Is Lewy body hereditary?

A growing body of evidence suggests genetics may play a role in the disorder and that some cases may be inherited. Scientists have found that some of these rare cases can be caused by mutations in the gene for alpha-synuclein (SNCA), the main protein found in Lewy bodies.

Is Lewy body disease inherited?

When dementia with Lewy bodies is caused by SNCA or SNCB gene mutations, it is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder. In these cases, an affected person usually has one parent with the condition.

What is the main cause of dementia with Lewy bodies?

What causes dementia with Lewy bodies? Dementia with Lewy bodies is caused by deposits of an abnormal protein called Lewy bodies inside brain cells. These deposits, which are also found in people with Parkinson's disease, build up in areas of the brain responsible for things such as memory and muscle movement.

Is Alzheimer's inherited from mother or father?

We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.

How do you get Lewy bodies?

Scientists aren't sure what makes Lewy bodies start to build up in the brain. They're also not sure why some people get LBD and others don't. Some health conditions worsen your odds of getting the condition. People with Parkinson's disease or REM sleep behavior disorder have a higher risk of LBD.

Can a person with Lewy body dementia live alone?

Because there is no cure, treatment for LBD is about symptom management. If you have LBD, live alone, and want to remain independent for as long as possible, it's important to establish a plan that will help you to care for yourself. Here are nine ways to live well with LBD: Be Informed.
