The ROOT CAUSES OF Cognitive Decline & How To PREVENT IT | Mark Hyman

Get my FREE guide 3 Steps to Reverse Aging when you sign up for my weekly health picks 👉 bit.ly/IncreaseHealthspan
Systemic inflammation is an underlying cause of chronic disease. From cardiovascular disease to autoimmunity, cancer, diabetes, and more, inflammation creates immune dysregulation and precedes a slew of other problems.
That’s why many brain symptoms-like brain fog, anxiety, memory loss-can actually be caused by a dysfunction in the immune system. The good news is that this can be reversed.
In this video, I share about my own health journey as well as how the principles of Functional Medicine can be applied to reduce chronic inflammation and cognitive decline.
I also speak with one of the leading experts in Alzheimer’s and dementia research, Dr. Marwan Sabbagh. Dr. Sabbagh discusses the exciting and powerful steps we can all take for a better brain as we age, even when we’re up against poor genes. He shares why genetic testing can help us leverage our lifestyle choices even further, why diet is such a fundamental part of any brain-boosting plan, where environmental toxins come into play, and so much more.

The very fact that you are saying that sugar causes inflammation, makes me wonder why KZbin hasn’t blocked you. I love your knowledge. Thank you, so grateful you are out there. We are listening

I am the only person in my family of 6 who eats clean. Everyone in my family is suffering from major health issues. Sisters, cancer, thyroid, obesity. Brother, obesity heart issues. Father dead from cancer, mother trying but is not completely eating clean. I look younger than everybody in my family. I look younger than people 20 years younger. I eat from my garden, grass fed beef and wild caught salmon.

[@NarlyArly]

I’m trying to go clean. I know how you feel. Sisters thyroid, diabetic migraines. Brother takes female hormones for transgender plus lives on Diet Coke daily, donuts for breakfast, he pops pills for titinitus, migraines. He seems to be brain foggy a lot of the time. Very slow mentally. Sad. Nothing I can do. He’s bent on self diagnosing and getting meds for every ache and pain.

You have to accept that have the right to live their lives as they choose. You may come across as a narcissists if push your agenda on to others and no one likes a narcissist. The best thing you can do is show by example and you are doing that. Somethings are beyond our control. I work in the medical profession. Nurses know better but they have terrible diets. It is their choice.

Thank you Dr. Hyman for all of your great very informative podcasts! I've learned so much from you. I stopped eating all of the "junk" so to speak I was eating prior to listening to your podcasts. You've taught me so much & I will be eternally grateful. My mom has Alzheimer's Disease. Her only sibling, a sister, passed away from Alzheimer's Disease. I don't want to be the third woman in our immediate family to succumb to this cruel disease. You're a real blessing to all of us.

[@karunamayiholisticinc]

Thank you Dr. Hyman for bringing this to light. I grew up on a lot of processed foods along with some whole foods but those whole foods did not have good fats. Even as a vegetarian I never drank Whole fat dairy or butter but had refined oils that my mother used. But mostly processed foods considering I was not given B12 supplements either as a child. But I do agree that policies today support toxicity in environment rather natural whole foods which should contain natural ways of eating Whole fats not fortified products in factories. I see deficiency in me. I do have stress and anxiety issue considering I live in a world that does like to step down on others and play on other people's mind. For this I can do nothing but Karma comes back to all. But I do feel the reason my body is reacting is out of deficiency. Due to stress I am even suspecting to get tested for any signs of Parkinson that I may be prone to in future because of tingling sensation of nerves in my arms and my fingers getting numb often. But I know these signs so early on is a result of toxic and processed industry and our parents not being enlightened enough to give us the right thing or discipline us early on. Anyways, I appreciate you speaking on policies that governs the toxic system. Whether I follow you or not, I definitely appreciate your fearlessness. Thank you.

DR. Hyman, I really appreciate you, and hearing your challenging journey to healing. I so understand the need for going to root cause as it has taken me 4 years to figure out what was wrong with me., mostly on my own. As it turned out my symptoms (neuropathic leg and foot pain) were from Aluminum toxicity. I am currently detoxing it. I found that the cause was from the Aluminum that is in the geo engineering of our skies. There were planes going over my home every day., so the exposure was considerable. At the present time I have assistance in my detoxing by an excellent practitioner similar to you. Thank you for the great work you are doing.

The story about the prisoner brought me to tears. As a healthcare provider that had to stop working because of the effects of multiple chronic viruses, black mold in my blood stream and become overly sensitive to chemicals. It took 8 or more years to finally find a medical group who had been researching causes of FM, CFS etc. Dr Hymans story sadly sounds like my own. After loosing my home I had to move away from my specialist’s and haven’t been able to get help since. Sadly many Drs advertise they treat FM, CFS but in truth they don’t have a clue. I was put back on antivirals which I was taken off of because it’s toxic effects on my liver. Be careful who U go to for help unfortunately many MD cause more damage than help.

