Walking may put the brakes on cognitive decline in healthy older people as well as those with cognitive impairment, a new study finds. The ongoing study, which spans 20 years, also quantified how much walking is necessary to keep brain volume up. Researchers followed 426 older adults for a number of years to see if there were changes in brain volume. Among the participants 299 were healthy, and 127 had cognitive impairments, including 83 with mild cognitive impairment, and 44 with Alzheimer's disease.

Asserting "we are at an exceptional moment" in the hunt for an Alzheimer'sdiseasetreatment, National Institutes of Health director Dr. Francis Collins on Tuesday promised a raft of new research aimed at stopping and reversing the memory-robbing disorder by the year 2025. In unveiling a first-ever "national strategy" on Alzheimer's disease, Collins launched several new projects and clinical trials--including a whole-genome sequencing effort to identify genes that confer vulnerability to--or protection against-- Alzheimer's, and a trial to explore whether an inhaled form of insulin will slow progression of the disease.

In the world of “promising” multiple sclerosis drugs, it’s been quite a week. Two more experimental drugs -- both in pill form, not injected -- are joining the race of new treatments to slow the disease. A study of multiple sclerosis patients who took the drug laquinimod over two years had 23% fewer relapses -- an attack of new symptoms or worsening of old ones -- compared with patients who took a sugar pill. The group that received the drug also had a 36% reduction in disability progression and a 33% reduction in brain atrophy.

Alzheimer's disease threatens more and more people in the United States as the population ages. Anyone concerned about himself or herself or a loved one can get a free memory screen Tuesday at one of more than 2,300 locations across the nation (Tuesday is the Alzheimer's Foundation of America's National Memory Screening Day). The five-minute screenings -- which are to be available at doctors' offices, hospitals, senior centers and K-Mart pharmacies, among other locations -- are confidential.

If you have diabetes, it may help to buddy up, a new study suggests. Peer support may help control the disease that accounts for an increasing number of hospitalizations. The study published Tuesday in the Annals of Internal Medicine paired up diabetic patients who had high blood sugar levels despite being on a treatment path. The six-month study found that participants benefited from meeting with a peer or peers in a group setting who reminded them to take medications, follow a diet and continue other lifestyle changes that are critical to controlling diabetes.

Not that most people are eating even five servings of fruit and vegetables every day - but that might not be enough to get the best protection from disease and early death, said researchers who also found that vegetables do more good than fruit. Might the new call be at least seven a day? And if the fruit came from a can or the freezer, it might be doing more harm than good, the researchers reported in the Journal of Epidemiology and Community Health . “We found a strong inverse relationship between fruit and vegetable consumption and all-cause mortality,” they wrote.

In the third gene-therapy success of recent weeks, French researchers have arrested the progression of the rare and fatal degenerative disorder adrenoleukodystrophy, which was at the heart of the popular movie "Lorenzo's Oil." The disease has stabilized in two boys who were 7 years old when the therapy was performed two years ago, the team reported today in the journal Science. "This is a disease that never, ever stabilizes" on its own, said Dr. Katherine High of the Children's Hospital of Philadelphia, who was not involved in the research.

I applaud Money's letter, saying alcoholism is the ultimate effect of a series of purposive decisions, not a disease. To say alcoholism is a disease is like saying overeating is a disease that the individual is powerless to control. What happened to the idea that people ought to control their impulses? It's time we return to self-discipline. FRANK P. BURTON Santa Monica

Germs and detectives might not seem like they're connected. But their link, as a certain fictitious sleuth might say, is elementary. In Thomas Goetz's fascinating and entertaining new page turner of a book, "The Remedy: Robert Koch, Arthur Conan Doyle, and the Quest to Cure Tuberculosis," we are transported to the final decades of the 19th century. The age of electricity was dawning. And in laboratories and on imaginary London streets, men armed with microscopes and the power of observation first used science to tackle the twin scourges of crime and disease.
