By Sam Elliott-Gibbs Scientists have discovered new genetic variants that could be linked to Alzheimer’s, bringing fresh hope for a possible cure. Researchers in the US discovered 17 genetic strains that might affect the risk of developing Alzheimer’s, the most common type of dementia affecting over 55 million people worldwide. This breakthrough was made using whole genome sequencing and identified the significant variants with Alzheimer’s disease in five genomic regions. The discovery could lead to new ways to treat and prevent this brain-wasting disease. Alzheimer’s is the fifth leading caus…
