Dementia symptoms – do you smell that? It could signal brain decline

Other risk factors

According to the Alzheimer’s Society, there are a few studies that suggest birth relatives of a family member with DLB may be at slightly higher risk, but this is not conclusive.

“There are only a few known families in which DLB seems to follow a strong inheritance pattern and no mutations have so far been identified,” says the health body.

As it explains, several gene variants have recently been linked to a higher risk of DLB.

“The APOE e4 variant is thought to be the strongest genetic risk factor for DLB, as it is for Alzheimer’s disease,” it adds.
