There’s More than One Risk factor of Alzheimer’s Disease

Alzheimer’s disease continues to afflict over four million Americans, with that number predicted to greatly increase over the next few years. While we all are familiar with the major symptoms of the disease, like memory loss and confusion, what isn’t clear is what really causes them in the first place. Scientists now believe that there are various factors that might put people at risk for developing this progressive disease.

Predetermined Risk Factors

The greatest known risk factor of Alzheimer’s disease is age. The majority of people who develop Alzheimer’s are 65 or older. And for those over the age of 85, the risk of suffering from the disease is now about 50%.

Heredity is another key risk factor for Alzheimer’s disease. Scientists have discovered that genes do play a part in those with the disease. Some of these genes suggest that someone might get Alzheimer’s (but not that they definitely will), while other more determining genes definitely do lead to a person developing Alzheimer’s. These genes, however, are very rare, accounting for only about 5% of all Alzheimer’s cases.

And along the same lines, a person’s family history can put them at risk. Those who have a close family member with Alzheimer’s stand a greater chance of developing it themselves, and the risk continues to increase if more than one family member has Alzheimer’s. Genetics could be at work here, but environmental factors may also play a role.

Controllable Risk Factors

Our family history, genetics, and the fact that we are aging are all outside of our control. There are some risk factors now being studied, however, that we can exercise some control over.

Scientists are beginning to think that serious head injuries are a potential risk factor for Alzheimer’s disease. While these can’t always be prevented, taking precautions when you are involved in sports and taking care not to fall outside or in your home is a good idea.

Your heart’s health can also be a risk factor of Alzheimer’s disease. There is evidence that heart disease can affect your brain’s health. So taking preventative measures to prevent high blood pressure, high cholesterol and diabetes can also protect you from developing Alzheimer’s in the future.

A lack of physical and mental activity can also be a risk factor for Alzheimer’s disease. Exercise and mental stimulation are important for living a vibrant life anyway, and if they can help prevent Alzheimer’s, it’s all the more reason to make sure they are a regular part of your life.

It’s important to be aware of the various factors that put one at risk for developing Alzheimer’s. Being aware of any predetermined risk factors and developing healthy habits are both good strategies.
