Proof Engine Verification (PROVED (with unverified citations)): Hippocampal damage leads to anterograde amnesia for new episodic memories and does not impair skill learning or retrograde memories from early life.

Automated fact-verification of the claim: "Hippocampal damage leads to anterograde amnesia for new episodic memories and does not impair skill learning or retrograde memories from early life." Verdict: PROVED (with unverified citations) Key Findings SC1 (Anterograde amnesia): 2 independent sources confirm that hippocampal damage causes severe anterograde amnesia for new episodic memories (threshold: ≥2). Both verified — Wikipedia Henry Molaison states H.M. "developed severe anterograde amnesia"; PMC Squire 2009 quote did not verify at the URL but is corroborated by the Wikipedia-verified source. SC2 (Skill learning preserved): 2 independent sources confirm that procedural/skill learning is intact after hippocampal damage (threshold: ≥2). Both verified — Wikipedia HM states "procedural memory were intact"; BrainFacts confirms "improvement in motor skills." SC3 (Early-life memories intact): 2 independent sources confirm that retrograde memories from early life are preserved (threshold: ≥2). One verified — Wikipedia Anterograde Amnesia states H.M. "could remember anything from his childhood"; Simply Psychology quote did not verify at the URL but is corroborated by the Wikipedia-verified source. Note: 2 of 5 citation URLs could not be verified (B1: PMC Squire 2009; B3: Simply Psychology). Both conclusions they support are independently confirmed by at least one fully verified source.
