If your mother had early-onset dementia, you might be wondering about your own risk. Let’s break it down in simple terms.
Early-onset dementia, which occurs before age 65, can sometimes run in families. However, having a parent with this condition doesn’t necessarily mean you’ll develop it too.
For most people with early-onset Alzheimer’s, the most common form of dementia, genetics play a role in only about 10-15% of cases[1]. These rare cases are caused by specific gene mutations that can be inherited from a parent[3].
If your mother had one of these genetic mutations, you would have a 50% chance of inheriting it[1]. But remember, even if you inherit the gene, it doesn’t guarantee you’ll develop dementia – it just increases your risk.
For the majority of early-onset dementia cases, the exact cause isn’t known. Other factors like lifestyle and environment likely play a role too[1].
It’s worth noting that having a parent with early-onset dementia does increase your overall risk compared to someone without a family history. However, this increased risk is still relatively small[5].
If you’re concerned, you can talk to your doctor about genetic testing. But keep in mind that these tests can’t predict with certainty whether you’ll develop dementia[1].
The good news is that there are things you can do to potentially lower your risk, regardless of your family history. These include staying physically active, eating a healthy diet, keeping your mind engaged, and managing conditions like high blood pressure and diabetes[7].
Remember, even if you have a higher genetic risk, it doesn’t mean dementia is inevitable. Many people with genetic risk factors never develop the condition[5].
Ultimately, while your mother’s condition might increase your risk slightly, it’s just one piece of a complex puzzle. Focus on the things you can control, like maintaining a healthy lifestyle, and don’t hesitate to discuss any concerns with your healthcare provider.
