GLUCOSE DECIDES CONSCIOUSNESS

Scientists from University of Copenhagen and Yale University have done a research on the patients who are in coma. The Positron Emission Tomography (PET) scanning type is used by the researches to predict whether a patient will be free from coma or not. They analyze the patient’s condition on measuring with the camera that detects emission from a radioactive glucose that is given to the brains.

Brain gets the energy from the glucose which can be referred as brain food and by observing glucose metabolism in the brain can decide how actively a brain was by the researchers.

Shining Up the Brain:

On studying 131 patients of different cases like patients who were in deep coma as well as patients who respond to stimuli are to be considered as comatose. These patients were under observation for a year and 42 percent of cerebral energy is necessary to return a patient into consciousness. The 42 percent can be referred as the threshold level and the patient who is below this level would die or remain in coma. Out of many patients one of them was in more responsive state. Remaining was totally unresponsive but had higher levels of brain activity i.e. out of 11 patients, 8 recovered.

This test would help family and doctors who could assume a rough time for recovery of the patient. It also determines whether the person would die.

Bond of Glucose and Consciousness:

Level of consciousness of a patient depends upon the brains energy consumption which is obtained by the glucose. Researches also observed differences between the patients who have high metabolism and low metabolism energy levels in the brain. Further research is done on the patients beyond one year that how much long they would stay in coma and researchers work would be reused by the other researchers.
