Mom is 91, post stroke, chf and repaired broken hip. She was dxed with Vascular dementia after the stroke and mild cognitive decline a year before that. She also has aphasia from the stroke, so often it's hard for her to tell me things. She mentioned today that in the last two days, she's had an "episode" of "not knowing what to do next". She wasn't able to elaborate, but I asked if it was like when you're driving around a corner and suddenly nothing looks familiar for a second. She said yes, it was like that, so we gave it the name "brain freeze". Is this a symptom of something? Mom has a DNR and DNI and we're pretty much done with tests and procedures.
