hello, my sister is getting ready to turn 31 next month. she has been experiencing memory loss for some time now. I m not sure about her, but I m getting a little worried. She is a stay at home mom of 4 children. Two of which are 2.5 year old twin boys. She doesn t take any meds. She doesn t currently have any existing issues other than her memory loss. It s short term for the most part. She can recall some things about childhood. Not much though. It s the little things. Setting a date and time to do something only two days away, and we have to call her each day to remind her. Or she won t show up. Also, if we do something together or have a conversation about something and a few days later, couple weeks, or a month even, and she doesn t recall the conversation. It s completely gone! And it could be a very important conversation. Not just like something about everyday events. Should I be worried?
