My mother, 76 years old, was recently hospitalized with a seizure that they determined was due to low sodium that may have been caused or exacerbated by flu. The sodium level stabilized, she recovered and was released. At followup, Dr said he thought she had "a couple of mild cognitive issues," but wasn't specific and didn't seem all that concerned. Said it wasn't surprising at her age. No referral to a specialist, and no activity restrictions. He said she can drive and do anything else she wants. Other than "be watchful for any changes," he didn't say much else.
To be honest, I really haven't seen anything in the way of symptoms, and I've been looking. She cooks, takes care of herself and the house, carries on complex conversations, and remembers details. She had a TIA two years ago, and has hypertension controlled by medications. She was a lifelong smoker but has recently quit and is sticking to it. Other than that, she is in pretty good health. Her CT scans were clear.
Despite the Dr's seeming lack of concern over this. I am concerned. Should I be, or am I overreacting?
