2. Memory loss
What’s normal: Everyone is prone to forgetting the occasional appointment or temporarily blanking on a person’s name. This may become more common as we age, but doesn’t necessarily mean Alzheimer’s. You needn’t worry if the information comes back at a later time or when you’re given greater context.
The warning sign: It is typical with Alzheimer’s to forget information that was recently learned. This is often noticed when a person asks the same question repeatedly, forgets important birthdays, or begins to rely more heavily on memory aids like notes or electronic reminders.
