Could We Treat Alzheimer’s with Light and Sound? | Li-Huei Tsai | TED

What if we could use brain waves to treat Alzheimer’s? Professor and neuroscientist Li-Huei Tsai details a promising new approach to artificially stimulate gamma brain waves using light and sound therapy, to increase connectivity and synchrony and delay the onset of this deadly disease. This non-invasive therapy has already been shown to work in mice — now it’s on to human clinical trials, with the potential to usher in a brighter future for everyone.

    Prevention is the best thing to do. Magnesium deficiency can cause of Alzheimer’s, which can happen as early as 30 years old. Up to 80% of people don’t get the RDA for magnesium because there’s less of it in food from ANY developed country. Higher levels of aerobic exercise creates an environment providing the clearance of amyloid beta protein which is another cause of Alzheimer’s.

    I’m all for shock therapy. Not the old massive. Cookoos nest but mild sudden stimulation. Ive taken valium and xanex for decades. But and accidental shock changing a light fixture had a better effect. I guess you can’t go around sticking your fingers into light sockets. But there’s definitely something valid here. Just sayin

    Traders should avoid attempting to predict trend reversals, or even worse, I believe there is more to this market than we currently understand. When people are losing, they don’t endeavor to increase their average. Using expert Clinton Ray’s assistance, I’ve made almost 9.5 btc on a 2 btc Trade capital over the last 8 months. Things could get worse, so make the wise decision. Markets fluctuate in cycles that might span anywhere from a few days to several years. In the case of B -TC, it’s difficult to make a bullish case merely by glancing at the chart. It’s a lot more complicated than some people want you to believe. You can reach Clinton on ͲeIєɠɾαm👉ClinRay👈

    لا يمكنني أن أقدم الإجابة على كافة المسائل المعقدة التي أدت بنا إلى هذه النقطة،

    غير أنني على يقين من أنه يجب علينا من أجل المضي قدما أن نعبر بصراحة عما هو في قلوبنا وعما هو لا يقال إلا خلف الأبواب المغلقة.

    كما يجب أن يتم بذل جهود مستديمة للاستماع إلى بعضنا البعض

    وللتعلم من بعضنا البعض

    وللاحترام المتبادل

    والبحث عن أرضية مشتركة🌎🌏🌍،

    وينص القرآن الكريم على ما يلي
    “اتقوا الله وقولوا قولا سديدا”
    وهذا ما سأحاول – بما في وسعي – أن أفعله،

    وأن أقول الحقيقة بكل تواضع أمام المهمة التي نحن بصددها اعتقادا مني كل الاعتقاد أن المصالح المشتركة بيننا كبشر هي أقوى بكثير من القوى الفاصلة بيننا.

    شكرا لك.

    and # Women♀️do hold 🌎high positions ✓.

    Ladies and gentlemen!

    The question is
    whether we spend that time focused on what pushes us apart?

    or
    whether we commit ourselves to an effort — a sustained effort — to find common ground🌍🌏🌎?.

    to focus on the future we seek for our children – and to
    respect the dignity of all human beings?.

    It’s easier to start wars than to end them.

    It’s easier to blame others than to look inward.

    It’s easier to see what is different about someone
    than to find the things we share.

    But we should choose the right path,
    not just the easy path.

    There’s one rule that lies at the heart of every religion — that we do unto others as we would have them do unto us.

    How about we focus on finding the CAUSE of illnesses and not just focus on treating the SYMPTOMS. Lack of information and communication on prevention and healthy lifestyles is what got us here in the first place!

    • Lucía Medina

      March 8, 2022 at 4:42 pm

      Well, both are necessary, no? Otherwise, the people that already have Alzheimer’s would be left with no solutions. Prevention of the causes + treating the symptoms is the ideal, but the first is harder, because people are not inclined to change their lifestyles unless they go through something hard, like a disease. Say, a well planned plant-based diet is, right now and with the latest research, the safest bet to avoid cognitive and other physical common diseases, like diabetes, high blood pressure, bad cholesterol, etc. But not many people are willing to try it out if they don’t have a serious diagnosis. More education about lifestyle choices that is based on recent studies is needed, preferably since the first years of schooling.

      @Lucía Medina I agree 100%, that’s why I said “not just focus on the symptoms”. The problem is that much more energy is directed towards that, and very little on the prevention. The ideal is to have both for the reason you said – there’s a lot of people that are already sick. But places like TED seem to have become very one-track-minded.
