 Hi, I'm Jason Rosenberg. I'm a neurologist and headache medicine sub-specialist. Fortunately, most of the time when patients come to me worried that they have Alzheimer's, they usually won't have it. And then we have a conversation. How do I keep my brain healthy? What can I do to prevent it? And there are actually some very simple things that can be done to forestall the disease. And in some studies, maybe even reverse early Alzheimer's. So it turns out that physical exercise can improve brain health dramatically. And in some small studies, even reverse the symptoms of early Alzheimer's. Getting good sleep is crucially important. It turns out that new data have shown that during sleep, brain cells actually shrink. And it allows fluid to wash out neurotoxins and all sorts of terrible chemicals that have built up during the day. And if we don't sleep, that doesn't happen. And it turns out that insomnia, sleep apnea and other sleep disorders, even just not giving yourself enough time to sleep, might be a risk factor for Alzheimer's disease. But I tell patients I'm going to partner with them and get them the best answers and the best treatment that I can for really what's the final frontier of the medicine, the mind, the brain.
