Five Key Strategies to Boost Brain Health and Reduce Dementia Risk, According to Expert

Maintaining brain health is increasingly important as we age, just as much as taking care of our physical health. The brain is a vital organ for overall health and quality of life. According to the World Health Organization, approximately 57 million people worldwide were living with dementia in 2021. Dementia is defined as a neurocognitive disorder that affects memory, thinking, and daily activities.

Lifestyle habits play a critical role in supporting brain function and protecting against conditions like memory loss. Professor Jonathan Schott, a neurologist at University College London and Chief Medical Officer at Alzheimer’s Research UK, shared five key strategies to improve brain health and reduce the risk of dementia.

2. Regular Physical Exercise

Physical exercise is essential for supporting brain health. Schott recommends exercise that raises the heart rate for at least 20 minutes, three to four times a week. Regular exercise improves overall health by balancing blood pressure, cholesterol, and body weight. “Chemicals released from muscles are thought to affect the brain and change its structure,” he explains. High-intensity exercise isn’t necessary; even simple walks can strengthen brain function. Schott notes, “Small but consistent activities throughout life are among the most beneficial.” Research from 2023 shows that even walking fewer than 4,000 steps a day can have positive effects on brain health, making it a more achievable goal.

3. Strong Social Connections

Strong social relationships are critical for brain health. A 2023 study found that a lack of social interaction can lead to volume loss in the hippocampus and a decline in cognitive performance, potentially increasing the risk of neurological diseases like Alzheimer’s. Schott advises, “Stay connected with loved ones and engage in social activities you enjoy.”

4. Managing Blood Pressure

Blood pressure is important not only for heart health but also for brain health. Schott recommends regular blood pressure checks, especially for individuals in their 30s and 40s. High blood pressure can strain brain vessels, leading to cerebrovascular diseases and dementia. “Lowering blood pressure strengthens blood vessels and reduces the risk of blockages and bleeding,” he adds.

5. Focusing on Enjoyable Activities

Schott emphasizes the importance of focusing on activities that bring joy. For example, if someone doesn’t enjoy Sudoku, they should engage in other mentally stimulating activities they find enjoyable. Activities that are enjoyable keep the brain more active and enhance cognitive function.

Conclusion

The five strategies recommended by Professor Schott aim to support brain health and improve quality of life. Challenging the brain with new experiences, regular physical exercise, maintaining strong social connections, managing blood pressure, and focusing on enjoyable activities are practical methods that can be easily integrated into daily life. These steps not only protect cognitive function but also help guard against diseases like dementia.
