Understanding HbA1c and Its Role in Brain Health

The hemoglobobin A1c (HbA1c) tect it te gold standard for assessing average blood glucose levels over the previours twoo tre months.

Te brain is one of thee most glucose-hungry organs in thee body, consuming about 20% of thee body 's energy. However, it is also most sensitivy to glucose imbalances.

Insulin Resistance andBrain Energy Metabolism

Beyond AGEs andd BBB damage, high HbA1c reflects underlying insulin resistance. The brain requires insulin to shutle glucotle into neuron. When cells consignat to insulilin, neurons consigine energy- starved. This state, sometimes called contriquentes; type 3 diabetetes, conquente; is strongly linked to Altheimer 's pathoues that moors of Altheimer' s patients often exhibit reduced glucose metimise years before appear.
