Current research suggests this is a misconception. The whole % of brain thing is a gauge that is misused because we really do not know the full capacity of the brain to start with.

My sister had hydrocephalus due to the misuse of forceps during her birth. She got a shunt like C.N but the damage was done and her brain was not able to adapt. She is severely disabled and requires full-time care. It's fascinating to see how different the outcomes can be in these cases and how much we still have to learn about the brain.

[@Sciencerely]

I'm sorry to hear that, I hope your sister, your family and you are doing well. Yeah, the case I have presented here is really rare and it's not clear why there was a nearly full recovery. But it is amazing how neurons can rewire themselves!

That’s why Diagnosticians get the big bucks. Any disease state exists within thousands of bodily systems and uncommon conditions need to be carefully considered with an in depth understanding of said systems and all the ways they interact or impact each other. People die and are injured every day due to misdiagnosis, or mismanagement or misapplication, it’s unfortunate and unavoidable. We are just too complex for medicine to be an exact science. Figuring out how her injury impacted her differently to others would be an educated guess at best.

Would love to know anatomically what parts of his brain were left.

[@ArrowsSpecter]

i think most of the parts were there, they were just all squished up against his skull. That or the remaining parts of his brain took over for what was missing, like how someone missing a brain hemisphere can adapt to still function as their remaining hemisphere took over the functions of what they lost.

[@ferid9k]

Read the publication it's in the description

[@saraknox1631]

I have a friend who had a similar issue with severe hydrocephalus. @ArrowsSpecter is right, all parts of the brain are present, just pressed against the inside of the skull, with very large empty spaces inside the brain. In my friend's case, he had an ADHD diagnosis, and that was the only evidence that anything may have been wrong. He only got the brain scan because of a head injury that was unrelated to his hydrocephalus.

[@starfirei3356]

In utero, the umbilical cord wrapped around my neck, and my brain came out of it with severe deficiencies in most areas. Some known ones are stress, memory/recall (two different defects), emotional recognition and processing, conscious thinking, awareness of bodily needs, sense of smell (likely neurological, as shown by other circumstances), and probably others that I’m not realizing. But, somehow, all of those were stabilized to some degree. They all became progressive, in that they had less of an effect when I was yr, and only really started showing when I was old enough to know what they are. The stress one was kept out of my conscious thinking, and given a reverse scaling: the more stressful a situation should be, the less I am. This is helpful because stress has a physical effect on me. The memory/recall defects did not present until a year ago (I’m 18). The emotional recognition and processing defects made it so I couldn’t feel emotions consciously, however my brain made it so I could still feel them subconsciously. Still have no emotional recognition, but sometimes I can make an educated guess. I have a tendency not to think, but all mental processes are translated directly into actions by my body, so I don’t have to. I’ve learned to actually think in recent years, though. Awareness of bodily functions was reduced, but not completely. My sense of smell is interesting though. It didn’t fail outright, but it’s effectiveness and range was severely reduced. And to compensate, my sense of taste was heightened. Yes, I know that shouldn’t be possible, but that is the case. And then there’s one big one: the neurons in my brain and my nerves are weaker, so they accumulate damage more easily. In addition to any damage farther farther than my neck being automatically healed, somehow my brain prevented damage for 14 years of my life. I still don’t know how, nowadays it’s not too uncommon. And the biggest way it was stabilized: I have the ability to fix it myself. I made heavy use of it last year, when I dealt with both damage and defects. I had figured it out a year before that, when an old bit of damage from when I was 15 flared back up again. This should be a miracle, all things considered. I don’t know how it happened. But whatever caused all of that, it’s still around. That I’m sure of, or I would have shown clinical signs for brain swelling in December of 2022. I’m just glad to be alive.

[@peytoia]

oh wow. this is making me realize some symptoms i attributed to just me being weird may be related to my brain injury as well. specifically the sense of smell and my struggle to interpret signals from my body like needing to use the bathroom or eat until im like taking damage from it

[@alysonsylva]

I am so sorry about your grandfather. Can you tell me a little bit about him like how old he was when he started showing symptoms and if anyone else in his family had similar problems. The only reason I am asking you this is that I have been tested for the Alzheimer's Gene and I have it from both of my parents. So does my brother. I have been in clinical research studies for the last 12 years and I have been taking college courses and trying to study law and testing my brain. I'm 66

[@alysonsylva]

If he was in his eighties or nineties, nearly everyone get dementia no matter how hard they study or do puzzles

[@bramstedt8997]

That sucks. My grandpa had Alzheimer’s. His was probably caused by radiation treatment for his brain cancer. Hoping there wasn’t a genetic component, but unfortunately that’s often the case. I’m sure environmental stuff like high lead exposure also contributes. Seems that puzzles and such can still decrease risk but a decreased risk is still a risk

Okay, KZbin, why are you showing me a video with a thumbnail of guy whose nine-tenths of the brain missing, when I am busy watching videos about my country's failed self-coup attempt?

[@azuki-c-s]

[@NEKRWSPHERE]

Do you know what the problem is with the studies you mentioned that supposedly show that learning new skills "prevents" Alzheimer's and "milder" forms of Dementia? The problem is that in most cases we are unable to draw causal inferences. We don't know exactly how to interpret the correlation. It could be that (for example) an unknown THIRD factor is both predisposing a person to learn new things often AND also has neuroprotective functions. I remember us covering this topic in school rather extensively., and it's not as easy as lay people often think, to design studies which would clearly establish a cause and effect relationship in this case. This, of course, doesn't mean that you should stop solving puzzles, learning new languages or doing other cognitive exercises as you age. In fact I often try to convince my mom to start solving puzzles rather than watch KZbin videos like yours., just in case this in fact does help her to retain her cognitive faculties longer. Unfortunately I'm probably too late, because she is already at the stage where she fails to appreciate what a terrible thing a mind is to lose. 😢

Apparently autistic people don’t go through the same level of neural pruning as non-autistic people, meaning we actually have more brain cells. I wonder if this also means we’d be better at recovering from brain injuries?
