まとめ
血清の神経繊維のレベルは,多発性硬化症 (MS) の早期認知機能低下を示す可能性があります. より高効率の疾患修飾療法 (DMT) は,MS患者の認知機能低下から保護する見込みを示しています.
科学分野:
- 神経免疫学 神経免疫学とは
- 神経学 神経学とは
- 神経科学は神経科学である.
背景:
- 認知機能障害 (CI) は多発性硬化症 (MS) で一般的であり,疾患の初期に患者に影響を及ぼします.
- CIの早期発見とモニタリングは,さらなる認知機能低下を予防し,治療戦略を導くために重要である.
研究 の 目的:
- 多発性硬化症 (PwMS) の患者における認知機能低下と神経繊維光鎖 (NfL) レベルとの関連を調査する.
- 認知機能の低下,障害の測定,およびPwMSにおけるさまざまな種類の疾患修正治療 (DMT) の間の関係を調査する.
主な方法:
- 64人のPwMSと14人の健康な対照群を対象とした前向きな研究.
- 脳脊髄液 (CSF) と血清におけるNfLレベルを測定する.
- MSのための簡潔な国際認知評価 (BICAMS) を使用した認知評価と,ベースラインと12ヶ月のフォローアップでEDSS,9-HPT,T25FWTを使用した障害評価.
主要な成果:
- PwMSは,対照群と比較して,血清NfL (sNfL) の基準値が高く,フォローアップ時に正常化しました.
- Symbol Digit Modalities Test (SDMT) は,PwMSのフォローアップで著しく減少した唯一のBICAMSサブテストでした.
- ベースラインおよびフォローアップのsNfLレベルはSDMTの減少を予測し,プラットフォームのDMTは,より高効率のDMTと比較してSDMTの減少のリスクの増加と関連していました.
結論:
- 血清NfLは,MSにおける早期認知機能低下のバイオマーカーとしての可能性を示しています.
- MS管理の初期により高効率のDMTを導入することは,認知機能低下に対する保護を提供することができます.

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.
Alzheimer's Disease: Overview
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 and tau...

Alzheimer's Disease: Treatment
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...
Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
