6 Ways Brain Fog Can Affect You

Brain fog can be just as debilitating as the fatigue you get with any chronic illness, but it is so misunderstood! There are a lot of symptoms within brain fog that many people don’t know about – yes, symptoms within symptoms! Here are 6 ways that you could be affected by brain fog.

If you want to read about other symptoms of ME/CFS you can do so here.

Inability to Think Clearly

This one is probably the biggest one for me and covers the following areas of brain fog too. It is literally an inability to think clearly. Imagine waking up in the morning – you feel groggy don’t you? You have to take a few moments to put your thoughts together. Now imagine having that 24/7. That is brain fog.


This one is a fairly obvious one right? People with brain fog, get confused, it’s as simple as that. It might not make sense to you as to why I am confused, but if I am, it’s because of brain fog.

Memory Loss

Memory loss is particularly bad when my ME/CFS flares up. Things you know off the top of your head you can suddenly forget! I have to write everything down otherwise there’s no guarantee I will remember. I tend to put everything in my phone calendar AND in my actual diary, as well as writing really important dates on my wall calendars!


This one I notice towards the end of the day when I’m getting tired and lethargic. I can be talking to someone normally and all of sudden all that comes out of my mouth is complete gobbledegook! I will get the words in my sentence completely muddled, I can stutter like crazy and all I can do is stop, and start again. Anyone that knows me may have noticed it happen, so if you have, now you know it’s just brain fog kicking in!

Word-Finding Difficulty

Word-finding is the most annoying symptom I think. I can get to the middle of a sentence and suddenly stop and have no idea what comes next and then I’m stood there looking like a fool trying to find this magical word that will complete the sentence! To make things worse, these words are usually the simplest, most-used words in the dictionary!


Concentration (or lack-of!) really affects me, especially when it comes to studying/revising. I can’t concentrate for more than 45 mins and even that is a push for me! The days where I could sit for hours at a time doing work are long gone! Also, say goodbye to multi-tasking if you suffer from brain fog!

This lack of concentration means I struggle to read books for any length of time, I can’t watch TV for too long, I can’t study for too long. It also means on a really bad day, my lack of concentration can affect simple things like texting or even watching Friends! 

I really hope this post has helped anyone with brain fog or anyone who didn’t quite understand it!

Have you struggled with brain fog?

Until next time,

    This post gives really great insight into brain fog. I had no idea of the variety of symptoms that this has.

    Never heard of this brain fog before, wonder if I don’t have it, just thought it was old age starting.

      Well I’m only 20 so I hope it’s not old age for me! Glad this has helped you and thanks for your comment!

    I know a lot of people have this from chronic illnesses but I am getting it more and more due to my age. I am using essential oils, vitamins and exercise to try and hold it off..great post.

      I love essential oils! I like to use Rosemary oil to help me focus and concentrate! Thanks a lot for your comment!

    I agree with these facts but would Aldo include the inability to multi-task. I used to be quite adept at it; however, I need every bit of concentration I have on one thing at a time now.

      I’m completely agree with you there! Thanks for your comment!

    Excellent post. I dread to think how long it took you to write up lol. I’m doing a uni course too. In the final year and wondering how the hell I’ll get through all the reading never mind the writing. Sometimes I’m just running on willpower because there’s nothing else. Xxxx

        Thank you so much for this article. LDN is really working for many of us who suffer from the brain fog that comes with ME/CFS.

    I get brain fog as well. I thought it was because I had epilepsy but my neurologist said it wasn’t . Does medication help you? I have also been writing about it on my blog

    • 24th July 2016 / 2:06 pm

      I don’t currently use medication for my brain fog but when I was doing my exams and assignments I used essential oils to help with concentration!

    I’m a retired speech language pathologist with CFS/ME and you’ve done an excellent job of outlining the effects of brain fog. I’d just like to add a couple more. It can be increasingly difficult to understand or process what people say. Sometimes you’re sure you’ve understood what someone said and you find out you have “misheard.” Also, brain fog can effect your ability to spell and to do math. When you are tired or sick, brain fog gets worse. The technical name for the parts of brain fog that involve language in spoken or written for and math is aphasia.

      Thank you! I’m glad you’ve enjoyed my post. Those are good points actually, I may have to include those in an updated post! Thanks for your comment! X

    Have you found anything that helps? I am really looking for an answer to my problems. I suffer from it 24/7 365 a year. I never realised before now that I had it because I thought it was normal. I think my epilepsy causes it but neurologits have not found a cause. good luck and let me know how you get on. I also describe it in my blog although I think that for everyone it is different sharonrossblog.wordpress.com

      Hi, there are a few things I can do to help but when it is really bad I tend to just try and accept it and rest because that is a pretty clear indicator that I need to! Thanks for your comment! Xx

    Hi Amy
    I have been suffering with brain fog recently & it just felt like i couldn’t do normal things because my brain literally just doesn’t function! 😕💨 I felt incredibly stupid because the tasks I couldn’t do were so simple to everyone else!! I have now realised that brain fog is a real condition which shouldn’t be overlooked. 😐 I seem to be over it now but I am all too aware of the symptoms & how I need to look after myself to prevent it happening again. 💕 I hope your brain fog doesn’t cloud you too much Amy xoxo
