How your blood type might be linked to brain health

New preliminary research has shown that those with ‘Type O’ blood have larger ‘grey-matter’ volumes in the cerebellum, a region of the brain important in assisting with motor skills and cognitive function.

Grey matter is largely composed of brain cells including neurons and is important for processing information around the brain. It is suggested that larger grey matter is associated with better brain function and may be a protective factor against Alzheimer’s disease but this claim is yet to be confirmed.

Update: the role of a good night’s sleep in dementia risk reduction

New research has reiterated that a good night’s sleep may be one of the keys in reducing your risk of dementia, particularly Alzheimer’s disease.

Researchers from UC Berkeley, USA published results in the Journal Nature Neuroscience which suggest that sleep deficit may be a channel through which amyloid beta proteins (a major hallmark of Alzheimer’s disease) are triggered and cause the onset of Alzheimer’s disease symptoms.

What are the effects of playing video games on the brain?

Playing video games is an extremely popular pastime. If we add up all the hours spent by people who play video games (gaming) each week, it would equal over 3 billion hours. On average it is suggested a teenager can spend nearly 10,000 hours gaming by the time they are 21. So what does this do to the brain?

Green tea and its link to dementia risk

New research suggests that high consumption of green tea may reduce your risk of dementia. However, it is important to note that this result is based on a preliminary study consisting of just under 500 participants and the result is yet to be published in a peer-reviewed scientific journal.

Where did this claim come from?

This result was recently presented at Alzheimer’s Disease and Parkinson’s Disease Conference in Nice, France by researchers from the Kanazawa University Graduate School of Medical Science in Japan.

Could your Body Mass Index (BMI) be linked to dementia risk?

New research looking at close to 2 million UK medical health records has suggested that your BMI might be linked to dementia risk. The results reiterate that being underweight could increase your risk of dementia, as previously stated on the Alzheimer's Australia Your Brain Matters dementia risk reduction website.

The MIND diet: another approach to dementia risk reduction

Dietary patterns have long been associated with decreasing cognitive decline and reducing your risk of dementia and researchers have now suggested that those who follow the MIND diet can lower their dementia risk by as much as 50%.

Could dairy products have a positive effect on brain health?

Recent research has suggested that drinking milk and consuming other dairy products (such as cheese, yoghurt, cream etc) might have more benefits than just making your bones strong.

Published in the American Journal of Clinical Nutrition, researchers from the University of Kansas Medical Centre, USA wanted to test the hypothesis of whether dairy food consumption is associated with increased levels of cerebral glutathione in older adults.
