Research is continuing into genetics of dementia. Certain types are more likely to be passed down in genes than others. For example see yesterday’s prompt where Familiar Alzheimer’s disease where offspring of someone with the gene have a 50% chance of developing. Whereas vascular dementia which is caused by damages to blood vessels is more affected by lifestyle factors. Although conditions like high blood pressure or diabetes which can increase risk of dementia can themselves be passed down genetically therefore inheritance of dementia is complex.
