Clinical Scorecard: Associations of Choroid Plexus Enlargement, White Matter Hyperintensities, and Cognitive Function in Individuals with Type 2 Diabetes Mellitus Mediated by Free Water

At a Glance

CategoryDetail
Condition
Key MechanismsChoroid plexus enlargement, glymphatic-related brain fluid changes, white matter hyperintensities
Target Population
Care Setting

Key Highlights

  • T2DM patients showed larger choroid plexus volume and greater white matter hyperintensities compared to healthy controls.
  • Free water fraction and periventricular white matter hyperintensity volume were linked to cognitive performance.
  • Indirect effects were observed through free water in the associations between choroid plexus volume, white matter hyperintensities, and cognitive function.

Guideline-Based Recommendations

Diagnosis

  • Utilize brain MRI to assess choroid plexus volume and white matter hyperintensities in T2DM patients.

Management

  • Monitor cognitive performance in T2DM patients.

Monitoring & Follow-up

  • Regular assessment of glymphatic-related MRI markers may provide insights into cognitive decline.

Risks

  • Increased risk of cognitive impairment associated with greater white matter hyperintensities and choroid plexus enlargement.

Patient & Prescribing Data

104 patients diagnosed with Type 2 Diabetes Mellitus and 56 healthy controls

Cognitive performance in T2DM may be influenced by brain fluid dynamics and structural brain changes.
