Abstract

Insights

White matter hyperintensity (WMH) is linked to amnestic mild cognitive impairment (MCI), while brain infarcts are associated with non-amnestic MCI. Further research is needed to understand WMH

Area of Science:

  • Neurology
  • Neuroimaging
  • Cognitive Science

Background:

  • Cerebrovascular disease (CVD) is a potential contributor to mild cognitive impairment (MCI).
  • Understanding the neuroimaging correlates of MCI is crucial for early detection and intervention.
  • Community-based studies provide valuable insights into the prevalence and risk factors of cognitive decline.

Purpose of the Study:

  • To investigate the relationship between white matter hyperintensity (WMH) volume and infarcts on brain MRI and mild cognitive impairment (MCI).
  • To differentiate the associations of WMH and infarcts with amnestic versus non-amnestic MCI subtypes.

Main Methods:

  • Brain MRI scans were analyzed for 679 elderly individuals without dementia.
  • White matter hyperintensity (WMH) volume and infarcts were quantified using standardized research methodologies.
  • Logistic regression models were employed to assess the association between WMH, infarcts, and prevalent MCI, with adjustments for relevant demographic and genetic factors.

Main Results:

  • White matter hyperintensities (WMH) showed a significant association with amnestic MCI (OR=1.9), but not non-amnestic MCI.
  • Brain infarcts were more strongly associated with non-amnestic MCI (OR=2.7) compared to amnestic MCI (OR=1.4).
  • Further analyses indicated WMH related to memory, while infarcts related to non-amnestic cognitive domains.

Conclusions:

  • White matter hyperintensity (WMH) is a significant neuroimaging marker for amnestic MCI.
  • Brain infarcts are more strongly associated with non-amnestic MCI.
  • The specific role and nature of WMH in amnestic MCI warrant further in-depth investigation.

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...

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...
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's Disease: Overview01:26

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...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
