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...

251
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

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,...

科学分野:

  • 神経画像
  • 外傷性脳損傷研究
  • 神経変性

背景:

  • 外傷性脳損傷（TBI）後のMRI脳容積の減少は文書化されていますが、多様なサンプルと性別固有の分析が不足しています。
  • 以前の研究では、影響を受ける脳領域にばらつきがあり、性別に基づく違いの調査が限られています。

研究 の 目的:

  • TBIの既往歴とMRIを用いた脳容積との関連を、地域ベースのコホートで調査すること。
  • TBI関連の脳容積減少における性差の可能性を探求すること。

主な方法:

  • Framingham Heart Study Generation-2コホートの横断的分析を実施し、TBI参加者と対照者をマッチングさせました。
  • 海馬および灰白質/白質容積を含む、テント上構造のMRI容積分析を実施しました。
  • 年齢、教育、APOE e4状態などの共変量を調整して、性別を層別化した分析を実施しました。

主要な成果:

  • TBI参加者は対照群と比較して有意に小さい海馬容積を示しました。
  • TBI群では前頭葉灰白質容積の減少傾向が観察されました。
  • TBIの女性は、男性とは異なり、海馬、前頭葉灰白質、および全脳灰白質の容積の有意な減少を示しました。

結論:

  • TBIは、高齢者、特に女性において脳容積の減少と関連しています。
  • TBI後の脳萎縮における性別固有の違いは、神経変性疾患のリスクに影響を与える可能性があります。
  • MRIの軌跡に対するTBIの縦断的影響を調べるために、さらなる研究が必要です。
