impair the storage and maintenance of memories.?

all of these

Yes, the answer is "impair the storage and maintenance of memories." Sleep deprivation has been shown to have numerous negative effects on cognitive processes, and one of them is impairing the ability to store and maintain memories. Lack of sleep can disrupt the consolidation process, which is important for transferring information from short-term memory to long-term memory. Without adequate sleep, the brain's ability to retain and recall information can be significantly hindered.
