Key result
Age and cardiopathology were inversely related to cognitive performance in elderly patients with diabetes, while years of schooling and regular physical activity appeared as neuroprotective factors.
Why the study?
Diabetes Mellitus is associated with cognitive impairment, but the impact of clinical and sociodemographic factors on cognitive processes in elderly diabetic patients is not fully understood.
Do clinical and sociodemographic factors impact cognitive performance in elderly patients with diabetes?

Do clinical and sociodemographic factors impact cognitive performance in elderly patients with diabetes?
In elderly patients with diabetes, age and cardiopathology are associated with worse cognitive performance, whereas education and physical activity are protective.
May inform cognitive risk stratification in elderly diabetics with heart disease; hypothesis-generating for education and activity as protective factors.
The aim of this study is to analyze the potential impact of factors (clinical and demographic variables and comorbidities) associated with Diabetes Mellitus (DM) on certain mental processes related to cognitive impairment, with special attention to the analysis of parameters that define processing speed and executive function. Neuropsychological examination of elderly Spanish patients (N = 59, 33 females, M age 70.98 years) diagnosed with DM, in addition to application of an ad hoc questionnaire to collect information on comorbidities and other relevant demographic variables. Based on a cross-sectional design, correlational analysis was carried out. Cognitive performance showed an inverse relationship to age and cardiopathology while years of schooling and regular physical activity appeared as neuroprotective factors. DM is an illness which, linked to other variables, can be regarded as a risk factor for the development of cognitive impairment. Certain factors (physical activity and cognitive stimulation) have the potential to mitigate this tendency. There is a need to further our understanding of the neurobiological mechanisms involved.

Barroso et al. (2015) conducted a cross-sectional in Diabetes Mellitus (n=59). Clinical and sociodemographic factors was evaluated on Cognitive performance (processing speed and executive function). Age and cardiopathology were inversely related to cognitive performance in elderly patients with diabetes, while years of schooling and regular physical activity appeared as neuroprotective factors.
