Brain scientist warns were heading for AI-fueled dementia crisis | Latest Tech News
We’ve been told that many issues increase our risk of dementia — genetics, an excessive amount of alcohol, not enough exercise, improper nutrition, high blood pressure, the dangers go on and on.
Neuroscientist Vivienne Ming needs to add one more merchandise to the record — artificial intelligence.
Scientists have already sounded the alarm that US dementia instances may almost double by 2060, thanks to our ageing population and rising charges of obesity, diabetes and hypertension.
Now, Ming is warning that AI may contribute to a “dementia crisis” as it weakens the mind systems accountable for curiosity, consideration, high-order reasoning and government operate, among other duties.

“My own data shows that students using AI in the most common way — asking it questions and accepting the answers — show more than a 40% reduction in the gamma-band brain activity that indicates active cognitive engagement,” Ming, writer of the new ebook, “Robot-Proof: When Machines Have all the Answers, Build Better People,” told The Post.
“Their brains are measurably less active than when they work without AI.”
Ming describes what an AI-powered dementia crisis may seem like — and shares 4 early warning indicators that recommend overreliance on AI.
How can AI have an effect on cognition?
A survey last yr revealed that 56% of US adults use AI instruments, with 28% utilizing them at least once a week.
Seeking data or fast solutions is one of the top features. For people who use AI this method, Ming said, adjustments to cognition aren’t immediately noticeable but construct over time.
“When the answer is always one tap away, we stop developing the habit of wondering,” she explained.
“Without errors to drive learning, our brain’s reward circuits stop responding to mystery. We short-circuit the parts where wondering becomes exploration.”

Metacognition is also affected. That’s the awareness and regulation of your own considering, also recognized as “thinking about thinking.”
Ming describes it as “testing your own understanding against reality, experiencing the gap and updating.”
When AI does that work for you, you get the phantasm of understanding slightly than true ability acquisition.
“We need ‘productive friction,’” Ming said, “the challenges that make life a little harder and thereby make us better.”
How sure are we that a crisis is on the horizon?
Many innovations over the years have modified the way in which we predict — calculators and smartphones are just a few — but no one blamed calculators for a dementia crisis.
GPS navigation is the closest analogy to AI, Ming said.
Habitual GPS use has been shown to diminish spatial reasoning by lowering exercise in the mind area accountable for forming mental maps — the hippocampus.
“While GPS offloads one cognitive function, AI is designed to offload any cognitive function you’re willing to give it: writing, reasoning, planning, synthesis, judgment,” Ming famous.
“The substitution is nearly total and it’s self-reinforcing, because AI that’s better than you at something creates a temptation to stop practicing that thing, which makes you worse at it, which makes you more dependent on the AI.”

Experts have long advisable seniors interact in stimulating work, read and be taught new expertise to strengthen their cognitive reserve, doubtlessly staving off dementia.
If there may be an AI-fueled dementia crisis, Ming said it “would look like a gradual, population-level compression of cognitive reserve, the brain’s accumulated resilience against age-related decline.”
She acknowledged that AI instruments haven’t been around long enough to measure long-term impression, “but the mechanistic evidence is there, the short-term behavioral evidence is there, and anyone claiming we need more proof before taking this seriously is applying a standard of certainty they don’t apply to anything else they care about.”
Can the mind positively adapt to AI use?
You need to use AI, but you also need to protect your cognitive reserve.
The best method could be to have the AI act as an “adversarial collaborator” that doesn’t blindly agree with your inputs, Ming steered.
The AI would problem your reasoning, establish weak evidence and pressure you to refine your arguments.
It doesn’t work if you “use AI the way most people currently use it — as a magic genie that provides answers,” Ming said.
Early warning indicators that can recommend AI dependence
- You battle to start a doc without AI producing a draft first.
- You can observe a complicated argument as you read it, but can’t reconstruct it an hour later.
- You can’t keep up with a long ebook without frequent summaries.
- You categorical confidence about expertise you may’t display if examined.
“These are the signs of a monitoring loop that has stopped running,” Ming said.
