Twenty percent of all the glucose in your body is used by the brain, and as you go from being normal to having mild cognitive impairment, which is a precursor for Alzheimer's, all the way to Alzheimer's disease, then there are areas of the brain that stop using glucose. They shut down. They turn off. And indeed, what we see is that these areas in red around the outside ribbon of the brain are progressively getting more and more blue until they shut down completely.
20% de toda la glucosa en tu cuerpo es utilizada por tu cerebro, y mientras pasas de ser alguien normal a tener un impedimento cognitivo menor, que es un precursor del Alzheimer, hasta tener Alzheimer, habrá áreas del cerebro que dejarán de usar glucosa. Se apagan. Y en efecto, lo que observamos es que estas áreas en rojo alrededor de la franja exterior del cerebro se vuelven cada vez más y más azules hasta que se apagan por completo.
