Just that really.
Late 60s, active, likes a drink (possibly daily, not to excess).
When I saw him today he just seemed a bit 'off'. He is usually quite sharp and quick witted, but not so today. He repeatedly wiped at one side of his mouth with the back of his hand and had a really vague, almost confused air about him, almost as if he was a bit tipsy. I mentioned to DH that I was concerned and he said he hadn't noticed anything unusual when he'd spoken to him, although his dad had said he felt very cold.
Any ideas what might have caused this? My immediate concern was a stroke type episode, but as time went on he perked up a bit and became more like himself.
