Brain Fog Causes and Natural Remedies

Brain Fog

What is brain fog?  What causes it? Are there natural remedies for this condition?  These are just a few questions we are about to cover in hopes of bringing you relief from this all too common health concern.  

Brain Fog is Not a Medical Condition

It is a state of confusion and forgetfulness.  There is not a blood test to diagnose but there are is a symptom checker list. It involves a series of symptoms that are related to your cognitive functions.  

Although there are many symptoms, brain fog feels like an overall sense of not feeling as your normal self.  How long brain fog lasts depends on the reasons it occurred. Home remedies range from supplements to dietary adjustments.    

Causes of Brain Fog 

Questions about brain fog

There is not one set of reasons a person may experience trouble with focus, memory and concentration.  There are many reasons for brain fog. Below is a list of well-known causes. 

  • Irregular sleep patterns
  • Poor diet and nutrition
  • Pregnancy
  • Menopause
  • Blood sugar levels
  • Depression or anxiety
  • Attention Deficit Hyperactivity Disorder
  • Chemotherapy (1)

Brain Fog Symptoms 

Confused and tired with brain fog

These will vary from person to person and may include but are not limited to...

  • Fatigue
  • Aphasia - “losing your words” while speaking
  • Confusion/cognitive decline
  • Memory loss
  • Lack of concentration
  • Lack of patience - you become irritable more easily
  • Anxiety
  • Depression
Irregular sleep patterns cause or worsen the effects of brain fog.  When your brain is deprived of sleep it does not have the opportunity to recover from today and prepare for tomorrow.  If you have trouble falling asleep, you may notice a fog the next day. 


Studies have shown a direct link between untreated sleep apnea and brain fog. (2) Overall memory may not be severely impacted but recalling specific details of it will be. 

Exhaustion and fatigue with brain fog
Fatigue is a feeling of being overly tired; mentally and physically.  Symptoms of fatigue occur when your energy levels are depleted, concentration is impaired and decision-making becomes difficult.   What tires one person may not another. This makes symptoms challenging to diagnose. 


Aphasia is a term that covers a deficit in language.  The word on the tip of your tongue situation.  

Occasionally this is normal.  If it occurs more often, it’s important to evaluate the reason(s). It is frustrating to communicate when the words just won’t come to you. 

Cognitive decline is something we all deal with.  Sometimes it is just a momentary issue but others it seems to take over.  

Repeatedly looking at an apple and calling it an orange?  Can’t seem to figure it out? That may be more than day-to-day confusion.  It could be part of a bigger underlying issue.  

Memory Loss happens to everyone from time to time. A sign it may be more than normal is when the lack of memory makes it difficult for you to carry out your daily activities.  Work becomes harder, home life is frazzled and communication is awkward.

Lack of concentration can make school, work or even just relaxing with a good book, difficult.  It is hard to accomplish pretty much any task without the ability to focus.  Learning and memory go hand-in-hand.

Lack of patience due to brain fog

Limited patience may result from your frustration over the state of chaos your brain is in.  Sometimes a little physical activity can help get you back on track. It may not be a long term solution but will give you a much-needed break to gather your thoughts.  

Depression and Anxiety are a complex issue when discussing this topic.  Each may be a symptom, a cause or even both. When your nervous system is not operating at its best, there is a long chain of reactions that happen.  Your mind does not process information as it used to.  

Who can suffer from this condition?

Anyone.  This condition is not determined by things like genetics, age, ethnicity or health conditions.  There are many situations that bring it on.  

Maybe you are overstressed and experience a lack of clarity.  You may be older and take a medication that induces an altered memory.  Your diet may help or hinder your memory. There are many factors to consider when determining why you are experiencing this frustrating issue.  

Women experiencing menopause or pregnancy often report a state of brain fog.  We have all heard the phrase, “pregnancy brain”. Hormones have a direct effect on the human brain.  During these times in a woman's life hormones are fluctuating at an abnormal rate.  

Diabetes patients also suffer from a loss of concentration and recall.  The irregular blood sugar levels affect the brain just as the hormones do. Some diabetics report they can tell if their numbers are off balance from their state of mind.
