Similarity in damage due to Alzheimer's Disease in Twins
Researchers found that twin pairs had similar progressions of Alzheimer’s Disease (AD) and dementia prior to death and even they also had similar combinations of pathogenesis in two or more unconnected areas of damage to the brain. This unique study was conducted by international team of researchers led by USC psychologist Margaret Gatz.

Novel biological markers have discovered by researchers from Finland and Estonia that are strongly indicative of risk of dying from any disease within the near future. Blood samples from over 17000 generally healthy people were screened for more than a hundred different biomolecules. The health status of these study volunteers was followed for several years. The researchers looked for measures in the blood that could reflect who had died within the following 5 years after the blood sample was taken. In a study published in PLOS Medicine, they describe identification of four such biomarkers of death.
