Why Can't We Figure Out What Causes Chemo Brain?

[@coralee5628]

I've had substantial memory issues for the last decade. It seemed to start with my cancer treatment, but I had no idea that other cancer patients had it or that it was actually a documented issue. I always learn so much from SciShow!

my aunt had chemo brain! I never knew it was a thing other people experienced, I thought it was just being exhausted from such intensive treatment.

[@arthas640]

Some people can have personality changes, mood swings, and other drastic side effects but it's mostly a memory problem that most people get. An oncologist once told me chemo brain can act like a head injury or brain damage when it comes to side effects.

[@eliscanfield3913]

Yeah, my sister has this. She's on chemo and complains about the chemo brain sometimes. Mind you, she's more than a decade passed her original Stage IV diagnosis, and several years after the remission, years where she's gotten to see her newborn grow into a tween., so she definitely likes that part.

I'm having chemo for ovarian cancer right now. I have a good outlook, so don't worry. However, I've noticed chemo brain in two quite specific ways. I struggle to recall words that I don't use frequently (usually I have ver fluent conversations). Also, I'm struggling to make small decisions, whereas I usually just make them and move on. I'm very glad it'll go when chemo is finished.

Ther are apparently several options but it's a manage as a chronic disease for a while and with the reductin of it fromt he original chemo, I feel much more energetic and with the chemo brain gone, I'll be able to work again, so that'll be just wonderful.

I had horrible chemo brain with my treatment for stage IV colon cancer, and even had significant trouble a year after completing treatment. My brain has not ‘bounced back’ even after two years.

Hey, thanks for doing this video. I’m going through chemo now and chemo brain has made parts of my life incredibly frustrating. The forgetfulness is one thing, but at times it has been difficult to access my full vocabulary. As a college instructor, this can make things difficult to perform my job when I “know” the right word, but can’t access it to speak it. Thankfully there’s always more than one way to explain things, it’s just not as fluid as it was 18 months ago. Even my therapist was unfamiliar with chemo brain. So hopefully going forward, more people will be able to acknowledge, cope, and be able to adapt to the changes that go on in the brain, whatever the cause may be.

[@Drksparrow]

I went through chemo last year. And I've also have had an incredibly hard time accessing my vocabulary as well. I'd be able to see the image of what I want to say but not the word. It's so annoying, and sometimes ppl don't have patience to wait for what I want to say. It's at least once a day. Sometimes I'll end up just describing it instead, if it's possible. But I do get the word eventually just takes me a minute. But I wonder how much worse is going to be as I get older. I'm only 31. I hope it gets better for you, especially since you're teaching.

[@ManfredDudesonVonGuy]

The real question here is where does the risk outweigh the benefit of the treatment. I think, based on what I've researched in the literature, that anesthesia is a net benefit to the general population. I for one am glad to have had anesthesia while my wisdom teeth were ripped out and my shin put back into place after a football injury saw it poking through my skin. I experienced no long term side effects, and the scientific literature supports that my experience is the norm. Despite bad effects suffered by some individuals, the risk-benefit analysis is massively in favor of anesthetic use.

[@altrocks]

@@ManfredDudesonVonGuy That's absolutely not the real question here. No one is talking about banning anesthesia or getting rid of it. We're talking about how lots of medications and treatments have unintended cognitive side effects for a lot of people and how it's often overlooked.

For reference for my following rant: I am 5 (coming up on 6) years cancer free When looking back on when I went through chemo, I always realize how foggy my memory is of that time and the months following, I still feel like I struggle with dumb memory things One thing I’ve always been frustrated with post-cancer treatments is when I still have various (and seemingly random) health issues, and so many doctors will just brush it off saying “oh that chemo and radiation is nasty stuff” but this has become my constant, regardless of what I’m struggling with, if there isn’t an obvious answer the doctor just blames it on my cancer treatments

Just leaving this comment to cheer things up a bit. When Hank said "in it" I had a flash back to my school days: for some reason everybody was saying "in it" at the end of their sentances all the time - like "yeh like you've got to serve the blancmange could though in it" where "in it" means "haven't you" of course. Like just as bad as "can you borrow me your phone" rather than "can you lend me your phone" - of suggesting that one's phone belongs to them and you are their slave. A lot of people got punched.

