Insights

Alzheimer

Area of Science:

  • Neurology
  • Neuroimaging
  • Vascular Biology

Background:

  • Alzheimer's disease (AD) is increasingly recognized as a complex, multifactorial condition.
  • Vascular dysfunction is a significant, early contributor to AD pathophysiology.
  • The current AD Research Framework focuses on amyloid, tau, and neuronal injury.

Purpose of the Study:

  • To highlight the role of vascular dysfunction in Alzheimer's disease.
  • To propose the integration of vascular imaging biomarkers into the AD Research Framework.
  • To improve understanding and treatment of AD by incorporating vascular factors.

Main Methods:

  • Review of evidence linking vascular dysfunction to AD.
  • Examination of neuroimaging techniques for assessing vascular changes (e.g., blood-brain barrier integrity, cerebral blood flow).
  • Discussion of established vascular imaging biomarkers for small vessel disease.

Main Results:

  • Vascular dysfunction is an early and critical component of AD.
  • Neuroimaging can effectively evaluate vascular contributions to AD.
  • Existing biomarkers for small vessel disease are well-characterized and readily applicable.

Conclusions:

  • Vascular factors are crucial for a comprehensive understanding of Alzheimer's disease.
  • Incorporating vascular imaging biomarkers into the AD Research Framework is recommended.
  • This integration can enhance AD diagnosis, treatment, and research efforts.

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...

Dementia

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 Disease l: Introduction01:29

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...
Dementia l: Introduction01:22

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
