Dementia prevention and early detection through biomarkers and lifestyle

Global health experts and researchers are emphasizing the importance of early dementia detection and lifestyle interventions. According to data from Roche, up to 75 percent of dementia cases worldwide remain undiagnosed, affecting a global population of more than 55 million people.

Advancements in diagnostic technology, specifically blood tests for biomarkers such as pTau217 and pTau181, are emerging as alternatives to more invasive procedures like lumbar punctures or PET scans. These tests allow for quicker routine examinations within primary care settings. The US FDA has already authorized a combined blood test for symptomatic adults aged 55 and older.

In addition to medical diagnostics, the World Health Organization (WHO) has highlighted that many dementia risk factors are manageable through lifestyle changes. Key preventative measures include regular physical activity, a balanced diet, managing conditions like hypertension and diabetes, ensuring adequate sleep, and reducing stress, smoking, and alcohol consumption. Social engagement and mental stimulation are also noted as vital components for maintaining cognitive health.
