Researchers have been able to detect "markers" in the blood that identify the disease three to five years before any memory loss occurs.The breakthrough means that treatment for the disease could be started before irreversible brain damage has been caused – dramatically slowing down progression.The same technology could also make it easier to spot other disease such as Parkinson's and hard-to-detect cancers, said the researchers.Around 750,000 people in the UK suffer from dementia, more than half of whom have Alzheimer's.At present the only way for sure to know if someone has suffered from the condition is to carry out a brain examination after their death.
