On the brain: Mental notes for Mom

With Mother's Day coming up on Sunday, here are a few tidbits about the brain that you and your mom can both appreciate:

If your mom is middle-aged, she should know about new research connecting weight and dementia, the most common form of which is Alzheimer's. The Los Angeles Times reports on a study in the journal Neurology showing that being overweight in midlife increases dementia risk by 70% or more. It's not clear why researchers found this association, but inflammation from excess weight may lead to brain cell damage and dementia. Diabetes and vascular disease, which could contribute to dementia, are also linked to higher body mass index (BMI).

Dr. Drew: Tough, grown-up choices for teen moms

May 4: Not a holiday. Not a special occasion. But it is one of the most important days of the year - The National Day to Prevent Teen Pregnancy. Too many of our children are having children.

The U.S. has double the teen pregnancy rate of Canada. It’s four times greater than in Germany and France. And eight times higher than in Japan. America’s rate of teen pregnancy is the highest in the developed world. I’d love to focus on the fact that fewer teens are having babies now, than 20 years ago. But I can’t. Not today, anyway.

I work with MTV’s “Teen Moms." I come face-to-face with young girls who are pregnant - 16-year-old girls who may have to failed to use protection or have used it correctly. They are shocked to find themselves in “trouble."

Gupta: How did Giffords survive?

Don’t miss “Dr. Sanjay Gupta Reports: Saving Gabby Giffords,” on Sunday, May 8 at 7 p.m. ET. The documentary reveals exclusive details of the extraordinary efforts by paramedics and doctors credited with saving the life of the congresswoman. You can also join Dr. Gupta for a LIVE chat on Twitter during the program.

While traveling around the country the last few months working on an upcoming documentary about Congresswoman Gabby Giffords, people would often stop me and ask questions. “How exactly did she survive?” was a common one. “Will she return to Congress?” was another. One woman stopped me at an airport by gently grabbing my forearm. “Gabby –  isn’t it a miracle," she stated, more than asked

As a neurosurgeon, I have taken care of many patients with gunshot wounds to the head. If you look at national statistics, only around 5 to 10% survive

From the moment Giffords was shot, the odds were stacked against her. So, how did she survive?  I want to take you through the critical analysis that takes place in the trauma team’s minds.

Study: Immigrant Hispanics less stressed, healthier

A new study finds that foreign-born Hispanics living in the U.S. experience significantly less stress than American-born Hispanics.

The study, published last month in Du Bois Review: Social Science Research on Race,  concludes that in addition to education and income disparities, higher levels of chronic stress among Hispanics and African-Americans leads to worse health outcomes in those populations.

But foreign-born Hispanics showed lower levels of stress, similar to whites, while American-born Hispanics showed higher levels of stress, similar to African-Americans, the study showed.

Sex in the age of bin Laden

Ian Kerner, a sexuality counselor and New York Times best-selling author, blogs about sex on Thursdays on The Chart. Read more from him at his website, GoodInBed.

I started a family in the Age of Terror. My wife Lisa and I were married on December 1, 2001, and we chose a simple trip to the Caribbean for our honeymoon over the dream of Bali.

Some of our friends thought we were crazy to let the fear of terrorism affect our plans, but when a nightclub in Bali’s tourist district was bombed months later, we felt justified in having allowed our world to become that much smaller.
