Researchers from the University of Oslo in Norway studied how memory changes as people get older. They wanted to find out if memory loss happens to everyone the same way. They looked at a large amount of data from 3,737 healthy people over several years. This included 10,343 brain scans and 13,460 memory tests.
Their findings were complex. The hippocampus, a part of the brain important for memory, was key to understanding memory loss. They found that as people age, especially over 60, changes in the brain affect memory more. Those with a specific gene linked to Alzheimer’s disease showed faster memory decline.
The research shows that memory loss is not only due to aging. It is related to individual differences in brain health. Treatments to help slow memory loss may need to focus on many areas of the brain. Starting these treatments early might be best.
Overall, the study suggests memory loss is a broad issue related to many factors over time. It may help researchers identify people at risk and improve care for brain health. The research appears in the journal Nature Communications.
