Brain Training Reduces Dementia Risk by 25%, Study Finds

A 20-year NIH-funded study found booster sessions of computerized visual speed training cut dementia risk by 25% in older adults, with 2,800 participants across six U.S. states.

  • On Monday, the ACTIVE trial follow-up published in the journal Alzheimer's & Dementia found `Double Decision`, the speed-training exercise, lowered dementia risk by 25% over 20 years.
  • Researchers say speed training enhances visual processing speed and attention, while investigators propose its `Double Decision` adaptive design drives procedural learning and neuroplasticity.
  • More than 2,800 adults aged 65 and older were randomized across six US geographic sites, training one to two 60–75-minute weekly sessions for five weeks plus booster sessions, with dementia tracked via Medicare medical records.
  • Yet study authors and outside researchers cautioned that the benefit applies only to this specific training, with Marilyn Albert saying `To me, this changes the conversation`.
  • The Lancet Commission two years ago concluded nearly half of dementias could be prevented by addressing 14 risk factors, as Posit Science commercializes speed training amid conflict-of-interest disclosures.
