A new study has found Alzheimer’s - which disproportionately affects women - could be prevented by gender-based personalised medicine.

       The lead author of the study, Dr Richard Isaacson, of Florida Atlantic University, says that women account for two-in-three patients - with incidence twice as high even after accounting for longer lifespans.

       "Population-attributable risk models suggest that managing risk factors can prevent up to one-third of dementia cases, highlighting the immense potential that lies in addressing modifiable risk factors,” Dr Isaacson says.
