A special device worn on the head that sends electrical charges into the brain may improve the memory abilities of older people. The device may even give them the ability to remember things as well as a person 20 to 30 years younger than them. These are the findings of a study released in the scientific publication Nature Neuroscience earlier this month. Researchers working on the study found that the age-related damage to working memory can be repaired. This is possible, they found, through stimulating two important areas of the brain at a special rhythm. Working memory is the information held temporarily for use in immediate activities such as reasoning and decision-making. The study involved 42 younger adults aged 20 to 29 and 42 older adults aged 60 to 76. The researchers tested all subjects for their performance in a working-memory activity. The findings are still early and only relate to healthy volunteers. But the findings could point to new ways to increase brain operation in older people suffering from diseases that affect these operations, such as dementia and Alzheimer’s patients.
