Can a Few Hours of Brain Training Today Protect Your Brain for Decades?
A groundbreaking 20-year study reveals a surprising link between short bursts of cognitive speed training and a significantly reduced risk of dementia. The research, published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions, suggests that as little as 8 to 10 hours of targeted brain exercise, coupled with booster sessions, can offer lasting protection against cognitive decline.
The Power of Speed Training
The study, involving over 2,800 healthy older adults, focused on “speed of processing” training – exercises designed to sharpen the brain’s ability to quickly and accurately process visual information. Participants who engaged in this type of training showed a roughly 25% lower risk of dementia diagnosis over the following two decades compared to those who didn’t receive the training. This finding is particularly notable because the training period was relatively short, and the benefits persisted for an extended period.
Pro Tip: The key isn’t necessarily about memorization or complex reasoning, but about enhancing the speed at which your brain can process information. This type of training appears to build a cognitive reserve, making the brain more resilient to age-related changes.
How Does It Work? Implicit Learning and the “Bike-Riding Brain”
Researchers believe the benefits stem from a process called implicit learning – the acquisition of skills without conscious awareness. As Henry Mahncke, CEO of BrainHQ’s parent company, Posit Science, explains, it’s similar to learning to ride a bike. “You can learn to ride a bike in about 10 hours of training,” he says. “And even if you don’t practice for the next 20 years, you [will] still have ‘a bike-riding brain.'” The speed training exercises, like those offered by BrainHQ, continually increase in difficulty, forcing the brain to adapt and improve its processing speed.
Real-Life Impact: George Kovach’s Story
George Kovach, 74, is a testament to the potential benefits. He began cognitive speed training a decade ago and has completed over 1,300 sessions. “I was interested in taking care of my neurons,” Kovach says, noting that he feels his brain is working better than ever. He combines the training with a healthy lifestyle, including regular exercise and a heart-healthy diet.
Future Research: The PACT Study
Building on the ACTIVE study, the Preventing Alzheimer’s with Cognitive Training (PACT) study is now underway, involving 7,500 participants over the age of 65. PACT investigates the effects of a more extensive training regimen – 45 sessions over several years – to determine if increased dosage leads to even greater cognitive benefits. Results are expected around 2028.
Beyond Training: A Holistic Approach to Brain Health
While cognitive training shows promise, experts emphasize the importance of a holistic approach to brain health. This includes regular physical exercise, a nutritious diet, sufficient sleep, and continued social engagement. These lifestyle factors work synergistically to protect cognitive function and reduce the risk of dementia.
Frequently Asked Questions
- How long does the training necessitate to be? The initial study showed benefits from 8-10 hourlong sessions, plus booster sessions.
- What type of training is most effective? Speed-of-processing training appears to be the most impactful, focusing on quick and accurate visual processing.
- Is this a cure for dementia? No, it’s a preventative measure that can reduce the risk of developing dementia, but it doesn’t guarantee protection.
- Where can I find these types of brain training programs? BrainHQ is one example, but other programs may also offer similar exercises.
Did you know? The benefits of cognitive training can last for decades, even after the training period has ended.
