Risk factors for dementia -

There are several risk factors of dementia that we cannot change, such as age and genetics. These factors do not cause dementia, and it’s certainly not a standard part of aging, however they can make it more likely.

Eat a healthy diet -

A healthy diet can help prevent a variety of different illnesses, including diabetes and dementia, but it can also help to keep your cholesterol and blood pressure in check.

New reseach -

New research suggests that lowering bad cholesterol levels may significantly lessen the risk of dementia by 26%. LDL-C, or low-density lipoprotein cholesterol, also known as ‘bad cholesterol,’ is the culprit when it comes to developing cardiovascular diseases, as well as dementia, later in life. People who have low levels of LDL-C in their blood appear to have a lower risk of having dementia overall.

Eat a balanced diet -

Eating only leafy greens isn’t going to sustain you. It’s not enough to just eat healthy, you also need to eat a balanced diet.

Make sure you’re getting the appropriate amount of fiber during the day. Eat healthy portions of fruit and vegetables daily, protein several times a week, and drink a lot of water.

How to do it -

Stick to the recommended drinking limit during the week, and include several alcohol-free days. You should try not to go over 14 units in a week.

Stay social -

It’s been suggested that loneliness and social isolation could be big factors when it comes to dementia, so creating and maintaining meaningful connections are important to counteract that.

How to do it -

This doesn’t mean that you have to strike up a conversation with everyone you see. Try cultivating face-to-face relationships. This can be done through joining clubs, volunteering, or taking group classes.

Keep your mind active -

Numerous studies have suggested that stimulating the brain is one of the main factors in reducing the likelihood of mental decline.

How to do it -

Regularly challenge yourself. This could mean something simple such as a puzzle, a crossword, or a brain teaser, or you could try for a longer-term activity such as learning a new language or skill.

Sleep well -

It should be no surprise to anyone at this point that sleep is one of the best things we can do to keep ourselves healthy, both physically and mentally.

How to do it -

Create a sleep schedule, meaning get up and go to bed at roughly the same times. You can also encourage sleep by avoiding screens before bed or by creating a relaxing bedtime ritual. If you find that you’re still having trouble, go see a specialist right away.

Quit smoking -

Smoking doesn’t just cause lung cancer—it can also raise your blood pressure and affect your circulation, which can impact the blood vessels in the brain.

How to do it -

There are a variety of ways to quit smoking, but there is no one-size-fits-all solution. Talk to your doctor to figure out the right way for you to quit if you find your motivation flagging.

Treat depression -

Depression has been theorized as both a risk factor and a symptom when it comes to dementia. It can directly affect your ability to do other cognition-positive activities such as sleeping well and staying social.

How to do it -

If you notice that you’re showing signs of depression, talk to your doctor or to a therapist. They can better recommend next steps, which may include therapy or medication.

Keep learning -

Studies have suggested that education may have a sway on future dementia. One study stated that approximately 8% of dementia cases may be linked to leaving education before secondary school.

How to do it -

Keep learning! This doesn’t necessarily mean in a classroom. Take a class online or at your local college if you’d like, or take lessons to learn a new hobby.

Protect your brain -

Head injuries, perhaps not shockingly, can lead to a loss of cognitive abilities. While some things may happen unpredictably, there are certain precautions you can take to prevent these types of injuries.

© Shutterstock

How to do it -

The obvious methods are to wear a helmet when suggested, and to wear your seatbelt in the car. Less obvious, however, is working on coordination and balance exercises, so you’re less likely to accidentally fall. Activities such as yoga and tai chi fall into this category.

Keep an eye on your health -

There are several health issues that we have mentioned throughout this gallery that can potentially impact dementia in the future, such as heart health, blood pressure, and depression. The longer these go on, the more likely they are to have a lasting impact.

How to do it -

Check in with yourself regularly. That doesn’t just mean regular visits to the doctor, though those are also very important. It means taking a mental evaluation of yourself, making sure you are physically and emotionally stable.
