Fact 3: Factors Contributing to MCI and Dementia
MCI and dementia don’t arise out of nowhere. They are often the result of a complex interplay of multiple risk factors. Understanding these risk factors is crucial in mitigating the onset of these conditions and managing their progression once they have developed.
Age is perhaps the most well-known risk factor, with the incidence of both MCI and dementia rising significantly as individuals advance in years. The risk of developing these conditions doubles approximately every five years after age 65.
However, age isn’t the only player in this arena. Genetics also have a significant role. Individuals with a family history of MCI or dementia, particularly Alzheimer’s disease, are at a higher risk. Certain genetic mutations have been identified that can increase the probability of developing these conditions.
Lifestyle factors are another major contributor. Physical inactivity, tobacco use, unhealthy diet, and harmful use of alcohol are all linked to an increased risk of MCI and dementia. It’s essential to note that these factors are often interconnected, each one potentially exacerbating the others, creating a cumulative effect on an individual’s cognitive health. (3)
