connections, new synapses, and the more you learn the more backup cognitive reserve you ve got. there was a great study, a nun study, where these nuns were followed for two decades, older age, 75 and older, and when they died their brains were donated for autopsy. one of the shocking things that came out of the study is that some of the brains, which upon autopsy looks like clear alzheimer s pathology. it had plaques and tangles and brain shrinkage from neuron to cell death, the scientists looking at this said clearly these nuns had alzheimer s and when you go back to the data and look at how they lived, they weren t diagnosed with alzheimer s. they had no cognitive memory problems. no symptoms. why? and we think it s because they had a high level these particular nuns had a high level of cognitive reserve. what does that mean? they were highly educated, had a high degree of literacy. they were always learning new things, and so we think that they had they just had han ab
prevent the biological advancement of the disease. one of those more alarming areas of research have to do with sleep. so in deep sleep our cells in our brain clear away metabolic waste that accumulates in those synapses while we are being awake. one of the thij things it cleay is amyloid beta. what happens if you don t get a good night of sleep? the cells didn t get a chance to clear everything away so you start with amyloid buildup. over time that can lead you to that tipping point. heart disease, heart health. we know through lots of studies that high blood pressure, high cholesterol, obesity, diabetes and smoking increase the risk of getting alzheimer s.
there s are lifestyle changes that can help prevent the biological advancement of the disease. one of the alarming new areas of research has to do with sleep. so in deep sleep, in slow-wave sleep, our glial cells clear away metabolic waste that accumulates in those synapses while we were in the business of being awake. and one of the things it clears away is the bad guy that starts the alzheimer s disease. but what happens if you don t get a good night s sleep? whoo happ what happens in you debriev yourself of that sleep? the cells didn t get a chance to clear everything away so you start the next day with some buildup. over time, that can lead you to that tipping point. heart disease, heart health. we know through lots of studies that high blood pressure, high cholesterol, obesity, diabetes,
