Fact 7: Dementia Can Be Genetically Inherited, but It’s Not Always the Case
It’s natural to worry about inheriting dementia if it runs in the family. While certain types of dementia, such as early-onset Alzheimer’s disease and Huntington’s disease, have a clear genetic link, they are relatively rare. Most people with dementia do not have these genetic forms, and their family members do not necessarily have an increased risk compared to the general population.
In other types of dementia, the genetic influence is more subtle. For instance, having a parent or sibling with Alzheimer’s disease may slightly increase one’s risk, but it doesn’t guarantee they will develop the disease. Factors such as lifestyle and environment also play a significant role.
The complex interplay of genes, lifestyle, and environment is still being studied, and our understanding of the genetic aspects of dementia continues to evolve. However, even if a person has a genetic risk factor for dementia, changes to their lifestyle and regular medical check-ups can help manage their risk and maintain cognitive health.
Dementia’s genetic element is a critical consideration in research and prevention strategies. However, it’s essential not to overlook the multifactorial nature of the disease. The interaction between our genes, lifestyle, and environment contributes to our overall risk, and acknowledging this can empower us to take proactive steps towards maintaining our cognitive health.
