Researchers have found that people who have two copies of a specific gene almost all develop signs of Alzheimer's disease, which could represent a distinct genetic form of the condition. While scientists knew the gene APOE4 was linked to an increased risk for Alzheimer's, a new study suggests that for people carrying two copies of the gene, it's an underlying cause of it. Published in Nature Medicine, the study also found that individuals with two copies of the gene develop the disease earlier than people with other variants of the APOE gene. Alzheimer’s disease is the most common form of deme...

The eyes can reveal a lot about the health of our brain. Indeed, problems with the eyes can be one of the earliest signs of cognitive decline. Our latest study shows that a loss of visual sensitivity can predict dementia 12 years before it is diagnosed. Our research was based on 8,623 healthy people in Norfolk, England, who were followed up for many years. By the end of the study, 537 participants had developed dementia, so we could see what factors might have preceded this diagnosis. At the start of the study, we asked participants to take a visual sensitivity test. For the test, they had to ...

A longitudinal study of older adults has shown that individuals with higher concentrations of amyloid beta proteins in their brains experienced accelerated cognitive decline. This finding suggests that a single positron emission tomography (PET) scan assessing amyloid beta protein levels in the brain could be sufficient to predict the rate of cognitive decline in individuals. The study was published in the journal NeuroImage: Clinical. Amyloid beta (Aβ) plaques are protein deposits that accumulate in the brains of individuals with Alzheimer’s disease and, to a lesser extent, in several other t...

Older individuals experiencing a faster reduction in the volume of the hippocampus region of the brain also exhibited quicker cognitive decline, according to new research. This correlation did not rely on the accumulation of abnormal proteins in the brain. The findings were published in the journal Neurology. Cognitive abilities undergo significant changes throughout the human lifespan. In childhood, these skills develop rapidly, while in adulthood, they generally stabilize. Typically, humans reach their peak cognitive performance in their late 20s to early 30s. As adults transition into middl...

A recent study published in the journal Neurologyprovides evidence that individuals engaged in cognitively stimulating occupations throughout their midlife — specifically their 30s through 60s — are less likely to develop mild cognitive impairment (MCI) and dementia after the age of 70. This research underscores the potential of mental engagement at work to bolster cognitive function well into old age, marking a significant advance by employing objective data to substantiate these findings. Mild cognitive impairment (MCI) is a condition characterized by a noticeable decline in cognitive abilit...
