Dementia Alzheimer's disease?

I finally had my doctors appointment. I gave him all the new symptoms I have been dealing with. He had me take a 2-part test, cognitive impairment and mmse test. He never said how bad or good I did but said I did not do so well. Because of my score on the MMSE test he prescribed me Donepezil 5mg to start off with and has referred me to a Neurologist that specializes in dementia. Can anyone tell me what's going to happen next?

Go for a second opinion ??are you dealing with brainfog and cognitive issues ?
