I have a close friend ( female 66) who seems to be having episodes of early onset Demantia. This is someone who has been to my home on many occasions, and lately has had to call to ask what street we live on. when coming over. On several occasions we agreed to meet at my house to go somewhere and on her way here has gotten lost and ended in another town a distance away. What approach should I take to suggest seeing a doctor to address this concern? She's not very submissive so I don't want to upset her, by suggesting she see a doctor for a condition IU think she may have. Any suggestions?
