Very good lesson. Thank you! My attempt at summary: Three things in the brain. 1) brain mass/volume (brain cells I guess?) 1300 mL 2) Blood 130mL (supplied by a main artery) 3) Fluid CSF 130mL (Which suspends the brain matter? "Perfuse"? Gives the inter-cranial pressure ICP) 3:00 Brain pressure (CPP specificailly ) must be in a certain range in order to give brain cells and neurons enough OXYGEN and NUTRIENTS to surive. CPP = MAP - ICP (mean arterial pressure - inter-cranial pressure) So if the pressure is not right, your brain will not function well. 5:30 causes of head pressure (ICP) too high = if any of the "three things in the brain" increases. Firstly, brain mass can increase due to tumor, abcess, edema, brain tissue bleeding. @6:00 Secondly, brain fluid (CSF) can increasue due to the following. Note that CSF is constantly produced and recycled within the head/brain, the brain stem, and the brain venous system. So, too much CSF fluid production OR a blockage in the CSF drainage can cause pressure to increase. @7:00 Thirdly, cranial blood pressure can increase due to high venous pressure due to previous heart failure? @7:10; high CO2 level hypercapnia; @7:40 symptoms of high cranial pressure: GCS Glasgow coma scale decreases (indicates brain funtion) ? headaches - because eninges layer stretches. 9:00 vomiting - because vagus nerve is pressed or irritated 10:00 papilla edema (optic disc swelling) because venous drainage is not good. Cushing reflex triad (high blood pressure, irregular breathing, low heart rate) 11:40
I am absolutely mindblown at the high quality information contained in a 15min video compared to my 3hours lecture. Thank you so much for making med school (and life) easier!
For those who suffer from intracranial hypertension and are not responding to drug therapy (acetazolamide and/or topirimate), check out venous sinus stenosis and the option for stenting. Dr. Athos Patsalides and Dr. Waleed Brinjikji are two of the leading docs you can find on RUclips for further information on this condition that is prevalent in a high percentage of people who suffer from pseudotumor cerebri/idiopathic intracranial hypertension.
This is a mLgreat, educational video for new nurses like me! Except the sound was low, making it difficult to hear, even with the volume all the way up. Please keep making more videos!
I'm not a doctor, I watched this to understand my condition better. My ICP was 40mls, at my last lumbar puncture I can not stress enough how much pain my headaches cause, my eyes hurt everyday too. Hopefully treatment will help soon.
Thank you so much! Especially about the Cushing reflex! (The triad) I was diagnosed a while back but I don’t really understand it. I have these headaches everyday but don’t have the eye problem so don’t need the shunt (not that I’m complaining) I just wish the medications worked better. I’m miserable everyday. At least I understand a little more. It’s helpful.
Had to comment and tell you how insightful and informative your video has been. Diagnosed with IIH in 2010 after I experienced extreme headache, vision disturbance, I was unbalanced, had tinnitus and the list goes on but you are the first person that explained the vomiting to me!!! Im not a medical student but a lot of this video made sense and for that I thank you.
I lean toward idiot cat-scan procedures- goes with THIS TOPIC- Doesn't it? Asked for a MRI with conrast- Dr Doofus scheduled a Catscan without contrast- now I know a LITTLE MORE but didn't rule out what I'm fearing - Chiari 1 manifesting at this 😉later time in my life- now I have to drag myself to a larger hospital- with people who possibly have the knowledge I need. Dr Doofus said " I've never had a patient with THAT!" WELL WELL H.E.L.L.O! Maybe You do Now!
I just went in for a blood patch for a csf leak as I get positional headaches. Turns out my csf pressure was actually high (27). They lowered it and I didn’t get a blood patch. I’ve been dealing with morning headaches for about two years. Although I’m not sure what the root cause is, this video blew my mind.
Just diagnosed with this condition. Thankful to know what’s wrong but so annoyed it took so long to get diagnosed. I’ve had double vision, dizziness and tinnitus. I was told there was nothing wrong with me and that it’s impossible to have double vision in both eyes.
i want to ask something sir regarding meningeal stretch and the pain stimulated... i learnt from anatomy book by snell that only dura matter is susceptible to pain while other meninges are prone to stretch reception only and the dura matter supply for pain is by some sensory division of Trigeminal nerve(5th CN)... CAN YOU HELP ME IN THIS REGARD?
Wow... My doctors said my sudden high Blood pressure had Nothing to do with my high ICP. Although it came up together with my headaches and increasing icp. My normal bp was always 110/65. Then, 150/100-110. So, when they normalize my icp, my bp Will go down as well? Never had bp problems, not even during my Five pregnancies.
Can a spinal cause this condition? Can being obese contribute to this? Can retraining water such as edema cause this problem? What about going to a chiropractic, would that help.
i just went to the optometrist and found out that my already elevated optic nerve has elevated even more since my last visit and he thinks maybe a tumor or spinal fluid (most likely spinal fluid) might be pushing against it, is this what that would look like ?
Can intracranial pressure elevate when taking drugs like Accutane? I have never expierienced problems with headaches or eyes etc. I am 1 year after my accutane course, and I have been seeing doctors and hospitals for headaches, espiecially pain at the back of my head, feeling of floating without losing balance, severe eye strain, where I can simply not look at computers at all sometimes but my vision stays perfect. I have been checking my eyes, and my eye pressure was elevated but not severly yet. I also have anemia so I am very fatigued. I feel like accutane caused some kind of imbalanced but my doctors wont really see it as a cause. What should I do to check the presssure in the skull? I do not want to get any syringes inside my head :(
I forgot to mention that my eys feel very heavy in the evenings,. its almost hard to open them up, and 3 months ago I used to have attacks at night when my eyes would just shut open suddenly like there was something dangerous. It does not occur as frequent now but really got me worried
my mother too, and then after 2 blood patches it seems to have resolved (MRI indication) but now it's HYPERtension symptoms that are creeping up (and MRi shows possible hemmorage) . Does your brain feel funky too? as in, vibrating sensation whenever you move? and motor skills are affected
" I want to know why, anyone with Cranial Swelling is not put on, cold Packs, Under Arms, in Groaning area, and behind the Head in Neck Area FIRST, to help get the Pressure and Swelling Down, while finding out what is causing the Swelling?" " To me this is A "MUST FIRST!!!!!!!!"
As one who has suffered from this rotten malady I can attest that yes, it feels like the Chinese government could very well be taking up residence inside your skull and banging on gongs in rhythm with your heartbeat.
Just a suggestion : the explanation is clear but to make it more interesting 1) remove the background grainy noise 2) add a very light delightful music is background.
Very good lesson. Thank you!

