A new study has revealed that half of UK adults cannot name a single dementia risk factor. If asked, how many could you name? The study by Alzheimer's Research UK found that just 1% of UK adults could name the seven known dementia risk or protective factors. Heavy drinking, smoking, genetics, high blood pressure, depression and diabetes are the six dementia risk factors, while physical exercise is a protective factor. According to the study, more than half of UK adults know someone with dementia, yet only half also recognised that the disease is a cause of death. Furthermore, a fifth of people quizzed for the report incorrectly said that dementia is an inevitable part of getting old. Right now, there are more than 850,000 people in the UK living with dementia and that number is expected to top one million by 2025. Alzheimer's disease is the most common type of dementia, accounting for around two-thirds of all cases. Hilary Evans, chief executive of Alzheimer’s Research UK, said: “It is a sad truth that more people are affected by dementia than ever before and half of us now know someone with the condition. Yet despite growing dementia awareness, we must work harder to improve understanding of the diseases that cause it.” You can read the full Alzheimer’s Research UK report here: https://www.dementiastatistics.org/wp-content/uploads/2019/02/Dementia-Attitudes-Monitor-Wave-1-Report.pdf#zoom=100
Genetics, lifestyle and environmental factors are all thought to play a role in causing Alzheimer’s disease. And it’s now looking increasingly likely that we can add certain strains of the herpes virus to that list too. A study funded by the National Institutes of Health, the results of which were recently published in the journal Neuron, found that people with Alzheimer’s disease had higher levels of herpes strains 6A and 7 – two common forms of the virus, but not the ones responsible for genital herpes or cold sores. Alzheimer’s – also commonly referred to as dementia – causes people to lose their memory and is the sixth leading cause of death in the United States today. The authors of the study hope their research could one day lead to exciting new Alzheimer’s treatments and help better determine just who is at risk of developing the disease. "The hypothesis that viruses play a part in brain disease is not new, but this is the first study to provide strong evidence based on unbiased approaches and large data sets that lends support to this line of inquiry," National Institute of Aging Director Richard J. Hodes, M.D., said in a statement. The findings of the study reignite an old theory that suggests viruses could impact brain functions long term.
