PHILADELPHIA (KYW Newsradio) — As baby boomers age, a growing number are starting to express anxiety about developing Alzheimer's. After all, if an older family member had Alzheimer's, there may be a risk.
But it's important to know that a risk is just that: it's not a guarantee.
The age of onset is also important. People with close relatives struck by dementia early — before age 65 -- are more likely to be susceptible genetically.
There are options to be tested to see if you are at greater risk, but researchers at Northwestern University's Feinberg School of Medicine strongly suggest having an in-depth discussion with a genetic counselor if you're considering a test.
And remember: there are things we all can do if we think we are at risk such as modifying our lifestyle.
Studies have shown that physical inactivity, hearing loss, depression, obesity, hypertension, smoking, social isolation, diabetes and low education levels raise the risk of dementia.
All of these factors are modifiable.
