How to prevent increasing dementia: These are the ways to reduce the risk

The number of dementia (memory loss) patients is increasing worldwide. According to the World Health Organization (WHO), dementia is currently the seventh leading cause of death globally. It is considered a major problem for mental health. Due to the growing number of dementia cases, experts predict that by 2050, 153 million people will be at risk of this disease, which is three times more than the current number.

Since this disease predominantly increases with old age, many people consider it an age-related illness. The risk of dementia is higher in people over the age of 65. Those with high blood pressure, diabetes, obesity, smoking habits, excessive alcohol consumption, physical inactivity, depression, and those living in isolation are more likely to fall prey to this disease.

Currently, over 55 million people worldwide suffer from dementia. More than 60% of them live in low- and middle-income countries, according to the WHO. Every year, nearly 10 million new cases are reported.

Dementia is not just a mental health issue but also a brain disease, making it highly dangerous. Alzheimer’s disease is considered the most common form of dementia, accounting for 60-70% of the cases.

In 2019, dementia cost the global economy approximately 1.3 trillion USD, with around 50% of that cost relying on informal caregivers, such as family members and close friends. Dementia affects women more than men, and 70% of caregiving time is provided by women, according to reports.

Although there has been slow progress in the treatment of this disease, advancements in understanding the complex nature of the brain and how dementia develops continue to evolve. Developing drugs that can cross the blood-brain barrier remains a challenge.

Experts say that while waiting for a cure, there are ways to reduce the risk of dementia. They believe that one day, scientists will achieve success in treating this disease. In the meantime, adopting brain-strengthening habits can help prevent dementia. Here are some effective methods:

Keep Your Eyes Active:

Vision is one of the most important senses for humans, and it’s commonly accepted that our eyes are highly complex structures capable of distinguishing around 10 million colors. Among the animal kingdom, human vision is considered one of the sharpest. Research shows that good vision is closely linked to cognitive health, especially in old age. A recent scientific study reported that changes in visual sensitivity could indicate signs of dementia up to 12 years before formal diagnosis. Keeping your eyes engaged helps activate the brain.

Continuous Learning:

The impact of education on health is multifaceted and complex, but one thing is clear: higher and quality education is linked to better health outcomes. In the context of dementia, the more time spent in education, the lower the risk of developing dementia. Therefore, continuous learning, even in old age, can help reduce the risk of dementia.

Social Engagement:

Being lonely is harmful to health and increases the risk of diseases. Scientific research shows that long-term loneliness can increase the risk of dementia by about 60%. Socializing and staying connected with others can reduce this risk.

Stay Alert, Not Neurotic:

Personality plays a significant role in health outcomes. High levels of alertness and lower levels of neuroticism are associated with a reduced risk of dementia, according to studies.

Reduce Air Pollution:

Research has shown that air pollution can also increase the risk of dementia. Reducing air pollution where you live and avoiding polluted environments is essential for lowering the risk.

Prioritize Sleep:

Sleep problems are directly linked to dementia symptoms. Good sleep helps maintain brain health and keeps the body energized. Prioritizing sleep is essential to prevent dementia. Those who get enough quality sleep are less likely to develop dementia.

Exercise and a Healthy Diet:

Just as mental activities are important, physical exercise and a healthy diet also help keep the brain and heart healthy. Incorporating regular exercise into daily life is vital, and avoiding smoking and excessive drinking while maintaining a healthy diet can reduce the risk of not only dementia but many other diseases as well.
