Many middle-aged and older adults with diabetes are sexually active according to a study of nearly 2,000 people aged 57 to 85 presented in the September 2010 issue of the journal Diabetes Care.

In Alzheimer’s disease, the problem is beta-amyloid, a protein that accumulates in the brain and causes nerve cells to weaken and die. Drugs designed to eliminate plaques made of beta-amyloid have a fatal problem: they need to enter the brain and remove the plaques without attacking healthy brain cells. New research from the laboratory of Nobel Prize winner Paul Greengard, however, suggests that treatments modeled on the blockbuster cancer drug Gleevec could be the solution. The findings are reported in the Sept. 2 issue of the journal Nature.
