Chronic hyperglycemia impairs hippocampal neurogenesis and memory in an Alzheimer’s disease mouse model

During aging, lifestyle-related factors shape the brain's response to insults and modulate the progression of neurodegenerative pathologies such as Alzheimer's disease (AD). This is the case for chronic hyperglycemia associated with type 2 diabetes, which reduces the brain's ability to handle the neurodegenerative burden associated with AD. However, the mechanisms behind the effects of chronic hyperglycemia in the context of AD are not fully...
