Research finds that non-invasive brain stimulation can improve the cognitive and physical health of the elderly

Memory ability, especially the episodic memory ability that remembers specific details of recent events, will decline rapidly with age.

In view of the inconsistent results of the current research on whether tDCS can improve the episodic memory of the elderly, the researchers first carried out a meta-analysis study to provide a quantitative assessment of the effect of tDCS on the episodic memory function of the elderly.

Based on meta-analysis showing that tDCS can improve memory decline in the elderly, the research further explores the mechanism behind it through functional magnetic resonance (fMRI).

Previous studies have found that even if the elderly can achieve the same memory performance as the young, the age difference can often be observed at the level of neural activity, that is, the elderly use the compensation mechanism.

The tDCS study found that brain stimulation can improve the memory performance of the elderly by increasing the level of neural activity in the extraction stage, but it is still unanswerable whether this neural plasticity further enhances the unique compensation mechanism of the elderly, or is it common to the elderly and the young Neural activity has been enhanced.

To answer this question, the research team conducted an rTMS intervention study.

In addition, in the physical health level, especially cardiovascular-related health indicators, compared with the control group, the elderly in the rTMS intervention group showed a significant reduction in blood lipid levels, including total cholesterol (CHO) and triglycerides (TG).

The team’s series of studies have shown that non-invasive brain stimulation can "rejuvenate" the brains of healthy elderly people, and can be used as an effective means to improve the memory and blood lipid metabolism of the elderly, and improve the cognitive and physical health of the elderly in the brain.
