Is frontaltemporal dementia hereditary? my mom has it, but no other relatives (dad, grandparents, aunts/uncles) have had it.

Can well be : Although precise hereditary data is lacking due to the variable nature of many ftd presentations, it is thought that 20% may be associated with a mutation affecting chromosome 17, and there may be at least 4 different allelic presentations.

Some risk: Typically 20-50% of people with frontotemporal dementia will have a 1st degree relative (sibling, parent, or child), any.

Hereditary FTD: Check out http://memory.Ucsf.Edu/ftd/overview/biology/genetics/multiple/ftd for some info re hereditary ftd. While we can't prevent it, much less even predict who will "get" it, optimal health & weight appear to go a long ways towards maintaining brain health. Also, taking care of your heart appears to help take care of your brain. So healthy eating plus regular exercise are key.

Small component: Most types of frontal temporal lobe dementia have a small genetic component. Some of the rare types have a significant genetic component but without other family history this is very unlikely.
