US researchers have reported that high levels of bad cholesterol and low levels of good cholesterol are associated with greater amounts of the Alzheimer’s protein, amyloid, in the brain in a group of people at high cardiovascular risk.

A US study suggests that some older people with a history of head injury and loss of consciousness are more likely to have a build-up of amyloid – a hallmark Alzheimer’s protein – in their brains.

Researchers in the US have used brain imaging techniques to identify an area of the brain, called the lateral entorhinal cortex (LEC), that is particularly vulnerable in Alzheimer’s disease.

A group of leading doctors from the G8 countries have penned a letter to the Health Secretary Jeremy Hunt and David Cameron, urging them not to overlook the importance of diet and lifestyle factors in reducing the risk of dementia.

Researchers in the US have suggested that improvements in health may have contributed to a decline in dementia prevalence in certain sections of the population.

A study of over 12,000 people has found that people who lived through a recession in early adulthood or midlife are more likely to have worse cognitive skills in their 50s.

Researchers in the US have linked a measure of high blood pressure, called pulse pressure, to biological signs of Alzheimer’s disease in a group of healthy people aged between 55 and 70.

US researchers have reported that a shorter night’s sleep and poorer quality sleep are associated with higher levels of the Alzheimer’s protein, amyloid, in the brain in healthy older adults

Researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester have shown success with a potential new treatment for prion disease in mice, suggesting it could also hold benefits for the treatment of other neurodegenerative diseases like Alzheimer’s.

Researchers in Japan have developed a new brain scan to detect the build-up of a protein called tau, which is involved in Alzheimer’s and frontotemporal dementia.
