Undiagnosed grandmother
No official diagnosis but her cognitive and physical abilities have been declining steadily for a few years. Still the doctors don't give an official diagnosis. She's extremely forgetful and sometimes does stuff that's a tad weird but nothing extreme.
She takes the same route to a neighbouring town to do her groceries. Our town has multiple, but she goes there because she used live there. She's still able to drive a car (although she shouldn't) but if there is a road block she will just get out of the car and call my father to come save her.
This is where my problem lies. The lack of diagnosis makes me feel like she's just not trying anymore. She doesn't take the effort to think. It feels like she has given up. She sleeps all day as well, doesn't go out or hang out with friends, barely eats. It feels more like a depression.
Is this dementia? If so, is the passivity towards life (i.e. her giving up) a common symptom? What do we have to do to get a diagnosis?
