The aneurysm itself was at the edge of my thalamus. The resulting swelling caused damage kind of all over the place.

The functional damage at first was pretty severe, but I don't remember specifics; I mostly don't remember that week at all and much of what I do remember I'm fairly certain didn't actually happen. I spent it in an ICU. I come back to a coherent narrative about a week later; at that point, the bulk of the functional damage was general pain and fatigue, right-side hemiplegia (my right arm and leg were not quite paralyzed, but I lost control over them), mild aphasia which most often manifested as anomia (difficulty retrieving words) and occasionally in other ways (I remember losing the ability to conjugate sentences for a few hours; that was freaky), and (most significantly) a loss of short-term memory with all the associated knock-on effects to various kinds of cognitive processing.

There was also a lot of concern at various points that there may have been damage to my emotional centers. I never noticed any such effect, but, well, I wasn't necessarily the most reliable witness. Most memorably, this led to one doctor asking me if I my emotional state was at all unusual. I didn't reply "What the fuck kind of a stupid question is that, I just had a fucking stroke, of course my emotional state is fucking unusual you inbred moron!!!" although I really wanted to. I instead replied "I'm pretty sure my unusual emotional states are situational, not organic." Ultimately they started believing me.
