Brain Fog Causes, Symptoms, and Treatments
“I feel I’m just getting by on autopilot. I feel delayed with my actions and reactions to questions and situations.”
“It’s almost identical to what I go through when I’m awakened from a dream–just total bewilderment and almost complete inability to process anything that’s going on.”
“Sometimes I am very far off. I’ll pause and get confused in the middle of doing things. I’m drowsy all the time and just don’t know what’s going on.”
“I feel heavy on the front of my head, unrefreshed, similar to a hangover or jet lag.”
“I feel like Dory in Finding Nemo.”
If any of these sound familiar, then you know what “brain fog” feels like. Brain fog is a symptom—not a diagnosis or disease. It leaves a person temporarily unable to concentrate or think clearly.
Not all brain fog is created equally: anything from stress to dehydration to a urinary tract infection (UTI) can cause mild, temporary brain fog. COVID-19 itself may be increasing rates of a particular kind of brain fog seen in “long-haul” COVID cases.
Regardless of the cause, the forecast for the brain remains the same: foggy, forgetful, and fuzzy around the edges.
Fortunately, new treatments, such as the innovative hyperbaric oxygen therapy (HBOT) medical protocol at Aviv Clinics, may offer relief from brain fog. Understanding brain fog causes, symptoms, and tips to manage brain fog can help you take charge of this difficult cognitive condition.
What Is Brain Fog?
Brain fog describes a feeling of confusion and forgetfulness, as well as a lack of mental focus. The effects of brain fog can range from mildly annoying to completely debilitating.
The term “brain fog” can refer to isolated or minor cognitive effects that last hours or days. Still, it can also refer to significant, constant, and debilitating cognitive struggles.
What Causes Brain Fog?
Brain fog isn’t a specific medical diagnosis, but a side effect of an emotional or medical condition.
Your mental muddiness may be for more common reasons:
- Stress—Stress impacts the entire body—the brain included. When stress becomes chronic, it can negatively affect the brain, inhibiting it from functioning at an optimal level.
- Lack of sleep—Another obvious, but often overlooked, cause of brain fog is lack of sleep. Sleep deprivation interrupts the brain cells’ ability to communicate with one another, resulting in a lack of focus or clarity. More severe sleep issues, such as sleep apnea, can also cause brain fog and cognitive decline.
- Hormones—Menopause is known for wreaking havoc on the brain. The drop in estrogen levels can trigger memory and concentration issues. Hormonal changes are also known to exacerbate sleep deprivation, which may contribute to brain fog. Learn more about menopause and brain health.
- Diet—Some food allergies have been shown to contribute to brain fog. In addition, a vitamin B12 deficiency (which supports healthy brain function) can drive brain fog. Depression and fatigue are noted as common symptoms in research studies.
Medications—Medications, especially psychiatric and antibiotics, can have side effects that impact brain performance. This is especially common in older adults whose metabolic process is slower, making them more sensitive to medications.
When Should You Be Worried about Brain Fog?
A sign that your brain fog may be cause for concern is when memory problems and other cognitive issues interfere with normal functioning. People with mild cognitive decline and/or early stages of dementia may find they have difficulty completing simple, everyday tasks like paying bills.
This infographic from the National Institute on Aging details some common differences between normal aging and signs of serious memory loss.
Brain Fog and COVID-19
Experiencing brain fog long after recovering from COVID-19 is common. As Aviv physician Dr. Mohammed Elamir, MD, FACP, explains, there is a link between where the COVID-19 virus attacks the brain and how that impacted location affects long COVID symptoms.
If you’ve had COVID-19 and haven’t felt the same since, reach out to a trusted physician.
Your physician may ask about:
- Your current physical activity levels
- Medications or supplements you’re taking
- Possible nutritional deficiencies
- Possible infections and inflammatory diseases/conditions
- A timeline of symptoms
- How symptoms have changed over time
Your doctor may also request a blood test, CT scan, or advanced MRI.
What Can You Do to Fight Brain Fog?
Brain fog may be a sign that your body isn’t operating at peak performance, much like when you get sick with a cold or flu. The brain needs constant oxygen, the right supply of nutrients, and rest in order to function well.
When we fall short in one area of health, it’s easy to spiral out of control. Looking at the list of causes for brain fog, the cycle becomes clear: lack of sleep can lead to stress, which can lead to poor diet, and so on.
Often, the key to managing brain fog lies in good self-care. To ensure general health and wellness, try to:
- Manage stress—Many people find meditation helpful in dealing with stress.
- Eat a variety of healthy foods—Maintain a diet rich in vitamins and nutrients.
- Get enough sleep—What qualifies as a “good night’s rest” varies from person to person, so figure out what is right for you and stick to it.
- Maintain physical activity—Exercise has proven benefits for the brain. Start with 30 minutes per session, three days per week.
- Drink enough water every day—Some cases of brain fog are due to simple dehydration.
