Previous studies have demonstrated that even 1 episode can induce hypoglycemia-associated autonomic failure and subsequent recurrent hypoglycemia ( 6, 7). Hypoglycemic episodes due to tight glycemic control using insulin or other hypoglycemic agents occur in approximately 25%–30% of patients with diabetes ( 4, 5). ![]() Nevertheless, determinants of accelerated cognitive decline in patients with diabetes with genetic susceptibility to AD are less clear because glucose dyshomeostasis is complex and can range from chronic hyperglycemia to treatment-induced recurrent hypoglycemia or be combined with hypertension and cardiovascular complications. Given that the symptoms and pathology of late-onset sporadic AD develop over many years or even decades, control of risk factors is essential to delay or prevent the progression of severe cognitive deficits. Efficient therapies remain elusive despite intensive research on treatments for AD over the past few decades. Clinically, AD may be early-onset familial AD or late-onset sporadic AD, with the latter closely associated with genetic and metabolic risk factors, such as diabetes, hypertension, obesity, smoking, and depression, that significantly exacerbate AD-type pathologies and promote disease progression ( 1– 3). Avoiding RH is essential for glycemic control in patients with diabetes, and TRPC6/GLUT3 represents potent targets for delaying the onset of dementia in patients with diabetes.Īlzheimer’s disease (AD) is the most common form of dementia and is characterized by progressive deficits in memory and cognitive function. Taken together, RH impairs brain GLUT3-mediated glucose uptake and further provokes neuronal mitochondrial dysfunction by inhibiting TRPC6 expression, which then accelerates progression of cognitive deficits in diabetic APP/PS1 mice. ![]() Activation of the transient receptor potential channel 6 (TRPC6) increased GLUT3-mediated glucose uptake in the brain and alleviated RH-induced cognitive deficits, and inactivation of the Ca 2+/AMPK pathway was responsible for TRPC6-induced GLUT3 inhibition. Overexpression of GLUT3, specifically in the dentate gyrus (DG) area of the hippocampus, enhanced mitochondrial function and improved cognitive deficits. Glucose transporter 3–mediated (GLUT3-mediated) neuronal glucose uptake was not significantly altered under hyperglycemia but was markedly reduced by RH, which induced excessive mitochondrial fission in the hippocampus. Here, we report that insulin-controlled hyperglycemia slightly aggravated AD-type pathologies and cognitive impairment however, RH significantly increased neuronal hyperactivity and accelerated the progression of cognitive deficits in streptozotocin-induced (STZ-induced) diabetic APP/PS1 mice. Severe hypoglycemia is strongly associated with dementia however, the effects of recurrent moderate hypoglycemia (RH) on the progression of cognitive deficits in patients with diabetes with genetic susceptibility to AD remain unclear.
