It seems every day there are more conditions “blamed” to be causing a disease. Dementia and Alzheimer’s disease is a part of this. Genetics play a key role in dementia risk and genetics accounts for about one in every four seniors. Certain genes can experience a mutation (change in protein structure) that can cause the condition. If you have some genetic history, it is important to get checked out. There are tests in the market to help you govern if you have a genetic mutation that can lead to dementia, so be sure to ask your doctor or healthcare provider.
