I have short term memory loss. AMA
Back in 2005, I was diagnosed with a very rare brain tumor (I was the 3rd person in the entire world to be diagnosed with it.) After four brain surgeries I went through radiation treatment which killed the remaining cancerous tissue, but resulted in me being left with short term memory loss. I was 13 at the time of diagnosis and I am now 20.
EDIT: I'm not really sure how to prove this, but just let me know whatever is needed for confirmation.
EDIT 2: The type of memory loss I have is called Mild Cognitive Impairment
"A subtle increase in memory loss may be an indication of mild cognitive impairment (MCI). The memory problems can significantly affect victims, but the symptoms are not as severe as those associated with Alzheimer's, according to the University of California, San Francisco. People with MCI may start to have difficulty remembering the names of people, maintaining a conversation due to forgetfulness or remembering where they placed items. However, the person with MCI is often aware of these difficulties and tries to compensate by writing messages or notes to help remember. He may be able to perform many activities without help. But his mild memory loss may interfere with planning or the ability to remember events and objects."