Excellent video, thank you! Subscribed and excited to see more! Thanks Dr. Matt and Dr. Mike!
Thank you for this video. You explained this much more clearly than all the research I have read on this topic.
Explained in a way in which someone who is suffering from this condition can understand. Thank you 🙏
Thank you for this video! It is very clear!
No speech to express how useful this video is!!!,,,You are really brilliant!,,Thank you sir..
The most thorough and clear video I have seen on ICP!!
And let me tell you, I have seen tonnes of videos
Legend! So much easier grasping this concept hearing it from a fellow Aussie! Cheers :)
thank you! this is the only thing that has helped me truly understand it! thanks!
Thanks Dr Matt! Love your work (Y)
Thank you! This is amazing!
Thank you so much for this video, it was really well explained 🙏🏼💙

Same boat hope you're better!
Same here man hope you get better
Did your doctors give you any clarity on the cause of this condition?
Prayers
My husband's pressure was 50!
This is a seriously good video. Thank you so much.

miwarrior, we do hope your symptoms improve.
Very helpful, thank you.
Very helpful !...thank you doctor
Very very very much thank you ☺
Thank you so much. This was what I needed and more. +1 subscriber
Great explanation .thank you
Thank you. I have IIH and this has helped to understand what my problem is. My symptoms are always relieved by lumber puncture.
How many Lumbar puncture can have ? I’ve been diagnosed in July not yet had a lumbar puncture yet... still learning about this..
Acetozolmide helps keep the fluid and pressure low.
Thank you that was very helpful.
Thank u so much god.bless u
Awesome!!! Thank you!!
thanks dr mike very useful explaination.
thank you!
THANK YOU! A whole hour in class and I didn't understand one bit of ICP. Now, I feel so confident. You are amazing!! THANK YOU!!

