2. Genetics – The Role of Our Biological Blueprint
Delving further into the risk factors, genetics emerge as a potent player in the risk of dementia. The truth is, our genetic blueprint holds clues about our susceptibility to various diseases, dementia being one of them. For instance, if your family tree reveals instances of dementia, you might be at a higher risk of developing the condition.
The interplay between genetics and dementia is not fully deciphered, but a clear association cannot be denied. There exist certain genes that, when present, may increase the likelihood of developing Alzheimer’s disease, a common form of dementia. The ApoE-e4 gene, for example, is one such genetic marker that has been frequently associated with Alzheimer’s.
However, it’s important to understand that genetics is not destiny. Not everyone who has a family history of dementia or carries dementia-associated genes will develop the condition. Much like age, genetics is just one aspect of the risk. Many other factors – including lifestyle, environmental factors, and comorbid conditions – also play a significant role in determining the risk of dementia. (2)
