If you notice these early signs of dementia, you need to act now.

Today I’m going to cover six early signs of dementia. Keep in mind that these could also be signs of other things like a lack of sleep, a blood sugar problem, or many other things—not necessarily dementia.

Dementia is a mental decline. Certain parts of the brain are actually shrinking—specifically the hippocampus.

6 early signs of dementia:
1. Difficulty organizing and planning things
2. Personality changes
3. Constipation
4. Sensory dysfunction
5. Language problems
6. Problems navigating

If you think you’re showing early signs of dementia, it’s best to act now. Don’t wait until it becomes a bigger problem.

Important things you can do right now:
1. Take vitamin B1 (nutritional yeast)
2. Fix the gut (consume a variety of vegetables, get on a low-carb diet, consume organic foods, and do fasting)
3. Consume sprouts (broccoli sprouts)
4. Generate ketones (do intermittent fasting and prolonged fasting and take MCT oil or exogenous ketones)
5. Consume ginkgo biloba
6. Consume lion’s mane mushroom
7. Consume omega-3 fatty acids, vitamin D, and zinc, and get plenty of exercise and sleep

      Both on my parents suffered from dementia. Both started showing signs at about 80, and both lived to be 89, but by the end neither one knew my name anymore. My dad actually got more easy going, but my mom became paranoid, combative and argumentative, and lost her great sense of humor. My brothers and I took care of her at home for years before a stroke put her in the hospital and then a nursing home the last 1 1/2 months of her life. Every day was a battle with her. She didn’t want to do anything she needed to do, told each of us we didn’t love her, accused us of trying to poison her when we gave her meds, told us we’d be glad when she was dead, and so on. It was really heartbreaking, and hard to deal with emotionally.

        Ironically, the side effects of the meds means in effect, your Mother was not wrong !! But as they were doubtless prescribed, there was probably very little, if anything, you could have done about it.
        And let’s be honest, however great the tragedy of the entire thing, are you really telling me you were not relieved when it was over ?!!

      • Lloyd Hlavac

        @Maius26 Well one of the meds was for hypothyroidism, which if you don’t take it, the problems are worse than any side effects of the drug. Another was a blood thinner, because of a danger of blood clots, which obviously is more dangerous than any of the med side effects. So yes they were prescribed and necessary.

        As for relief when it was all over? Yes, absolutely. My mom never would have wanted to live the way she ended up living, with such mental decline and such anguish & turmoil in her soul. And yes, there was great mental/emotional stress on both me and my brothers who all took care of her at home for years. Yet I still sobbed like a baby when she died.

    • Lisa Banaszak

      As a nurse who has worked with many dementia patients over the years I have an analogy of what I think they go through in the later stages. A person with dementia or Alzheimer’s is in a dream. A dream they cannot wake from. Think about your dreams of being somewhere & you’re lost-can’t call home-can’t find your car/house ..you are just wandering around lost. That’s dementia.

      • siouxzqz1

        My father had dementia. But his cycled. For three years he would go from almost normal for a day or two, then he would become much more verbal, aggressive and often mean, then belligerent argumentative and once in a while violent, then as the mania increased he would hallucinate and yell at night and not sleep for days. Then almost as if his brain burnt to a crisp he would become a zombie, sleep for 24-36 hours and when he woke up he was okay again. The sleep healed whatever had built up in his brain and fried it. But then gradually it would build up again. This happened like clockwork. Something was building up which then only was healed by an extended period of sleep. I know every patient has their own personal form of dementia. Some are quiet and gentle some are violent and psychotic. And some can be both, leaving the caretaker to wonder who is going to appear. It is a hellishly cruel disease for the afflicted and for the caregiver.

        Not evidence based practice then. Nice one.

      • Stew Bugz

        That made me so sad. My grandma died from dementia. My grandfather cared for her and was in his 90’s doing so. He said she would remember every so often him and her life. The day she died she told him she loved him and had a wonderful life with him. She had not talked a full sentence I. Four years.
        Gif bless you for caring for our loved one’s suffering from this awful disease.

        those memories, only you and her shared…

        I lost my grandmother decades ago to this and it still breaks my heart that I was young and should have done more to spend time and care for her. I miss her every day. You’re mother is so very lucky to have gotten to be loved by you so well.

