Can Meditation Reverse Memory Loss?
Study Shows Improvement on Memory Tests After Practicing Meditation for 8 Weeks
Improvements in Memory continued...
Based on the results, Khalsa hopes the practice may help keep some people's
mild memory problems from progressing to more severe problems, but acknowledges
that once memory becomes too impaired, meditation may not be possible for the
person to do.
Why does it seem to help? ''I use the analogy of going to the gym and
lifting weights for eight weeks," Khalsa says. "You're definitely stronger. I
think we see this in the brain. It's like training the brain. You are somehow
improving the chemical milieu of the brain. Blood flow improves the anatomy of
the brain and it functions better," he says.
A Memory Expert's View
A memory expert, Gary W. Small, MD, director of the Memory & Aging
Research Center at the David Geffen School of Medicine at the University of
California, Los Angeles, had some caveats about the study.
''It's a small study," he tells WebMD. And it needs replication, as do all
Even so, Small says, the results are plausible. "Meditation might help them
focus more," he says of those with memory problems. ''And a big reason people
don't remember things is that they are not paying attention."
Relaxation may play a role, too, he says, as some studies show stress can
lead to brain atrophy, he says.
The speed of the effect of the meditation is not surprising to Small. In
researching his last book, iBrain: Surviving the Technological
Alteration of the Modern Mind, which examines the effect of
technology on the brain, Small found that exposing older people to technology
by having them search the Internet an hour a day changed their brain activity
in one week. He found an increase in frontal lobe activity, in areas that
control short-term memory and decision making, he tells WebMD.
