...procedure involves injecting radioactive material into the brain of the suspected Alzheimer's victim and then taking photo-like images which record the pattern of blood flow in the patient's brain...
Alzheimer's victims have a decreased blood supply to certain brain areas, said Dr. B. Leonard Holman, the hospital's director of nuclear medicine. Holman and a team of doctors found that many of the disease's victims have identical brain "signatures," or blood flow patterns...
...alternative approach to unclogging the arteries is based on what scientists have learned about cholesterol. Plaques are more likely to form when blood cholesterol is high, and particularly when the cholesterol takes the form known as "low-density lipoprotein" (LDL). By lowering the levels of cholesterol in the blood or by ensuring that most of it occurs as "high density lipoprotein" (HDL), the risk of heart attack can be substantially reduced. Although, several drugs have been developed to improve blood cholesterol levels, most have been associated with severe side effects...
Alderman and his colleagues gave patients up to two grams of niacin--more than a hundred times the recommended daily allowance of the vitamin--and found that blood cholesterol improved in 90 percent of the cases. The drug was particularly effective at raising levels of HDL (the type of cholesterol that is protective against heart disease), but it also lowered total cholesterol levels in patients taking higher doses of the drug. In general, the researchers reported, the more niacin a subject took, the greater was his improvement...
...study of heart patients, they found that taking eight teaspoons of cod liver oil every day for six weeks produced several changes associated with cardiovascular health. The treatment raised blood concentrations of HDL cholesterol, lowerered the rate of blood clotting, and increased production of chemicals which cause dilation of blood vessels, making arteries such as those that supply the heart less likely to get blocked...
