Study Shows an Increasing Trend of Brain Fog Among Adults

 Analysis of over 4.5 million U.S. survey responses spanning a decade (2013–2023) shows a rise from 5.3% to 7.4% in reported cognitive disability nationwide, with an exceptional surge in the 18–39 age group and a clear influence of income and education.

A new study indicates that self-reported problems with memory, concentration, and decision-making are occurring with increasing frequency, particularly among young adults in the United States, with socioeconomic factors playing a central role in the phenomenon. The findings were published in Neurology, the journal of the American Academy of Neurology. 

"Difficulties in memory and thinking have become one of the most commonly reported health issues among adults in the U.S.," says study author Adam de Havenon, M.D., M.S., from the Yale School of Medicine in New Haven, Connecticut, and a Fellow of the American Academy of Neurology. "Our research shows that the phenomenon is expanding, especially among younger adults, and that social and structural factors likely play a key role."

A Decade of Data from the BRFSS 

 To reach their conclusions, the researchers analyzed more than 4.5 million responses to annual surveys collected through the CDC’s Behavioral Risk Factor Surveillance System (BRFSS) between 2013 and 2023. Respondents were asked the key question: "Due to a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions?" Those who answered "Yes" were classified as having a cognitive disability.

The analysis specifically excluded data from people who reported depression, and the year 2020 was omitted to account for the unique stresses of the early COVID-19 pandemic. The data showed that the significant uptick in self-reported cognitive issues began around 2016. 

During the decade, the overall prevalence of self-reported cognitive disability in the US rose from 5.3% in 2013 to 7.4% in 2023. 

The sharpest jump, however, occurred among young adults: 

* In the under-40 age group (18–39), the rate nearly doubled—from 5.1% in 2013 to 9.7% in 2023. This age group was the primary driver of the overall national rise. 

* In contrast, a slight decrease was recorded among older adults: in the 70-and-over age group, prevalence dropped from 7.3% to 6.6%.

Structural Disparities Highlighted 

 Although this study relies on self-reported data rather than a clinical diagnosis, the research reveals profound socioeconomic disparities in the trend. 

The researchers found that adults with a household income of less than $35,000 per year consistently reported the highest rates, which increased from 8.8% to 12.6% over the study period. For comparison, among those with an income greater than $75,000, the rates rose only from 1.8% to 3.9%. 

Patterns by Race and Ethnicity
Despite White individuals constituting the majority of respondents, the increase in cognitive disability was recorded across nearly all racial and ethnic groups: 

American Indian/Alaska Native: 7.5% - 11.2% (Highest Prevalence) 

Hispanic 6.8% - 9.9% 

Black 7.3% 8.2% 

White 4.5% 6.3% 

Asian 3.9% 4.8% (Lowest Prevalence) 

"The findings indicate that the steepest increases are occurring among people who are already facing structural disadvantages," Dr. de Havenon states. "We need to better understand and address the underlying socio-economic factors that may be driving this trend."

What is Driving the Surge?  

More research is needed to pinpoint the exact cause behind this significant surge among younger adults, given the potential long-term consequences for health, workforce productivity, and healthcare systems. 

Study co-author Ka-Ho Wong, a population health scientist at the University of Utah, has suggested that one factor could be the increased mental burden stemming from changing economic conditions. "Economic stressors, like job market uncertainty and changes in work environments, could be a huge factor," Wong noted in related discussions about the findings.

Dr. de Havenon adds that the increase could reflect an actual change in brain health, greater public awareness and willingness to report these issues, or other health and social factors. "Either way," he concludes, "the rise is real, and it is especially pronounced in the under-40 age group." 

 The study acknowledges its limitations, including the reliance on telephone surveys—which can be subject to respondents' memory inaccuracies—and a broad, self-reported definition of "disability."

This Doctor Says Humans Actually Need 7 Kinds of Rest (and You're Probably Not Getting All of Them)Getting a solid eight hours of sleep isn't enough.

