They Aren't Forget-Me-Nots

Yesterday I couldn't remember the name of this flower that's been blooming in our yard for over 20 years. Refusing to do an internet search, I wanted to see when the name would come back to me. This morning, after six hours of sleep, the answer came instantaneously: nasturtiums.

Such lapses now come about once a month--well within "normal" and not necessarily a sign of impending dementia--yet I have come to realize that I could have taken better care of my brain when I was middle-aged:

More scientists are looking for clues in the midlife brain because efforts to target dementia in older people have largely failed, says Ahmad Hariri, a professor of psychology and neuroscience also at Duke...

Parts of the brain start to change faster during middle age, especially the hippocampus, which is important for remembering everyday events, says Sebastian Dohm-Hansen, a doctoral student at University College Cork in Ireland and first author of a March review study on brain aging published in the journal Trends in Neurosciences.

In your 40s and 50s, the white matter in your brain—the connections between brain areas—decreases in volume, says Dohm-Hansen. That likely results in slower processing speed, which could have further effects on cognition, he says.

In addition, proteins can build up in your blood, resulting in low-grade inflammation that can affect the hippocampus’s ability to encode and store new information, he says.

People keep their verbal language-based skills their whole life, says Moffitt. But the speed at which you process information and your capacity to solve new problems of logic and reasoning gradually diminishes with age...

There are no guaranteed ways to prevent dementia. But steps that help both your brain and your heart include exercising regularly, eating a healthy diet, and not smoking, as well as trying to avoid getting or managing conditions such as diabetes, high blood pressure and cholesterol, and obesity, and treating obstructive sleep apnea...

Also important is staying socially and mentally active and engaged, [Mayo Clinic Dr. David] Knopman says. “There are benefits of working in a challenging environment—it stimulates the brain—and it seems to be associated with better outcomes,” he says.

It's too late for me but maybe not for you, dear reader. Save yourself!
