" New evidence suggests that the cold sore virus is linked to Alzheimer&amp;#039;s disease, researchers have said. The herpes simplex virus, HSV-1, is carried by the majority of elderly people and previous research has suggested that it is present in the brains of up to 70 per cent of Alzheimer&amp;#039;s patients. Now, scientists at Manchester University have found that infected cultures of human brain cells contain dramatically elevated levels of amyloid beta protein, which builds the deposits found in the brains of people with Alzheimer&amp;#039;s disease. Dr Ruth Itzhaki, the researcher who led the study, told New Scientist magazine: &amp;#039;This strongly suggests that the virus produces amyloid protein and, ultimately, plaques in Alzheimer&amp;#039;s brains.&amp;#039; Professor Clive Ballard, director of research at the Alzheimer&amp;#039;s Society, told BBC News that a link between the herpes simplex virus and the brain disease was first proposed ten years ago. &amp;#039;More research is needed before we can establish how relevant it may be to the treatment of people with Alzheimer&amp;#039;s disease,&amp;#039; he said. \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