We're only a week into 2021 and we've already had a coup attempt, a rampaging new strain of Covid, a halting vaccine rollout, and even attack squirrels (murder hornets and meth alligators are so 2020). It does not appear we're in for a restful year. But even if the world makes it hard to relax, at least one doctor insists we all need to find a way to reset and recharge anyway. 

And that's more complicated than just switching off your brain and switching on Netflix every once in a while. 

In a new TED Ideas post, Saundra Dalton-Smith insists "we go through life thinking we've rested because we have gotten enough sleep -- but in reality we are missing out on the other types of rest we desperately need" and outlines the seven types of rest that are essential for human flourishing. 

1. Physical rest

This is the usual definition of rest we're all familiar with. But while we know we need to spend a decent number of hours in bed to stay healthy, a steady drumbeat of studies shows a large proportion of us still don't get enough physical rest. 

2. Mental rest 

Always have a tornado of thoughts swirling in your head from the moment you wake up to the moment you (finally) fall asleep? You need more mental rest, and even if you sleep a solid eight hours a night, you're not going to feel fully recharged until you get it. 

"The good news is you don't have to quit your job or go on vacation to fix this. Schedule short breaks to occur every two hours throughout your workday; these breaks can remind you to slow down. You might also keep a notepad by the bed to jot down any nagging thoughts that would keep you awake," suggests Dalton-Smith. 

3. Sensory rest

Staring at screens all day and all night means your eyes never get a proper rest, but this isn't the only reason many of us never give our senses a break. Noisy cities, pinging notifications, and blaring music all contribute to constant sensory stimulation. Your brain needs a rest now and again. Consciously close your eyes and give yourself the gift of silence for short periods throughout the day. 

4. Creative rest 

Inc.com and other sites are full of tips on how to be more creative, but just as important as striving to put out new ideas is remembering to pause and take in the building blocks out of which they're constructed -- awe, art, inspiring people, and time to let it all marinate. 

5. Emotional rest 

This "means having the time and space to freely express your feelings and cut back on people pleasing," Dalton-Smith explains. "Emotional rest also requires the courage to be authentic. An emotionally rested person can answer the question 'How are you today?' with a truthful 'I'm not okay' -- and then go on to share some hard things that otherwise go unsaid."

In other words, we all need the space to stop pretending for ourselves and others and get real about our feelings sometimes. 

6. Social rest 

Some people energize you. Others drain you (here's how to spot them). If you spend too much time with the latter type, you're going to need some emotional rest. 

7. Spiritual rest 

All humans, no matter their religious affiliation or lack thereof, have a need to feel connected to something larger than themselves. That's sometimes not easy to maintain in the middle of the minutiae of everyday life. The good news is science shows simple interventions can give you a quick dose of awe that should lead to measurable increases in well-being. 

So next time you think to yourself, "I'm tired," don't leave your complaint at that. Instead, dig a little deeper and try to identify just what sort of rest you're lacking exactly. Once you know what you're missing, you'll be in a much better place to figure out how to recharge effectively.

Important Things to Know About Stress-Related Sleep Issues

The hustle and bustle of daily life isn’t particularly conducive to healthy sleep habits, with both acute and chronic insomnia becoming so common it’s been time and time referred to as ‘an epidemic’. For some, the inability to have a good night’s sleep is a long-standing issue that requires constant medications and serious life limitations. And while each case of insomnia is unique, scientists have been finding more and more proof about the tightly knit connection between stress and sleeplessness. Find out more about this link and effective ways to combat stress-related insomnia in this article. 

The Symptoms and Causes of Insomnia

It has been estimated that as much as a third to half of the world’s population has trouble falling asleep at night, with the vast majority of people having experienced symptoms of insomnia at least once throughout their life. The condition doesn’t discriminate in terms of age or gender, although seniors and women are more likely to suffer from insomnia than children and men.

