🏃 The Role of Physical Activity in Dementia Prevention: How Movement Protects the Brain?
🏃 The Role of Physical Activity in Dementia Prevention: How Movement Protects the Brain? ❤ This is a post worth sharing with loved ones of all ages! Dementia, or acquired cognitive decline, is one of the major challenges facing modern gerontology and public health. According to WHO data, the number of people living with dementia could reach 152 million by 2050. Traditionally, clinical medicine has focused on pharmacological treatment of established dementia, but current medications only temporarily alleviate symptoms. ❗ Contrary to the common myth of inevitable cognitive decline in old age, modern science views dementia as largely preventable. Up to 40 % of dementia cases can be prevented by addressing risk factors, including: low education level, hypertension, diabetes, obesity, depression, smoking, social isolation, and — high on the list — physical inactivity (hypodynamia). Physical activity is the most accessible and effective tool for dementia prevention! 🧠 How does movement protect the brain? For a long time, it was believed that adult neurons do not regenerate. However, the discovery of neurogenesis in the hippocampus — the area most affected in Alzheimer’s disease — radically changed this paradigm. Physical activity has proven to be one of the most powerful stimuli for the formation of new neurons: 🔹 stimulates the formation of new neurons; 🔹 improves blood supply to the brain; 🔹 reduces inflammation and levels of harmful proteins linked to Alzheimer’s; 🔹 lowers dementia risk by 28–40 %. ❓ What types of activity work best? Not all movement is equally beneficial. Here are the key principles: 🔹 Aerobic exercise (walking, swimming, cycling) — 150 minutes per week at moderate intensity. Regularity is key! 🔹 Strength training (with resistance bands, dumbbells, or body weight) — 2–3 times a week: 8–10 exercises, 2–3 sets of 10–15 repetitions. 🔹 Balance and coordination (yoga, dancing) — especially useful at early signs of cognitive decline, as they require simultaneous work of both brain and body. The strongest effect comes from a combined programme: aerobic + strength + neuromotor training. ❗ Important note! Physical activity should be manageable. Extreme exertion may increase the risk of micro‑strokes and heart rhythm disorders. 🏃 Practical steps: 🔹 Start as early as possible — age 40–60 is critical. 🔹 Use a pedometer or fitness tracker — this doubles adherence. Your goal: 8 000–10 000 steps a day, with at least 3 000 at a brisk pace. If it’s hard at first, work up to this gradually. 🔹 Group activities combine movement and social interaction, reducing dementia risk by another 12–15 %. 🔹 Overcoming barriers for older adults (fear of falls, joint pain): alternative options include water‑based exercise or seated workouts for those with limited mobility. ❗ No current medication demonstrates results comparable to regular physical activity. Even moderate changes — a daily 30‑minute brisk walk, taking the stairs instead of the elevator, morning exercises — can delay cognitive aging by 5–10 years! The recipe for dementia prevention is simple and accessible to everyone: move today to keep your brain young tomorrow! ✅ This post was created as part of a week of awareness on the importance of physical activity.
