The APOE gene, or the “forgetting gene,” has been proven to influence Alzheimer’s risk. So a team of scientists is exploring the effect of gene therapy on people with the riskiest version of the gene.

If it works, the pay-off could be huge.

Gene therapy involves transplanting specific genetic material into human cells in order to correct genetic problems, and is typically attempted on diseases with a singular cause. Alzheimer’s doesn’t seem to have one singular cause — but since the risk of developing it is so strongly associated with the APOE gene, it’s certainly worth a try.
