Cognitive decline: prevention and slowing down
40% of dementias could be prevented by actions on modifiable risk factors. These 7 scientifically validated prevention levers can transform your cognitive trajectory.
The 7 prevention levers
Sleep 7–9h
Memory consolidation, glymphatic cleaning (beta-amyloid elimination). Untreated sleep apnea doubles the risk. Goal: regular hours, cool and dark room.
Physical exercise 30 min/day
BDNF +25%, hippocampal neurogenesis, improved cerebral vascularization. Fast walking, swimming, cycling — moderate to high intensity yields the best neuroprotective results.
Mediterranean diet
Olive oil, fatty fish, colorful vegetables, legumes — 30% risk reduction. Avoid refined sugars, red meats, ultra-processed foods.
Active social engagement
Volunteering, clubs, family, friends — isolation increases the risk of dementia as much as hypertension. Social contact stimulates language, memory, and emotional regulation.
Continuous learning
New language, instrument, courses, demanding reading — strengthens cognitive reserve. The protection coefficient: the higher the reserve, the more the brain can compensate for losses.
Management of chronic stress
Chronic cortisol destroys hippocampal neurons. Meditation, yoga, exercise, strong social relationships — reducing stress is directly neuroprotective.
Control of hypertension, diabetes, cholesterol
Vascular factors are the main modifiable factors for dementia. Blood pressure ≤ 130/80 after 40, HbA1c ≤ 7%, controlled LDL — each factor significantly reduces risk.
Daily cognitive stimulation
30 min/day of games, digital tools, engaging activities — slows decline by 30-50% in Alzheimer's. The 62 DYNSEO tools allow for tailored stimulation at home.

FAQ
Can cognitive decline be prevented?
Partially — 40% of preventable dementias according to The Lancet 2020. Sleep, exercise, Mediterranean diet, social engagement, and continuous learning are the most powerful levers.
Does exercise protect against dementia?
Yes — 30-40% reduction in risk with regular activity. Mechanisms: BDNF, hippocampal neurogenesis, vascularization, anti-inflammation.
What is the role of sleep?
Memory consolidation + glymphatic cleaning (beta-amyloid elimination). Less than 6 hours chronically = +30% risk of dementia.
Conclusion: invest in your brain at any age
Preventing cognitive decline is not a retirement concern — it starts at 30 with lifestyle habits. The 8 levers presented here all have solid evidence and are accessible without a medical prescription. DYNSEO tests allow for tracking the evolution of cognitive functions over time.
