My mother was diagnosed with dementia which doctor said will definitely progress to Alzheimer's and she has been living with me for few months now. Of late she seem to have a foggy brain especially in the morning after she gets up and towards the end of day. I see everyday occurrence of at least one symptom. She seem to have lost her presence of mind. Things like she would tell me that someone told her about certain thing that I would have actually told her. She is physically active, goes for an evening walk with me, cooks meal perfectly to taste. She will be here with me for about 2 weeks before she goes to my sister's place. I am wondering if these are dangerous signs yet? Can the symptoms possibly become worse in next couple of weeks? Thoughts?
