Answer:
It is quite likely that Aretha will find that the surgery has also affected her ability to "form new memories".
Explanation:
As Aretha had surgery and doctors removed a portion of hippocampus, it affected her ability to create new memories, because hippocampus which is located in the brain have a function related to memory. Hippocampus receives signals and send to the brain via entorhinal cortex, so when a portion of it is removed it will affect memory.
