At this point, genetic factors have been linked more to the underlying causes of vascular dementia. This can also help to answer the query be is vascular dementia hereditary. Vascular dementia and genes Alzheimeraposs Society Mutations in a gene called NOTCH cause a rare form of vascular dementia known as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL ). It is one of the most common heritable cause of vascular dementia. Alzheimeraposs Society In most cases, vascular dementia itself is not inherited.
CADASIL is inherited in a simple, single-gene pattern like familial Alzheimeraposs disease.

Other than in a few, very rare cases, parents cannot pass on vascular dementia to their children. Being the second most common type, vascular dementia does not appear to be linked to genetics in most cases, however, researchers are still looking for risk genes.
