I'm a neurologist — don't ignore these 10 signs that may mean your brain is in trouble
Dementia — which gradually erodes memory, concentration and judgment — affects over 6 million Americans and accounts for more than 100,000 deaths annually.
Symptoms tend to be relatively mild at first and worsen over time. Though there's no cure for dementia, it's important to recognize the potential signs because early diagnosis can improve treatment outcomes.
Other life-threatening brain conditions, like stroke and a ruptured aneurysm, have symptoms that appear more abruptly.

It's important to pay attention to brain health because it significantly influences our ability to think, learn, communicate and make decisions.
'As a neurologist at MIND and the medical director of the stroke program at Henry Ford St John Hospital, I see patients all the time who brush off symptoms,' Dr. Joshua Nass, of the Michigan Institute for Neurological Disorders (MIND), told The Post.
'Many times, it is the families who notice first,' he added. 'Unfortunately, sometimes it is too late.'
Here are 10 neurological signs that Nass says shouldn't be dismissed.
Sudden, severe headache
'If you are not a headache person and this is the worst headache of your life, this could be a sign of an aneurysm or bleed, and this should be assessed emergently at the ER,' Nass said.
Some 6.7 million Americans — or 1 in 50 people — are believed to have an unruptured brain aneurysm.

High blood pressure can put stress on blood vessel walls, causing them to thin.
A bulge can develop in the weakened part of the wall. That's known as an aneurysm.
It can burst if the wall gets stretched too much.
Small, unruptured aneurysms typically don't cause noticeable symptoms, but larger ones can press on nerves or brain tissue, causing headaches, vision problems or other neurological issues.
Weakness or numbness on one side
'Call 911,' Nass said. 'Even if it goes away in a few minutes, this may represent a warning sign for a stroke.'
6 Strokes can lead to permanent brain damage, disability or even death.

A stroke occurs when blood flow to the brain is disrupted or severely reduced. Brain tissue is deprived of oxygen and nutrients, potentially causing damage or long-term disability.
Weakness or numbness can happen when blood flow to areas of the brain responsible for motor control is compromised.
Slurred speech or trouble speaking
This could also indicate a stroke that damaged areas controlling speech and language.
Abrupt vision changes
'Loss of vision or double vision could range from optic neuritis, stroke or a retinal problem,' Nass said.
6 Sudden vision changes may indicate a serious medical condition and require immediate attention.

Optic neuritis is inflammation of the optic nerve, which carries messages from the eyes to the brain so you can see.
Memory changes or confusion
Memory problems and confusion can stem from a range of issues, including metabolic imbalances, infections and dementia.
'With new technology, we can detect dementia earlier, and newer treatment options are available to help prevent or slow down decline,' Nass said.
Persistent dizziness or an off-balance sensation
Talk with a doctor if you experience relentless, room-spinning dizziness that leads to unsteadiness or falls.
6 Dizziness can come from issues in the inner ear or the brain.

'If persistent, this may represent more than an inner ear problem, and brain imaging may be warranted,' Nass advised.
Seizure-like activity
'These are not always full-body convulsions but may be staring spells or muscle jerks,' Nass shared.
'Especially if it's happening for the first time, a full workup to exclude a brain problem (including a tumor) should be completed.'
Loss of consciousness, like by fainting
'Although this typically may represent a cardiovascular issue, a brain etiology must be excluded,' Nass said.
6 Fainting is caused by a sudden reduction in blood flow to the brain.

Some neurological conditions — like a transient ischemic attack or 'mini-stroke' — can cause fainting or fainting-like symptoms.
Numbness and tingling in hands or feet
'More commonly, this may represent a neuropathy from vitamin deficiencies or diabetes, although alternative causes such as multiple sclerosis or other spinal cord pathology should be excluded,' Nass said.
Tremors/uncontrollable movements
'Many times we see tremor in the office and it is a benign essential tremor, which can run in families,' Nass said, 'but Parkinson's should be excluded, including other movement disorders.'
Parkinson's disease patients — there are about a million in the US — tend to experience slow movement, tremors, stiffness and difficulty walking.

