Dementia Not Just for the Elderly: Doctor Highlights Critical Age for Blood Pressure Control to Protect Brain Health

Dementia is not solely a condition that affects the elderly, and proactive prevention is essential, according to US online doctor Leonid Kim.

When symptoms appear, brain pathology may have already been ongoing for many years.

Kim explained that by the time clinical symptoms manifest, brain pathology may have been progressing silently for years. Therefore, he stressed that individuals should not wait until memory noticeably declines to begin dementia prevention efforts. Controlling blood pressure during critical age periods is vital for establishing a brain defense.

International medical journal The Lancet has also highlighted the link between lifestyle, chronic disease management, and dementia risk. Early adjustments can significantly lower future illness risk. Kim noted that while genetics can play a role, they do not predetermine the onset of the disease. The brain constantly receives signals from diet, exercise, sleep, and habits, offering opportunities to build a protective shield.

Therefore, if you want to prevent dementia, you cannot wait until memory has significantly declined before starting.

Key strategies include prioritizing sleep for the brain's cleaning system, engaging in daily physical activity to activate brain growth signals, and managing vascular health. Kim specifically warned that high blood pressure, high blood sugar, or chronic inflammation can lead to vascular degeneration, impairing the brain's oxygen and nutrient supply and increasing the risk of white matter lesions and vascular dementia. He emphasized that vascular damage accumulates over decades, making mid-life (ages 40-50) blood pressure control a critical defense.

Controlling blood pressure at a critical age can establish a defense line for the brain.

Furthermore, Kim underscored the importance of cognitive reserve, built through lifelong learning, challenging new activities, and forming diverse neural connections. This creates alternative pathways, potentially delaying cognitive decline even if some brain areas degenerate. Activities like reading, learning new skills, and racket sports stimulate the brain. Kim concluded that preventing dementia requires a multifaceted approach, focusing on sleep, exercise, vascular management, and social learning, with mid-life management of blood pressure, blood sugar, and sleep being particularly impactful for long-term brain health.

The brain has a cleaning pathway called the 'glymphatic system' that primarily operates during deep sleep to help clear metabolic waste, including beta-amyloid protein associated with Alzheimer's disease.