    • soarornor

      One thing I’d add to the list of causative factors is too much constant prescription medication. Most elders are on at least 12 medications working in combination. When I checked my mom’s meds out, everyone of them had memory loss as a potential side effect. When a person is going down that path the symptoms can seem like dementia and unfortunately they’re too out of it to be able to properly complain with an accurate description of what they’re feeling. So they’re written off as an age related dementia/Alzheimer’s patient. If a loved one is having cognitive issues the first thing I’d check is what prescription drugs are being taken and to gradually get them off every one unless absolutely needed. Most doctors are amazingly passive about this issue. Since their income streams are tied to this they’re only too happy to prescribe more. This over prescribing of drugs is the worst health destroyer there is. But it’s a goldmine for doctors.

      • J Watson

        Not really a problem when you have universal healthcare, there’s no incentive for doctors to push pills on you which you don’t need.

      • HelenHighwater

        Primarily a goldmine for Big Pharma with whom to many MD’s are in cahoots.

      • Keith Marking

        No, I’m not a physician, pharmacist or chemist, but as someone of above average intelligence, and through years of observation, I can conclude that the way medicine/pharmacology is practiced today is barbaric. There is no regard for chemical interactions, and common sense dictates there would need to be clinical trials and FDA approvals for an endless combination of pharmaceutical poisons. Obviously, this doesn’t happen. Physicians are dangerous because they believe themselves to be intellectually superior, which results in a willingness to “do what’s best” in their opinion (I lived with Med students for a year, trust me on this). Pharmaceutical companies SHOULD NOT be permitted to advertise directly to consumers (we’re one of only TWO countries in the entire World that allows it). The protocol should involve the elimination of direct-to-consumer advertising, and newly prescribed medications should be part of a consultation between the pharmacist who fills the prescriptions and the treating physicians. Of course, the egos of physicians and $$ influence of big pharma will ensure this never happens. Heal thyself!

      • 91Parabellum

        Thats just not true. I work as a doctor in a special ambulance for early dementia diagnosis. In all patients i remember i have seen 1-2 cases where i suspected the medication as the cause for cognitive impairment, the rest was explained by other issues.

    • Shelly Milligan

      Thank you so much for this! I am a 2x cancer survivor. Leukemia at 14 and CNS relapse at 20. Both times they did chemo including (sp ?) intrethecal chemo but with the relapse they also did high dose radiation to my CNS. Now38 years later I have early onset dementia that started 12 years ago. I have had a stroke, lost the vision in most of my right eye, have no depth perception etc. anyway Thank you❤️

    • Tony Kennedy

      In the last few years of his life, my father suffered numerous seizures and after each one it seemed his mind became weaker and weaker. He ended up with terminal cancer and that really expedited the degeneration of his mind. He had all the classic symptoms of mild-moderate dementia such as memory problems, mood changed etc. But the weirdest symptom was he would tell remarkably complex stories that were complete lies. These stories would be quite advanced (to the point were the level of English used would have been superior to his pre-dementia state). I remember he told me that the “doctors thought his problems were being caused by an accidental chemical spill at a local plant, that was being investigated by the authorities”. It was so convincing I actually googled it (it never happened). And the next day he didn’t remember anything about it.

      Is that a normal symptom of dementia or was that something else?

      • Lucy W.

        When i was a carer i used to go to a lovely elderly man, he had suffered several small strokes, and had more symptoms of dementia appearing after each one..he used to tell us carers some wonderful stories, as you said, very detailed, very entertainting to listen to…only after a couple of weeks of visits did we meet his daughter who told us they were complete nonsene, and he’d only started doing it since the onset of the strokes..he was great fun to care for..in 10 years of that job i think i only saw one other person, a lovely lady who has us all convinced she’d won wimbeldon as a girl in the 40’s..so, though it was defintiely part of their dementia symptoms, i dont think its a very common one.

