    Let’s take a look at ischemic stroke syndromes. Pure motor hemiplegia. Contralateral pons or internal capsule lacunar. In a vascular pathology, you’re going to have these larger arteries that are affected. Let it be the middle cerebral artery, anterior cerebral artery, so on and so forth or there’s something called a lacunar infarct. Let’s say that your patient has had long-term hypertension. Remember we said that hypertension is an extremely common risk for stroke taking place. And if the hypertension is taking place over a long period of time, you can only imagine that there is really no blood vessel that is left safe, right? So they’re all vulnerable to some type of pathology. And say that you have a little blood vessels that are now undergoing compromise and undergoing damage and injury. And at some point in time, maybe there’s an aneurysm that takes place and this aneurysm could be something like a Charcot-Bouchard aneurysm. And that particular aneurysm would be one in which little blood vessels, deep penetrating blood vessels of the brain that are being affected. So imagine that these little blood vessels especially around the internal capsule, which is responsible for motor functioning on the contralateral side, right? So think about that from neuroanatomy, please. And at some point in time, as the aneurysm gets bigger, we know that any time, there’s an aneurysm taking place. You’re always worried about rupture, aren’t you? And so therefore, when there’s a rupture that takes place, and you can only imagine now the little blood vessels, well, they’re infarcted. And you call this a lacunar infarct. And many times, patients with hypertension will have lacunar infarct. But if that part of the brain is not significant in terms of proper functioning and then the patient may be asymptomatic. But...
