The problem this solves

Brain health and mental health share most of the same upstream inputs — sleep, movement, social connection, metabolic control, stress regulation — and most of the same downstream costs. What protects cognition over decades and what protects mood and resilience year-to-year are largely the same investments.

This micro-course covers the foundational practices that compound: sleep, exercise, social connection, blood-sugar stability, hearing care, and the early-warning signs worth taking seriously. It treats mental health as both an outcome (how you feel) and an input (how clearly you can think), and it's honest about which interventions have strong evidence vs which are emerging.

A taste of the exercise

The preview lesson walks you through scoring yourself on the modifiable factors and picking the single one most likely to move the needle in your specific case.

Key concepts

Glymphatic clearance
The brain's overnight waste-removal system, active during deep sleep. Chronic short sleep reduces clearance of metabolic waste including amyloid-beta.
BDNF (brain-derived neurotrophic factor)
A growth factor for neurons, elevated by aerobic exercise. Plausible mechanism for the cognitive benefits of cardio.
Cognitive reserve
The brain's capacity to compensate for pathology. Built by education, mentally demanding work, social engagement, and physical activity over decades.
Modifiable dementia risk factors
The Lancet Commission identifies ~12-14 factors that, addressed across a lifetime, could potentially reduce dementia incidence by ~30-40%.
Mood-cognition loop
Low mood reduces cognitive function, which reduces capacity to act, which can deepen low mood. Interrupting the loop usually requires action on both ends.

Common mistakes

  1. Treating brain health as a 70-year-old problem and ignoring midlife inputs.
  2. Buying nootropic stacks while sleep is under six hours.
  3. Ignoring hearing loss because hearing aids feel like an old-person thing.
  4. Letting friendships atrophy through midlife.
  5. Treating mental health as separate from physical health.
  6. Self-medicating with alcohol and underestimating its cognitive cost.

FAQ

Can dementia really be prevented?
Risk-reduced, not prevented. The Lancet Commission framework suggests 30-40% of cases are potentially modifiable through addressing 12-14 lifestyle and environmental factors. That's significant but not a guarantee.
Are brain-training apps useful?
Evidence is weak that they generalise beyond ‘getting better at the app.’ Time is better spent on cardiovascular exercise, strength training, sleep, and social connection.
How does sleep specifically affect brain health?
Deep sleep is when the glymphatic system clears metabolic waste from brain tissue. Chronic short sleep is associated with measurably higher amyloid burden across decades. We'd label this as strong evidence for the direction.
What about supplements?
Omega-3 has partial support; magnesium glycinate helps some; B-vitamins matter for deficiency states. None substitutes for sleep, exercise, social connection, and metabolic health. Talk to a clinician before adding anything if you're on medication.
When should I worry about my memory?
Occasional forgetfulness is normal. New-onset persistent difficulty with familiar tasks, navigation, recent events, or planning warrants a clinical assessment. Earlier evaluation produces more options.
