Although she is in age of 80s and most common memory problems come with this
elderly age as an Alzheimer’s disease, but it is essential other possibilities of
memory loss and other symptoms like hormonal imbalance, stress/depression, and vitamin deficiency need to be evaluated thoroughly. In this disease, normal day-to-day activities have been affected more than memory loss. Therefore, I would suggest consulting a doctor to rule out other possibilities first with the help of doctor.
