I've heard a goldfish has a very short-term memory. Are there cases like that with humans too? I mean not like of old age, but rather even when still at a younger age.

Can you define your terms a little more?  What do you mean by "short-term memory" and "human"?
assistant
By "short-term memory" I mean someone very forgetful. I think there was even an Indian movie like that where the guy had to tattoo a map (or notes, can't remember exactly) on his body just to remember things.

That reminds me of the famous example of Henry Molaison, a man with extensive brain damage as the result of a terrible motorcycle accident. The damage caused extensive loss of long-term memory. I think this was also documented in the movie "Memento", which stars Guy Pearce. I think the full story is pretty incredible and was the focus of some fascinating research, but I don't know what we have here now that would be enough for a good summary.

Sorry, I think you're wrong about the "Henry Molaison" one. It wasn't exactly due to a motorcycle accident.
user
Sorry, I know we can both be wrong, but I could still probably find a good source of information on him, and what his memories were like.  Would you like me to do that?
assistant
Sure.
user
Great, thanks.  I've found a pretty interesting article here from the Harvard Magazine.  Let's go to the main point in that article:

In a manner only partly predicted by psychologists, Molaison’s deficits were primarily semantic, and not amodal. He had no trouble with spatial memories. As a teenager, he could draw intricate maps of the streets around him—landmarks he’d never forgotten. Nor could he recall large-scale events, such as what happened on any given day. When his mother died in 1985, he had to be reminded of her existence by reading a family scrapbook.

I can't verify if what you just said is exactly correct, but that's interesting to know at the least. Thank you for taking the time to answer my questions!

You're very welcome!

No problem! I’m glad I could help, or at least introduce you to some sources of information you could also read and find more answers to your questions.
