In addition to doing physical exercise, we must practice brain exercise. A combination of exercise and cognitive training (CECT) is more effective than either intervention alone. The present systematic review and meta-analysis were conducted to evaluate the effect of CECT on working memory in the elderly. The current meta-analysis showed that the effects of CECT on working memory in the elderly are moderated by the frequency of the intervention and cognitive status. CECT showed significant positive improvements in working memory in both healthy individuals and those with MCI.

These results are in line with previous studies showing that CECT improves general cognitive function and executive function. In the current study, low-frequency interventions were significantly beneficial for working memory compared to high-frequency interventions. While there is a general consensus that higher training frequency leads to greater benefits, the results of the current meta-analysis found that the low-frequency intervention is more than three times more effective than the high-frequency intervention. Some previous studies have also indicated that high-frequency interventions are less effective than low-frequency interventions suggesting that high-frequency interventions may cause cognitive fatigue in older people.

Cognitive and motor tasks show overlapping activity in the PFC, basal ganglia and cerebellum, suggesting the recruitment of shared neural resources [20]. A review of neuroimaging findings showed that this overlapping activity extends to brain regions involved in motor planning and preparation (secondary motor regions), which are recruited even when working memory tasks do not require overt movement or brain activation. the primary motor cortex [21]. Interactions between these regions increase with the task. In addition to neurocognitive mechanisms, exercise causes changes in the concentration of neuroendocrine markers related to cognitive development in children and adolescents. Neurotrophins, such as brain-derived neurotrophic factor (BDNF) and insulin-like growth factor-1 (IGF-1), have gained much attention due to their contributions to neural circuit development and function. Depending on the stage of development, these neurotrophins have different functions. While BDNF mainly regulates synaptic

At the link 10 EASY BRAIN EXERCISES TO IMPROVE YOUR MEMORY

Your best bet is all kinds of different things that exercise your brain in different ways. “Variety is great,” says Dr. Scharre. “The more you do with your brain, usually the better it is.” This list of exercises for your brain can help you get started. One of the exercises is meditation. In one study, people with mild cognitive impairment or mild Alzheimer's disease who did 30 minutes of guided meditation every day for six months showed slower degeneration in crucial areas of the brain than people who didn't. New to meditation? We researched a ton of meditation apps and compiled a list of the best ones to help reduce anxiety.
