Proof Engine Verification: 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) - 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 (thresh结论：已证实（存在未验证的引用） - SC1（顺行性遗忘症（Anterograde amnesia））：2项独立来源证实，海马体损伤可导致新情景记忆出现严重顺行性遗忘（判定阈值：≥2）。两项来源均已验证——维基百科关于亨利·莫莱森（Henry Molaison）的条目记载H.M.「出现严重顺行性遗忘」；PubMed Central（PMC）2009年斯奎尔（Squire）的引用未在对应网址完成验证，但已得到维基百科已验证来源的佐证。 - SC2（技能学习保留）：2项独立来源证实，海马体损伤后程序性/技能学习能力保持完好（thresh
