Brainy bitter

A recent study (1) suggests a novel way to control blood sugar and more generally, reduce the complications arising from type II diabetes, a disease responsible for over half of healthcare costs around the world. Meat eating homo-sapiens found agriculture recently and an overdose of carbs now threaten to create a negative slope to their expected lifespan for the first time in human history. As millions around the world take to processed food and sugar-infused drinks as their economies improve, the world is moving closer to a healthcare precipice. They lose feeling in their feet, sight, movement and even reach amputations of limbs, not to mention the complete loss of life due to heart attacks and strokes, due to a simple condition - excess sugar and insulin in their system. The miracle of insulin has kept them going beyond expiry but all attempts at delivering the drug in easier ways, have failed.

Now, the intriguing new study shows how the brain could play an important part in the regulation of glucose (1) in the body. Dopamine release induced by deep brain electrical stimulation seems to improve insulin sensitivity, the loss of which portends the arrival of the wretched disease. Loss or lack of production of dopamine appears to reduce insulin sensitivity, likely leading to type II diabetes over time in non-diabetics. The pancreas, which is responsible for optimally producing insulin to break down the bad intake is totally within the control of the brain that appears to behave differently based on the amount of dopamine it produces. The experiments explained in the study appear to support that neuronal activity in the forebrain could improve insulin sensitivity with beneficial effects on humans, either suffering from or tending toward the well-understood condition. 

An active and stimulated brain could be the least invasive intervention to most diseases.
