my OH was diagnosed 4 years ago and only deteriorated very slowly. He takes Aricept religiously. But he won't talk about his illness to anyone, so we don't. For the past two months he's been getting iller. Can't finish sentences, can't see things directly in front of him etc etc, tho in many other ways he's fine. But my question is : does hot weather have an adverse effect ? I'm finding him very fussed and flustered in this hot weather, and if so will cooler weather make him a bit less confused ? . Just hoping a bit, and because in future we could avoid going anywhere warm on holiday if hot weather might be a factor. Thank you for reading !
