Those of us who are baby boomers or older can remember playing with mercury when we were young. The thermometer broke, and you pushed the little globules around. Or you fooled around with the stuff in science class. My husband says he used to get mercury to flow over the… read more "Mercury Must Be Bad – If Not in Vaccines, In Teeth"
Sometimes diagnosis is straightforward. If a woman has missed several periods and has a big belly with a fetal heartbeat, it’s pretty easy to diagnose pregnancy. But most of the time diagnosis is much more difficult. Alzheimer’s can’t be diagnosed for sure until the patient dies and you do an… read more "Diagnostic Dilemmas"
A long time ago I read a study about what makes a good doctor. Some things you might think were important, like grades in medical school, were irrelevant. What correlated the best was the number of medical journals a doctor read. I don’t know whether that means good doctors read… read more "Reading Medical Literature with a Critical Eye"
Much nonsense has been written about the “art” of medicine. All too often, it amounts to a rationalization for doctors doing what they want to do instead of following the evidence. Medicine is not an art like painting. Neither is it a science like physics. It’s an applied science. Since… read more "The “Art” of Clinical Decision-Making"
Neurologist Robert A. Burton, MD has written a gem of a book: On Being Certain: Believing You Are Right Even When You’re Not. His thesis is that “Certainty and similar states of ‘knowing what we know’ arise out of involuntary brain mechanisms that, like love or anger, function independently of… read more "On Being Certain"
I wonder how many people have heard that chiropractic neck adjustments can cause strokes. It isn’t exactly common knowledge. One organization is trying to raise public awareness through signs on the side of city buses (Injured by a Chiropractor? Call this number) and through TV commercials. I had never heard… read more "Chiropractic and Stroke"
Why aren’t there more women in science and medicine? Just because we lack certain anatomical dangly bits, does that mean we’re less capable? Apparently Harvard’s president Lawrence H. Summers thought so. In a classic case of foot-in-mouth disease, he suggested that innate differences between men and women might be one… read more "Women in Medicine"
Phrenology was a 19th century pseudoscience that claimed to associate brain areas with specific personality traits. It was based on palpating bumps on the skull and was totally bogus. New brain imaging procedures are giving us real insights into brain function in health and disease. They are still blunt instruments,… read more "SPECT Scans at the Amen Clinic – A New Phrenology?"
For years postmenopausal women were told that estrogen was safe. Now they’re being told that estrogen is dangerous. Women are confused. The media haven’t helped; they’ve only increased the confusion and created some myths. Alternative medicine offers the option of herbal remedies they say are safer than estrogen. Suzanne Somers… read more "Hormone Replacement Therapy"
I recently read a fascinating book, The Brain That Changes Itself by Norman Doidge. He describes case histories and research indicating that the brain is far more malleable than we once thought. We used to think each function was localized to a small area of the brain and if you lost that… read more "Thoughts on Neuroplasticity"
