Area of Science:

  • Ophthalmology
  • Neurology
  • Biomarkers

Background:

  • Alzheimer disease (AD) is a progressive neurodegenerative disorder and a primary cause of dementia in the elderly.
  • Early-stage AD often presents with subtle or absent clinical symptoms, complicating diagnosis despite existing neuropathology.
  • Noninvasive diagnostic and prognostic methods for AD are crucial.

Purpose of the Study:

  • To review Alzheimer disease (AD) and its associated markers.
  • To explore the potential presence of AD markers in the eye lens.
  • To discuss the link between cataract and AD for improved early diagnosis.

Main Methods:

  • Literature review of studies on Alzheimer disease.
  • Analysis of research linking β-amyloid (Aβ) to both AD and cataract.
Keywords:
Alzheimer diseaseAmyloid beta-peptidesCataract

Related Experiment Videos

  • Examination of potential lens biomarkers for AD.

    • Main Results:

    • β-amyloid (Aβ) has been identified as a potential link between Alzheimer disease and cataract.
    • The eye lens may harbor markers associated with AD.
    • Cataract may serve as an indicator for AD.

    Conclusions:

    • The eye lens presents a potential site for identifying biomarkers for Alzheimer disease.
    • Investigating lens changes and cataract may offer a noninvasive approach for early AD diagnosis and prognosis.
