    Losing your memory in old age sometimes may have nothing to do with Alzheimer's and lots to do with blood sugar.

    So suggests new research that found people who don't process blood sugar normally — a silent, pre-diabetic condition — are likely to suffer poor memory
    and even a shrinkage of the brain region crucial for recall.

    The good news: If the small study from New York University is confirmed, simple diet and exercise could help many people protect their brains from the
    fogged memory associated with aging.

    Maybe the threat of memory loss — an oft-cited fear among aging baby boomers — will provide the final push for people to take those steps, says lead
    researcher Dr. Antonio Convit.

    "That's a great motivator to stay off the calories and stay off the couch," he said.

    For every Alzheimer's patient, there are eight older people who suffer enough memory loss to significantly harm their quality of life yet have no
    dementia-causing disease, says Convit, an NYU psychiatry professor who set out to uncover the causes.

    Blood sugar was a natural suspect because scientists have long known that diabetics are at higher-than-normal risk for memory problems, possibly because
    diabetes harms blood vessels that supply the brain, heart and other organs.

    The new study, published Monday in the Proceedings of the National Academy of Sciences, found that people's memory may be harmed long before they
    ever develop full-fledged diabetes — and that it's a problem of fuel, not plumbing.

    Convit studied 30 non-diabetic middle-age and elderly people. He measured how they performed on several memory tests; how quickly they metabolized
    blood sugar after a meal; and, using MRI scans, the size of the hippocampus, the brain region responsible for recent memory.

    The slower those outwardly healthy people metabolized blood sugar, the worse their memory was — and the smaller their hippocampus was, Convit found.

    Unlike most other tissues that have multiple fuel sources, the brain depends on blood sugar for almost all its energy, Convit explained. The longer that
    glucose stays in the bloodstream instead of being metabolized into body tissues, the less fuel the brain has to store memories.

    Convit's research found no specific threshold at which memory automatically worsened. Instead it was a spectrum: The slower glucose metabolism, the worse
    people did.

    Once that metabolism reaches certain levels, it becomes a condition called "impaired glucose tolerance" or pre-diabetes, thought to afflict millions worldwide.
    It strikes mostly in middle age, although people of any age who are overweight and sedentary are at risk — and Americans are getting fatter every year.
    Without treatment, pre-diabetes usually turns into full-fledged diabetes, which in turn brings deadly heart attacks, kidney failure and numerous other
    ailments.

    Why did only the memory-crucial hippocampus seem harmed? Previous animal and human research shows it's the region most likely damaged by any brain
    insult, Convit said. Conversely, it's also a very adjustable region, with the potential for some recovery if people bring their blood sugar under control, he said.


    Convit's study sheds important light on yet another risk of bad blood sugar, said Dr. Fran Kaufman, president of the American Diabetes Association.

    She cautioned that it was a small study that requires confirmation before doctors test glucose solely for memory complaints.

    But if confirmed, the same advice for lowering people's overall diabetes risk — drop a few pounds and do exercise as simple as walking 30 minutes a day —
    apparently would help protect people's brains, too, Kaufman said.

    Syndrome X or insullin resistance. The "Nutritional Guide For Syndrome X" is the best book on health I have ever read. Sugar is poison and causes as many problems as identified toxic substances.

    Dr. Atkins and Suzanne Somers address this in their diet recommendations. I've lost 24 pounds on the Somersize diet, my blood pressure has gone from high/normal to low/normal, and all my lipids have improved. My cholesterol has gone from 191 back to 168.

    I believe eliminating sugar and a lot of other carbs helps lessen our symptoms.

    Love, Mikie
