Ask CashDoc [Forgetfulness]

I have severe forgetfulness.

My mother is in a nursing home due to dementia.

I was worried that it might be a pre-dementia stage.

I'm afraid to go to neurology, so I can't go.

Therefore, coffee on the internet is said to actually help awaken the brain and improve concentration.

I haven't drunk coffee for several years because my stomach hasn't been well. I only drank it when it was absolutely unavoidable.

How can I improve my forgetfulness?
