Study Suggests Possible Link Between Diabetic Foot Ulcers, Diminished Cognitive Function

Diabetic-Foot-UlcerIt’s well established that diabetic patients with foot ulcers are at an increased risk for amputation; now a recent study suggests these patients may also have impaired cognitive function, making it far more difficult for them to care for foot ulcers or to seek care when symptoms develop or progress. 

Conducted by researchers at Ben-Gurio
n University of the Negev in Israel, the study compared cognitive function between two groups of patients with diabetes – one group of 99 patients who also had foot ulcers and one group of patients without foot ulcers. Both groups of patients underwent comprehensive neuropsychological testing and cognitive evaluation using tests to assess executive function, memory, attention, reaction times and other cognitive functions. In addition, the authors used scientific methodology to estimate cognitive function prior to developing foot ulcers.

At the conclusion of the study, the authors found the patients who had foot ulcers in addition to diabetes had lower cognitive scores across all cognitive tests compared to those who did not have foot ulcers, even after adjusting for possible influences like smoking and vascular disease. The authors also compared patients’ current cognitive states with estimates of cognitive status prior to developing foot ulcer symptoms and found patients in the foot ulcer group had a significant decline in cognitive functioning between the two states, suggesting a relationship between foot ulcers and a reduction in cognitive ability.

Although the authors noted the study design prohibited drawing a specific cause-effect conclusion, they said the results underscore a paradox that has significant implications for patient who have foot ulcers – namely, that these patients have more challenges when it comes to care, but fewer cognitive resources to effectively manage that care, a combination that can significantly increase the likelihood these patients will require amputations eventually.

“The results imply that ‘[diabetic foot]’ may refer not only to the physical condition but also to a more generalized complex state involving significant cognitive changes as well,” they wrote. The results also highlight the need for ongoing cognitive testing in diabetic patients with foot ulcers, they added.
