Today I received my Moms assessement results the letter which was also sent to her family doctor (she agreed to this). My mom has scored 16/30 on the MMSE test indicating moderate cognitive impairment. It indicated she was still driving but did not say stop. It requested a brain scan and she is to start on Aricept after this and an ECG as she also has heart disease. I am in Canada with this diagnosis but coming over in April. I am phoning her family doctor to see if these further tests can be done when I am in the UK. my question is should she be driving with this result? and what does moderate cognitive imparment mean.
