University of Limerick scientists have been awarded €5.4 million to develop a nanoscope which will allow the screening of patient cells for Alzheimer’s disease. In Ireland, over 44,000 people are affected by Alzheimer's and other forms of dementia. There are 7.7 million new cases of dementia each year worldwide, implying that there is a new case of dementia somewhere in the world every four seconds. At present there is no test to screen for this disease.
