Want to be the smartest one in the room? 3 common things that even neurologists avoid for 'healthy brain and sharp memory'
The human brain is a marvel, mysterious, powerful, and at the same time, delicate. Every single thought, memory, and idea springs from this 1.3kg organ. But keeping it sharp doesn't always mean doing more.

Sometimes, the smartest move is knowing what not to do.
Dr Baibing Chen, a professor of neurology at the University of Michigan, has seen it all, from memory lapses to full-blown cognitive decline. But when it comes to his own brain health, he shared a few secrets with 'CNBC Make It' that people need to know about. Even small shifts in daily life can have lasting effects on memory, focus, and brain resilience.
Here's all we need to know about what this top neurologist avoids, and what can actually be done instead to boost brain power naturally.
Overdependence on GPS
Dr Chen avoids using GPS too often. Why? A landmark study on London taxi drivers showed that their brains, especially the hippocampus, which is crucial for memory—were larger and more active than usual. Constant navigation without help was building their brain like a muscle.
A similar pattern was noticed in professions like ambulance driving, where spatial awareness is constantly used. These individuals had significantly lower Alzheimer's risk.
When the brain doesn't need to remember routes or use visual memory, those neural pathways begin to weaken. It's like skipping leg day at the gym—eventually, those muscles fade.
Try mentally mapping out short routes, recalling landmarks, or even drawing directions from memory. It's a small habit that can keep the brain agile and alert.
Energy drinks
Dr Chen warns against these sugar-packed, caffeine-laden drinks. While the instant jolt may feel like productivity, research reveals that excessive consumption may trigger sleep disorders, anxiety, and even seizures in extreme cases.

Some energy drinks contain taurine and B vitamins in amounts that aren't always regulated. These chemicals may interfere with natural brain function, disrupting sleep cycles and causing mental fog in the long run.
A quick walk in the sun, a tall glass of lemon water, or even breathing exercises can refresh the brain more sustainably. Natural energy lasts longer—and doesn't come with a neurological price tag.
Too many over-the-counter medications
Dr Chen has seen cases where frequent use of certain common medicines—like Pepto-Bismol—led to bismuth toxicity, mimicking symptoms of dementia.
Zinc overdoses from misguided wellness trends even caused irreversible damage to the spinal cord in some patients.
The issue isn't the medicine itself—it's the misuse. Even something as basic as cold remedies, when overused, can interfere with cognitive performance, especially in older individuals.
When symptoms are mild, consider rest, hydration, or doctor-approved home remedies first. And always stick to prescribed dosages—not influencer advice.
Reclaiming brain health
Boosting brain power doesn't always need biohacks or expensive supplements. Neurologists often suggest simple, grounding habits like:
Reading something new daily, even for 15 minutes—especially non-fiction or puzzles. Learning unfamiliar routes or languages, which activate underused brain areas. Taking mindful pauses in the day to reflect, breathe, and observe surroundings. These practices help stimulate neuroplasticity—the brain's ability to form new connections. And that's where real cognitive strength lies.

Alzheimer's disease: A blood test can detect early symptoms, finds study
Imagine getting tested for Alzheimer's with just a simple blood draw instead of going through complicated brain scans or spinal taps. Sounds like the future, right? Well, it's pretty much here. Researchers at the Mayo Clinic in the U.S. have been working on a new blood test that can accurately detect early signs of Alzheimer's disease, and the results are seriously impressive. This test looks at two specific proteins in your blood—amyloid beta 42/40 and p-tau217—both of which are linked to that gunky buildup in the brain called amyloid plaques, a telltale sign of Alzheimer's. So how accurate is it? Try 95% sensitivity, meaning it correctly identifies people who do have memory problems 95% of the time. That's pretty hard to beat. It also has 82% specificity, which means it's also really good at ruling out people who don't have Alzheimer's. What's even better? This isn't just lab testing. The study was done on over 500 real patients in a memory clinic—so it's based on actual, day-to-day medical situations, not just controlled experiments. Dr. Gregg Day, who led the study (published in Alzheimer's & Dementia journal), said this new blood test works just as well as the more invasive and expensive options we currently use. "It's about as accurate as spinal fluid testing," he told The Guardian, 'but way easier, less painful, and much cheaper.' In people who had Alzheimer's, the levels of p-tau217 were clearly higher compared to those who didn't, which helped the team confirm the diagnosis confidently. The best part? This blood test has already gotten the green light from the U.S. FDA—so it's not just theory anymore, it's actually available. 6 million Americans are living with Alzheimer's disease Alzheimer's disease is becoming a huge concern across the U.S.—and it's not just about forgetfulness in old age. It's a progressive brain disorder that slowly chips away at memory, thinking skills, and the ability to do everyday tasks. Right now, more than 6 million Americans are living with Alzheimer's, and that number is expected to nearly double by 2050. Most people with Alzheimer's are 65 or older, but it can also hit younger adults in what's called early-onset Alzheimer's. The biggest risk factor is age, but family history and genetics also play a role. The disease usually starts slow—maybe forgetting names or getting lost in familiar places—and worsens over time. The best part is science is catching up. New blood tests and brain imaging tools are helping doctors catch the disease earlier than ever before. There are also a few new medications out that might slow down the progression if taken early enough. Next up, researchers want to test it on even more diverse groups of people and also those who might be in the very early stages of Alzheimer's but don't have any symptoms yet. In short: diagnosing Alzheimer's just got a whole lot simpler—and that could change everything when it comes to early intervention and treatment.

Alzheimer's gene therapy shows promise to prevent brain damage
New Delhi: A novel gene therapy for Alzheimer's disease, which showed promise to protect the brain from damage and preserve cognitive function, has renewed hope for millions of patients with the neurodegenerative disease. Worldwide, approximately 57 million people live with dementia, and Alzheimer's disease is the most common cause, accounting for 60-70 per cent of cases. Alzheimer's occurs when abnormal proteins build up in the brain, leading to the death of brain cells and declines in cognitive function and memory. While current treatments can manage symptoms of Alzheimer's, the new gene therapy aims to halt or even reverse disease progression, said researchers from the University of California San Diego School of Medicine. They noted that, unlike existing treatments for Alzheimer's that target unhealthy protein deposits in the brain, the new approach could help address the root cause of Alzheimer's disease by influencing the behaviour of brain cells themselves. The study investigated the effect of hippocampal SynCav1 delivery in two distinct preclinical mice models. The results, published in the journal Signal Transduction and Targeted Therapy, showed that delivering the treatment at the symptomatic stage of the disease preserved hippocampal-dependent memory -- a critical aspect of cognitive function that is often impaired in Alzheimer's patients. Further, the finding stated that compared to healthy mice of the same age, the treated mice also had a similar pattern of gene expression. This suggests that the treatment has the potential to alter the behaviour of diseased cells to restore them to a healthier state. 'While multiple newly FDA-approved treatments focus on targeting amyloid-beta clearance in Alzheimer's patients, the therapeutic value of SynCav1 lies in its ability to protect vulnerable neurons and augment cellular responses -- mechanisms that differ from currently approved therapies,' said the researchers in the paper. Due to the multitude of neurotoxicity in the Alzheimer's brain, the team called for further studies to investigate SynCav1's therapeutic role when combined with amyloid-targeted drugs to enhance clinical outcomes.
