This New Video Game Might Just Defeat Depression

Share

Before you read too much into this headline: no, getting a healthy helping of Mass Effect or World Of Warcraft likely isn't going to do anything for your depression. New science is, however, giving us clues about a very specific type of custom-made video game and its potential role in helping the moods of depressive people. We're still discovering the limits and uses of the games in question, and at the moment the idea has only really been tested on a specific group of people.

But the treatment of depression is expanding, and beyond exercise, therapy, and antidepressants, fighting aliens within a specific interface may hold hope for those of us with depression. And it all has to do with some very interesting problems with the depressed brain.

If you're not naturally a gamer and aren't sure whether this is for you, be comforted by the fact that the people being tested in the studies weren't gamers, either; they were all over 60. There's a reason for that, which I'll elaborate in a minute. The main thing to take away from it, though? Don't be put off this line of scientific enquiry because you've never touched a controller and think Prince Of Persia is about Aladdin. This may be the future of depressive therapy, and we could all use a bit more fun.

How A New Video Game Might Help Depression

The idea of gaming on a screen as a particular help to depressed patients, specifically elderly ones, isn't a new one. Back in 2014, research found that a kind of game called a "neuroplasticity-based computerized cognitive remediation-geriatric depression treatment" (nCCR-GD, in case that made your eyes cross) showed distinct uses when treating low mood in older people who weren't really responding to antidepressant medications. The nCCR-GD games, though, weren't exactly Mario Kart. They were specially designed cognitive challenges involving complicated word lists and images of moving balls across a screen.

The good news was that these games, lacking in narrative or basic fascination though they were, showed good results. As Bustle reported at the time that the games were designed to engage with the "executive functions" of the brain, some of the most complicated of our mental processes. Explaining executive processes can be complicated, but neuroscientist Professor Adele Diamond in the Annual Review of Psychology gives a good working definition:

She also points out that there are three different kinds of executive function: inhibition, working memory, and cognitive flexibility. Inhibition helps us use self-control, working memory keeps information available for us to make decisions, and cognitive flexibility lets us do complex tasks like planning or reasoning. It's this area that the particular games targeted, and new research indicates that this wasn't just a one-off.

What Executive Function Has To Do With Depression

Executive function may sound like an excellent fancy way to look at the brain's complex decision-making, but what has it got to do with depression? A lot, as it turns out. Studies have shown that people with depression have less executive function; one in 1999, for example, gave depressed and non-depressed tasks that would use the three different bits of executive function, and found that they were poorer at all three of them. It's also worse in people with chronic depression than ones with brief episodes.

So how does poor executive function fuel depression? A good outline comes from a review of the science back in 2002 in the French journal L'encephale. The three bits of executive function, the scientists explained, have direct links to problems common to depressive people. If you don't have proper inhibition control, you might take in information that's actually irrelevant and construe it poorly.  If you can't maintain decent short-term memory, you're less able to be able to cope with sudden stressors, and can't get yourself out of depressing situations quickly enough. And if you can't plan properly, you're more likely to be miserable about getting negative feedback on anything, rather than using it as motivation and planning to be better.

It can also be a self-fulfilling cycle. Real problems with executive function, wrote Nordic scientists in 2004, "may have a negative impact on everyday functioning" and fuel further depression: why can't I just make a simple decision? Why is my head so foggy? So is the solution gaming?

Can You Get Your Hands On The Game?

The new study out this week is radically different from the one in 2014. For one, it doesn't make up a game for specific use; it used Project: EVO, by Akili Interactive, a game custom-designed to help neuroscientific outcomes, particularly in areas of executive functioning. It's a game that requires very swift decision-making in a make-believe world, requiring people to pay attention only to specific images and not to others. It's also competitive; as the game progresses and players get more proficient, it gets harder. (It's also cute: one game includes guiding aliens through a canyon and avoiding obstacles.) In 2015 it showed real potential helping the attention of kids with ADHD, and now this research shows it could also be applied to people with depression.

The Project: EVO study was done using people of 60 and over because, the researchers emphasized, being unable to focus because of worries and depression seems to be more of an issue for that age group. They compared people using Project: EVO with others given a standard antidepressant and a control group given a placebo. The results showed that, for people with more than mild depression, EVO provided better results for mood — but they added a necessary note of caution. The video game is meant to be used in conjunction with therapy, and people in the study needed to be monitored to make sure they did it; it wasn't as successful if they were just left to their own devices to download and play it. (Many didn't bother.)

The use of Project: EVO as a therapy is yet to be approved by the FDA, so it's not widely available just yet. And you've got to remember that these studies focused exclusively on the elderly, so the worth of games to people in younger age groups might not be as applicable. More science is needed, but it's entirely possible that one day your therapy prescription will come with a hook-up to something involving brightly-colored aliens on a screen.
