Question

Eli5 What is the differences between early dementia and normal forgetfulness?

In: 18

Answer 1

I have a medical condition that causes extreme “brain fog.”

I forget where my phone is sometimes. That’s normal. Once, I saw a man in my house and got scared — I forgot he was my husband. That is not normal forgetfulness.
