Scientists say they have identified a new genetic form of Alzheimer’s disease

But scientists now believe 95% of people who are over 65 and carry two copies of APOE4 show early signs of the disease, making it a distinct genetic form of Alzheimer’s

Researchers in the US said almost all of the people who carry two copies of the APOE4 gene variant, known as APOE4 homozygotes, are likely to develop signs of the neurological condition.

Scientists say they have identified a new genetic form of Alzheimer’s disease that underscores the urgent need for developing specialised treatment and prevention strategies.
