My husband, who has VaD, has started saying it is cold a lot of the time, even in hot weather. He is very unkeen about having the window open at night in the bedroom, yet has night sweats. It is as if his thermostat is out of order. This is becoming a bit of a sore point, as I am not keen on spending night in bedroom with sealed up windows with someone who sweats so much. He has always had an appalling sense of smell, so is unaware of any personal freshness problem, and gets irritable when I complain. Is this anything to do with his condition, or entirely separate? Years ago his night sweats were much worse, to the extent that he had a well man check up which revealed early stages of prostate cancer, which was successfully treated.
