Alzheimer's Disease: Overview01:26

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...

Imaging Studies IV: Magnetic Resonance Imaging

212
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Genetics
  • Neuroscience
  • Population Health

Background:

  • Understanding genetic ancestry's role in Alzheimer's disease (AD) is crucial for health equity.
  • Genome-Wide Association Studies (GWAS) often use global ancestry, limiting detection of ancestry-specific effects.
  • Local Ancestry Inference (LAI) offers a refined method to identify such effects.

Purpose of the Study:

  • To integrate LAI with regional genetic association analysis on chromosome 19.
  • To identify local ancestry-specific variants associated with hippocampal volume (HV) and cerebrospinal fluid (CSF) Amyloid beta 42 (Aβ42) levels in AD.

Main Methods:

  • Utilized Gnomix for chromosome 19 LAI and Tractor for ancestry-informed GWAS.
  • Analyzed HV (N=1,325) and CSF-Aβ42 (N=282) in the ALFA cohort.
  • Adjusted for age, sex, education, APOE-ε4 status, and LAI-derived components.

Main Results:

  • LAI identified unique single nucleotide polymorphisms (SNPs) associated with HV and CSF-Aβ42, missed by traditional GWAS.
  • Significant SNPs linked to African (HV) and West Asian (Aβ42) ancestries were found in EIF3K and ZNF675 regions.
  • LAI improved SNP resolution within the APOE region, highlighting its cross-ancestry relevance.

Conclusions:

  • LAI is essential for advancing AD genetic research and understanding genetic variation.
  • Findings support LAI's inclusion in future AD studies to promote equity.
  • This approach aids in personalized medicine and equitable genetic discovery for AD.
