Bouncing Thoughts and Sharp Brains

May 4, 2010 at 5:21 am 5 comments

As I go about my work day, my Boomer brain can become easily confounded by the many distractions and interruptions I encounter. I frequently find myself thinking, “What was I going to say?” or “What was I just about to do?” Such symptoms of bouncing thoughts are typical of many individuals as they age, and while the experience can be disconcerting and/or annoying, two recent stories overheard on National Public Radio helped to reassure me that I’m not necessarily in the beginning stages of dementia.

Morning Edition’s anchor, Renee Montagne, profiled a new book by Barbara Strauch, The Secret Life of the Grown-up Brain: The Surprising Talents of the Middle-Aged Mind. Ms. Strauch is the health and medical science editor at the New York Times and when she began her research, she hoped to determine what happens to the middle age brain that makes us so forgetful. Her definition of “grown-up” (people roughly between the ages of 40 and 65) closely aligns with the widely accepted notion of Baby Boomers (those individuals currently between the ages of 46-64).

Yes, one common indication of aging is becoming more forgetful; however, memory is comprised of different components and some parts of our memory, for example autobiographical details and habits remain strong throughout middle age. It is episodic memory (remembering things in context such as the name of someone you are talking to) and short-term memory that pose problems. As Ms. Strauch says, “It’s a retrieval issue. Those names are not really lost. They’re just kind of temporarily misplaced.”

While conceding that our brains do decline as we age, Ms. Strauch sites research that suggests that the middle-aged brain actually improves in a number of areas including inductive reasoning, verbal memory, and vocabulary. In addition, as we perform tasks and learn, white matter, which is composed of fat and coats the tails of brain cells, increases and brain signals move faster. In fact, Ms. Strauch says that white matter peaks in middle age and studies have shown across all occupations and ethnicities that as people reach middle age, a sense of well-being also peaks and an older brain can see connections and solve problems better than a younger brain!

Rather than recommending mild mental stimulation to keep your brain healthy, Ms. Strauch says that people may have to work harder than they anticipated. For example, doing crossword puzzles may not be enough anymore because when doing them, you’re retrieving information you already know. She contends that you have to push your brain very hard – make it not comfortable. Some research shows that talking with people who disagree with you is basically good for you since it helps you sharpen your own thinking.

So the next time you become distressed at not remembering a co-worker’s name or where you left you keys, forgive yourself and think about all those areas where we outshine our 20-year-old co-workers: in general we Boomers are better at getting the gist of arguments, better at recognizing categories, better at sizing up situations, better at making financial decisions, and better at social expertise (judging character). And don’t forget to challenge your brain – get out of your comfort zone. The Library has an incredible array of resources to help you do just that!

    Glad you found the article useful! Ms. Strauch’s research was reassuring to Boomers on our staff and while many of us do practice mental exercise, some of us are heeding her advice and engaging in more challenging activities to keep those brain cells stimulated.

  • Get On Your Feet…Get Up and Make it Happen! May 10, 2011
    Listening to NPR this week, I heard a story on the dangers of too much sitting,” Sitting All Day: Worse For You Than You Might Think” that reminded me of Baby Boomer, Gloria Estefan’s great song, Get On Your Feet.  So many of us have sedentary jobs and/or we come home from work (whether required […]
  • Tweet This January 25, 2011
    Having recently viewed the popular highly regarded film, The Social Network, it got me thinking about my use of computer technology and how much I personally depend on social networking to stay in touch with friends and family.  I remember when the Internet was still referred to as the Information Superhighway and dial-up modems were the […]
  • ‘Tis the Season to be Reading December 9, 2010
    It’s that time of year again! Families are coming together to visit and remember past holidays and traditions. Some of us are lucky enough to live close to our children and grandchildren, but there are those of us who aren’t so fortunate. We want to keep in touch and be more involved in our loved […]
  • Cooking Light (and Veg!) for the Holidays November 22, 2010
    I love the smell, taste, and feel of fall – the crisp, clean air, the warmth of vegetables roasting in my oven, and getting cozy with a steaming hot cup of cocoa and a book.  Fall is also a time of holidays and for many of us Boomers, a season of abundant eating and quality […]
  • Rich Retirement – Smart Retirement November 14, 2010
    It’s time for a round-up of recent magazine offerings on the topic of retirement, a chief concern of most Baby Boomers I know. Money Magazine’s October 2010 issue includes their Retirement Guide 2011. Penelope Wang’s cover story, “Seven Secrets to a Richer Retirement,” examines the latest research in the field of behavioral finance (a blend […]
  • How to be an Empowered Patient November 5, 2010
    Mick Jagger probably said it best, “What a drag it is getting old.” Eyesight gets blurry, knees go bad, back goes out, menopause hits…and let’s not forget hypertension, diabetes, arthritis, and a host of other chronic health problems. As we Baby Boomers age, we usually make more visits to the doctor. According to Centers for […]
  • Film Festivals Part Deux – AFI Fest October 30, 2010
    It hardly seems possible that it’s been a full year since we posted about the pleasures of attending film festivals.   One of the biggest and best, the AFI Fest, is about to begin this coming week. AFI Fest is Los Angeles’ longest running international film festival and the 2010 event will be held in Hollywood, California, November […]
  • Conquer Your Inner Hoarder! October 26, 2010
    I’ve become fascinated with the hoarding shows on television. A&E offers Hoarders and TLC airs Hoarding: Buried Alive. The basic premise of both shows is that hoarding is a type of obsessive compulsive disorder whereby people become incapable of throwing out anything, and I mean anything: broken hangers, empty soda cans, and the hoarders’ classic, […] […]
  • Boomers Got a Bum Rap? October 22, 2010
    The October issue of Atlantic Magazine features a provocative cover story focusing on the Baby Boomer generation and their responsibility for and contributions to the country’s present situation. Whether you agree or disagree, Michael Kinsley has written an essay that will make you think. The issue also includes response commentaries from “experts.” Personal […]

    Cathy Guisewite has penned the final panel of that forever dieting, forever shoe-shopping, forever everywoman, Cathy. For more than 30 years, Cathy was the picture of the stressed-out career woman trying to juggle love, work, body issues, mother-daughter relationships, and whatever else modern society threw at her. Cathy ran in 900 newspapers, won an Emmy [… […]
