Coffee Can Reduce the Risk of Alzheimer's 242

Amenacier writes "Recent studies by Finnish and Swedish researchers have shown that drinking moderate amounts of coffee can reduce the risk of Alzheimer's disease in people. The reason for this is as yet unknown, although it has been hypothesized that the high levels of antioxidants found in coffee may play a role in preventing dementia and Alzheimer's. Alternatively, some studies have shown that coffee can protect nerves, which may help prevent Alzheimer's. Other studies have shown that coffee may also help to protect against diabetes, another disease which has been shown to have links to Alzheimer's disease. However, researchers warn against drinking too much coffee, as 3 cups or more may cause hallucinations."

    An old couple both have Alzheimers. They're watching TV and an advert for a burger joint comes on.

    "Hey," the man says, "burgers would be great! Could you make some? I'd like lettuce, tomatoes and onions on mine. Don't forget! Lettuce. Tomatoes. Onions."

    Wife replies "Lettuce, tomatoes and onions. Got it. Lettuce, tomatoes and onions."

    About 2 hours later she comes out of the kitchen and hands him a plate of bacon and eggs. "You idiot," he cries, "you forgot the toast!"

      Forget the hallucination stuff. Look at the spider web studies.

      Various studies have been done giving drugs to spiders, and using their webs as evidence of the effects. My family doctor has a poster of these webs in his offices to show patients what these substances can do to you, and I think most people would be shocked at how extremely the spiders were affected by caffeine, which you can see in this photo [].

      My wife's mother has Alzheimer's, and she lives with us, so I'm acutely aware of what it does to people, and heavy doses of caffeine is definitely the lesser of two evils here. But it will still be nice to have a treatment that doesn't have it's own harsh side effects.

      • by TheLink ( 130905 )
        Dose is important. What caffeine dosage were the spiders on?

        Also, caffeine is used by plants as a pesticide vs insects so it may affect spiders more than humans even on a per body weight dose. Though spiders aren't insects I won't be surprised if they are closer to insects than humans are when it comes to caffeine.

        I'd agree with that. I had a couple of cups the other day, and my web turned out completely crap - didn't catch any flies either. You know, not all of us have been bitten by a radioactive spider or are in any other way closely related to spiders. You'd be better off warning people off chocolate by showing pictures of dead dogs - at least they're mammals.

          The worst part is that we've had several generations of misinformation about the "evils of drink" because of religious zealots who accepted the backing of the Women's Christian Temperance Union [].

          We still see their effect today with churches that use grape juice instead of wine for communion:

          Although many times the WCTU was very involved in religion in a positive manner, they did not agree that wine should be used in their ceremonies. They asked the Church to stop using wine in their ceremonies during an Episcopal convention, and to use un-fermented grape juice instead. Their direct resolution stated that they wanted the church to use grape juice because wine contained "the narcotic poison, alcohol, which cannot truly represent the blood of Christ."

        The benefits of alcohol depend on which specialist you talk to. A cardiologist might recommend it because the alcohol tends to reduce plaque build up in the arteries. A gastroenterologist will tell you to avoid it because metabolizing alcohol leads to fatty build-up in the liver. The neurologists tell you that it kills your nerve cells.

        What this all means depends on your body chemistry. If you come from a family with a history of heart trouble, the alcohol might help keep that under control. Sure you'll get some fat build up in the liver, but your body can cope with that. Someone with a history of degenerative neurological disorders might want to shy away from it.

        Most things in medicine are trade-offs and affect people differently.

        • We now know that the "alcohol kills nerve cells" is wrong in low doses. The "100,000 brain cells per drink" is a myth. As for the fatty buildup in the liver, that's also related only to *over-consumption*, so there's no downside to moderate consumption, and a definite set of benefits.

      Actually, that's not true, unless you can point out the negatives of drinking 175ml of red wine per day. Good luck, because they do that and more in countries with some of the highest life expectancies in Europe. The thing about food is that what is good for you is usually good for you in small amounts, but that what is bad for you is NOT usually bad for you in small amounts. All things in moderation, and there are very few of these 'negatives'. That's what they mean by a balanced diet.

    I can vouch for the dangers of too much caffeine.

    I accidentally started drinking a lot more caffeine than usual, and after a while, I started having worse and worse tremors. My hands would shake. The day I went to see my doctor about it, I had to concentrate furiously to get my hand steady enough to sign my signature at the front desk.

    We didn't know what was going on. I was certain it wasn't the coffee I was drinking, because coffee had never been a problem for me before. My doctor gave me some tests, and told me he was sure it wasn't anything scary (Parkinson's disease or something). He recommended I start taking magnesium supplements.

    I took the magnesium and it helped right away! Then over time the tremors started to get worse again. I was starting to get scared.

    My doctor sent me to a neurologist. I decided to cut out all coffee for a week or so before visiting the neurologist; I was still certain coffee wasn't the cause of my problems, but I figured it would be helpful to remove one variable from the equation. After being tested in various ways while hooked up to cool machines, I was ruled not to have anything scary. More importantly, after a week with no coffee, I was starting to feel a lot better.

    So I decided to stay off the coffee. I had some bad withdrawal symptoms (headache, etc.) and took a lot of aspirin and ibuprofen. (And around this time I started to get bad tinnitus [] on top of everything else!)

    Now I am mostly off caffeine. I sometimes have a single cup of caffeinated coffee. The tremors have passed and I'm grateful that my symptoms are gone. (The tinnitus stopped when I stopped taking the aspirin and ibuprofen.)

    An important thing I want to tell you: I never drank a cup of coffee and then immediately had my hands start shaking. I had a gradual onset of hand tremors and it was chronic, with no obvious increase right after I drank coffee. This convinced me the tremors could not be caused by the coffee, but now I am convinced that they were.

    You may be wondering how I could accidentally start overdosing on caffeine. Well, I started working in a building where the coffee was awful (Farmer Brothers commercial coffee service), so I started making my own coffee using an Aeropress []. This is an excellent coffee maker (Dan likes it! []), and I still use it and recommend it. But when I first got it, I was using caffeinated coffee, and I was trying to make "doppio ristretto" portions for myself, so I was using two scoops of finely ground espresso beans. I now believe that one AeroPress scoop of coffee makes a double shot, so I was effectively drinking four espresso shots worth of caffeine; and I usually drank two of these per day. So while I thought I was drinking 4 espresso shots worth of caffeine, I suspect I was drinking 8 shots worth, possibly even a little more.

    As the saying goes, the dose makes the poison. I drank reasonable portions of caffeine for years and didn't notice any ill effects at all; it was only when I drank too much that I had the scary tremors.

    If you get hand tremors, I do suggest you cut out all caffeine for a while and see if it helps.