Medicaid changes will hurt family caregivers, experts warn
Medicaid cuts under President Trump's sweeping tax and spending package will harm family caregivers, experts warn, by reducing access to health care for themselves and the people they care for, which could then lead to more caregiving responsibilities. The Congressional Budget Office estimates the package will reduce Medicaid spending by roughly $911 billion over the next 10 years and increase the number of uninsured Americans by up to 10 million. Some of those who could lose coverage are among the 8 million — or 13 percent — of family caregivers in the United States who receive their health insurance coverage through Medicaid, according to the National Alliance of Caregiving. 'We are very concerned of the impact of the just finalized Medicaid cuts on the community of family caregivers,' Jason Resendez, president and CEO of the alliance, said during a call with reporters earlier this week. Medicaid recipients will be subject to more frequent eligibility checks, in part, due to revised work requirements for the joint state and federal program. Now, adults between the ages of 19 and 64 will need to work or participate in community service activities for at least 80 hours a month to be eligible for health care coverage under Medicaid. There are some exceptions for parents with dependents as well as for those deemed 'medically frail' or who are pregnant or postpartum, according to the health care policy nonprofit KFF. Many caregivers cannot work outside the home because of the intense care their family members need, or can only work limited hours, which can make fulfilling Medicaid work requirements difficult to impossible. This was the case for Lisa Tschudi, host of caregiving podcast 'Love Doesn't Pay the Bills,' who stayed home full time to take care of her daughter who has ataxic cerebral palsy and epilepsy. 'We really did not have other options,' she said. 'I, many times, tried to line up some non-me care for her during the workday and a job for myself, and I never really got my start in a paid job in that way.' Her daughter's epilepsy was poorly controlled for years as a child and teen, which required her to travel for frequent doctors' appointments on top of taking care of her younger daughter. 'It was a lot to manage,' she said. Work requirements might force some family caregivers to look for outside help, if that is an option, which represents a new expense and, potentially, a new challenge to navigate. 'Even if you can find outside providers to come in … families often find that they are not reliable,' said Elizabeth Edwards, senior attorney at the National Health Law Program. 'Some of that inconsistency of how people show up as providers can mean it's very hard to hold a job.' Family caregivers also already spend huge amounts of time navigating numerous bureaucratic hurdles, and new work requirements will add to the paperwork they have to fill out to prove they are eligible for health care under Medicaid. This extra administrative work also increases the likelihood of errors occurring in the eligibility system, which could delay coverage or prevent some from being enrolled altogether, according to Edwards. That is what happened to many Medicaid recipients in Arkansas and Georgia when the two states implemented work requirements in 2018 and 2023, respectively. More than 18,000 people in Arkansas lost Medicaid coverage over the 10-month period the state rolled out work requirements without increasing employment, according to a KFF analysis. Georgia still has one of the highest uninsured rates in the country at 12 percent, according to the Commonwealth Fund. 'We anticipate [them] not just being faced with these eligibility issues, but family caregivers losing Medicaid coverage because of these additional hurdles that they'll be forced to traverse,' Resendez said. About 11 million family caregivers in the U.S. receive payment for the care they provide, according to Resendez. Those payments primarily come through home and community-based services and consumer-directed programs at the state level. But those programs will likely start to lose funding as states are forced to decide what to fund with fewer Medicaid dollars, experts told The Hill. 'When states have less money and are forced to make decisions, home and community-based services are the first optional benefits to get cut,' Resendez said. Tschudi, as well as her husband and second daughter, are all paid family caregivers under a home and community-based service their home state of Oregon's Medicaid program provides. Without that program, her family would likely have to go back to unpaid caregiving, which would not be financially possible at this time. 'I don't wish it on anyone,' Tschudi said about the struggles that come with unpaid caregiving. 'I really think you leave families in an impossible situation when you don't pay for caregiving.'

