Found yourself looking for your phone while talking on your phone? Lost your train of thought halfway through a speech or story?\nThese scenarios are examples of \"brain fog\" — the feeling that your brain is cloudy or working more slowly than usual. More than\n28% of\nadults\nLink is external, Link opens in new window\nreport experiencing brain fog at one time or another — risk increases with age and is higher in females.\nThat does not mean everyone will experience brain fog as they age. But it is important to distinguish age-related brain fog from signs of serious cognitive impairment (difficulty with thinking, learning, memory and other brain functions).\nHere's what you need to know about brain fog and aging:\nWhat is brain fog?\nBrain fog, also known as \"mental fatigue,\" is marked by symptoms such as:\nDifficulty focusing and concentrating\nForgetfulness\nLosing your train of thought \nSlower processing time\nTrouble finding the right words\nThe cloudy feeling does signal a degree of cognitive impairment, but it is typically temporary and mild — it does not severely affect your ability to function. There are many\ncauses of brain fog\n, including:\nLifestyle factors,\nsuch as poor sleep, dehydration, stress or alcohol use\nIllnesses and conditions,\nincluding\nautoimmune conditions\n,\nCOVID-19\n, diabetes and hormone-related conditions\nMedications and treatments,\nincluding some sleep aids, pain drugs and\nchemotherapy\nEnvironmental factors,\nsuch as extreme temperatures and air pollution\nBrain fog and aging\nAs you age, your body and brain change. Typically, in your 50s and 60s, your brain begins to undergo chemical and structural changes, such as:\nDecreased blood flow\nShrinkage of certain parts of the brain\nReduced communication between neurons (brain cells)\nIncreased inflammation in the brain\nMany of these changes occur in brain regions devoted to memory. As a result, you may experience occasional brain fog. \nHowever, older adults are also at higher risk for chronic conditions and the most common causes of brain fog, including:\nDepression\nHormone changes associated with\nmenopause\nand thyroid disease\nSleep issues\nStress\nVitamin and\nmineral deficiencies\nIt's important to note that brain fog is different from neurodegenerative conditions such as dementia or\nAlzheimer's disease\n. They are all signs of cognitive impairment. But the symptoms of more serious cognitive conditions are progressive, not temporary, and affect your ability to function in everyday life.\nWhat helps with brain fog?\nThere is no clear way to prevent brain fog because the symptoms and causes are wide-ranging and common. However, you may be able to help prevent or reduce symptoms by making lifestyle changes, such as:\nBe social,\nwhich can offer mental stimulation\nEat a nutritious diet\nto avoid vitamin deficiencies\nMaintain healthy habits,\nsuch as drinking enough water, not smoking and avoiding excessive alcohol\nManage stress\nby prioritizing rest and self-care\nMove your body\nby engaging in daily exercise\nPractice\ngood sleep hygiene\nto improve sleep quality\nA\nstudy of nearly 3,000 older\nadults\nLink is external, Link opens in new window\nlooked at the benefits of five lifestyle habits: exercise, drinking in moderation, eating a\nMediterranean diet\n, not smoking and engaging in mentally stimulating activities. People who practiced four or five of these behaviors had a 60% lower risk of Alzheimer's disease than those who engaged in one or none. Adopting two or three of the healthy practices reduced risk by 37%.\nWhen you are experiencing brain fog, try taking short breaks to give your brain a rest. Adopt practices, such as writing things down and setting alarms, to reduce the impact on your daily life.\nWhen to see a doctor for cognitive issues\nMemory complaints combined with functional impairment are a cause for concern. Consult your primary care physician if you notice that the symptoms:\nInterfere with your quality of life,\nmaking it a challenge to be social, work or complete household tasks\nLast for several weeks or more,\nor increase in severity\nAny time you have concerns about changes to your thinking and memory, it's a good idea to speak with a health care professional. They can determine whether your symptoms are a normal sign of aging or possibly caused by an underlying health condition, medication or lifestyle factor.","attrs_markdown":"[Skip to main

