How do I protect my memory?

Many of the same habits that protect the heart also protect the brain. A large Finnish trial showed that combining them can help.

What the experts agree on

  • Exercise regularly, especially aerobic exercise, which supports memory and mood.
  • Combine habits: activity, a healthy diet, keeping your mind busy and social life work better together.
  • Keep blood pressure and blood sugar in check with your doctor.
  • Sleep well and stay socially active.
  • For women, the menopause years matter for the brain; talk to your doctor about your options.

Where they disagree

  • Supplements: some core experts take many; Topol and the FINGER trial rely on lifestyle alone.

The specialists

What the core experts do

Peter Attia

  • Regular dry sauna (Outlive cites about 4 × 20 min a week at 80 °C or more, linked in Finnish studies to lower dementia risk)Some evidence
  • Sees ketogenic eating as a possible alternative brain fuel in early cognitive decline, based on small trialsSome evidence

Andrew Huberman

  • Focused work in 90-minute blocks with distractions removedPersonal habit
  • Takes omega-3 EPA for brain health, mood and focusSome evidence

Rhonda Patrick

  • Push hard enough to raise lactate: hard exercise raises BDNF, a growth factor linked to learning and mood (human evidence still early)Some evidence

Stacy Sims

  • Creatine for brain fog and mood; she cites a trial where 5 g a day added to an antidepressant helped women with depressionSome evidence
  • Favours truly hard intervals over moderate or zone 2 cardio for midlife cognitive and metabolic benefitsSome evidence

Mary Claire Haver

  • Points to observational data linking longer lifetime oestrogen exposure, including hormone therapy, with better cognition; not a licensed reason to start hormonesDoctor only
