Taiwan has entered a super-aged society, and dementia has become a growing issue. The prevalence of dementia among people aged 65 and above across Taiwan is about 7.99%, and the number is estimated to rise to 680,000 people in 15 years. The medical community has proposed a "comprehensive brain health guide" that integrates observation of early warning signs, precise diagnosis, and care, while strengthening support for aging in place through cross-team collaboration.

Medical teams pointed out that dementia is the result of long-term accumulation, and the line of defense should be moved forward to the stage of "mild cognitive impairment (MCI)". Although patients show declines in memory or cognition, they are still able to manage daily life independently. About 10% to 15% may progress to dementia each year. Early intervention can help slow deterioration.

Clinical findings also show that many family members regard early changes as normal aging and therefore delay seeking medical attention. Emotional changes, difficulty expressing oneself, and slower gait are all warning signs. Early examination is recommended to understand the condition through methods such as blood tests and brain imaging, and to assess possible treatment options.

In daily prevention, diet and exercise are equally crucial. Research shows that the nutrients in citrus fruits and berries help reduce the risk of cognitive decline. Exercise is recommended to combine aerobic activity and strength training, together with cognitive activities, in order to enhance brain plasticity.

The medical community has proposed the "321 brain health principle", including 3 dietary directions - balanced intake of multicolored fruits and vegetables, high-quality protein, and healthy fats, while reducing processed foods; 2 types of exercise - combining aerobic exercise and strength training, together with cognitive training; and 1 core concept - cultivating cognitive resilience and strengthening the foundation of brain health through good sleep and stress management.

Medical teams said that the accumulation of daily habits and early intervention can help delay decline and maintain quality of life.
