Abstract:​

​​

This article is a literary review of Type 1 Diabetes Mellitus (T1DM) and its impact on the brain. T1DM is a chronic autoimmune condition characterized by the destruction of pancreatic beta cells, leading to insulin deficiency. While the metabolic effects of T1DM are well known, its impact on brain function and structure remains under-researched. This review examines the neurological and cognitive implications of T1DM, stressing the disruption of glucose metabolism and its effects on the brain, such as blood-brain barrier damage, oxidative stress, and inflammation. Neuroimaging studies reveal structural changes, including reduced gray matter volume and altered white matter integrity, which correlate with cognitive impairments like reduced executive functions and memory issues. These changes are particularly concerning for juveniles, as brain development during adolescence is critical. Effective management of T1DM is essential to reduce these neurological complications. Recommendations include implementing continuous glucose monitoring, early cognitive screening, and personalized treatment plans. Further research is necessary to explain the mechanisms linking T1DM to brain alterations and to explore neuroprotective therapies.
