How does exercise impact dementia risk according to recent studies?

Regular exercise, particularly aerobic activities, has been shown to reduce dementia risk by 35% in middle-aged Britons, according to a 2022 study.

What is the link between head injuries and dementia?

Head injuries, even those that may not show immediate effects, can increase dementia risk two to three-fold by triggering the production of abnormal proteins linked to Alzheimer's.

Can social isolation increase dementia risk?

Yes, people who are socially isolated and lonely are 60% more likely to develop dementia, highlighting the importance of maintaining social interactions.

Boost Brain Health: Simple Lifestyle Changes Fight Dementia

A sedentary lifestyle is strongly linked to major dementia risk factors like obesity and heart disease. However, regular physical activity, particularly aerobic exercise like jogging or dancing, offers powerful protection. A 2022 study revealed that Britons who exercised regularly had a 35% lower chance of developing dementia.

Exercise delivers more nutrients to the brain and stimulates 'brain fertiliser' proteins that promote neuron growth and strengthen memory areas. Even 30 minutes of slightly breathless activity can significantly boost these essential proteins. Importantly, exercises that improve balance can help prevent falls, thus reducing the risk of head injuries.

Head injuries, even minor ones, can double or triple dementia risk by triggering abnormal protein production associated with Alzheimer's. Therefore, wearing helmets during activities like cycling is vital. Breathing polluted air also elevates dementia risk by 10% due to PM2.5 particles that can reach the brain.
