Computers detect Alzheimer's disease in brain scans

Computers can be trained to detect early signs of Alzheimer’s disease in MRI brain scans, according to a new report. The finding could help doctors diagnose the disease earlier and more accurately than they can now, so treatment can begin earlier. more  

Detecting Alzheimer’s disease: Research aims for earlier diagnosis

Do you ever forget where you put your car keys or what you were supposed to pick up at the grocery store? You might worry that these memory lapses, or “senior moments,” could be an early sign of Alzheimer’s disease (AD), an irreversible brain illness.

Smoking alters gene activity in lungs and tumors

The strong link between smoking and lung cancer has long been clear, but the underlying genetic and molecular changes have been harder to pin down. Now NIH scientists have shown that cigarette smoking distinctively alters gene activity and that these changes can persist for years, contributing to cancer long after a person has kicked the habit. more

Cigarette smoking and cancer: Questions and answers  

Cigarette smoking causes 87 percent of lung cancer deaths. Lung cancer is the leading cause of cancer death in both men and women. Smoking is also responsible for most cancers of the larynx, oral cavity and pharynx, esophagus, and bladder. more

Fugitive cancer cells can be blocked by stopping blood cells that aid them

Cancer cells get a helping hand from platelets, specialized blood cells involved in clotting. Platelets shelter and feed tumor cells that stray into the bloodstream, making it easier for cancer to spread, or metastasize. Research at Washington University School of Medicine in St. Louis suggests that inactivating platelets could slow down or prevent metastasis. more
