A UK study has shown that in a cohort of older men, individuals experiencing frequent bad dreams were twice as likely to be later diagnosed with Parkinson’s as those who did not. Previous studies have revealed that people with Parkinson’s disease experience nightmares and bad dreams more frequently than adults in the general population. But using [...]
Dietary supplements can slow progression of age-related macular degeneration (AMD), the most common cause of blindness in older Americans. In a new study, US scientists analysed 10 years of Age-Related Eye Disease Studies (AREDS and AREDS2) data. They showed that the AREDS2 supplement formula, which uses antioxidants lutein and zeaxanthin instead of beta-carotene, reduced risk [...]
Mechanisms associated with a particular diabetes drug can also help to protect against Alzheimer’s disease, a study has reported. The results of the Karolinska Institutet study published in Neurology on June 2 indicate that the drug’s target protein can be an interesting candidate for the treatment of Alzheimer’s disease. Alzheimer’s disease is becoming increasingly common, but [...]
New research has uncovered how genetic changes that accumulate slowly in blood stem cells throughout life are likely to be responsible for the dramatic change in blood production after the age of 70. The study, by scientists at the Wellcome Sanger Institute, the Wellcome-MRC Cambridge Stem Cell Institute and collaborators, was published on June 1 [...]
Rochester biologists who study the genetics of lifespan have suggested novel targets to combat ageing and age-related diseases. Natural selection has produced mammals that age at dramatically different rates. Take, for example, naked mole rats - they can live up to 41 years, nearly ten times as long as similar-size rodents such as mice. What [...]
People with Alzheimer’s have more senescent brain cells than those without this disease, a new study shows. Senescent cells, which are damaged cells in the body that do not die off when they should, have been linked to many aspects of ageing and disease. The new results, published in Nature Aging, show that these neurons [...]
Scientists at the University of Michigan Rogel Cancer Center were optimistic when they identified a small molecule that blocked a key pathway in brain tumours. But there was a problem: How to get the inhibitor through the bloodstream and into the brain to reach the tumour. In collaboration with multiple labs, the teams fabricated a [...]
Scientists have proven that normal brain ageing is accelerated by about 26 per cent in people with progressive type two diabetes. The authors of a study published on May 24 in eLife, evaluated the relationship between typical brain ageing and that seen in type two diabetes. They observed that type two diabetes follows a similar [...]
Men with prostate cancer have a 50 per cent higher risk of developing serious and potentially fatal blood clots in the five years after their cancer diagnosis compared with men of the same age without prostate cancer. That's according to new research published in the online journal BMJ Open. Although the level of risk is [...]
Eating cranberries could help to improve memory and brain function, and lower ‘bad’ cholesterol, according to new research. The University of East Anglia study published on May 19 looked at the benefits of consuming the equivalent of a cup of cranberries a day among 50 to 80-year-olds. The research team hope that their findings could have [...]
