Diabetic peripheral neuropathy associated with cognitive decline in type 2 diabetes patients: Study

USA: A recent study has highlighted the association between diabetic peripheral neuropathy (DPN) with lower cognitive performance in people with type 2 diabetes (T2D) of f <10 years of known duration. DPN was found to be inversely and significantly associated with measures of immediate recall and processing speed. The study was published in the Journal of Diabetes and its Complications on 15 September 2021.
There is a lack of studies examining measures of cognition are related to DPN presence and/or cardiovascular autonomic neuropathy (CAN). Also, data regarding actors potentially explaining such associations are lacking. To fill this knowledge gap, Joshua I.Barzilay, Emory University School of Medicine, Atlanta, GA, USA, and colleagues recruited participants from the Glycemia Reduction Approaches in Diabetes Study (GRADE) that examined 5047 middle-aged people with type 2 diabetes of <10 years of known duration.
Using Spanish English Verbal Learning Test, the researchers assessed verbal learning and immediate and delayed recall (memory). Frontal executive function and processing speed were assessed with Digit Symbol Substitution Test; ability to concentrate and organize data with word and animal fluency test. DPN was assessed with the Michigan Neuropathy Screening Instrument and CAN by indices of heart rate variability (standard deviation of normal beat to beat variation [SDNN] and root mean square of successive differences [RMSSD]).
The research yielded the following findings:
- DPN was significantly inversely related to measures of immediate recall and processing speed.
- The percent of cognitive variation explained by DPN was small.
- Tests of CAN had an inconsistent or absent association with measures of cognition.
- Higher waist circumference and urine albumin creatinine (UACR) levels were the strongest correlates in the relationship between DPN and cognitive impairment.
"Our findings revealed that DPN, but not CAN, was cross-sectionally associated with lower performance in measures of cognition in people with type 2 diabetes of <10 years of known duration," wrote the authors. "Greater waist circumference and UACR were important variables in this association.:
"Further study is warranted to evaluate the mechanism underlying the association between diabetic peripheral neuropathy and cognition," they concluded.