[@ginnyjollykidd]

Thanks for talking about this. It's been almost 2 years (this August) since I finished chemo and radiation for my breast cancer. The doc put me on the harshest chemo- and I agreed- due to my otherwise good health. I wanted to hit it hard and hit it fast. After 4 treatments (they laid me out!), they switched me to a more tolerable chemo. I think there need to be studies done on whether the less - harsh Taxol is a effective as A/C, and if so, maybe A/C needs to be retired or its use modified. Studies are being done on chemicals called Catechins which cause cancer cells to go through the dying cycle. Catechins don't seem to bother healthy cells, so that would be a plus. Meanwhile, when you visit your grocery's produce, follow your gut and your cravings. Don't try to eat citrus fruits if your body says "no way!" if it's vitamin C you're after, then you can get it in all fresh fruits and vegetables. But if you have a craving for a particular kind of produce, more than likely it means there's something in it that you need, and if you look it up on the Internet, most likely some study is done with it in connection with cancer.

[@Jake12220]

We already know many memory related problems stem from the buildup of certain proteins and 'junk' accumulating in the brain.we Also know that sleep is important for the removal/cleanup of these things under normal circumstances. Add to this many chemo patients have trouble sleeping and it looks like a likely cause of the memory issues, including why they can last so long. Not saying this is the reason but it would seem like an obvious first line of enquiry. Personally l would start by assessing if there is a correlation between reported memory problems and problems sleeping and if there were then conduct a study using sleeping aids(pills, or simply strategies to teach people to sleep better) then compare groups to see if better sleep had a clear effect on memory or not. Of course lots more follow up work would be needed but definitely seems like an obvious way to start.

[@theherald4340]

It's a nerve agent. And when it spreads through the body it "numbs" some nerve receptacles somewhat. I watched my father go through it, before he died; And I as well for a short time. But the long range effects are in the extremities. The hands and bottom of feet. Heck! I used to run and play basketball. But since the chemo's lasting effect, I'm afraid to take full running strides for fear I'll flop an ankle. My reaction time, is slowed. The hands can't properly feel the ball on occasion. But; I've been in remission since 2013, so that is good. With Chemo, there is a trade off. You may live through it; but you lose other things that are part of a quality of life. And they always tell you it's about quality of life. I guess it depends on each persons perspective.

Most chemo drugs do not cross the blood brain barrier. I had to receive intrathecal chemotherapy to get chemo directly to the spinal column for this reason.

Ever heard of pregnancy brain ? I have had it and this sounds similar.

Hi Joy. I think you like science, so I would like to recommend my channel. I'm starting at doing science videos with motion graphics, and I think you are going to like it if you give me one opportunity. Thanks for your time ^^

SciShow After hours is that a rehash of HFS?

[@nintando]

scishow tangents is more like hfs, after hours is much shorter

This is phenomenally slow grasp for research, when we already know that the trickle of new neuronal emplacement underlies memory formation in the hippocampus. That would mean chemo's assault on dividing cells is affecting the stem cell progenitors still active in neurogenesis, apparently across multiple brain regions. Actually this means more neurogenesis in brain regions where it has been yet to be confirmed, like the coordination effects meaning populations in the cerebellum!

I hate when that happens because one time I came up with a great character to draw but then I just suddenly forgot about it and remembered it a few months later

[@tammycarlockrealtor5324]

It’s not that difficult. People who do drugs can get brain damage. So why wouldn’t dumping gallons of toxic chemicals into a persons body have the same effect? I had an amazing brain prior to chemo. I never had to write anything down because my memory was superior compared to the average person. They’ve known there’s non toxic ways to reverse cancer for many many decades. Yet they refuse to use these ways. And they continue to find new chemicals to use for cancer treatment.

So treating cancer gives you ADD.

Having 2 rounds of deadly chemo for a stem cell transplant... yea it is a thing. Can't remember names, for example. I could tell you all about a person or thing - everything, but the name.

Just put my brain in a jar and feed it oxygen, glucose, and information. Also, remove all the gunk my brain cells produce

[@4G12]

You forgot the critical fats, proteins, minerals and vitamins.

[@nicolaiveliki1409]

@@4G12 I guess if it were easy to sustain a human brain outside of the body, we'd be doing it ;-)

Who knows someone who's undergone chemo🙋

[@AlthenaLuna]

I've gone through it. Repeatedly.

[@nyctodrome6187]

how does this comment contribute to conversation at all?

[@AlthenaLuna]

@@nyctodrome6187 I know someone who's gone through it because I'VE gone through it...how is that unclear?

@@AlthenaLuna I don't think the reply was targeted at you, you're fine.

Myself. I have been through it.
