Maria is a 3-year-old who has been diagnosed with CIPA, or congenital insensitivity to pain with anhidrosis. This disease results from a genetic mutation that causes essentially all general sensory neurons to not function properly. What types of sensations will Maria be unable to detect (be specific)? Predict what problems she might face from her condition.

Welcome back, everyone. Here's our next question, Jenny experiences increased sensitivity to pain stimuli, even those that are mild or typically non painful. What condition might she be experiencing? A paresthesia? B, dysesthesia, C hyperesthesia or D analgesia. Well, here's a case where our prefixes can really help us. So we have increased sensitivity to pain stimuli and that can lead us to our answer choice which is choice C hyperesthesia. Again, remembering that hyper is that, is that meaning of more or greater? So, hyperesthesia is a an increased sensitivity to sensory stimuli, including pain. So to be thorough, let's look at our other answer. Choices. Choice. A paresthesia would be when there's an experiencing of abnormal sensations such as tingling or numbness. So that's why A is not our answer. Tri B dy aia would be when they are unpleasant, abnormal and sensations. So there again, we can be guided by that prefix of dis to let us know that they are unpleasant, but again, not an increased sensitivity, just experiencing these abnormal sensations that are unpleasant. So that's why choice B isn't correct. And finally, analgesia, you might know if you think of an analgesic, this would be a reduced ability to perceive pain. So you take an ibuprofen that's known as an analgesic and analgesia, is that the opposite of hyperesthesia? So, it is obviously not correct. So once again, if someone's experiencing increased sensitivity to pain stimuli, even those that are mild or typically non painful, this condition would be known as choice C hyperesthesia. See you in the next video.
