A neurologist has revealed six “lesser-known” strategies we can all employ to lower our risk of dementia. According to the expert, sticking to these methods could help significantly protect your brain as you get older.

Dementia currently affects around 900,000 people in the UK. However, this number is expected to rise with our ageing population.

The syndrome is more common in people over the age of 65, yet age is not the only risk factor for developing it.

Research has actually shown that 40% of dementia cases could be prevented by making certain changes to your lifestyle.

With this in mind, an expert took to social media platform TikTok to explain more. US-based neurologist Doctor Baibing Chen, who is best known online as Dr Bing, said: “If you want to protect your brain from dementia, it starts with what you do today.

“Dementia isn't just something that comes with age, there are real ways to reduce your risk, and keep your brain healthy for years to come. You've probably heard of regular exercising and eating a healthy diet to prevent dementia. But here are some lesser-known strategies to protect your brain.”

Get your hearing checked

According to Dr Bing, hearing loss is one of the “most overlooked” risk factors for dementia. “Even mild hearing loss can significantly increase your risk,” he said.

“If you're having trouble hearing don't wait, get it checked out and consider hearing aids if needed. It's about more than just hearing, it's about keeping your brain engaged and active.”

Get good quality sleep 

Dr Bing recommended getting seven to nine hours of quality sleep every night. He continued: “Sleep is when your brain clears out toxins and repairs itself. Poor sleep can increase your risk of dementia. If you have sleep apnoea, make sure that's being treated.”

Stay social 

You social life can have an effect on your risk of dementia. “Isolation is a risk factor for dementia and staying connected with friends, family and your community whether it's a weekly call or spending time with your loved ones, social engagement keeps your brain sharp,” he said.

Learning new skills and challenging your mind

Dr Bing said this is “essential” for brain health. He said: “Whether it’s picking up a new language or learning to play an instrument, keeping your mind active creates new brain connections, the more you challenge your brain, the better you can fend off cognitive decline.”

Protect your head

This may seem “obvious” but head injuries can “significantly increase” the risk of dementia. “Whether you're biking, skiing or playing sports, wear helmets to protect your brain from trauma,” he said. “Even minor head injuries can have long-term effects.”

Maintain good oral health

Finally, he added: “This might be surprising to some people but gum disease and poor dental health are linked to a higher risk of dementia. Infections in the mouth can lead to inflammation, which affects the brain over time. So keep up with regular brushing, flossing and dental visits.”
