A patient reports difficulty learning new motor skills after a stroke impacted their hippocampus; which sleep-related effect explains this deficit?

💡 Explanation

Motor skill learning heavily relies on hippocampal-dependent memory consolidation during slow-wave sleep; because the stroke impacted the hippocampus, memory consolidation is impaired. Therefore, the correct answer is impaired slow-wave sleep consolidation, rather than altered sleep spindles, cortisol levels, or N1 duration, which are not directly linked to motor memory formation.
