Anyone have a problem remembering?

I know my age plays a huge part in my attention to details. I have notes written to SELF. Yet the conversations I have even with those close to me often get Scrambled. I'm looking for something I might purchase over the counter something that might provide me a BOOST to my BRAIN! I will turn 67 this week. And day by day my memory is becoming worse. This morning I had to call my daughter to tell me my bank password. Wasn't expecting to have my brain wiped clean and clear.
