Blood-thinning drugs may reduce dementia risk in people with irregular heartbeats
Conclusion If you’ve been diagnosed with AF and you have been prescribed anticoagulant treatments such as warfarin or clopidogrel, we already know they protect you against having a stroke. This study suggests they may also help to protect you against dementia. Cutting the risk of dementia for people who have a raised risk because of AF would be an exciting step forward. Unfortunately, we can’t tell from this study whether the protection against dementia was down to the anticoagulants, because of the possible effect of unmeasured confounding factors. Usually, we would want to see a randomised controlled trial (RCT) to f...

Snoring link to Alzheimer ’s disease unproven
Conclusion This relatively large cross-sectional analysis has found a link between certain measures of breathing problems during sleep and poorer cognitive function in middle-aged to older adults. The strengths of this study include its size and use of a prospective sleep study to assess whether people had sleep apnoea or other problems with breathing during sleep. The use of standard cognitive tests is also a strength. However, the study does have its limitations: The study did have mixed findings – while certain measures of problems with breathing during sleep (e.g. oxygen levels) were associated with cognitive outco...

Heartburn drugs linked to premature death
Conclusion This larger set of observational data finds that PPI drugs are associated with an increase in the risk of early death compared with either H2 blockers or no acid suppression drugs. This was the case for participants both with and without gastrointestinal problems. It also appears as though the longer the PPIs drugs are taken, the greater the risk of death. Considering that these drugs are widely used in the UK, these findings may cause concern. But the research has a number of important limitations: The study was conducted in a population of mostly white, older US male veterans, which might limit the ability...

Reported link between diet drinks and dementia and stroke is weak
Conclusion The researchers used data from a large ongoing cohort study to look for links between consumption of sugary and artificially sweetened drinks and risk of stroke or dementia. This cohort study benefits from the large overall sample size, long period of data collection, careful and valid diagnostic assessments, and adjustments for a number of confounders. However, care must be taken when interpreting these results – particularly if latching on to the maximal tripled risk figures reported in the media. There are several points to consider: Small numbers The new number of strokes and dementia in this study was sma...

Two older drugs could be 'repurposed' to fight dementia
Conclusion This early stage experimental research has demonstrated a beneficial neurological effect of trazodone and dibenzoylmethane on mice with diseases mimicking neurodegenerative diseases. It is important to acknowledge that this is animal research and therefore the drugs might not have the same effect when they are trialled on humans. That being said, trazodone is already an approved drug for depression and sleep problems and has therefore already passed safety tests. If the mechanisms of neurodegeneration in humans and mice are similar, it is possible trazodone could be used in the future in treating Alzheimer's and...

'Tooth loss link to increased risk of dementia'
Conclusion This study adds to the evidence that good oral health is linked to good overall health, including a reduction in the chances of developing dementia in later life. But the research doesn't prove that regular tooth brushing will prevent dementia. We don't know what causes dementia. From research so far, it looks as if there are a number of interlinked causes. Brain health and ageing are likely to be affected by factors including diet, exercise, smoking, alcohol use, blood pressure and genetics. While living a healthy lifestyle may certainly reduce the chances of dementia, there are no guarantees. This study ha...

Calcium supplements linked to post-stroke dementia in women
Conclusion The media paint this as a troubling study for older women who take calcium to strengthen their bones. However the small size of the study (only 98 women took calcium supplements, and only 14 of those got dementia) and its observational nature mean that we cannot rely on the results. As the researchers mention, it is possible that those taking supplements were less healthy than those that didn't in some unmeasured way. Further research may improve our confidence in these results. Broken bones are not a trivial matter for older people – a broken hip can be the difference between being able to live independentl...

Can chocolate make you smarter?
ConclusionStudies suggesting that chocolate is good for us always grab the headlines. However, as is so often the case, the reality is less clear than the headlines suggest.The current study adds to information about the links between diet and brain function – the way our brain processes and manages information. It found that people who scored better than average on these tests said they ate chocolate more often than people who scored worse than average on the tests. But we don't know why that is.There are quite a few limitations to the study. It's cross-sectional, which means we don't know which came first: the chocol...

Link between indigestion drugs and dementia 'inconclusive'
Conclusion This study found people taking PPIs had a 44% higher risk of developing dementia in a seven-year period compared with those not taking the drugs. However, it's not accurate to say this was down to the PPIs – the study couldn't prove this, and there are many possible explanations. For a start, the groups weren't very similar. Those taking PPIs had poorer health, and were more likely to be taking a number of medicines and have conditions linked to a higher risk of dementia, such as diabetes and heart disease. After taking these factors into account in the analysis, the link between PPIs and dementia reduc...

NHS Health Checks 'prevented thousands of heart attacks'
ConclusionThis descriptive study has provided information about how many people took part in the NHS Health Check programme in the first four years it was available. While the uptake was initially relatively low, it is increasing. It is also encouraging that some of the more vulnerable groups – those who are older and those in the most deprived social group – are most likely to attend the checks. There were limitations to the data available. For example, it was not possible to directly assess whether all new prescriptions and treatments after the checks were as a direct result of the checks. The proportion of people wh...

New brain diet 'slows mental decline'
ConclusionThis observational study aimed to investigate the relationship between the MIND diet and its protective properties for mental decline in an older population. The study has several strengths, including the large sample size, long observational period of up to nine years, regular annual assessment of cognitive functions, and comprehensive assessment of diet. However, one of the main limitations is that this type of study cannot show cause and effect – it can only show an association between the diet and slower mental decline. There may be other unmeasured factors that account for the results, such as genetics, ...

Half a handful of nuts a day 'reduces early death risk'
Conclusion This Dutch cohort of middle-aged to elderly adults generally found people were less likely to die in the following 10 years if they ate a small number of nuts a day compared with none. The study has strengths in its large sample size and that cause of death was followed up for the full cohort using valid medical codes. However, there are various points to bear in mind before we jump to the conclusion that nuts are the magic ingredient that will slash our risk of death. No clear trends It is difficult to draw any clear interpretations about how nut consumption may be associated with risk of death overall or fr...

Five-year 'death test' for older adults launched online
Conclusion This large study has identified numerous risk factors associated with a person's risk of death within five years. Researchers used this information to develop an online tool that predicts someone's risk of death within the next five years. The study's strengths include its large sample size and the prospective nature of the study design. But there are some limitations. There may be some bias in the type of people who volunteered to take part. The death rate was lower than that of the average population in this age group, which may indicate that the participants were more interested in their health and so had he...

Air pollution linked to silent strokes
Conclusion This cross-sectional study has suggested a link between exposure to small particles in the air (one form of pollution) and the presence of "silent stroke" in older adults – small areas of damage to the brain tissue that are not severe enough to cause obvious symptoms. There are a number of limitations to be aware of when assessing the results of this study: While there was an association between particulate matter in the air and total brain volume, this was no longer statistically significant after taking into account whether people have conditions such as high blood pressure, which can also affec...

Middle-age spread 'seems to reduce dementia risk'
Conclusion This cohort study of more than 1.9 million UK adults aged over 40 links being overweight or obese to a lower risk of dementia, compared with healthy weight people. Underweight people were at a higher risk of dementia. The study has many strengths, such as its large size and applicability to the UK. However, the authors note their results buck the trend of other research, which found being overweight or obese was linked to an increase risk. They suggest their study is probably more reliable than the past ones as they were smaller. They aren't quite sure what this means, and say: "The reasons for and publi...
