Is it true that one night of total sleep deprivation impairs next-day attention and working memory?
Partly. Multiple studies and reviews indicate that total sleep deprivation impairs attention and working memory, though several focus on longer deprivation periods or specific populations. One study of older adults found no working memory impairment after one night of total sleep deprivation, so the evidence is mixed and does not fully settle the claim as stated.
