Data from the population-based Finnish Cardiovascular Risk Factors, Aging and Incidence of Dementia (CAIDE) study has revealed that healthy dietary choices in midlife may prevent dementia in later years. Out of 2,000 participants, 1,449 took part in the follow-up.

A mouse study has found that mice (genetically engineered for Alzheimer’s) who were sleep deprived for eight weeks, not only showed significant cognitive impairment, but also showed a significant increase in the amount of tau protein that became phosphorylated and formed tangles.

Data from 1.1 million young Swedish men (conscription information taken at age 18) has shown that those with poorer cardiovascular fitness were 2.5 times more likely to develop early-onset dementia later in life and 3.5 times more likely to develop mild cognitive impairment, while those with a l

Data from 1,425 cognitively healthy older adults (70-89) has found that a diagnosis of chronic obstructive pulmonary disease (COPD) was associated with an 83% greater risk of developing non-amnestic mild cognitive impairment.

We know that the E4 variant of the APOE gene greatly increases the risk of developing Alzheimer’s disease, but the reason is a little more mysterious. It has been thought that it makes it easier for amyloid plaques to form because it produces a protein that binds to amyloid beta.

I’ve talked before about the evidence linking diabetes to an increased risk of Alzheimer’s disease, but now a new study suggests that elevated blood sugar levels increase Alzheimer’s risk even in those without diabetes, even in those without ‘pre-diabetes’.

A study involving nearly 6,000 African American older adults has found those with a specific gene variant have almost double the risk of developing late-onset Alzheimer’s disease compared with African Americans who lack the variant.

Providing some support for the finding I recently reported — that problems with semantic knowledge in those with mild cognitive impairment (
