In this week's health alert, we learn about men's life expectancy and June is Alzheimer's Awareness Month.

A new survey finds that 4 out of 5 men have never talked with a family member about sexual health or their family's health history.

Life expectancy for men is at least 5 years less than for women and of the top 10 causes of death in the U.S. men are more likely to die from 9 of them than women. Women are more proactive. Men need to follow their lead, get the health conversations going and practice early detection.

June is also Alzheimer's Awareness month.

MedStar Georgetown is recruiting patients and families, especially minorities, for several Alzheimer studies. One needs participants to help determine the impact the drug NILOTINIB has on mild to moderate cases of Alzheimer's. And the first major prevention study, the Generations Study is open for those with an inherited genetic risk for Alzheimer's who have not developed memory issues.

Dr. R. Scott Turner, director of the Memory Disorders Program at Georgetown, says minority participation in these trials is crucial to finding answers.

"We need volunteers from everyone, Af-AM, Hispanics, Caucasians, everyone so we know the difference in the disease in different populations and if our drugs are going to be effective for all populations and not just one population," said Dr. Turner.