Many people confuse insomnia with a bad night’s sleep, but the symptoms of insomnia, unlike a bad night's sleep, last for days and sometimes months, and include:

    Difficulty falling asleep
    Waking up early or in the middle of the night
    Not feeling rested in the morning
    Feeling tired or sleepy throughout the day
    Attention and memory problems
    Being irritable, anxious or depressed

The causes of insomnia vary from person to person, with physical and psychological conditions, such as chronic pain and medications, and even certain habits, such as eating too much in the evenings contributing to the issue.


How Do You Know if Your Insomnia is Caused by Stress?
One of the most widespread causes of insomnia is stress, with major studies from Japan, South Korea, Sweden and the United States confirming the relationship. Scientists believe that the reason why stress causes insomnia is due to the excitatory effect it has on the nervous system.

Stress activates the neural pathways we associate with the fight or flight response, thus keeping us in a state of perpetual worry and tension. You will know that your sleeping problems are stress-related if they started during a period of increased stress or seem to get worse when you’re experiencing difficulties at work, with your personal life, or any other area of your life.

As you might expect, stress-induced insomnia itself is bound to make the sufferer’s life even more stressful, creating a vicious cycle of stress and chronic sleep problems. In the following section, we’ll discuss the simple, yet effective ways one can combat stress-induced insomnia.

How to Get Rid of Stress-Related Insomnia

According to scientists and sleep experts, minor but mindful lifestyle changes can really make a difference in improving one’s stress-related sleep issues without having to resort to medications. These minor tweaks and aids will work to help reduce your stress levels and prevent further exacerbation of insomnia the natural way.

1. Relaxation techniques, such as meditation and mindful breathing have been proven to be useful to lower stress levels are a useful tool for managing stress and hyperarousal that hinder sleep by letting you focus on something else other than your own thoughts. On a physical level, meditation was shown to increase the levels of the sleep hormone melatonin, reduce the heart rate and blood pressure, and activate the brain areas that are responsible for controlling sleep.

The benefit of this technique is that you can use it throughout the day, and not only at bedtime. Meditation apps and online guides are abundant and widely available, but they do require a bit of a commitment.

2. Spending time outdoors, exercising and staying active can likewise both reduce stress and will relax your muscles, train your heart and lungs, making it easier to get quality sleep. The downside of this approach is that not everyone can exercise due to medical reasons, and some of us simply don’t have the time.

3. Good sleep hygiene is likewise important, as it is capable of normalizing your circadian rhythms. In order to have a good night’s sleep, avoiding heavy meals and coffee in the evenings, have a consistent sleep schedule, dim the lights in your bedroom and limit the use of smartphones and laptops in the bedroom.

4. Listening to White Noise can help disrupt the surrounding noises and your racing thoughts to help you fall asleep. The noise can range from an indistinct noise to sounds of waves, water, and otsimplyher pleasant sounds, and can come in either specialized machines, or music you can play from apps and websites.

Research shows that white noise helps mask environmental sounds and makes falling (and staying) asleep easier. This is especially true about people who live or have to frequently sleep in noisy environments, such as big cities, or while traveling.

The New Tech Solution of Insomnia

This device combines the powerful effects of relaxation techniques with the ability to distract you from stressful thoughts and outside noises. It's called a Hoom Band, and it might become the easy solution for you if you experience trouble sleeping.

This device is a lightweight, comfortable, and washable headband with a special light, the flickering of which is suggested to help with the normalization of circadian rhythms, and a set of sleek headphones that won't disrupt your sleep (an image of the device can be seen above). It comes with a free app downloadable on your smartphone, which contains stories, guided meditations, and calming sounds, all carefully curated by sleep experts.

When you're in bed and ready to fall asleep, put the band on, select one of the stories, and let the sound distract you from the noisy world and busy mind while the stress-disrupting light slowly lulls you to sleep. The calming effect is almost instant, you will feel your body relax and mind focus on the journey you're listening to instead of stressed out inner voice that doesn't let you fall asleep at night.
