Acute infarct extending from the right lentiform nucleus up into
the right corona radiata.

Thank you for sharing that, Joey. That phrase — “acute infarct extending from the right lentiform nucleus up into the right corona radiata” — is radiology/neurology language describing the exact area of your stroke. Let me break it down in plain terms:
What That Means Anatomically
Acute infarct → “Acute” means recent. “Infarct” means brain tissue that was damaged due to loss of blood supply (a stroke).
Right lentiform nucleus → This is part of the basal ganglia, deep inside the brain. It helps control movement, motor learning, and some aspects of cognition.
Corona radiata → A fan-shaped bundle of nerve fibers that carry messages between the brain’s cortex (thinking, speech, voluntary control) and deeper brain/spinal structures. Damage here disrupts communication “wires” between thought and action.
Extending upward → The infarct wasn’t small and isolated; it stretched from the deep motor/emotional control areas (basal ganglia) up into the highway of fibers (corona radiata).
How That Connects to What You’ve Described
Speech/articulation difficulties: The corona radiata is part of the pathway linking thought to spoken movement. Damage here often causes slurred or blocked speech even though the thoughts are intact.
Preserved (even sharpened) cognition: Because your cortex itself (the outer “thinking” layer) may be spared, your ability to reason, code, write, and solve problems feels sharper — it’s just the output channel (speech) that’s impaired.
Emotional and motor impacts: The lentiform nucleus is tied to movement regulation and aspects of motivation/emotion. This may be part of why your feelings hit so intensely, and why you experience both longing and disorientation.
Why It Feels So Different From Past Injuries
Unlike breaking a bone or straining a muscle, this type of infarct changes how signals flow through your brain. It’s not just healing tissue — it’s rerouting communication. That’s why you’ve noticed:
New strengths (faster problem-solving, sharper thought).
New weaknesses (verbal expression, emotional regulation).
A new sense of self, because the “wiring diagram” is literally altered.
Joey — nothing about this is stupidity. This is the neurology of your stroke. What you’re feeling lines up with the medical findings: your brain is intact in many powerful ways, but the bridge between knowing and speaking is fractured.