It's quite common for doctors to give a diagnosis of dementia in error, when it should have been hypothyroidism, because the symptoms can be very similar.

Dr Hyman: Shortly after my reading comprehension change - after reading a science fiction paper back (getting, at least though the first of it), A Major changes in my mental function took place. I believe this caused me to be diagnosed with a learning Disability, and to repeat first grade. I had the typical high sugar diet - along, with a very healthy diet, prepared by my mother.

👍🏆Truly an excellentlly fascinating video from beginning to end. Loved hearing it, as well the wealth of valued and useful information presented. [From] The telling of your own story and how it segued into all that you discuss was just filled with hopeful "oh my's" and "what if's" for me or for a loved one and others everywhere that can be helped. It was fresh perspective on causations (for my understanding as a cumulative involved to sort out and resolve to get a base foundation to move through one by one as indicated next, next, and next so on and so-forth ) to maybe finding a way back to health better heath... not through just newer and pricer or long term used Rx's with its own set of issues it too may present.. Which are all likened to me as the old early 1900 version of swapping out a blow-fuse in an electrical breaker with a penny. ..And yet the wiring to the breaker has blown the fuse, because it can't handle the load put on the circuit. The penny is only an emergency resort and not wise to begin with. As well the medication will not resolve the problem issues, merely help postpone some portion of the issue until it can't ether handle the load or send the problem to next weakened area. Loved the thoughts and the interactive dialog. Was truly inspiring information. 🏆👍

Hi six quite a few of my problems from them poisoning me in the hospital. My eyesight happen overnight I used to have 1520 vision. I woke up one morning and could not see just everything was a big blur. I’m still not sure what caused it but I’m slowly getting my eyesight back from listening to Andrew Huberman I’ve been isolated since 2018 in my apartment except for the occasional doctors visit I’ve been looking at stuff up close too long and not getting any sun so I’ve been watching the sunrise listening to classical music, relaxing and little by little my eyesight is returning I only wish I had family or a friend to help me This is been a long hard struggle because when I got sick even my adult children just took their self out of my life I almost feel like they’re waiting for me to die so they don’t have to pay me back the 10,000s of dollars they Omie it’s so unbelievable I broke my own cardinal rule never let anyone use your credit cards not even for Covid or for GROCERIES cause they’ll rack it up so high And basically that’s what happened to me but I’m paying the bills out of my Social Security disability. I know I don’t have to pay him the credit cards sorry I have to use Siri and a micro whatever glass to be able to even do this. I keep praying God will send me somebody to help me, I’ve actually reversed a lot of stuff but I have to order groceries from Walmart on my iPhone and I can’t hardly see to do that then their food is crap and I can’t cook for myself. No I’m not trying to see a sad song and I know some words are going to be messed up, so don’t Lie I don’t really care if you say something bad about my punctuation or spelling because there’s nothing I can do about that and I really don’t care what you think. I send videos like this to my family and they won’t listen to me. Almost everyone in my siblings have kidney cancer, bladder cancer, but I sent him your documentary and this video. I don’t know what’s wrong with them. They’re on cholesterol lowering medicine statins I don’t know what all they’re on my doctor prescribe them to me because my A1c was off the chart but I knew the hospital poison me with insulin. I didn’t have type two diabetes And a sinus infection when I went in then they use me for a guinea pig giving me steroids it all so much death I mean I was hallucinating in the hospital and I kept telling my daughter what they were doing to me, but she didn’t believe me, but I’m still alive I’m exercising it’s not easy. I use my walker to exercise with. I’m starting to be able to get off the oxygen. I don’t even know who I am COMENTY I need someone to talk to you I guess I hope you take this man serious because he knows what he’s talking about, I studied some of the great pioneers of functional medicine. They didn’t call it that then they called it alternative medicine but to me the medical field is alternative, eating healthy and supplements and Winnie minute sorry when he mentioned Linus Pauling, how are used to take Linus Pauling, vitamins, and Terry pass away, but I remember when he got the Nobel prize for discovering I believe vitamin C complex her I don’t know how time to do her vitamin C and Adele Davis who talked about Leah trail and apricot pits to get rid of cancer but the government hash that up real quick like anyway I am so tired of this I just hope people will listen to this man he’s trying to help you and especially if you got some family member that I’ll help you. You’re blessed beyond belief. My daughter lives 10 minutes from here and I probably shouldn’t even talk about that because I’m afraid I’m dying of a broken heart and you know you can die from that.

My request to Dr Hyman: List for us what is specifically on your day to day menu, the food, beverages, supplements, the quantities, and roughly when you consume them. There are 1000's of health experts giving us advice on youtube, NONE of them are willing to tell us specifically what they consume. Obviously we are all a bit different, but a view (a healthy nutrition expert) of your regime, would speak volumes, and give other healthy people like myself a view of what a medical professional does to keep healthy.

[@carmenross1077]

Can you imagine those problems happening right now to layman who doesn’t know anything what to ask, and from the information stories of your case , those people just go nowhere,get worse or even chronically sick and die.
