BrainHQ.

BrainHQ, which was developed based on the work of Mike Merzenich, who is one of the godfathers of learning and neuroplasticity, right?

And they...

do various tasks primarily focused on developing and maintaining processing speed.

Some of that evidence goes all the way back to an older trial called ACTIV that was done in the US in the 90s.

It was still the biggest ever trial of like pure cognitive brain training.

Again, in older adults, so 60s and 70s, they had three different training groups and then a control group.

The training groups did memory training and kind of like, you know, mnemonics, memory palaces, that kind of stuff to help them remember.

There was reasoning training, which is kind of like looking for patterns in numbers and letters.

And then there was processing speed training, where in this example is visual processing speed.

So things flash up on a screen.

in increasingly small increments, so it could be hundreds of milliseconds.

And as you get better at doing it, that time gets shorter.

And you have to remember what you saw and where you saw it on a screen.

They just published a secondary analysis of the ACTIV trial that showed that those who did processing speed training with booster sessions at one and three years had a significantly decreased risk of dementia 20 years later.

And they've done some other studies showing that that kind of training improves cholinergic signaling in the forebrain, which we know is susceptible to the processes of dementia.

So in particular, it's this training to be able to improve either visual or auditory processing speed, which is not something that...

as you get older, you tend to not do activities that require you to process information quickly.

Like driving is probably the main one, but you can do it in sports and music and other scenarios.

But if you're not doing those things, processing speed tends to drop off sometime around 60 years old.
