Neuroglycopenia is a shortage of glucose (glycopenia) in the brain, usually due to hypoglycemia. Glycopenia affects the function of neurons, and alters brain function and behavior. Prolonged or recurrent neuroglycopenia can result in loss of consciousness, damage to the brain, and eventual death. [1] [2] [3]
Through digestion, dietary carbohydrates are broken down and converted into glucose, which is the sole energy source for the brain. [5] [8] [11] Optimal brain function relies on adequate carbohydrate consumption, as carbohydrates provide the quickest source of glucose for the brain. [12]
Changes in brain activity are closely coupled with changes in blood flow in those areas, and knowing this has proved useful in mapping brain functions in humans. The measurement of haemodynamic response, in a clinical setting, can be used to create images of the brain in which especially active and inactive regions are shown as distinct from ...
Apr. 12—Type 1 diabetes patients showed slower and less accurate cognitive responses when their blood sugar levels were too low or high, according to a study that gives another reason for ...
“Understanding that information with a continuous glucose monitor (CGM) as well as all the factors that may affect you as an individual (genetics, activity, current health, weight, hydration ...
The cells of the neurovascular unit also make up the blood–brain barrier (BBB), which plays an important role in maintaining the microenvironment of the brain. [11] In addition to regulating the exit and entrance of blood, the blood–brain barrier also filters toxins that may cause inflammation, injury, and disease. [12]
Having less functional GLUT1 protein reduces the amount of glucose available to brain cells, which affects brain development and function. [14] Because glucose is the primary source of fuel for the brain, patients with GLUT1 deficiency have insufficient cellular energy to permit normal brain growth and function. [8]
People with high blood pressure who slept for shorter durations were more likely to show poor cognitive function and increased levels of markers of brain aging and injury, a new study has found.
