Topic: type 1 diabetes

Diabetes is a progressive metabolic disease that can severely damage several organs, including the central nervous system. It has been suggested that diabetes can induce cognitive dysfunction due to expression changes of excitatory neurotransmission mediated by N-methyl-D-aspartate (NMDA) receptors. In addition, diabetes is associated with imbalances in the regulation of intracellular Ca2+, which leads to neuronal damage and, ultimately, a decline in cognitive abilities. Moreover, Type 1 diabetes patients have higher glutamate levels in their brains, which can be used as an early marker of dia

Alzheimer’s disease (AD) is the most common cause of dementia. Despite age being the main risk factor, previous studies have also reported that type 1 diabetes (T1D) may contribute to abnormal tau phosphorylation and worsen cognitive impairment in AD patients. However, the underlying mechanisms are not completely understood. Therefore, we have analyzed the effects of streptozotocin (STZ)-induced T1D in a mouse model of AD (APP/PS1) in terms of metabolic impairment, cortical tau phosphorylation and cognition at 26 weeks of age, when the pathology is fully established. When all groups under stud
