Brains and Bodies work together!
By Amy Price PhD
Your brain care how your body lives. Maybe it is time to redecorate from the inside out!
New research on cognition that shows transfer of training and increase in quality of life can be very successful when individual differences are professionally assessed and programs targeted to individuals. This is why one size fits all ‘brain training’ shows limited success. The brain requires novelty and positively graded accomplishment to reach full potential. [1-4].
Brain age related deficits are noticed primarily in the prefrontal and parietal cortical regions which tend to shrink as individuals age with men exhibiting more extensive shrinkage than women [5]. These areas are crucial for planning and for connecting input from other brain areas. The areas of shrinkage initially demonstrate increased regional activation. This may be a time sensitive window where neuroplasticity growth factors can be leveraged to best advantage. Combining several strands of behavioral and neuro-imaging evidence, the argument can be made that functional plasticity has the capacity to alter the course of cognitive aging. Losses in regional brain integrity may drive functional reorganization through changes in processing strategies and domain specific cognitive training.
These same deficits can be present in brain injured persons but the route to successful training would take a different though just as effective path.
Factors such as cognitive training, regular exercise, nutrition enrichment and positive relationships can increase Cortical thickness . These findings were first published on animal studies but are also noted in human studies [5-10]. A combination targeted personalized brain and physical training produces specific volume changes in white and grey matter [9]
Physical exercise boosts the brain’s rate of neurogenesis throughout life, while mental exercise increases the rate at which those new brain cells survive and make functional connections into existing neural networks.[7-10] Both physical exercise and the challenge from mental exercise increase the secretion of nerve growth factor, which helps neurons grow and stay healthy.[8-10] This makes sense if we think of how exercise helps to clean out the sludge and provide oxygen so the body can make more effective use of tissues needed for regeneration and repair. In fact scientists are now finding compounds that can increase our stem cells within the body and even then are finding that targeted solutions are needed for optimum stem cell growth health and production [14]
Nyberg found that although older brains exhibit less plasticity than do young brains overall, the benefits of training—particularly domain-specific training—can be substantial and durable [13]. Studies are showing these gains to be of 5 years + More- over, the training benefits were found to be similar to the amount of decline anticipated over 7–14 years [3, 12, and 13].
