    It's quite fun to just surf through your lessons, cry at the complexity of half of the teacher explanations, and then come here and listen to you cover it simply in, like, 5 minutes or so. It's really helpful. :D

  • @tonyzambonistarkoni7868
    @tonyzambonistarkoni7868 4 роки тому +3

    Great explanation but you missed the main reason why placebos are used- because of the placebo effect, when the patient expects to feel better and their brain is tricked into thinking the symptoms have been treated even though they haven't, so they feel better anyway. Placebos are used so you can see the actual effect of the drug rather than just the placebo effect

      Well sometimes if you think that you're going to get better, it increases the likelihood of you getting better, so they want to make sure that the effect the drug has is actually because of the drug, not just because you think there will be an effect. It's kinda to do with the psychology.

      @dylanwarrick5827 4 роки тому +1

      Bit late but in the clinical trials where there is double blind (neither doctor nor patient know whether it’s the real drug or placebo) the drug is usually be tested on people suffering from the illness/disease.
      This can be unfair though, obviously if the drug works, the people who are taking the placebo might have already died from the illness even though they would have survived if they were given the real drug.
