My father is 84, I took him to ENT today and they scoped him in the office. Numbed his nose..... his larynx and tongue didn t respond. Also he whispers when he talks. He has declined rapidly over the past year or so. Falling, not eating, lost interest in TV, music etc . No appetite, weight loss, wants to sleep a lot. The ENT suspects dementia, alzheimer s or parkinson s or a combination.
