    CPP Normal Range : 70-100 mmHg, ICP Normal Range: 5-15 mmHg, B-Brandypnea, and A- CT scan of the head. CPP = Mean Arterial Pressure (MAP) - Intracranial Pressure (ICP). MAP = (Diastolic BP x 2) + Systolic BP / 3. Thank you.

      @@WizKidNas In general, X-rays shows bones well, but aren’t very good at finding soft tissue problems.
      Specifically, for this patient: elevated BP + bradycardia in a patient with a positional headache...Medicosis is telling us that there is Cushing Signs in the setting of what could be a brain bleed (or something sloshing around in his head). That’s bad. And likely a brain problem, not a skull problem. CT better for soft tissue (and actually fantastic at picking up acute bleeds)

    Awesome video, and you have a good sense of humor. My 36 year-old son has been diagnosed with first mold toxicity, but his lowered immune system let a diagnosis of Lyme, Babesia, and anaplasmosis. Then, he got Covid after Christmas in Jan. 2022, and his head pressure went through the roof. He’s still in horrible pain, and it’s 8 months later. He’s seeing 4 different types of specialist doctors, and is being treated for these infections, but no one can figure out what, exactly is causing this excruciating pain. He sleeps with ice packs, has lost a lot weight, and barely gets up. He does have forward head posture, and I’m not sure if that’s keeping the pressure in his brain, but he complains all day long when he doesn’t sleep. He also has horrible nightmares, hallucinations (cut back his meds), delusions, paranoia, depression, anxiety, and I’m going nuts, as his mother! He’s had meningitis at age 7, several severe TBIs, and now this. I was told it was either the mold or the Babesia, but I also think, by his neck placement, it could be cervical instability. He won’t go back to the upper cervical chiropractor I was taking him to, although his neck felt better, but maybe I should try it again.
    He’s going for neurofeedback and hypnosis, but I’m not sure these will work if there’s a physical problem.
    Can ANYONE tell me what this could be? He’s ready to jump off a bridge and can’t stay by himself for more than an hour. He’s scared to death! I am too!

    This is fantastic. Could you talk a little about the timeline of this process? For example I’m guessing stomach ulcers take time to form so can a person have Cushing signs but still be alert and orientated? For example , the question at the end has a person experiencing a Cushing a triad but a gcs 15 and has been suffering this for 3 weeks . I’m a uk paramedic and we tend to associate these symptoms only with acute onset and greatly reduced gcs patients.

    at 4:28, he says CN6 palsy, but this is supposed to be CN3 palsy (oculomotor n.) due to compression against the clivus bone at the base of the skull; this results in ipsilateral dilated and nonreactive pupil and later the "down and out position" of the eye (parasympathetic fibers surround the motor fibers in the nerve and thus are affected first).

    • @MedicosisPerfectionalis
      @MedicosisPerfectionalis  2 роки тому

      Then why do we commonly see CN VI palsy in cases of idiopathic intracranial hypertension?

    • @michaelthompson3483
      @michaelthompson3483 2 роки тому

      @@MedicosisPerfectionalis I wouldn't say "commonly" as it is a rarer symptom of IIH. CN 6 is most commonly affected in IIH, but IIH in and of itself is a rare disease that usually affects young overweight females, and it is usually chronic or subacute, not an acute emergency as your video says. Thus, you don't really see the Cushing reflex in IIH. There are other more common causes of emergent intracranial hypertension that affect a larger number of people and include a wider variety of patients. In these cases, brain herniation is the biggest threat, and the most commonly seen cranial nerve involvement is CN3 for the reasons I stated before.
