Hi there ~
I understand your concerns. Being old aged and weak and unable to finish sentences, while you are recovering from a bout of bronchitis
is a sign of an illness that would otherwise be called dementia
. However you do not need to worry, and there are many long term care facilities that can care for the situation your grandmother is facing. Sleep difficulties add to the problems. An evaluation by a geriatric psychiatrist
or a geriatric specialist internist might be able to give you the right direction regarding treatment and disposition.
I hope this helps. Take care and have a lovely day!