      • allykatharvey

        I don’t think this is a classic dementia symptom but more like another brain problem brought about perhaps by a stroke.

      • Lucy W.

        @allykatharvey its very much a typical symptom of dementia. there are all different types of dementia, and many, including vascular dementia can be brought on by a strokes..even ones so small theyve gone unnoticed

    • Hiromi 1209

      Dear Dr. Berg, Thank you so much for your great videos. I’ve been on the ketogenic diet for 5 years now, but I’ve only recently discovered your videos. I am a 59-year-old Japanese living in Europe and have had three surgeries for cervical cancer and polyps in the nose and the uterus. I had lost my father due to cardiac problems and stomach cancer, and my mother lives with Altzheimer’s disease. They were very careful about what to eat and skinny. In retrospect, I believe they had the glucose-insulin problem. I wish I had known your videos much earlier! We can watch your video with subtitles in many different languages, but not in Japanese. I’m an experienced translator, so would you allow me to produce Japanese subtitles as a volunteer translator? I truly appreciate your policy to educate people about the root causes of diseases, and I want the Japanese people watch your videos. There are many people in Japan who need the knowledge that you share with us.

    • t75kab11

      Thank you for discussing dementia. My mom was diagnosed with dementia and then Alzheimer’s. What a nightmare. I believe it is harder on the family, caregiver when it reaches a certan point. They don’t know what is going on and it is very difficult to watch someone you love suffer with this. We had to put alarms on all the doors because she would try to out. She was convinced my father (who had passed away 18 years ago), was living under her bed and would put plates of food for him under the bed. She couldn’t understand why he wasn’t eating. Very sad.

        God bless your parents. I lost my mom a year and a half ago. This must have been traumatic to you. My grandmother went through the same thing. It is hard to watch.

      This is incredible. I am a physical therapist assistant so clearly I don’t diagnose anyone with dementia but I do home health care so I work with these patients. It’s amazing how what you eat as well as your urogenital health affects your mind. When I see a patient who is normally pretty sharp but suddenly seems confused… Nine times out of 10 it’s a urinary tract infection.

      • C.B. Barlow

        I’m right up there with you. My Grandfather once told me that he didn’t think I’d have to worry about it, but as both my grandma and her eldest daughter had it, I’m not taking chances.

    • HappyFunFunGirl

      Thanks Dr. Berg for your fantastic videos. So helpful!! I’m a zebra, survivor of a rare endocrine tumor- pheochromacytoma. It caused extremely high levels of cortisol. At the peak, before diagnosis, I had all of these symptoms. It was akin to having Alzheimer’s. I started getting lost on my daily commutes to/from work which was 90% freeway.
      My memory became horrible.
      After removal things normalized a lot. I was 32 and very athletic.
      I’m lucky to be alive. Barely survived heart failure and all sorts issues. I’m often curious what the long term affects of living in that state might be. Not much info. I empathize with anyone experiencing that level of confusion. Its hard to be aware enough to know something isn’t right, and sensing frustration from everyone around you, but not aware enough to comprehend the full extent of the issues. Asking for the time every 5 minutes was annoying to everyone, but to me, each time was like the first ask. Hormones are key to health, on every level. More info on how to reset those would be great.
      Thanks again for being awesome!