Coke with cane sugar may not be that big of a MAHA victory
Coca-Cola is going to offer a cane sugar version of its signature beverage, rather than one sweetened with corn syrup. Major segments of the food industry, including General Mills and Heinz, have pledged to remove certain colored dyes from their products. The fast-food chain Steak 'n Shake is making french fries in beef tallow rather than vegetable oil. Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. has claimed them all as significant victories for his 'make America healthy again' (MAHA) movement as part of its quest to reform the U.S. food supply. 'Froot Loops is finally following its nose — toward common sense,' Kennedy said on social platform X after cereal-maker WK Kellogg Co. agreed to remove synthetic dyes from its cereal by 2027. 'I urge more companies to step up and join the movement to Make America Healthy Again.' But nutrition and food policy experts say the moves are a far cry from actually making America healthier. While they praised the administration and MAHA for drawing attention to what they said is a broken food system, the victories touted thus far have been largely symbolic and rely on the goodwill of an industry that is eager to appear helpful to avoid strict government regulation. 'I think if we're really curious about improving public health, some of the small health initiatives, like … replacing high fructose corn syrup with cane sugar, are really not where the administration should be channeling their efforts and leveraging the power that they do have,' said Priya Fielding-Singh, director of policy and programs at the George Washington University Global Food Institute. 'I think they should be focusing their efforts on initiatives that actually address the root of the problem, which is essentially a food system that promotes excess sugar, salt and fat,' Fielding-Singh said. Health officials and GOP lawmakers have taken to conservative media in recent weeks to tout the commitments from food and beverage companies to remove synthetic dyes. According to the HHS, nearly 35 percent of the industry has made such a commitment. But there's been no force behind the companies' actions, which experts said is an issue. 'Simply switching from synthetic to natural colors will not make these products less likely to cause obesity,' said Jerold Mande, a former senior official during three administrations at the Food and Drug Administration (FDA), the Department of Agriculture and the Occupational Safety and Health Administration. Barry Popkin, a nutrition professor at the University of North Carolina Gillings School of Global Public Health, said Kennedy could make a major statement by banning all colors and dyes. It wouldn't directly make Americans healthy, but it would go a long way toward making ultra-processed food look less appealing. 'All this voluntary stuff only goes so far. It really does minimal impact,' Popkin said. 'Unless he goes to the FDA and has the FDA change a regulation … there's nothing.' Kennedy has also singled out the use of high-fructose corn syrup as a major contributor to diabetes and obesity. He has previously called it 'poison,' an epithet he repeated in late April when talking about sugar. When Steak 'n Shake said earlier this month it was going to sell Coca-Cola with real cane sugar, Kennedy praised the move. 'MAHA is winning,' Kennedy posted on X. But experts said there's no substantial difference in the benefits of using cane sugar as a substitute for high-fructose corn syrup. 'At the end of the day, a Coke is still a can of Coke. It's not a fruit or a vegetable, right? And so if you're not shifting consumption away from these higher calorie, lower nutrient processed foods, toward nutrient dense, health promoting foods, then you're not actually going to be shifting the health of Americans in the right direction,' Fielding-Singh said. But if Kennedy thinks sugar is poison, 'they're both sugar and would both be poison, in his words,' said Mande, who is now CEO of Nourish Science. Health officials argue industry cooperation is key to the MAHA agenda. 'Working with industry is the best place to start. And we believe in industry to do the right thing when called upon,' Food and Drug Administration Commissioner Marty Makary and Centers for Medicare and Medicaid Services Administrator Mehmet Oz wrote in a joint op-ed in The Wall Street Journal. 'Our agencies are in a strong position to show Americans which companies are doing the right thing when it comes to popular reforms. By the time we're done, we will have built new relationships and be better positioned to hold them accountable,' Makary and Oz wrote. Yet there is plenty the agency can, and should do, that industry has pushed back against. Aviva Musicus, science director of the nonprofit Center for Science in the Public Interest, said MAHA is wasting its political capital. 'It's striking that we haven't seen the administration use policy to improve the food system. It's solely relying on voluntary industry commitments that we've seen repeatedly fail in the past,' Musicus said. 'In pushing the food industry to change, Trump and RFK Jr. have a chance to live up to their promises to fight chronic disease. Coca-Cola is at the table, but they're wasting the opportunity to actually improve health. The administration should focus on less sugar, not different sugar,' Musicus added. Popkin said he would like to see warning labels on ultra-processed foods high in sodium, added sugar and saturated fat. Kennedy 'hasn't tackled ultra-processed food yet. That'll be where he could make an impact on health in the U.S. and all the non-communicable diseases, including obesity. But he hasn't gone there yet,' Popkin said. The coming months will reveal more on the MAHA movement's plans to change how Americans eat. New dietary guidelines will be released 'in the next several months,' Kennedy said recently. In addition, a second MAHA report focused on policy recommendations is expected in August. 'We have to be considering that there could be real potential down the road,' Popkin said. 'But [there's been] nothing yet. That document will tell us if there ever be.'