- Challenge the brain with games, puzzles, or novel experiences—Here’s a free brain training game to get you started.
- Try intermittent fasting. Many report that intermittent fasting helps clear brain fog and sharpen the mind.

Does High Blood Pressure Cause Memory Loss?
We all know that high blood pressure can cause a host of other health issues, although most of us are unaware that high blood pressure can cause memory loss. Cognitive decline is a side effect that isn’t always discussed. But having high blood pressure can directly affect your cognitive function, causing problems like brain fog and forgetfulness, as well as severe cognitive issues like vascular dementia.
Nearly one in three Americans and two-thirds of adults age 60 and older have high blood pressure, making it one of the most notorious killers in the United States. Fortunately, there are actionable steps you can take to manage your blood pressure, no matter your age.
Treatment options, such as the research-based hyperbaric oxygen therapy (HBOT) protocol available at Aviv Clinics, target associated health challenges like post-stroke, and age-related cognitive decline. Keep reading to learn more about how high blood pressure can cause memory loss, plus what you can do.
What Is High Blood Pressure?
Also called hypertension, high blood pressure occurs when the force of the blood pushing against the walls of your blood vessels is too high.
Every blood vessel in your body requires a certain amount of pressure to stay intact. High blood pressure may damage arteries, making them less elastic. Lower elasticity slows blood and oxygen flow to vital areas of the body. Health problems happen when your blood pressure wanders outside the acceptable range.
The higher your blood pressure, the greater your risk for health problems like heart disease, heart attack, and stroke. It also increases your risk of cognitive problems later in life.
What’s An Acceptable Blood Pressure?
Normal blood pressure levels differ for every person and depend on age, weight, and other factors. According to the American College of Cardiology and the American Heart Association:
- Stage 1 hypertension occurs at 130/80 mm Hg
- Stage 2 hypertension occurs at or above 140/90 mm
High blood pressure is unique because it doesn’t present symptoms on its own. The only way most people even discover that their blood pressure is high is when something more serious happens, like a clot. The best way to learn whether your blood pressure is at a healthy level is to measure it with a blood pressure machine at a doctor’s office, pharmacy, or on a home blood pressure machine.
Tip: A home blood pressure device is a worthwhile investment to monitor your health. Take your measurements at the same time every day for consistency, as your blood pressure will naturally rise and fall during the day.
How Exactly Does High Blood Pressure Impact Memory Loss?
The brain receives roughly 20–25% of the body’s blood supply. When high blood pressure causes the supply to decline, the brain lacks the nutrition needed to perform at optimal levels.
High blood pressure can also harm the tiny arteries that feed “white matter,” or the wire-like cells that transfer information to different brain areas. These issues may manifest with memory problems, confusion, lack of concentration, and other side effects.
Age-related cognitive decline studies show having high blood pressure during midlife can affect cognition later in life. We’ll let these research studies help clear the fog on the link between the brain and blood pressure:
- In this study, men at an average age of 78 years logged their blood pressure. After adjusting for biases like prior education and age, the men who performed the most poorly on the test were those who had experienced high blood pressure in middle age. This suggests a direct connection between hypertension and cognitive decline later in life.
- More recent studies have helped to reaffirm the connection between hypertension and cognitive decline. Researchers found mental processing speed and executive function were the top two cognitive skills most affected later in life.
High blood pressure directly increases the risk of developing vascular dementia—a type of dementia caused by blood flow problems in the brain from strained blood vessels. The strain on the blood vessels makes it difficult for the brain to get the oxygen needed to function correctly.
Fortunately, vascular dementia symptoms can be improved through hyperbaric oxygen therapy (HBOT), such as the type available at Aviv Clinics in central Florida. HBOT works by delivering oxygen directly to the brain in a pressurized environment. The direct supply of oxygen allows the damaged blood vessels in your brain to heal, helping you regain some cognitive functions.
How Can You Manage High Blood Pressure?
While medication is often the first thing people think of, investing in your health via lifestyle choices and research-backed therapies is really the best medicine for managing high blood pressure.
The absolute best things you can do for your high blood pressure and brain health are the following:
- Eat a clean diet of whole foods to promote your gut health.
- Exercise to help maintain or manage your weight.
- Get enough sleep by establishing a bedtime routine, working up a sweat, and turning off the TV.
- Engage your mind by gardening, reading, or even playing a video game with your kids or grandkids.
- Reduce and manage your stress levels with activities like yoga or meditation. Practicing mindfulness meditation can help you stay grounded in the present moment and reduce stress.
- Seek unique and comprehensive therapies, such as hyperbaric oxygen therapy (HBOT). Research-backed HBOT programs, such as the one offered as part of the Aviv Medical Program, encourage damaged vessels to heal and cognitive functions to improve.
Aviv’s unique protocol may include HBOT, along with cognitive training, dietary coaching, and physical performance training. This holistic approach has been key to restoring our patients’ optimal health.
