What Is Vertigo Why Do We Get It
You might think vertigo is a problem thatpeople have when they're afraid of heights.or are Jimmy Stewart. Nope! Vertigo is all inyour head.specifically, your ears. Hey guys, Lissette here for Dnews. Vertigois one of the four main egories of dizziness it's a subjective experience that makesyou feel like you've lost a sense of your surroundings. But there are some very realcauses behind it some cases, vertigo can even lead to nausea, vomiting and youreyes to twitch from side to side. There are two types of vertigo: peripheralvertigo and central vertigo. Central vertigo is a neurological problem usuallythebrain stem or cerebellum which can be caused
things like multiple sclerosis, stroke, andtumors. But the most common by far, and what we'll be focusing on here, is peripheralvertigo. Because, as a 2002 studyThe British Journal of General Practice reports, at least93% of patients with vertigo, are those with peripheral vertigo.which has a lot to dowith problemsyour ears. Your ears are super important for keepingyour balance and navigating the world. They help you orient yourselfit. In your innerear, there are these tiny hairs called stereocilia, that line a pouchlike structure called thesaccule. And interspersed between these hairs, is a sticky goop called glycoprotein thatholds tiny crystalsplace. These guys are
made up of calcium carbonate, and move wheneverwe move, which causes them to bang up against the hairsour ear. When the hairs sensethe crystals moving, they send signals through nervesour ears to our brain that giveit information about our vertical and horizontal movement essentially, these crystals tellour brains where the heck we're going and help us keep our balance. On top of these nerves, crystals, and hairs,we also have fluidour ears. Like the crystals, the fluid moves when we move and that'spicked up by our hairs which send information to our brain. Our brain uses the informationcoming from both ears to figure out whether
we're stationary or moving, and how we areoriented! Vertigo occurs when somethingthis systemgoes wrong. The spinning sensation or dizziness is your brain trying to figure out what theheck is going on. It's getting cues that don't make sense. And a number of differentconditions can cause this. In the cases of vestibular neuritis and labyrinthitis, partsof your ear become inflamed, usually because of a viral or bacterial infection. When oneof your two ears is inflamed particularly the ear's nerves it causes your brainto get imbalanced information so you can end up with vertigo. Meniere's disease, althoughit's not well understood, it's thought
to be caused by too much liquidyour ear,which causes the same dizzying symptoms. And researchers think migraines can cause vertigobecause they cause changesour vascular and nervous systems, which affect parts ofour ears. Finally, one of the most common causes of vertigo benign paroxysmal positionalvertigo has to do with the crystals. Sometimes these crystals fall out of place possiblydue to a head injury or because the goop that holds themplacethe inner ear becomestoo weak. When they fall off, these crystals can end upplaces where they don't belong,like the middle ear, and cause our brain to receive signals that don't make sense toit. They throw everything off!
Luckily, this one can often be fixed by simplyfollowing a set of head movements that move the crystals out of where they don't belong.Invented by John Epleythe 1980's, this noninvasive procedure can be effectivein up to 90% of these vertigo cases. Other causes of vertigo can be treated with mediion,althoughmore extreme cases surgery may be necessary. As nasty as that sounds, some people do undergothese procedures, because vertigo can be horrible. It can last anywhere from hours to monthsat a time and can be debilitating. On top of that, just moments of Vertigo can causea lot of harm. If we lose our balance and
Cannabinoids and Pain MCC Australia
I am Donald Abrams the chief medicaladviser of the Medical Cannabis Australiamy experience 33 years asan oncologist, 17 years as a cannabis investigator. Cannabis ismedicine and it's useful for many refractory conditions for which modernpharmaceuticals either are not effective or too toxic. My group did a study inpatients with HIV related painful peripheral neuropathy or damage to thenerves that causes painthat study we did demonstrate that cannabis wassuperior to placebo cannabis from which the active ingredients had been removedin reducing the symptoms of pain
secondary to the nerve damage. This ledto the current study that we're doing which is funded by our National Heart,Lung and Blood Institute. We're taking patients who have sickle cell diseasecharacterized by chronic pain and intermittent acute painful crises andwe're looking to see if they pariahs cannabis compared to placebo decreasestheir pain decreases markers of inflammation and decreases markers ofdisease progression. This study is really based on work doneby a mouse scientists at the University of Minnesota who has a mouse model ofsickle cell disease that is responsive
to cannabinoids with regards todecreasing pain markers of inflammation and markers of disease progression we atthe medical cannabis Australia engaged promises botanist engineers andsorder to ensure the safest and purest and have enjoyed therapy.
