Окей. So, we were told about... Um, CNS cases. And, uh, the thing in CNS case is that with your history, you get-- you come to a diagnosis, like whether it is a thrombotic, whether it is a embolic, or whether it is a hemorrhagic stroke. Okay. So in the stroke history, when you come to a diag- diagnosis, taking the history of presenting illness, like, um, uh, to distinguish between a thrombotic, embolic, and a hemorrhagic stroke, and you come to a site of the lesion, uh, and you think about the pathophysiology and the etiology. So make... A chart where I would think that this... if these, these, these things happen, then it is a embolic shock. If these, these, these things happen, then it's a thrombotic shock. If, uh, other things happen, it's a emphymeratic shock. For example, like, uh, I gave you an example of a gardener. Uh, so, uh, if, uh, while doing gardening, if a person feels like, uh, he, uh... there is weakness of his right upper limb and lower limb, and such that the power becomes almost zero at that point, then what kind of shock is that? Like, what kind of stroke is that? And the ones where gardener thinks that, you know, he is feeling that his right upper limb and lower limb is weak, but he could still continue, and with time, the power becomes zero, then what kind of a stroke is that? Whether it is thrombotic, whether it is embolic, what kind of a stroke is the stroke when you get up in the morning? That kind of stroke is thrombotic. Then when do you think of a hemorrhage? When do you think of a icy bleed? And, or after you get the site and the type of the stroke, what are the things, uh, negative history that you rule out to know that this is embolic or this is thrombotic and this is hemorrhagic? And whether it is embolic, then this is not thrombotic and hemorrhagic. What are those negative histories? Also, the comorbidities that the person has, like a young patient having hypertension will have different, uh, negative histories for the stroke to happen. It won't be a car- cardiac disease. The hypertension could be because of something else. Uh, the old , uh, patients having, uh, cardiac disease might be having stroke because of cardiac disease or any other reasons. So a- again, age-wise differences between, uh, negative histories, um, then, uh, yeah. So give me a very detailed idea using, um, standard textbooks of medicine, uh, so that I can take proper detailed histories and write negative histories in case of embolic, thrombotic, hemorrhagic shock, and even the icy bleeds, uh, and even, uh, according to the region of the stroke.
