The pastimes with the strongest science behind them share one inconvenient trait, and it has nothing to do with apps.
Ask people past 60 about their memory, and a familiar story surfaces. They can recite their childhood phone number but not why they walked into the kitchen. A word stalls. A name arrives an hour late. The grocery list stays on the counter.
Those moments can feel like a verdict. Most of the time, they are not.
The brain at 60 can still build new connections and, in at least one region, grow new cells. Researchers keep landing on the same surprise: The activities with the strongest evidence are everyday hobbies, many older than the term brain training, and what unites them is that they are hard.
Skills That Refuse to Get Easy
1. Digital photography — A camera full of unfamiliar dials and a stack of awful first photos is exactly what the brain needs.
At the University of Texas at Dallas, Denise Park assigned 221 adults ages 60 to 90 to learn digital photography, learn quilting on computerized sewing machines, do both, or spend the same hours in a social club or on easy puzzles. The high-challenge groups put in about 16 hours a week for three months. Only those learning demanding new skills improved on tests of episodic memory, which tracks what happened and when. The social club, with just as much company, saw no change.
The camera holds no magic; any skill that stays hard for months would likely work.
2. Learning an instrument — Playing two-handed scales while reading notation and listening forces the brain to juggle several tasks at once.
Jennifer Bugos at the University of South Florida randomly assigned 155 adults ages 60 to 80 to group piano lessons, computerized brain training or no treatment for 16 weeks. The piano group pulled ahead on verbal fluency and executive function, the mental command center that decides what to keep and what to discard. The brain-training group did not.
Executive function sits upstream of memory, helping someone remember the prescription on the way home.
Steps, Squares and Sidewalks That Protect Memory
3. Dancing — Researchers in Magdeburg, Germany, split healthy seniors between a dance program with constantly changing routines and a standard fitness program of cycling and Nordic walking. After 18 months, both groups showed growth in the hippocampus, the region central to forming new memories and among the first to shrink with age. Only the dancers also improved their balance. The trial was small, but it echoes years of exercise research.
4. Crossword puzzles — Researchers at Columbia and Duke assigned older adults with mild cognitive impairment, average age 71, to 12 weeks of online crosswords or computerized cognitive games. At 78 weeks, the crossword group scored better on a standard cognitive measure and showed less brain shrinkage on MRI. With no do-nothing control group, the study shows only that crosswords beat the apps. The likely edge is retrieval, the act of searching for stored knowledge, which tends to weaken first.
5. Walking — Kirk Erickson, then at the University of Pittsburgh, placed 120 sedentary older adults in a yearlong walking or stretching-and-toning program. Walkers, building up to about 40 minutes three times a week, saw hippocampal volume rise 2 percent while the stretching group’s fell 1.4 percent, roughly reversing one to two years of age-related loss. Critics noted the stretchers’ memory improved too, muddying the link to recall. The structural gain, however, held.
Purpose, Pages and Staying Power
6. Tutoring children — In the Baltimore Experience Corps trial, older adults tutored elementary students 15 hours a week for two years. Men in the program saw brain volume increase 0.7 to 1.6 percent, including in the hippocampus, while men in the control group lost volume at the usual rate. Women trended similarly but did not reach statistical significance.
7. Reading and writing — Robert Wilson at Rush University Medical Center followed 294 older adults for about six years before their deaths, then examined their brains. Those with frequent late-life mental activity declined 32 percent more slowly, while infrequent participants declined 48 percent faster, even after accounting for plaques and tangles found at autopsy. The habit did not stop the damage, but it seemed to help people function despite it, though the link is correlational.
Why Difficulty Is the Secret Ingredient
Across all seven, the pattern is effort, not the activity itself. A mastered hobby stops asking anything of the brain. The good news is that difficulty costs nothing. No subscription, device or diagnosis is required, just something you are bad at and the patience to stay bad at it for a while.
