Can we talk about early-onset Alzheimer’s? Specifically, how early is “early”? (Like, is 27 early?) And how does one tell the difference between memory loss from Alzheimer’s and memory loss from, say, lack of sleep and excessive multi-tasking? Anyone who is capable of reading a WebMD page without self-diagnosing is qualified to answer! BONUS: What about brain tumors and memory loss? Causation? Correlation? Commiseration? Constipation? Asking for my dog. I mean a friend. I mean my dog.
