Puzzling and Brain Health Update: Crosswords and Jigsaw Puzzles

[Loads of images come up when you google “brain health” or “brain fitness,”
but I liked this one much more than all of the ones with brains lifting barbells.]

“Brain health.” “Brain fitness.” “Brain-training.” Ever since I started writing for PuzzleNation Blog, I’ve been chronicling the debate over whether solving puzzles makes a verifiable, detectable impact on brain function, development, and overall health.

There are plenty of puzzle magazines, apps, websites, and services that claim to help with brain fitness. Some make vague assertions related to memory, mental flexibility, and other cognitive functions. Others are insanely specific, promising to reverse the aging process or to help prevent the onset of dementia and other cognitive difficulties later in life.

(Examples of the latter style of advertisement are rarer these days after Lumosity’s two-million-dollar payout for falsely advertising that their puzzle games could “reduce or delay cognitive impairment associated with age and other serious health conditions,” as well as “stave off memory loss, dementia, and even Alzheimer’s disease.”)

Whether we’re talking short-term or long-term benefits to brain health from puzzling, you’ll find dozens of articles online arguing both sides. Unfortunately, so much of the data out there is inconclusive, or is hindered by test groups too small to be applicable to the general population.

However, the positive, verifiable data we can find is encouraging.

Tetris has been used by researchers to help people suffering from traumatic flashbacks, a type of post-traumatic stress. The University of Exeter conducted a study involving more than 19,000 participants that concluded that adults age 50 and older who regularly solve puzzles like crosswords and Sudoku have better brain function than those who do not.

(While 19,000 is still relatively small when compared to millions upon millions of adults over 50, it’s still one of the largest test groups yet assembled for brain health studies related to puzzles.)

And while people are always discussing short-term memory or long-term memory and how they relate to puzzle solving, it turns out there’s a middle ground between the two that crosswords may have a positive effect on. An article from Scientific American last year discussed how crossword solving engages the episodic buffer, one of the mechanisms related to our working memory, our ability to temporarily hold information while performing cognitive tasks.

Most cognitive activities engage the working memory through either verbal components or visuospatial components. (Visuospatial means how we perceive the relationships between different objects in multiple dimensions). But as it turns out, while playing Scrabble or solving crosswords, both visuospatial and verbal components are utilized by the short-term memory.

Of course, this is preliminary work, and there’s so much more to learn about short-term and long-term memory, but apparently, wordplay like Scrabble and crosswords could have a unique effect on how our working memory functions. That’s pretty cool!

But they’re not the only puzzles that we’ve discovered some fascinating new details about. Jigsaw puzzles can have a positive effect on the brain during the solving process.

Now, like crosswords and Sudoku puzzles, jigsaw puzzles have been the subject of several articles claiming they can help with brain health (or even decrease the presence of Beta-amyloid protein in the brain, a major component of the plaque that indicates Alzheimer’s disease). But I cannot verify those facts in scientific journals to my satisfaction, so I’m tabling that part of the argument.

What I do want to talk about it is how jigsaw puzzle solving can induce a mental state similar to dreaming, one that helps with stress, relaxation, and mood.

The company Sanesco Health is heralded as an industry leader in neurotransmitter testing, and according to an article on their site, placing those tricky little pieces in the right places can do you a world of good:

The connections made while working on jigsaw puzzles aren’t limited to our brain cells. Exercising both sides of the brain simultaneously also allows the brain to move from a Beta state, the wakeful mind, into an “Alpha” state, the same mental state experienced while dreaming. The Alpha state is where we tap into our subconscious mind.

Jigsaw puzzles naturally induce this state of creative, focused meditation, where connections can be made on deeper levels. And that release of dopamine with every puzzle piece you successfully place is an added bonus! Dopamine causes improved motor skills, an increase in concentration, optimism, confidence, and an enhanced recollection.

[Imagine how restful she felt after this!]

Considering that jigsaw puzzle sales spiked during the pandemic — with some outlets reporting sales increases of up to 500% — it sounds like people were either consciously or subconsciously making the perfect choice to cope with the stresses of lockdown.

As always, we’ll keep our eye out for any additional data on these findings.

But in the meantime, happy puzzling! It might be good for you!
