Type 2 Diabetes Contributes to Cognitive Decline in Old Age

Strategic Insights

— 1 min read

A recent study conducted in Sweden found that individuals with type 2 diabetes experience accelerated cognitive decline in old age, which may ultimately lead to dementia. Researchers at Goteborg University examined a population-based sample of 274 elderly participants, 36 of whom had diabetes, over a 6-year period. The study used neuropsychological tests to assess cognitive function in areas such as speed, visuospatial ability, and memory. The results showed that, at baseline, individuals with diabetes did not differ significantly from those without diabetes in terms of cognitive function. However, longitudinal analysis revealed that diabetes was a significant predictor of decline in many of the cognitive tests. This study highlights the importance of managing type 2 diabetes to prevent cognitive decline in older adults.

Key Takeaways:

  • The study involved a population-based sample of 274 elderly participants, 36 of whom had type 2 diabetes.
  • Researchers used neuropsychological tests to assess cognitive function in areas such as speed, visuospatial ability, and memory.
  • At baseline, individuals with diabetes did not differ significantly from those without diabetes in terms of cognitive function.
  • Longitudinal analysis revealed that diabetes was a significant predictor of decline in many of the cognitive tests, including speed, visuospatial ability, and memory.
  • The study suggests that type 2 diabetes is associated with accelerated cognitive decline in old age that may result in dementia.
  • Researchers used multilevel modeling (SAS Proc Mixed) to analyze the data.
  • The study was published in the Journal of the International Neuropsychological Society.

Statistics:

  • 274 elderly participants were included in the study.
  • 36 participants had type 2 diabetes, while 238 did not.
  • The participants were 80-93 years of age (mean=82.8 years).
  • The neuropsychological test battery included 6 distinct tests.
  • The Mini Mental Status Examination was used to assess cognitive function.
  • The study used a 6-year longitudinal design.
