    hi there,
    So I know that a CFS patient can crash after certain types of exertion, obvious ones being physical exertion, stress, emotional upheaval, over-stimulation or eating the wrong food. The question i have is about crashing after *mental exertion*, the kind of exertion you would do when reading a textbook or solving math problems.

    Recently i have been going through the worst crash since my CFS started and im trying to understand what happened by tracing my steps. It all started when i was doing much better and decided to go back to try to study some textbooks from my university years. I was studying only on the weekends but it was about 6 hours a day of pretty intense mental work. Gradually i got worse and even after i stopped i have been continuously declining to the point that now i am finding it hard to go to the bathroom.

    Of course, it could have been something else, but do you guys think this type of mental work could cause such a severe crash? have you ever crashed from studying/reading? I have a hard time believing mental exertion could cause such a massive crash!

    Thank you!

    Yes, definitely, I took an intense course a few years ago and crashed mentally.
    I think that my CFS (& Lyme) affected my neurotransmitters and my HPA axis.
    For mental energy help I took Aceytl-L-Carnitine for while.
    You have to be very intentional about mental rest , sleep etc... when on such a course.

    Mental exertion can absolutely cause a relapse, just as easily as physical exertion. I don't think that it is at all uncommon. And it doesn't take much "exertion", be it physical or mental. For myself, I could more easily walk for probably a mile than I could carry on an active conversation for 15 minutes without getting myself in trouble. I also no longer read any significant amount, listening to audio books to avoid the mental exertion of reading.

    You are right. If i survive this hopefully and can go back to being near my baseline, I will be sure to always take breaks when studying. Like 30 minutes work, 30 minutes rest.

    The weird thing is that i can spend countless hours doing idiotic things on my phone, like watching funny cat and dog clips on youtube and it never causes me any problems, but when i start reading or exerting mental effort to focus and process complex information, then my brain feels the crash.

    yeah mental exertion is bad
    some days I get bummed out and play videogames all day or go to my friends house or some other reckless use of energy and I'll wake up the next day feeling, well, not good by CFS standards but decent, but if I spend a few hours on one of my good days reading something that takes focus and concentration I'll be dead tired the next day

    It's bad cause I really feel like I need to get something done but I just can't without burning out my energy or I'll try to recoup my energy on a day where I'm dead tired but feeling so bad in bed all the time my patience will burn out, I'll go mad from only being able to listen to audiobooks or watch shows which would be entertaining if I just had energy but are painful to have as my only escape when nothing feels good, I'd probably be more productive if I was doing drugs and was able to just lie there sedated the whole day to get my energy back, being sick like this is bizarre

    Mental exertion seems to drain me more than standard physical exertion. It's also always the first thing I need to cut back on when going through a crash or relapse.

    Hope you can manage to rest and recuperate enough to continue with your studies!

    Yes. I have often crashed from reading too long or working too hard - especially at night.

    This is passive entertainment. Studying is active.

    I got completely wasted after a 90 minute first appointment with my ME doctor, too much focus required for speaking in a foreign language and discussing medical issues.

    I watched a fascinating talk by Dr. Nicholas Gonzalez on DVD re cancer one night - it took about 3 hours of intense concentration, and I was crashed the next day. Generally I stick to reading murder mysteries, light TV --

    Different mental activities require different amounts of neurochemical resources, and produce different amounts of hormones and other neurochemicals, any of which can affect ME/CFS. For me, socializing can cause a crash, and driving can too; I think it has to do with the sustained alertness level. I haven't noticed reading being a trigger, but maybe that's because reading is a major part of my life. I've always been a walker and reader, so those 'muscles' are fit for their tasks, and don't trigger ME symptoms. I haven't specifically tested intellectually challenging reading, such as studying a textbook for an exam, but normal textbook level reading isn't a problem for me. However, if my ME symptoms are high, I lack the mental energy for reading.

    So no, you're not crazy. Mental exertion definitely can cause an ME/CFS crash. It most likely hasn't caused any long-term changes, so you should get back to baseline once you've stopped triggering the crashes. You do have to learn your limits though. That takes time, and suffering from more crashes.

    Yes, you are right about mental exertion causing PEM.

    I have learnt that I need to pace both my physical and mental exertion. If I need to do something mentally taxing, I will need to take it very easy next day. I think the resulting PEM is not usually as severe as for physical activity and I will not have the leg pain . If I do have PEM from mental exertion I need to stay in bed all day until I start to recover and am usually ok by the following Day. Note that ‘ mental exertion’ icludes things like trying to sort out my tax , writing and social chatting outside my ‘comfort zone’.

    As with @Wishful, reading has been my life so , unless it is really difficult and technical stuff, book reading is generally fine for me.

    although, I need to avoid a lot of the highly technical biochemistry found in some of the PR posts. No way am I going to have the energy to try to understand all the arguments relating to this disease, so I am pleased to leave that to the experts.

    But I am fine with complicated genetics and microbiology in plant diseases and soil microbes. It’s just what you are used to I guess.
