Memory loss issue. A prescription?

Namaste Doctor, for the past few years I have been experiencing some memory-related issues. I have difficulty recognizing the faces of new people whom I have met only briefly, even though they recognize me easily. I also sometimes have difficulty remembering things, and my brain often feels heavy or like there is pressure in my head. I would like to know if these symptoms could be related to any imbalance or other issue that can be addressed through Ayurveda. Could you please suggest any general Ayurvedic medicine, supplement, or safe OTC option that may help with memory, concentration, and mental clarity, which can be taken without a prescription? If there is anything I should avoid or any basic tests that you would recommend before taking something, please let me know. Thank you, Doctor.
