Do you want to know how mentally sharp you are? Get your 'brain care score' in just 5 minutes.

Maintaining the health of the brain is crucial for preventing severe health issues that can impact the body's vital organ.

Dr. Jonathan Rosand, a professor of neurology at Harvard University, specializes in treating patients with head trauma, spinal cord injuries, and strokes at Massachusetts General Hospital. He collaborated with a team of researchers to develop a system that assesses brain health, known as the Brain Care Score.

Rosand, in an interview with CNBC Make It, shared that she frequently receives questions from patients and their families about how to maintain brain health and prevent conditions like stroke and memory loss, which have affected their family members.

Exploring opportunities for primary prevention of dementia, stroke, and depression through modifying risk factors like lifestyle choices is important.

Completing a five-minute quiz that inquires about your dietary habits, blood pressure levels, and social relationships can determine the healthiness of your brain.

The test asks questions about your daily behaviors and current health status like:

• What is your resting blood pressure?
• Do you smoke?
• Do you engage in at least 150 minutes of moderate physical activity or 75 minutes of high-intensity physical activity on a weekly basis?
• Do you get less than 7 hours of sleep each night or suffer from untreated sleep disorders?
• Do you struggle to cope with stress, or do you find it manageable?

A lower risk of dementia, depression, and stroke is linked to a higher Brain Care Score, according to a study in Frontiers in Psychiatry. Meanwhile, a paper in Neurology has confirmed the associations between a high Brain Care Score and a lower risk of developing brain diseases.

Rosand recommends enhancing your brain health by focusing on strengthening one of your weaker areas.

""In the beginning, you should start with whatever is most appealing to you, whether it's improving sleep or reducing alcohol intake," he advises."

Improving your performance in one area is likely to result in better performance in other areas, as they are interconnected.

Individuals with a family history of these diseases can still improve their scores.

Rosand states that a recently published study examined individuals with a high genetic risk for dementia and found that increasing your score could lower your genetic risk.

Here are the areas that the Brain Care Score considers:

• Blood pressure
• Blood sugar
• Cholesterol
• Body Mass Index
• Nutrition
• Alcohol intake
• Tobacco use
• Aerobic activities
• Sleep
• Stress
• Social relationships
• Meaning in life

Rosand advises using the score as a guide to improve it, but to do so in a way that suits the individual's needs and preferences.

"Bringing the score and having a clear goal in mind when visiting the doctor is highly beneficial."
