Conditions
Many people describe their thinking as cloudy, slow, or effortful: trouble finding words, forgetting why you walked into a room, or feeling mentally spent after tasks that used to be easy. This page explains what brain fog is, what can cause it, and how we approach it at Strong Tower. It is general information, not a diagnosis.
Sudden confusion, trouble speaking, sudden weakness or numbness, or a sudden severe headache should be treated as an emergency. Call 911 or go to the nearest emergency department. Memory or thinking changes that are new, getting worse, or that disrupt daily life should be checked by your doctor promptly.
Cleveland Clinic describes brain fog as a group of symptoms that affect thinking, memory, and concentration, including trouble focusing, confusion, forgetfulness, slowed thinking, trouble finding words, and mental exhaustion. It is not a diagnosis on its own. It is a term for symptoms that can follow an illness, come from a medication, or point to an underlying condition. It is usually temporary but can last weeks or, in some cases, months to years (Cleveland Clinic, May 2024).
Cleveland Clinic lists lack of sleep, stress, poor nutrition, and hormonal changes such as pregnancy or menopause. It also lists conditions such as diabetes or low blood sugar, autoimmune disorders, anxiety, depression, ADHD, and autism, plus COVID-19, chemotherapy, and long hospital stays. Possible mechanisms include immune-related inflammation in the brain. It suggests seeing a provider if brain fog disrupts your daily life, you often forget appointments, or you struggle to complete ordinary tasks. Its self-care tips include better sleep, nutritious meals, about 30 minutes of daily physical activity, writing down important information, short breaks, and psychotherapy such as cognitive behavioral therapy (Cleveland Clinic, May 2024).
Because so many things can cause it, a medical evaluation is a good first step. That can include a review of your medicines, sleep, mood, and basic lab work.
We approach brain fog as a pattern to understand rather than a single problem. Clear thinking depends on steady blood flow, good sleep, and a nervous system that adjusts to mental demand. Some of our evaluation looks at how well the autonomic nervous system, eye movements, balance, and attention are working. If those are part of the picture, care is built around exercises designed to challenge the networks involved.

Memory and focus depend on sleep, stress, mood, and general health as much as on any one brain area. Forgetfulness and distractibility are common when sleep is poor or stress is high, and they can also come from medicines or other conditions. Memory problems that are new, getting worse, or affecting daily life should be evaluated by your doctor. We can look at how attention, eye movements, and balance are working alongside that.
Thinking that has not returned to normal after a head injury is covered on our Post-Concussion Syndrome page, including vision, headache, and sleep problems.
Processing speed is how quickly you take in and respond to information. Executive function is the set of skills used to plan, organize, prioritize, and follow through. Both can be affected by poor sleep, stress, ADHD, mood, medicines, and brain injury. If you notice slower thinking or trouble organizing yourself that is new for you, mention it to your doctor. We can look at what may be contributing from a nervous system point of view.
Cleveland Clinic lists COVID-19 among the causes of brain fog, and suggests it may relate to immune-related brain inflammation. Brain fog after COVID often comes with fatigue and trouble with exertion. If that sounds like you, see our Dysautonomia & POTS page, since autonomic problems can overlap. We see our care as complementary to the care you get from your doctor or a post-COVID clinic.
Not by itself. Cleveland Clinic calls it a term for symptoms that can come from many causes.
Often days to weeks, though sometimes months or longer, according to Cleveland Clinic.
Common causes include poor sleep, stress, hormonal changes, some medicines, and conditions such as diabetes, anxiety, and depression, as well as COVID-19.
If brain fog disrupts your daily life, you forget appointments, or you struggle to complete ordinary tasks.
Whether care here is a fit depends on what is behind your symptoms, which we look at in your evaluation. We see our care as complementary to your medical care.
