Keeping Sharp

Forgetfulness can be frustrating — but is it something we can fix? The short answer: while most age-related memory loss isn’t fully reversible, there are ways to slow it down, and in some cases, even improve it.

Some causes of memory issues — like stress, sleep deprivation, depression, vitamin B12 deficiency, or medication side effects — are treatable. In these cases, memory can bounce back with the right intervention.¹ That’s why it’s always worth talking to a doctor if forgetfulness becomes noticeable or persistent.

When it comes to conditions like Alzheimer’s disease, memory loss is progressive and not reversible. However, studies show that early intervention and lifestyle changes can slow the decline. In particular, physical exercise, mental stimulation, a brain-healthy diet, and managing medical conditions like high blood pressure or diabetes can protect cognitive function.²

One groundbreaking study — the Finnish FINGER trial — found that combining diet, exercise, cognitive training, and social activity helped slow memory decline in older adults at risk of dementia.³ This means that even after age 50, your daily habits can make a real difference.

In short, while not all memory loss can be reversed, it can often be slowed. The earlier you act, the more benefit you’re likely to see.