However, you may be able to help prevent or reduce symptoms by making lifestyle changes, such as: - Be social, which can offer mental stimulation - Eat a nutritious diet to avoid vitamin deficiencies - Maintain healthy habits, such as drinking enough water, not smoking and avoiding excessive alcohol - Manage stress by prioritizing rest and self-care - Move your body by engaging in daily exercise - Practice [good sleep hygiene](https://www.uclahealth.org/news/article/sleep-hygiene-first-step-in-getting-a-good-nights-rest) to improve sleep quality A [study of nearly 3,000 older adults Link is external, Link opens in new window](https://pmc.ncbi.nlm.nih.gov/articles/PMC7455318/) looked at the benefits of five lifestyle habits: exercise, drinking in moderation, eating a [Mediterranean diet](https://www.uclahealth.org/news/article/mind-diet-created-help-protect-cognitive-health), not smoking and engaging in mentally stimulating activities. People who practiced four or five of these behaviors had a 60% lower risk of Alzheimer's disease than those who engaged in one or none. Adopting two or three of the healthy practices reduced risk by 37%. When you are experiencing brain fog, try taking short breaks to give your brain a rest. Adopt practices, such as writing things down and setting alarms, to reduce the impact on your daily life. ## When to see a doctor for cognitive issues Memory complaints combined with functional impairment are a cause for concern. Consult your primary care physician if you notice that the symptoms: - Interfere with your quality of life, making it a challenge to be social, work or complete household tasks - Last for several weeks or more, or increase in severity Any time you have concerns about changes to your thinking and memory, it's a good idea to speak with a health care professional. They can determine whether your symptoms are a normal sign of aging or possibly caused by an underlying health condition, medication or lifestyle factor. ## Take the Next Step If you are experiencing cognitive changes, reach out to your [primary care](https://www.uclahealth.org/primary-care) physician. ## Book An Appointment See a doctor, virtually or in-person, with our easy online booking options.

Readable Markdown	Have you ever walked into a room and forgotten why you went in there? Found yourself looking for your phone while talking on your phone? Lost your train of thought halfway through a speech or story? These scenarios are examples of "brain fog" — the feeling that your brain is cloudy or working more slowly than usual. More than [28% of adults Link is external, Link opens in new window](https://pmc.ncbi.nlm.nih.gov/articles/PMC11191638/) report experiencing brain fog at one time or another — risk increases with age and is higher in females. That does not mean everyone will experience brain fog as they age. But it is important to distinguish age-related brain fog from signs of serious cognitive impairment (difficulty with thinking, learning, memory and other brain functions). Here's what you need to know about brain fog and aging: ## What is brain fog? Brain fog, also known as "mental fatigue," is marked by symptoms such as: - Difficulty focusing and concentrating - Forgetfulness - Losing your train of thought - Slower processing time - Trouble finding the right words The cloudy feeling does signal a degree of cognitive impairment, but it is typically temporary and mild — it does not severely affect your ability to function. There are many [causes of brain fog](https://www.uclahealth.org/news/article/cognitive-health-isnt-just-about-mind), including: - Lifestyle factors, such as poor sleep, dehydration, stress or alcohol use - Illnesses and conditions, including [autoimmune conditions](https://www.uclahealth.org/news/article/ra-patients-can-have-higher-risk-of-mild-cognitive-impairment), [COVID-19](https://www.uclahealth.org/news/article/many-brain-fog-lingers-post-covid-19-infection), diabetes and hormone-related conditions - Medications and treatments, including some sleep aids, pain drugs and [chemotherapy](https://www.uclahealth.org/news/article/cognitive-issues-associated-with-cancer-treatment) - Environmental factors, such as extreme temperatures and air pollution ## Brain fog and aging As you age, your body and brain change. Typically, in your 50s and 60s, your brain begins to undergo chemical and structural changes, such as: - Decreased blood flow - Shrinkage of certain parts of the brain - Reduced communication between neurons (brain cells) - Increased inflammation in the brain Many of these changes occur in brain regions devoted to memory. As a result, you may experience occasional brain fog. However, older adults are also at higher risk for chronic conditions and the most common causes of brain fog, including: - [Depression](https://www.uclahealth.org/news/article/does-mom-have-dementia-or-depression) - Hormone changes associated with [menopause](https://www.uclahealth.org/news/article/many-women-have-cognition-issues-during-menopause) and thyroid disease - Sleep issues - Stress - Vitamin and [mineral deficiencies](https://www.uclahealth.org/news/article/why-iron-deficiency-women-often-overlooked-and-how-recognize) It's important to note that brain fog is different from neurodegenerative conditions such as dementia or [Alzheimer's disease](https://www.uclahealth.org/news/article/study-suggests-physical-activity-slows-alzheimers-disease). They are all signs of cognitive impairment.
