    Diabetes is linked to neurological complications, particularly peripheral neuropathy (PN) and dementia, as noted in the 2024 Lancet Commission report.

  • 2

    Metabolic syndrome (MetS) encompasses disorders like prediabetes, T2D, and obesity, contributing to neurodegeneration manifesting as PN and dementia.

  • 3

    PN typically presents as symmetrical, length-dependent nerve injury, often described as a 'stocking–glove' pattern, affecting the feet and hands.

  • 4

    Cognitive impairment (CI) spans a spectrum from subtle dysfunction to advanced dementias, with a significant global burden projected to rise by 2050.

  • 5

    Both PN and CI share metabolic risk factors from MetS, including elevated fasting glucose, obesity, dyslipidemia, and hypertension.