      Dr. Berg, my mom and grandmom had dementia. Although their doctors could not do a direct blood test to test for it they went by their symptoms, which you mention here exactly. Though they also had other conditions as irritable bowel syndrome, reflux, depression, stress which sometimes would not let them sleep which I think worsened their dementia, etc. One physical effect from dementia that further alerted their doctors was that the brains of my poor mom and grandmom were being reported on their CT scans as ” shrinking ” and ” losing volume “. It was heart breaking to hear such things and it was hard for them too because they realized that they were having problems with their memory and were not able to do much about it. Their doctors did not make any recommendations about it either. You do. This parallels what you talk about in this video. Dr. Berg, you are a Godsend for helping us understand such things. Your presentations are going to help a lot of people at least improve their health because they are very clear and excellent. I lost grandmom at close to age 103 at a nursing home which did not care much about her by putting her in a room with no heat. She had dementia, but she could still talk and reason. Her hearing and sight made it tough for people to see how far her dementia was, but still a life is a life. Just because someone has dementia they are still a human being. They would not feed her or clean her. I had to do it. They did not even give her the medicines. Eventually she got chest congested and got pneumonia from the cold room. Their own radiologist told them to do follow up care after finding pneumonia on a chest X ray. They ignored him. They did not even tell me about it and just let her drown in her own lung secretions. The least they could have done was call 911 to send her to a hospital. They even refused to give her back to me. I also found her with bruises on her forehead which they ignored to explain. New York State, the Department of Health and even the District Attorney all protect these nursing homes. They all ignored us. This was a nursing home in the Bronx, Riverdale, New York. Diseases like dementia puts us all in danger if we are alone, find ourselves in a situation like my grandmother with criminals who took away her life and fear no prosecution, and if we live in a state like New York that does not prosecute repeat offenders from nursing homes and does not care about the elderly population. Age should not be a death sentence to our parents or grandparents, but that seems to be the pretext that they use to hurt them, including dementia. Thanks

      I had ALL of these symptoms during a time of severe stress in my life and they all resolved when better times came along. Diagnosing dementia in early stage is difficult.

        I had all those symptoms when I had anxiety and depression too 👍🏻

    • April Blossom

      Sometimes I reassure myself and others that I may have had dementia at 6! My Mother had sent me to the shops with a ten Shillong note but it seemed to disappear and then re-surfaced months later under the doll’s pram mattress… also there is a lot to be said for lifestyle when it comes to ‘short term memory loss’ as there can be too much sameness and lack of stimulation when stuck at home in retirement so it is good to remedy this and try to stay alert and interested in life. Brilliant informative article thank you.

    • Justin Burch

      My mother-in-law had signs of dementia and we took her in for a full physical and it turned out she was actually severely anemic. The doctor put her on some high iron medication. It took three months but her iron went slowly up. After we got that fixed all her dementia symptoms were gone. I really appreciate your cautionary thing about not diagnosing your spouse.

    • Sara Kimmel

      Yes, my mom is dealing with dementia and a UTI made it worse. Years ago I went over her meds, took her off cholesterol meds (statins cause memory loss), and others she did not need. She got better. Sounded normal. She is now in a home, Kaiser prescribed amlodipine and I said NO! It causes memory loss and she is in MEMORY CARE AT THE HOME! I researched and found out that Fiji water that is high in silica flushes out aluminum through our urine. Also Taurine is good for memory loss, and vitamin B12. I put it in her nightstand and would give it all to her when I visited. I noticed yesterday that it was gone and questioned the main people at the home. They said they took it b/c they cannot allow any medications that are not on the Dr’s list. I said TAURINE, CRANBERRY CHEWS AND B12 ARE NOT MEDICATIONS THAT’S WHY I WANT HER ON THEM. They said they need her Dr. to approve them. I said HER DR. APPROVED A BLOOD PRESSURE MEDICATION (AMLODIPINE) THAT CAUSES MEMORY LOSS!!!! You guys, you need to do your own research and demand things. They CAN get better!

      • Kelley Wyskiel

        Good on you! Stay on them and take care of your mom.
        I worked as private care for years and you’re absolutely right on everything you’re doing.

    • Jesse Halter

      I have a question. I’ve had prolonged trauma growing up, and my memory is pretty shot. Also, it’s really hard for me to form thoughts into verbal words. It’s just really slow, and comes out way more simplified. Within the past five years or so I learned that it doesn’t really apply in texted form. I can express myself much more easily. I’ve been wondering if it’s hooked to the many problems I developed from the trauma I’ve experienced, or would that be a physical brain anomaly? I don’t have pre-trauma memory, as it started a very young age. So I don’t have a time to compare how my brain operated then vs now.
