- Anton's Syndrome is the condition where someone thinks they can see, despite obvious signs that they suffer from cortical blindness: A case study by Madulla et al. (2009)
In this video in the 'Extraordinary Brains' series, we discuss a case study describing an 83-year old woman who was diagnosed with Anton's syndrome. This patient was found collapsed one day at her home, and was taken to the hospital. Upon examination, it was determined that she had suffered a cerebral infarction to the right occipital and left occipito-parietal lobes, regions important for vision. This infarction led the patient to suffer cortical blindness; a form of blindness that is caused, not by damage to one's eyes, but by bilateral damage to brain regions involved with vision.
Strangely however, although the patient was unable to see, she denied all loss of vision. Despite her blindness, she still behaved as if she could see, which caused her to frequently walk into walls and fall over objects. The patient showed signs of confabulation; the creation of false memories without any intentions of deception. Thus, she did not deliberately lie about her loss of vision. Rather, she genuinely believed that the false memories she created were true.
The woman was eventually diagnosed with a condition called 'Anton's syndrome', an extension of cortical blindness associated with a denial and confabulation of one's loss of vision. The woman was eventually released from the hospital, and moved in with family members. Although her physical condition improved over time, the likelihood of any substantial improvement in her vision was deemed low.

USE OF STOCK IMAGES AND VIDEOS
Occasionally we make use of stock images and videos (pixabay.com or pexels.com). We use these to make our videos more lively (better than looking at a blank screen). These stock videos should not be taken as an exact scientific reflection of the discussed content. In some cases they are not fully accurate. We try to have a high viewing pleasure, while at the same time create as little confusion as possible. Thus we aim to only use them when it is clear that they are not directly related to the discussed content.

You know whats crazy?
2020 i felt into a coma for 4-5weeks.
When i woke up i wasn't able to speak but wanted to tell me father "please take me home". So i showed him & the nurse bring me a piece of paper and a pen. So i wrote "dad please i wanna go home now" .. but my dad couldn't read it neither the nurse. I was sooo angry why they wouldn't understand what i wrote. Like 2 weeks later i was allowed to go home and i found that piece of paper. I just made scratches on it...but 2 weeks before when i wrote it i was 100% sure i wrote sentences.
The anton syndrom seems very familiar...
What an scary but also fascinating story! I hope you have fully recovered now!
@@real.psyched thank you 🙏yes i'm fully recovered.🙏
I hope ur all good now!!
You want in 4-5 week coma and recovered? Your lucky I want in a coma for like 1 and a half or 2 week coma in September 1 2022 and I didn't recover instead I'm disabled now ☹️ and tomorrows September 1 so that marks the 2 year anniversary of being disabled now
What lead to the coma?
This is so interesting! The brain is an amazing thing
It absolutely is! Thanks for watching! :)
Indeed !
What happens if you ask them to draw what they see?
Simple, to them they will see themselves drawing something legit, but to us it will be chicken scratch.
@@ese_JONNYX3😟
they're still blind man
They Draw Exactly Hippo if u Ask them to Draw Ant.😃😂🤣
They draw nothing and then confabulate that they've drawn the thing they saw 🤔
As a legally blind person, this is fascinating. Like, seriously, I can’t fathom not knowing I couldn’t see.
Addendum:
Since there are people who are clearly ignorant about blindness and most likely disabilities in general and not inclined to take five minutes and educate themselves on a topic before they comment:
ALL SMARTPHONES have something called accessibility features. These are things meant to make technology accessible to those of us who blind, have motor issues because of conditions like cerebral palsy or other issues such as neurodegenerative diseases like AlLS, deafness or hard of hearing, and those with speech disorders. I, myself am able to type on a smartphone because I have taught myself exactly where the keys are on the screen. I keep a feature called Voice Over running so I can read if I’m in lighting that will not allow me to use the magnification feature to read if I wish. As for typing using a physical keyboard, I have been doing so since the age of three. If you are able to touch type, can you not fathom that someone with little or no sight is capable of the same? Just because you have the impression you would be unable to do anything without perfect vision, does not mean that I am limited by your narrow minded views.
No, I cannot imagine a life in which I have no insight into my disability. I know nothing of life without them. Only 10% of all people considered to be blind see nothing at all. Another fact you would know if you had bothered to educate yourself on the subject. I am neither helpless nor incapable. I am able to cook for myself and my son, clean and care for my residence and child, navigate my way around public places and other things. I cannot drive for obvious reasons, but I can take trains, buses, subways, rideshare, etc. blindness is not the pitiful state you imagine it to be.

@@tgmtf5963 how ?
@@tgmtf5963dude wtf is wrong with you

Very interesting! Great video!
Thank you! :)
nice video, well articulated
Thank you! :)
really,You have explained the matter very clearly ,Alhamdulillah
Thank you!
Alhahm-what now?
i think it means thank god or something like that
@@kowhaifan1249US/Europe citizen trying not to have a seizure when seeing anything Arab or Islamic
@@O_GomesteinIt's more like "Praise due to God" but it's close enough
Keep it up, amazing video.
Thank you! :)
So is it like hallucinations? And do her eyes react to what she thinks is there or what is truly there?
Okay, I get it, she is blind but doesn't know. What does she see at all?? Every video and mention of anton syndrome I've seen never describes what anton patients see
Probably just blur
If you close your eyes, can you imagine sitting in a living room from your own point of view? If the answer is yes then you see what they can see
@@anthonyknight170so all they can "see" is their imagination
@@PuppiesAreNice. yes but is molded by their memory and senses.
@@anthonyknight170okay but one man was diagnosed to be blind from death. If you haven't seen the real world yet how do you imagine it?
So interesting!
great video very interesting!!
Thank you!!
Plots twist:
You have this symptoms while watching this
No 😡
thank you so much
It was impressive 😲
How do they move about? Wont they notice they are knocking into things?
thank uuuu
Thank you.
Thank you for watching! :)
What if I have it right now and these comments are my mind
Love the video, the pace OP talks is horrid. As a dude fr NY my dude talk more fast and more assertive.
I can't understand, it's totally irrational, even after 1 week of seeing nothing, she can't think like have a real reflection on herself adding every clue that she's blind ?? is she a zombie or a robot without any consciousness, just acting with her memories and knowingness how to live normally but without the ability to have a real step back on her situation ? Human are very rational, they are 100% rational every time and even the cognitive bias can be understand by us and we can recognize logically that we have them and stop acting wrong. But that, for my opinion is maybe link with consciousness
Any of us could have it and not know it
She kept running into walls and said she's not blind ? What an idiot 😂 just kidding
Bit insensitive, don’t you think?
What would be scarier? Having a world that is basically fake going into your eyes or invisible walls? She probably had other problems with her brain. Calling her an idiot is a defense mechanism as it sounds horrifying
Sounds horrifying calling her an idiot is comforting i guess
