Can you still reverse early-stage forgetfulness with your lifestyle?
Lifestyle can probably slow early-stage forgetfulness and sometimes partially improve it, but full reversal has not been demonstrated. The most support exists for a combination of exercise, healthy eating, and staying cognitively active.
Almost half of people with mild, measurable forgetfulness return to normal on their own. Two large studies in people, with 744 and 769 participants respectively, saw this happen in between a third and almost half of them. Those who stayed active in multiple areas of life were more likely to recover. But you cannot conclude from this that lifestyle is the only explanation.
The strongest evidence that lifestyle genuinely helps comes from a study of 1,260 people with an elevated risk of dementia. Those who spent two years eating more healthily, moving more, doing cognitive training, and keeping their blood pressure and cholesterol in check scored measurably better on memory and thinking tests than the group that did not. The difference was small but demonstrable. Seven percent of participants experienced muscle pain or other complaints from the intensive exercise.
Fully reversing the decline is not realistic, but slowing it down combined with a modest improvement is. Cognitive training and psychological support also help, though the effects are small. Exercise, healthy eating such as a Mediterranean diet (vegetables, fruit, olive oil, fish, little red meat), and mental activity together have the most support from the evidence. Individual supplements have shown mixed and partly disappointing results.
The evidence comes from one large controlled study of 1,260 people, a pooled analysis of 18 controlled studies, two long-term studies following 744 and 769 people respectively, and several review articles. One planned study of 105 people has not yet produced results.
Can you prevent dementia through your lifestyle?
Lifestyle does meaningfully influence your dementia risk: one third of all cases are linked to modifiable factors such as physical activity, blood pressure, and smoking. Especially if you already have an elevated risk, tackling several things at once is worthwhile.
Which lifestyle habits protect your brain health over the long term?
Cognitive activities, a plant-based dietary pattern, and regular exercise, preferably in combination, offer the best-supported protection for your brain over the long term. Hard cause-and-effect evidence is still lacking, but the associations are broad and consistent enough to take seriously.
What can I concretely do to prevent dementia?
Controlling blood pressure, quitting smoking, staying active, and addressing hearing loss are the steps with the strongest support. No single measure offers a guarantee, but paying attention to several of these factors at once gives you the best chance.
What are the causes of memory loss?
Memory loss has many possible causes that differ greatly from one another. If you suddenly develop memory problems, always have them assessed by a doctor so that a treatable cause is not missed.
How do you train your memory effectively?
Memory can be trained, but the smartest investment is regular exercise: that has the strongest and broadest support for cognition and memory. Targeted memory training helps, but less spectacularly than is often assumed.
Do brain-training games help prevent cognitive decline?
Brain-training games give healthy older adults at most a temporary and small boost on test scores, but that effect fades over time. People who enjoy them take little risk, but high expectations are not warranted.
