One Part of Your Brain Could Point to the Mind’s Decline
The Key to Mind's Decline? A Single Region of the Brain.
Brain Area Linked to Cognitive Decline
By Ernie Mundell HealthDay Reporter
Picture this: a tiny memory center in your brain shrinking away, signaling the decline of your mental faculties. Sounds like a scene straight out of a sci-fi movie, right? Well, according to a new study, it might not be far from the truth.
The star of this show is the hippocampus, a two-sided structure nestled deep within the brain’s temporal lobe, located roughly above each ear. If the brain were a cinema, the hippocampus would be its blockbuster – responsible for storing and transferring short- and long-term memories.
Published in the journal Neurology, the study examined brain scans from 128 people with an average age of 72. Dr. Bernard Hanseeuw and his team at Harvard Medical School in Boston used these scans to track changes in key brain proteins linked to Alzheimer’s disease – amyloid plaques and tau tangles. But that’s not all; they also measured the size of the participants’ hippocampus over a span of seven years.
And what did they uncover? Brace yourself: the participants with the most significant hippocampus shrinkage were also the ones with the most noticeable thinking declines. It’s as if the shrinking hippocampus pressed the fast-forward button on mental decline, independently of the levels of amyloid or tau proteins.

The researchers estimate that this shrinkage could account for up to 10% of thinking declines. Dr. Hanseeuw even goes as far as saying, “These results suggest that neurodegenerative diseases other than Alzheimer’s are contributing to this decline…” Now that’s a twist worthy of a thriller movie!
But fear not, dear readers, for Dr. Hanseeuw offers hope. He believes that by measuring the volume of the hippocampus, we could better evaluate the causes of cognitive decline that are currently difficult to measure. Think of it as using special detective tools to crack the case.
Not only that, but this could also help predict who would respond to new drugs aimed at combating cognitive decline. It’s like having a crystal ball that tells us if those magic potions will work their spell.
So, don’t fret if you misplace your keys or forget a friend’s name. Instead, let’s embark on a brain-saving journey together. But before we go, do check out the hippocampus exhibit at Johns Hopkins Medicine for some fantastic brain-themed fun. And if you’re up for a visual treat, dive into the slideshow on dementia and aging brains – it might just blow your mind!

Drumroll please! Ladies and gentlemen, thank you for joining me on this extraordinary brain adventure. Remember, our hippocampus might shrink, but our sense of humor should always remain intact. Stay sharp, stay curious, and hey, let’s not forget to exercise our brains daily – they’re a muscle too, you know!
