Intensive memory training improved source memory and increased cortical thickness in older adults. This suggests that cognitive training can induce structural brain plasticity in the aging brain.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Gerontology
Background:
- Brain plasticity is well-documented in younger individuals.
- The impact of cognitive training on macrostructural brain changes in older adults remains less understood.
- Mental stimulation may offer a cognitive reserve against brain aging.
Purpose of the Study:
- To investigate the short-term effects of memory training on cognition and brain structure in middle-aged and elderly individuals.
- To determine if intensive cognitive training can induce structural brain changes in older adults.
- To explore the relationship between structural brain changes and memory performance improvements.
Main Methods:
- An 8-week memory training program using the Method of Loci (MoL) was administered to one group.
- A control group received no intervention.
- Magnetic resonance imaging (MRI) was used to measure cortical thickness changes pre- and post-intervention, alongside memory testing.
Main Results:
- Memory training significantly improved source memory performance.
- Participants in the memory training group exhibited regional increases in cortical thickness compared to controls.
- Improvements in cortical thickness in specific brain regions correlated with enhanced source memory recall.
Conclusions:
- Systematic mental exercise can induce short-term structural brain changes in the aging human brain.
- These findings demonstrate structural brain plasticity in elderly individuals.
- Further longitudinal studies are necessary to confirm long-term structural alterations from cognitive training.
