This is the Health Report
Some kinds of mental skills naturally decrease
As people get older
Yet research seems to show that some training
Can improve such skills
A recently published study also appears to demonstrate
That the good effects of training can last for many years
After that training has ended
Researchers at Johns Hopkins University in Maryland
Wanted to learn how long memory and thinking skills
Would last in older people who trained to keep them
The people were part of the ten-year research project
They were taught methods meant to improve their memory
Thinking and ability to perform everyday tasks
More than 2800 volunteered for the study called ACTIVE
- short for Advanced
Cognitive
Training
For Independent and Vital Elderly
Most studied when they were more than 70 years old
The volunteers took one of several short training classes
Meant to help them keep their mental abilities
One class trained participants in skills
Including how to remember word lists
Another group trained in reasoning
A third group received help with speed-of-processing
- speed of receiving and understanding information
A fourth group - the control group did not get any training
Earlier results had established that the training
Helped the participants for up to five years
Now
Lead study writer George Rebok says
The research showed most of the training
Remained effective a full ten years later
Professor Rebok and his team found that the people
Trained in reasoning and speed-of-processing
Did better on tests than the control group
"We are wondering whether those effects
Which endured over time would still be there
Ten years following the training
And in fact
That's exactly what we found
"
The effect on memory
However
Seemed not to last as long
Still
The old people in any of the three classes
Generally reported less difficulty
In performing daily activities than the control group
The total training time for the older people
Was between 10 and 15 hours
Professor Rebort and his team are now considering ways
To provide such training for lower cost
"We are trying to make the training more broadly available
For example
We have a grant right now
From the National Institute on Aging to try
To make a web-based version of the ACTIVE memory training
And put the training online
"
One question still to be studied
Is how only a few hours of training
Can still be effective after ten years
The study appears in the Journal of the American Geriatrics Society
