Qualtrics)および臨床評価(UDS 3)を通じて自己申告データを収集した。

主要な成果:

  • CU群とMCI群の間で、日常生活活動パターン(歩数、睡眠、外出時間)に有意な差は認められなかった。; MCI患者は週あたりの調査完了率が低く、完了に要する時間が長かった。; MCI群は痛みのレベルが高いと報告したが、その他の自己申告による健康イベントは群間で同様であった。

結論:

  • 週次のデジタルアンケート指標は、MCIのあるヒスパニック/ラテン系成人における微妙な機能差を検出する可能性を示す。; これらのデジタル指標の縦断的監視は、将来の認知低下を予測する可能性がある。
