Doctors have yet to figure out what exactly causes the dreaded Alzheimer’s Disease. However, they may be one stop closer in determining a key player in its development: a very common virus. According to a study, which the journal Neuron recently published, there is strong evidence that suggests that two strains of the human herpes virus, more precisely 6A and 7, may play a big role in this condition that rubs people of their memory and not only. According to official reports, in the United States, someone develops Alzheimer’s every 65 seconds.
By midcentury, people are expected t develop this condition every 33 seconds. By that time, the costs of care might run into trillions of dollars. This is mostly why experts are trying so hard to understand this disease and find out what precisely causes it. They’re hope is to find either a cure or at least a treatment that is a lot more effective. In the top ten United States causes of death, Alzheimer’s is the only one that doesn’t have a significant treatment. So, in order to reach this conclusion, the authors of the study compared the brains of 622 people affected by the disease with those of 322 healthy people. What they found shocked them.
The herpes virus might play a part in Alzheimer’s
According to the study, the brains of the people with Alzheimer’s had herpes virus levels that were twice in comparison with the brains of the healthy people. It’s interesting that for years, experts have suspected common viruses to play a big part in the development of this condition. There is an important theory according to which, Alzheimer’s gets triggered in the brain as a response to injury from a virus. Nobody knows for sure whether or not these theories are true. However, they were surprised by the results and will continue to make efforts to find out more about this condition.
