Hi, does anybody know if seeing people who are not there is another symptom of dementia? My OH constantly wakes up after a nap asking where so and so has gone or stares ahead talking to someone thinking they are there. Also what does 12 errors on the MMSE mean? Our GP says it was enough to trigger a referral to the memory clinic. I think my OH only had 2 errors on his first MMSE 2 years ago. I've been noticing problems for nearly 3 years, why does it take so long to get any diagnosis. It's always been put down to stress and anxiety. I feel like precious time has been wasted when he could have been on treatment to slow down progression. I feel so scared.
