Electrical brain stimulation can boost memory function in older people

(Photo: Pixabay/The Digital Artist) LONDON: Electrical brain stimulation using a non-invasive cap can help boost older people’s mental scores to those of people 20 to 30 years younger, according to a study published on Monday (Apr 8). The research, published in the journal Nature Neuroscience, found that age-related decline in working memory can be reversed … Read more

Syncing brain waves may fight age-related memory problems

Memory can deteriorate naturally, due to age, and even when this process is not related to neurodegenerative conditions, such as Alzheimer’s, it can still affect a person’s quality of life. Now, researchers from Boston University in Massachusetts are exploring ways of fighting age-related memory decline. By resynchronizing brain waves, we could reverse some age-related memory … Read more

Researchers discover neural patterns key to understanding disorders such as PTSD

Credit: CC0 Public Domain Researchers at the University of California, Irvine have identified for the first time an imbalance in a key neural pathway that explains how some people reactivate negative emotional memories. The finding could help scientists unlock new ways to treat psychiatric disorders such as post-traumatic stress disorder. The study, “Multiplexing of Theta … Read more

Mental health can impact memory decades later

New research from the United Kingdom has found that people who experience recurrent episodes of depression throughout adulthood are more at risk of developing memory problems later in life. Accumulated depression and anxiety can predict a person’s likelihood of developing memory problems. Scientists have already shown that depression and other mental health problems can affect … Read more

Brain zaps boost memory in people over 60, study finds

This Friday, April 5, 2019 photo provided by Boston University shows a cap that administers electrical stimulation and monitors brain waves for a visual working memory test at one of the school’s laboratories. A study released on Monday, April 8, 2019, finds that zapping the brains of people over 60 with a mild electrical current … Read more

Could eating garlic reduce aging-related memory problems?

Oral allyl sulfide administration reduces the age-related memory problem through restoration gut bacteria in the intestine (rNDNF= recombinant neuronal-derived natriuretic factor).
