Both Parkinson's and Dementia with Lewy Bodies mostly occur without family history, so the test may not say much anyway.
In my mom's case I wonder about a viral infection she had in her eye. It was quite severe.
- criddell 6y ago> mostly occur without family history Does that suggest it's environmental rather than genetic?
- maxerickson 6y agoI don't know really. I think the cutting edge opinion is that it isn't known why they occur.
- inglor_cz 6y agoEven genetic diseases sometimes need environmental influences to develop. For example, some people are prone to alcoholism in a hereditary way. But if they live in a society that has zero alcohol, they won't ever become alcoholic. Upon moving to a society where alcohol is sold freely and frequently, they may sink into alcoholism without having any obviously alcoholic ancestor.
- DoreenMichele 6y agoNot necessarily. A homozygous recessive disorder often occurs without prior family history. Two carriers have a child together, the child has the disorder, this is how they learn they are carriers.
