The study evaluates how diabetes-related factors influence spatial navigation using the virtual Morris water maze task.

Visible-stage motor-related outcomes show sex-specific group differences, while hidden-stage learning and memory outcomes are comparable.

We investigated the influence of diabetes-related factors on their spatial navigation performance.  \nMethods Spatial navigation performance on the virtual Morris water maze task (vMWMT) was evaluated in adolescents with type 1 diabetes and compared with that of healthy control adolescents of similar age and sex. Collected data on diabetesrelated variables included disease duration, diabetic ketoacidosis (DKA) at diagnosis and continuous glucose monitoring (CGM) metrics during the 2 weeks preceding the assessment, with focus upon nocturnal values measured during the night before testing. Time to first move, time to platform and path length were measured in visible and hidden platform vMWMT stages.  \nResults The 74 study participants (age 15.6 ± 3.1 years, 45 boys) with type 1 diabetes demonstrated sex-specific patterns of spatial navigation, comparable with those observed in the healthy control group. Both the boys and girls had longer time to first move than the control groups in the visible platform stage, which assessed motor control (p=0.036 and p=0.002, respectively). Test outcomes did not differ between the participants with and without type 1 diabetes in the hidden platform stages, which assessed spatial learning and memory. However, linear regression models adjusted for sex, age and DKA at diagnosis found that diabetes duration (β=0 .464, p\u003C0 .001) independently predicted longer time to platform (R2=0 .396, p=0 .003), while nocturnal time spent in marked hypoglycaemia (β=0 .397, p=0 .002) predicted longer path length (R2=0 .206, p=0 .017) . Conclusions/interpretation Spatial navigation performance in adolescents with type 1 diabetes is influenced by both disease duration and recent glycaemic control. Glycaemic excursions, especially during the night, were shown to impair performance.  \nKeywords Cognitive function · Glycaemic management · Spatial navigation · Type 1 diabetes · Virtual Morris water maze  \nAbbreviations  \nAID Automated insulin delivery  \nCGM Continuous glucose monitoring  \nDKA Diabetic ketoacidosis  \nGMI Glucose management indicator  \nMDI Multiple daily injections  \nSEP Socioeconomic position  \nvMWMT Virtual Morris water maze task  \n* Avivit Brener  \n[avivitbrener@tauex.tau.ac.il](avivitbrener@tauex.tau.ac.il); [avivitb@tlvmc.gov.il](avivitb@tlvmc.gov.il)  \n1 Gray Faculty of Medical and Health Sciences, Tel Aviv University, Tel Aviv, Israel  \n2 The Institute of Pediatric Endocrinology, Diabetes and Metabolism,‘Dana-Dwek’ Children’s Hospital, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel  \nIntroduction  \nAccumulating evidence points to mild-to-moderate cognitive deficits and compromised academic achievement in adolescents with type 1 diabetes [1, 2] . In individuals with type 1 diabetes, extreme glycaemic fluctuations, particularly hypoglycaemia and, to a lesser extent, hyperglycaemia, may be associated with declines in cognitive functions [3, 4]. Distinct central neuropathic alterations in the hippocampus, a region critical  \nfor memory formation, attention and spatial navigation, were reported in individuals with type 1 diabetes [5]. Rodent models of diabetes revealed hippocampal electrophysiological abnormalities and related deficits in learning, memory and cognition [6] .
