My mother has lived with us for 3 years. She is 83 and has a long list of health issues... none of which are terminal... just debilitating. In the past 7 months she seems to have declined rapidly both physically and mentally. She used to have her normal forgetfulness but now it seems to have reached a different level. Just this week alone she had a ct scan that i scheduled in the morning for later in the day. She needed to be there at 3:15...which i told her.... by 2:00 she was upstairs ready to go. She mentioned at some point that she had a hair appointment on Friday at 10..... it was Saturday at 1... and she had it written down on her calendar for Saturday at 1! She wanted me to pick up a refill prescription for her. When I got to the pharmacy they told me she just got it refilled 2 weeks ago. She even called it in but apparently didn't remember that she had already filled it. She looked at the date on the bottle and thought it said May so she called for a refill. Also, when she went to her hair appointment she forgot to wear her glasses. Who forgets their glasses and doesn't realize it? She's worn glasses since forever.
Should I be concerned about this? I'm not sure if this is normal or if we are now entering a different phase. I am very new to this caregiver role and feel we are early in the journey so I don't know how to recognize signs and symptoms of mental decline and fear that I am just overreacting. My sister was very concerned when I told her about our mother forgetting her glasses. That's just not like her. Any advice would be greatly appreciated and additional background supplied if necessary.