Are you anemic? Look up anemia and intracranial hypertension. It will not be discussed on RUclips.
Oh do you still have the ear ringng n whooshing noise in your ear?
Are you get back your vision beacuse i have the same issue
Do you still experience daily morning headaches? How did the doctor treat it?
God bless you sir
Thanks for explanation
Great video sir
Thanks! VERY HELPFUL!!
Thank you...
Great video! I love it!!!!
excellent video and super useful
Thankyou ,very well explained and now I can join the dots
Hi how are you
THANK YOU
Thank u so much
Well explained thanks 😃🙂🙂🙂
That was wonderful
excellent.
Great video
شكرا جزيلا
As far as ICP goes, my favorite is still insane clown posse

Very well explained, now I know why the systolic goes up and diastolic doesn't. Thank you so much Dr.
nice nice , thanks alot
eceedingly nice lacture
What can cause an increase in CSF, which results in increase in ICP?
i want to ask something sir regarding meningeal stretch and the pain stimulated... i learnt from anatomy book by snell that only dura matter is susceptible to pain while other meninges are prone to stretch reception only and the dura matter supply for pain is by some sensory division of Trigeminal nerve(5th CN)...
CAN YOU HELP ME IN THIS REGARD?
My hair was/is in a UK flag shape, wrapped around my head.
I can *_feel the fluid go down my back!_*
I get Whirling Dervishes.
Please how can i download this video...Very educative

Can tongue placement in the mouth increase the pressure over time?
What medication can be used???
sir kya ye childhood se ho sakta hai because i have symptoms of it from my childhood but it is detected when i am 16 yrs old
Cushings reflex - oh Thank you, Thank you. Also, unstable atlas - big problem.
How does it cause Projectile Vomiting and not regular Vomiting?
Can a spinal cause this condition?
Can being obese contribute to this?
Can retraining water such as edema cause this problem?
What about going to a chiropractic, would that help.
i have a question , so that is CCP or CPP thank you
I was diagnosed with it at 2017 and I have abdominal shunt now.
Is your heads ache gone
@@OneDream501 yesss
So happy for you
How Successful are shunts?
@@MrChaitusk3 yes .. so far it's been great
i just went to the optometrist and found out that my already elevated optic nerve has elevated even more since my last visit and he thinks maybe a tumor or spinal fluid (most likely spinal fluid) might be pushing against it, is this what that would look like ?
You may be anemic. Google anemia causing intracranial hypertension.
If patient had gastric bypass surgery years ago and is not overweight, would they still have vomiting potentially?
Can intracranial pressure elevate when taking drugs like Accutane? I have never expierienced problems with headaches or eyes etc. I am 1 year after my accutane course, and I have been seeing doctors and hospitals for headaches, espiecially pain at the back of my head, feeling of floating without losing balance, severe eye strain, where I can simply not look at computers at all sometimes but my vision stays perfect.

Accutane can cause elevated intracranial pressure. Vitamin A in its many forms have been linked to intracranial hypertension.
Can you increase brain volume after losing volume due to a brain bleed/this?
Can stress bring this on.
Can tetracyclines cause this?
❤
Why the change of info? Is it 1400? And 150 each in volume of this?
Hi can high intracranial pressure also dilate the eyes and vision loss?
Yes.
Causes blindness left untreated
𝐭𝐡𝐚𝐧𝐤𝐬 𝐝𝐨𝐜𝐭𝐨𝐫
What brings me to this channel SMH. Going back to see my ophthalmologist
What does it mean if my CCP is high? Should I be worried op? I don't feel so good
I understand d too much vitamin A can be a problem
Sir, l have a spontaneous intracranial hypotension in 2013...CSF leak ....spinal.
How are you feeling now?
my mother too, and then after 2 blood patches it seems to have resolved (MRI indication) but now it's HYPERtension symptoms that are creeping up (and MRi shows possible hemmorage) . Does your brain feel funky too? as in, vibrating sensation whenever you move? and motor skills are affected
Can strangulation cause ICP?
I do not think the formula for MAP is correct. Could you please review? I rechecked and what I am seeing is MAP = 1/3 SBP + 2/3 DBP
do the maths... map=1/3(pp)+dp that's 1/3(sp-dp)+dp=1/3sp-1/3dp+dp= (take the LCM)=1/3sp+2/3dp
" I find it INSANE as to why the Body is Not Cooled Down as much as Possible, FIRST!"
" I want to know why, anyone with Cranial Swelling is not put on, cold Packs, Under Arms, in Groaning area, and behind the Head in Neck Area FIRST, to help get the Pressure and Swelling Down, while finding out what is causing the Swelling?"
" To me this is A "MUST FIRST!!!!!!!!"
How you talk soooo similar to dr Mike !!!
Dr Matt why did you not pursue a dual degree in art? it’s clearly in your DNA!
Haha, classic❤️
11:40 Cushing reflex
if it wasn't for you guys I would have failed all my pathology exams.
